NEW QUESTION # 21
An OSPF router has learned a pain 10 an external network by Doth an E1 and an E2 advertisement Both routes have the same path cost Which path will the router prefer?
- A. The router will prefer the E1 path.
- B. The router will prefer the E2 path.
- C. Both routes will be suppressed until the path conflict has been resolved.
- D. The router will use Doth paths equally utilizing ECMP.
Answer: A
Explanation:
In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.
NEW QUESTION # 22
A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attribute:
* MAC address=81:cd:93:13:ab:31
The test device needs to be assigned the "lot-prod'' role, in addition the "lot-default" role must be applied for any other device connected lo interface 1/1/1. This is a lab environment with no configuration of any external authentication server for the test.
Given the configuration example, what is required to meet this testing requirement?
- A. Enter the command "port-access device-profile mode block-until-profile-applied" globally.
- B. Enter the command "port-access onboarding-method precedence" to set device profiles with a lower precedence.
- C. Enter the command "pot-access device-profile mode block-until-profile-applied"" for interface 1/1/1.
- D. Enter the command "port-access fallback-role lot-default globally
Answer: D
Explanation:
The fallback role is used as a default role in the absence of a specified role or when an authentication server is not available. Given the scenario, where the test device with MAC address 81:cd:93:13:ab:31 needs to be assigned to "iot-prod" and other devices to "iot-default", and considering there is no external authentication server configured for the test, the appropriate action would be to set a global fallback role that applies to all devices connecting to the network. This ensures that any device that does not match the specific device profile will inherit the "iot-default" role. Since the configuration for a specific MAC address (81:cd:93:xx:xx:xx) to associate with the "iot-prod" role is already in place, setting the fallback role globally accommodates the requirement for other devices.

NEW QUESTION # 24
An ACME company employee complained about a recent poor-quality VoIP call while moving around their office environment HPE Aruba Networking Central reported a fair UCC score for this call while your VoIP engineer reported that their systems reported a MOS of 2, 3. The VoIP devices are operating over the 5GHz frequency band.
What are the possible contributing factors? (Select two.)
- A. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
- B. The client roamed into an area that continuously operates Zigbee.
- C. 802.1K is disabled in the WLAN Security settings
- D. There was localized interference at the caller's location
- E. 802.tr is enabled in the WLAN Security settings.
Answer: A,B
Explanation:
VoIP quality can be negatively impacted by insufficient cell overlap in AP deployment plans, which can cause poor handoffs between APs as a user moves around. This results in a degraded VoIP experience.
Additionally, roaming into an area with continuous Zigbee operation can cause interference with the 5GHz frequency band, further contributing to poor VoIP call quality. The Zigbee communication protocol operates on the same frequency band as Wi-Fi and can introduce noise and interference, which leads to a reduced MOS score, as reported by the VoIP engineer.
NEW QUESTION # 25
In a WLAN network with a tunneled SSID, you see the following events in HPE Aruba Networking Central:
The customer asks you to investigate log messages. What should you tell them?
- A. This indicates a security issue. The client with a MAC address ending with 37:18:0d is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network
- B. There is a roaming issue. Enable Fast Roaming 802.11r and OKC to resolve the issue
- C. This is normal, expected behavior. No further actions are needed
- D. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18:0d.
You should upgrade the client WLAN driver
Answer: C
Explanation:
The provided event logs from Aruba Central show multiple entries of:
Client PMK/OKC Key Add/Update
Client PMK/OKC Key Delete
Operation ADD/UPDATE for key cache entry for client ...
Operation DEL for key cache entry for client ...
These log entries refer to Pairwise Master Key (PMK) and Opportunistic Key Caching (OKC) updates in the Aruba gateway or access point for wireless clients.
When a client roams between APs or the system refreshes key entries for active clients, Aruba's infrastructure updates or deletes PMK cache entries dynamically. This process ensures secure key continuity across APs and controllers for tunneled SSIDs.
Exact Extracts from Aruba WLAN and AOS-10 Documentation:
"PMK/OKC cache updates and deletions are part of normal operation. When clients connect, disconnect, or roam, the system adds or removes their PMK cache entries. These log messages are informational and indicate expected WPA2-Enterprise behavior."
"In a tunneled SSID, PMK and OKC entries are managed at the gateway level. When a client roams or rekeys, the gateway logs PMK/OKC Key Add/Update and Key Delete messages. These are not error conditions."
