NEW QUESTION # 14
An administrator is defining a VSX LAG on a pair of AOS-CX switches that are defined as primary and secondary. The VSX LAG fails to establish successfully with a remote switch; however, after verification, the remote switch is configured correctly. The administrator narrows down the problem to the configuration on the AOS-CX switches.
What would cause this problem?
- A. Local optimization was not enabled on the VSX LAG
- B. The VSX LAG hash does not match the remote peer
- C. The VSX LAG interfaces are in layer-3 mode
- D. LACP was enabled in active mode on the VSX LAG
Answer: C
Explanation:
VSX LAG are not supported at Layer 3.
VSX LAG does support all the standard LAG adjustments: timers, L2 or L3 hashing, LACP fallback.
It supports both LACP mode active or static mode, and only Layer 2 (i.e. no routed mode).

NEW QUESTION # 19
How do HPE Aruba Networking CX VSX solutions make the hardware replacement of a single switch a non-disruptive operation for L3 configurations??
- A. By utilizing any of the 16 different vMAC addresses with active gateway.
- B. By the VSX-sync option for synchronization of the system-MAC.
- C. By allowing changes to the system-MAC in the ServiceOS with the original system MAC.
- D. By replicating the primary VSX's default system-AC to the secondary switch.
Answer: B
Explanation:
The VSX-sync feature synchronizes the system MAC between the primary and secondary VSX switches, ensuring that L3 configurations remain valid and uninterrupted during a single switch replacement.
NEW QUESTION # 20
Which two Aruba CX switch features are essential for securing and segmenting user traffic? (Select two)
- A. Intelligent Power Management
- B. Dynamic Segmentation
- C. EVPN/VXLAN
- D. VSF (Virtual Switching Framework)
Answer: B,C
Explanation:
Dynamic Segmentation integrates with ClearPass for policy-based VLAN enforcement, while EVPN/VXLAN allows scalable network segmentation across Layer 2 and Layer 3 domains.
NEW QUESTION # 21
You are helping another engineer troubleshoot a new downloadable user role configuration between your CX switches and ClearPass.
Which configuration on the switch should you verify?
- A. SNMP community string
- B. Trust Anchor profile
- C. HTTPS client certificate
- D. User-role configuration
Answer: B
Explanation:
When troubleshooting downloadable user roles (DUR) between Aruba CX switches and ClearPass, it is crucial to verify the Trust Anchor profile on the switch. The Trust Anchor profile contains the certificates and keys that allow secure communication and authentication with ClearPass, ensuring the switch can validate the RADIUS server and downloaded user role information.
SNMP community string (Option A) is unrelated to DUR.
User-role configuration (Option B) is important but verifying trust anchor ensures secure role downloads.
HTTPS client certificate (Option C) is not typically part of DUR authentication.
Therefore, the Trust Anchor profile must be verified.

NEW QUESTION # 22
Your company needs to run BGP in a multi-homed configuration to two ISPs, advertising a block of public address space you own. Which AS number would be an example of a suitable number?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
A publicly routable, globally unique autonomous system number is required when advertising your own address space to multiple ISPs. The value 63479 falls within the public AS number range assigned by IANA and can be used for Internet-facing BGP peering.
NEW QUESTION # 23
In an attempt to clear the switch configuration, you've issued the command erase all zeroize.
What is the result of this task?
- A. The switch runs a secure erase task, deleting the startup-config, and retains admin credential password.
- B. The switch restores the factory-installed AOS-CX image to the switch.
- C. The switch runs a secure erase task, deleting all customer data, and may run up to an hour.
- D. The switch clears all user credentials and retains the running configuration.
Answer: C
Explanation:
The erase all zeroized command performs a secure erase of all customer data on the switch, ensuring complete data removal; this process can take up to an hour to complete.
NEW QUESTION # 24
You are configuring a new switch using device profiles and the same configuration across all non- uplink interfaces. You are connected that the switch may not have enough PoE budget to power all devices that will eventually be connected. How can you guarantee that APs will always receive power over other devices?
- A. Enable the LLDP MED Power (PoE) TLV.
- B. Configure QoS trust PoE on each interface.
- C. Configure critical PoE priority in the AP role.
- D. Configure always-on PoE in the AP VLAN.
Answer: C
Explanation:
Assigning a critical PoE priority to the AP role ensures that access points receive power before other devices when the PoE budget is insufficient, guaranteeing continuous operation.