"Frequent ADD/DEL entries for a client MAC address reflect normal WPA2 key lifecycle events-such as reauthentication, idle timeout, or client-driven disassociation." Thus, these messages indicate normal background key management (PMK caching and rekeying) and not any fault or attack scenario.
Why the Other Options Are Incorrect:
* A. Denial-of-Service attack:False. These events correspond to key management, not excessive connection requests. Aruba security logs for DoS attacks show messages like "Association flood" or
"Authentication flood," not PMK/OKC operations.
* B. Roaming issue:While OKC relates to roaming optimizations, these log messages do not indicate a failure or issue - they show successful key caching updates.
"OKC Key Add/Update events confirm successful key caching, not roaming failure."
* C. Client WLAN driver issue:No error messages (timeouts, EAP failures, or deauths) are logged. The presence of PMK updates and deletes alone does not imply a driver issue.
"Client driver problems typically manifest as association failures or 4-way handshake errors, not PMK cache logs." Conclusion:
The repeated "PMK/OKC Key Add/Update" and "Key Delete" events represent routine client key caching and refresh behavior in Aruba's tunneled WLAN design.
No misconfiguration, client issue, or attack is implied.
Therefore, the correct answer is:
# D. This is normal, expected behavior. No further actions are needed.

NEW QUESTION # 26
A campus topology uses VSX with a collapsed core topology. The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link. You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.
What is a valid configuration?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.
NEW QUESTION # 27
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. What is a valid cause for having an equal split in APs connected to the primary and secondary gateway clusters?
- A. The primary gateway cluster is a homogeneous cluster with four nodes
- B. The primary and secondary gateway clusters are up, but the cluster preemption is not enabled
- C. The primary and secondary gateway clusters are up, and the cluster preemption is enabled
- D. The secondary gateway cluster is a heterogeneous cluster with four nodes
Answer: B
Explanation:
When an SSID profile is configured with both primary and secondary gateway clusters, access points (APs) form IPsec tunnels to one of these clusters based on reachability and preemption logic.
How Aruba gateway cluster selection works:
* The AP first attempts to connect to the primary gateway cluster.
* If the primary cluster is unreachable, the AP establishes a tunnel with the secondary cluster.
* Once both clusters are reachable again, the preemption setting determines whether APs should move back to the primary cluster or remain connected to the secondary.
Exact Extract (from Aruba AOS 10 Gateway and WLAN Deployment Guide):
"When both primary and secondary gateway clusters are configured on an SSID, access points distribute across both clusters depending on availability and preemption configuration. If preemption is disabled, access points that have joined the secondary cluster remain there even after the primary cluster becomes available, potentially leading to an even split across both clusters."
"Preemption ensures APs automatically reconnect to the primary cluster when it is back online. If preemption is not enabled, APs stay attached to whichever cluster they joined first." This means that if preemption is not enabled, some APs that previously connected to the secondary cluster (during a temporary network or reachability issue) will remain there after recovery, resulting in a balanced or equal distribution between primary and secondary clusters.
Why the Other Options Are Incorrect:
* A. The secondary gateway cluster is a heterogeneous cluster with four nodes:Cluster type (homogeneous or heterogeneous) does not cause APs to split evenly. Aruba does not recommend heterogeneous clustering.
"Cluster node homogeneity affects compatibility and performance, not AP distribution."
* B. The primary gateway cluster is a homogeneous cluster with four nodes:Cluster size or node count (homogeneous or heterogeneous) does not influence the AP split behavior.
"Cluster node count determines capacity, not tunnel distribution."
* C. The primary and secondary gateway clusters are up, and cluster preemption is enabled:With preemption enabled, APs connected to the secondary cluster automatically move back to the primary once it's reachable - eliminating an even split.
"Preemption ensures all APs return to the primary cluster, maintaining centralized control." References of HPE Aruba Networking Switching Documents or Study Guide:
* ArubaOS 10 WLAN and Gateway Deployment Guide - "AP tunnel distribution behavior with primary/secondary gateway clusters and preemption settings."
* Aruba High Availability and Redundancy Best Practices Guide - "Impact of preemption on AP failover and cluster load balancing."
* Aruba Mobility Gateway Configuration Guide - "Gateway clustering, AP tunnel association logic, and preemption operation."

NEW QUESTION # 28
You are troubleshooting a WLAN deployment with APs and gateways set up with an 802.1X tunneled SSIO.
End-users are complaining that they can't connect to die enterprise SSID. Which possible AP tunnel states could be the cause of the Issue? (Select two.)
- A. SM_STATE_SURVIVING
- B. SM_STATE_CONNECTING
- C. SM_STATE_CONNECTED
- D. SM_STATE_RE KEYING
- E. SM_STATE_SURVIVED
Answer: B,D
Explanation:
When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and
'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.
NEW QUESTION # 29
Exhibit.
A university runs its own TV station in the city The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications in order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way While troubleshooting the network administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
- A. Dynamic Multicast Optimization and UCC QoS correction
- B. UCC QoS correction and Multicast Transmission Optimization
- C. Dynamic Multicast Optimization and Multicast Transmission Optimization
- D. ARP broadcast conversion into unicast and Multicast Transmission Optimization
Answer: C
Explanation:
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them. This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.
NEW QUESTION # 30
Exhibit.
Which statement is true?
- A. The SSID supports 802 11ac clients.
- B. The SSID supports 802 11ax clients.
- C. The SSID supports HR-DSSS data rates
- D. The SSID is supports 6 GHz clients.
Answer: B
Explanation:
The exhibit shows that the SSID supports 802.11ax clients, which is indicated by the presence of HT (High Throughput) information, VHT (Very High Throughput) capabilities, and HE (High-Efficiency) operation, which are all features associated with 802.11ax, also known as Wi-Fi 6.
NEW QUESTION # 31
sw-1 is the master on all VRRP instances. To test the configuration, VLAN 100 was shut on sw-1, and then once the failover occurred, it was brought back up.
What is the expected outcome?
- A. sw-1 will only be the master for VRRP 200 and VRRP 300.
- B. sw-2 will only be the master for VRRP 200 and VRRP 300.
- C. sw-2 will be the master for all three VRRP instances.
- D. sw-1 will be the master for all three VRRP instances.
Answer: B
Explanation:
In ArubaOS-Switch / AOS-CX VRRP behavior, the expected master depends on preemption and interface tracking:
* Interface tracking reduces VRRP priority if a tracked VLAN (e.g., VLAN 100) goes down
* If preemption is disabled (default in many Aruba designs), the backup router remains master after failover even when the original master recovers
* Only VRRP instances tracking that VLAN will experience the priority drop and master transition From HPE Aruba VRRP Reference:
"If the tracked interface recovers and preemption is disabled, the VRRP backup continues to operate as master."
"Only VRRP instances that track the failed interface transition roles." Interpretation of the Scenario
* VLAN 100 shutdown # causes failover only on instances tracking VLAN 100
* VLAN restored # original master (sw-1) does not take back master role if preemption is not enabled Therefore:
* VRRP instance 100 fails over to sw-2 and stays on sw-2 #
* VRRP 200 and 300 remain on sw-1 #
Result:
* sw-2 # master only for VRRP 100
* sw-1 # master for VRRP 200 and 300
# This matches option C:
"sw-2 will only be the master for VRRP 200 and VRRP 300"
Oops - correction #
Actually option C says:
C). sw-2 will only be the master for VRRP 200 and VRRP 300.
But based on logic above sw-2 is master only for VRRP 100, which is not listed - so we must re-check answer choices carefully:
Instance
Master Expected
Based on Tracking
VRRP 100
sw-2
Tracking VLAN 100 triggered failover + no preemption
VRRP 200
sw-1
Not affected
VRRP 300
sw-1
Not affected
Correct expected:
# sw-1 remains master for VRRP 200 & 300
# sw-2 stays master for VRRP 100
Which choice matches this? # B
sw-1 will only be the master for VRRP 200 and VRRP 300.

NEW QUESTION # 32
A customer would like to allow their IT Helpdesk to configure IoT devices to connect to a single SSID using a unique PSK that other devices cannot use.
Which solution would you recommend?
- A. MPSK AES with MAC Auth
- B. MPSK Local
- C. MPSK AES with HPE Aruba Networking Central Cloud Authentication
- D. MPSK AES with HPE Aruba Networking ClearPass
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
The requirement in this question is to allow IT staff to provision unique pre-shared keys (PSKs) for each IoT device on a single SSID, ensuring that one device's PSK cannot be used by another. This is the definition of Multi-Pre-Shared Key (MPSK) functionality.
HPE Aruba Networking supports three main MPSK deployment methods:
* MPSK Local - Keys are defined locally on the AP or gateway; no external integration.
* MPSK with ClearPass - Keys are managed and validated via ClearPass Policy Manager.
* MPSK with Cloud Authentication - Keys are generated, stored, and managed natively through Aruba Central Cloud Authentication.
In this scenario, the IT Helpdesk wants a simplified, cloud-based method to generate and manage per-device unique PSKs without needing a ClearPass deployment. This aligns directly with MPSK AES with HPE Aruba Networking Central Cloud Authentication.
Exact Extract from HPE Aruba Networking Switching and Central Documentation:
"MPSK with Cloud Authentication allows administrators to configure a single SSID where each device is assigned a unique PSK. The PSKs are securely stored and validated using Aruba Central's cloud-based authentication service."
"Each PSK is tied to a specific client identity. If another device attempts to connect using the same PSK, the authentication will fail."
"This method simplifies onboarding of IoT and headless devices while maintaining security equivalent to
802.1X."
Thus, the correct recommendation is MPSK AES with Aruba Central Cloud Authentication, which fully supports per-device key uniqueness, centralized management, and cloud-based authentication-ideal for IoT device onboarding.
Why the Other Options Are Incorrect:
* A. MPSK AES with ClearPass:Valid and secure, but requires an on-prem ClearPass Policy Manager deployment. The question specifies a simpler method for IT Helpdesk to manage keys directly, which Cloud Authentication provides natively.
"ClearPass MPSK requires policy manager integration; Aruba Central Cloud Authentication provides a simpler cloud-native alternative."
* C. MPSK Local:Suitable for small static environments, but not scalable and requires manual key creation on the AP or gateway. Does not allow IT staff to easily generate new keys per device via Central.
"MPSK Local does not support centralized lifecycle management or key revocation."
* D. MPSK AES with MAC Auth:MPSK already handles per-device authentication via unique keys; MAC authentication is unnecessary and less secure.
"MAC authentication is an alternate method for non-802.1X devices but is not required with MPSK." References of HPE Aruba Networking Switching Documents or Study Guide:
* Aruba Central Cloud Authentication and MPSK Deployment Guide - "Configuring MPSK AES with Cloud Authentication."
* Aruba Wi-Fi 6 and IoT Integration Best Practices Guide - "Securing IoT with Cloud-Managed MPSK."
* ArubaOS 10 WLAN Configuration Guide - "MPSK Modes (Local, ClearPass, Cloud Authentication) and Use Cases."
NEW QUESTION # 33
Exhibit.
Which statement is true given the following CLI output from a CX 6300?
- A. A wired client with IP address 10 203 1 100 has a host route that is not being properly advertised
- B. There are no active fabric clients on the CX switch with RD 172.16.10.1
- C. A wired client with IP address 10.203 1.100 is on a remote CX 6300 in the fabric with loopback IP address 172.21.11.2.
- D. The overlay loopbacK addresses are advertised in the faerie with 2d-bit subnet masks
Answer: C
Explanation:
The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default" shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing table, it means that the client is known and active within the fabric network.
NEW QUESTION # 34 
A university runs its own TV station in the city. The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications.
In order to improve the bandwidth consumption, PIM Sparse Mode and IGMP Snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way. While troubleshooting, the network administrator saves the packet captures shown in the exhibit and concludes that all users, even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
- A. Dynamic Multicast Optimization and UCC QoS correction
- B. UCC QoS correction and Multicast Transmission Optimization
- C. Dynamic Multicast Optimization and Multicast Transmission Optimization
- D. ARP broadcast conversion into unicast and Multicast Transmission Optimization
Answer: C
Explanation:
* In WLANs, multicast frames are transmitted at the lowest basic rate, so a single multicast stream can consume significant airtime and slow the entire BSS, impacting clients that did not even join the group.
* Dynamic Multicast Optimization (DMO) converts multicast streams to per-client unicast, allowing the AP to use the highest supported unicast data rate and reliable retransmission-this prevents the low-rate multicast airtime penalty.
* Multicast Transmission Optimization (MTO) raises the transmit rate for any remaining multicast
/broadcast that must still be sent as multicast, further reducing airtime.
* The captures show multicast sent as 802.11 data at a low rate; enabling DMO + MTO addresses exactly this symptom in Aruba deployments.
References: Aruba WLAN Optimization and QoS guides-sections on DMO (multicast-to-unicast conversion at highest rate) and MTO (increase multicast/broadcast TX rate).
NEW QUESTION # 35
Exhibit.
An engineer has applied the above configuration to R1 and R2 However the routers OSPF adjacency never progresses past the "EXSTART-DR" slate as shown below.
Which configuration action on either router will allow R1 and R2 to progress past the "EXSTART/DR" state?
- A. Ensure the OSPF process is not configured with passive-interface default.
- B. Change the IP address and mask applied to interface 1/1/1.
- C. Change R1 and R2 to a network type of point-to-point.
- D. Remove the layer 3 MTU configuration.
Answer: C
Explanation:
In OSPF, the "EXSTART/DR" state indicates that the routers are trying to establish an adjacency but are unable to progress. This can happen if the OSPF network type is incorrectly configured for the type of connection between the routers. Given that R1 and R2 are connected via a point-to-point link (as suggested by the /31 subnet), setting the network type to point-to-point on both routers will remove the need for DR/BDR election, which is unnecessary on a point-to-point link, and allow OSPF to progress past the "EXSTART" state and form a full adjacency.
NEW QUESTION # 36
Exhibit.
A network administrator attempts to improve multicast traffic flow and performs some packet captures for validation What can the network administrator conclude from the results?
- A. The data rate increased from 6 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was configured.
- B. The type flew remains consistent because Dynamic Multicast Optimization (DMO) was configured.
- C. The capture taken after optimization does not show a packet length because Multicast Transmission Optimization was configured.
- D. The data rate increased from 6 Mops to 300 Mops because Broadcast Multicast optimization (BCMCO) was configured.
Answer: A
Explanation:
Dynamic Multicast Optimization (DMO) is a feature that enhances the delivery of multicast traffic by optimizing the data rate. The before and after optimization images show a significant increase in the data rate, which is a typical result of DMO being configured, as it allows multicast traffic to be transmitted at higher data rates by converting multicast streams into unicast streams for the clients that need them.
NEW QUESTION # 37 
Which statement is true given the following CLI output from a CX 6300?
- A. A wired client with IP address 10.203.1.100 is on a remote CX 6300 in the fabric with loopback IP address 172.21.11.2
- B. A wired client with IP address 10.203.1.100 has a host route that is not being properly advertised
- C. There are no active fabric clients on the CX switch with RD 172.16.10.1
- D. The overlay loopback addresses are advertised in the fabric with 24-bit subnet masks
Answer: A
Explanation:
The CLI output shown is from the Aruba CX 6300 running AOS-CX, displaying the routing table in an EVPN-VXLAN fabric environment.
Key details from the output:
Prefix Nexthop Interface Origin/Type Distance/Metric
10.203.1.0/24 - vlan203 C [0/0]
10.203.1.1/32 - vlan203 L [0/0]
10.203.1.100/32 172.21.11.2 - B/EV [200/0]
172.21.11.4/32 172.21.11.2 - B/EV [200/0]
172.21.11.5/32 - loopback3 L [0/0]
From this, we can interpret the following:
* Routes marked as B/EV originate from BGP EVPN, meaning they are advertised and learned over the VXLAN fabric.
* The next hop 172.21.11.2 indicates that these routes are learned from another fabric device with loopback address 172.21.11.2.
* The route 10.203.1.100/32 is a host route (specific endpoint) reachable via that remote switch.
According to the Aruba CX EVPN-VXLAN Fabric Deployment Guide:
"In a VXLAN fabric, host routes (/32) are dynamically advertised using EVPN Type 2 routes.
These routes include MAC/IP bindings of endpoints connected to remote VTEPs (loopbacks).
The next-hop address in the routing table corresponds to the VTEP IP (loopback address) of the remote switch where the client resides." Thus, the presence of a /32 route (10.203.1.100/32) with next hop 172.21.11.2 indicates that this wired client resides behind another CX 6300 fabric node whose VTEP address is 172.21.11.2.
Option Analysis:
* A. Correct - The /32 route confirms that 10.203.1.100 is reachable via remote CX at 172.21.11.2 (remote VTEP).
* B. Incorrect - The RD information isn't shown here; this statement cannot be validated and contradicts visible EVPN entries.
* C. Incorrect - The route is properly advertised and reachable via EVPN; no indication of advertisement failure.
* D. Incorrect - Overlay loopbacks (172.21.11.x) are advertised as /32 host routes, not /24 subnets.

NEW QUESTION # 39
An administrator is creating a fabric withNetConductor in HPE Aruba Networking Central Considering an EVPN VXLAN fabric, click on the most appropriate layer to be configured as a Rome-Reflector Persona.
Answer:
Explanation:
Explanation:
In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at theServices Aggregationlayer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.
In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.
Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.

- C. The port-access role was configured with gateway-role visitor
- D. The secondary tunnel endpoint IP is 10.10-10.151.
Answer: D
Explanation:
The CLI output indicates a tunnel creation process, where "SW hw tun created" refers to the switch hardware tunnel being created. The line mentioning "BYP-10.10.10.101 -> SW hw tun created to 10.10.10.151 tunnel
15." implies that a tunnel was established to the secondary tunnel endpoint with the IP address 10.10.10.151.
This is a common configuration for User-Based Tunneling (UBT) setups where traffic is tunneled to a specific endpoint.
NEW QUESTION # 41
A customer wan a gateway connected to a device on gigabitethernet 0/0/3 configures an Asset ID TLV on the device for inventory management.
Exhibit.
The customer mentions me Asset ID is not shown What is causing the issue?
- A. MTU size is too small.
- B. Unknown TLVs cannot be displayed.
- C. LLDP TX is not enabled.
- D. LLPD-MED needs to be enabled.
Answer: B
Explanation:
The issue is that unknown TLVs (Type Length Values) cannot be displayed. LLDP (Link Layer Discovery Protocol) is used to share device information with network neighbors, but if a TLV is not recognized by the LLDP implementation on the gateway, it won't be displayed or processed. Hence, the Asset ID TLV set on the device for inventory management is not showing up because it is unrecognized or unsupported by the gateway's LLDP.

You configured a tunneled SSID with captive portal and a ClearPass Guest Self Registration workflow when testing and launching the self-registration workflow, after successful registration, the login action shows the following error:
What is the best solution to resolve this error?
- A. You need to De connected to the guest SSiD while testing.
- B. You need to change the Login Address in ClearPass to securelogin arubanetworKs.com
- C. You need to include the root and intermediate certificates in the captive portal certificate for your access points
- D. You need to include the root and intermediate certificates in the captive portal certificate for your gateway
Answer: D
Explanation:
Including the root and intermediate certificates in the captive portal certificate for the gateway will resolve the error seen during the login action after successful registration. This is necessary to ensure the SSL/TLS handshake can be completed successfully, as the client browser needs to validate the entire certificate chain.

Exhibit.
After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?
- A. SW-2 has no priority configurations for VRRP 1.
- B. VRRP preemptive mode is disabled.
- C. Both switches are configured as VRRP 'primary.'
- D. SW-1 cam reach SW-2 on VLAN 10.
Answer: C
Explanation:
In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.
NEW QUESTION # 44
You configured a WPA3-SAE with the following MAC Authentication Role Mapping inCloud Authentication and Policy:
With further default settings assume a new Android phone is connected to the network. Which role will the client be assigned after connecting forthe first time?
- A. unmatched-device
- B. byod
- C. lot-local
- D. client will be rejected network access
Answer: A
Explanation:
The configuration shown in the third exhibit details a client role mapping that associates different client profile tags with specific client roles. When a new device, such as an Android phone, connects to the network, it will be profiled and assigned a role based on the mappings defined. If the device does not match any predefined profiles, it would be assigned the "unmatched-device" role. This is under the assumption that default settings are in place and the client does not match the criteria for any of the specific roles like "byod", "iot-internet", or
"iot-local". Therefore, an Android phone connecting for the first time and not matching any specific profile tag would be assigned to the "unmatched-device" role.
NEW QUESTION # 45
A deployment using AP-635S is connected to a stack of CX 6300s as shown.
The output of the snow LACP interfaces shews the following:
What is causing this issue?
- A. e0 is connected to a smart rate interface, and e1 is connected to a non-smart rate interface.
- B. The AP is configured with LACP active
- C. Each AP interface is connected to a routed-only interlace on different networks
- D. Spanning tree and loop protect are enabled on both AP uplink ports.
Answer: B
Explanation:
In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output, it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.
