NEW QUESTION # 82
Examine the following AOS-CX configuration:
Based on this configuration, which statement is correct regarding IoT traffic?
- A. The next hop of 10.100.1.2 can be one or more hops away from the AOS-CX switch
- B. If 10.100.1.2 is not reachable, the IoT traffic will be automatically dropped by the switch
- C. All routes are ignored in the routing table for IoT traffic, which is routed to 10.100.1.2

- A. clear qos setting
- B. delete qos profile
- C. unset qos policy

NEW QUESTION # 85
How would the route type affect the configuration if an OSPF configuration has several external routers?
- A. If you have a primary exit with a secondary backup, you must choose E1, the primary with a lower default metric than the secondary.
- B. If you want to consider internal and external costs equally, use E2 routes.
- C. If you want to leverage all paths to destinations, use E2 with the same default metric.
- D. If you want to use the closet exit point, use E2 with appropriate seed metric.
Answer: A
Explanation:
OSPF E1 external routes include both the external cost and the internal OSPF cost to reach the ASBR, allowing selection of a primary exit with a lower metric while keeping a secondary backup, ensuring predictable path selection.
NEW QUESTION # 86
You are reviewing the configuration of a VSX lag and have noticed the command lacp fallback.
Why might this have been configured?
- A. For backwards compatibility with LACP v1.
- B. To support provisioning a switch without LACP.
- C. To allow operation with active or passive LACP.
- D. For operation using a single partner LACP interface.
Answer: D
Explanation:
The lacp fallback command allows a VSX LAG to operate even if only a single LACP partner interface is active, ensuring connectivity when other links in the LAG are down or unavailable.
NEW QUESTION # 87

Explanation:
The show port-security and show mac-address-table secure commands display secured MAC addresses, helping administrators enforce network access policies.
NEW QUESTION # 88
Which CLI command displays all currently active ARP entries on an Aruba CX switch?
- A. display arp
- B. show interfaces arp
- C. show ip arp
- D. show arp table
Answer: C

NEW QUESTION # 94
You are implementing a design where the campus network should be in an isolated spanning tree topology from the data centre network. The core switches are connected by a single Layer-2 interface carrying multiple VLANs.
When you examine the switches, you discover that the campus core sees the data centre core as the root bridge.
What configuration can you apply to the campus-to-data centre core link to resolve the issue?
- A. BPDU filter
- B. Admin edge
- C. BPDU guard
- D. Root guard
Answer: D
NEW QUESTION # 95

- B. display stp status
- C. show spanning-tree bpdu-guard
- D. show bpdu block
Answer: C
Explanation:
The show spanning-tree bpdu-guard command reveals ports disabled due to BPDU violations, helping prevent unauthorized devices from injecting spanning-tree loops.
NEW QUESTION # 96
Refer to the output:
Which CLI command was used to produce this output?
- A. Use show checkpoint compare to compare running-config with stored saved-config revisions.
- B. Use show checkpoint diff to compare running-config with stored checkpoints.
- C. Use checkpoint compare to compare running-config with stored saved-config revisions.
- D. Use checkpoint diff to compare running-config with stored checkpoints.
Answer: B
Explanation:
The output shows a unified diff-style comparison with added and removed configuration lines, which is generated by the command that performs a diff between the running configuration and a stored checkpoint. The ArubaOS-CX syntax that produces this format is the show checkpoint diff command.
NEW QUESTION # 97
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: C
Explanation:
A multihomed Internet-facing BGP deployment requires a globally unique public autonomous system number. The value 63476 is within the public ASN range allocated for use on the Internet, making it suitable for advertising your own public IP space to multiple ISPs.
NEW QUESTION # 98
Which two CLI commands display the status of all switch interfaces? (Select two)
- A. show vlan
- B. show interfaces brief
- C. show interface status
- D. show ip route
Answer: B,C

NEW QUESTION # 99
An administrator is managing a network comprised of AOS-CX switches deployed at the aggregation layer. The switches are paired in a VSX stack and run the OSPF routing protocol.
The administrator is concerned about how long it takes for OSPF to converge when one of the VSX switches has to reboot.
What should the administrator to do speed up the OSPF convergence of the switch that is rebooting?
- A. Change the VSX ISL link from an OSPF broadcast link point-to-point.
- B. Implement graceful restart on the VSX switches and their neighboring OSPF switches.
- C. Define non-backbone areas on the VSX switches as totally stubby areas.
- D. Decrease the VSX initial synchronization timer on the two VSX switches.
Answer: B
NEW QUESTION # 100
You have added a switch with existing configuration to an existing group in HPE Aruba Networking Central but the configuration is not synchronizing. What could cause this?
- A. The switch is configured in a VSX pair, which HPE Aruba Networking Central does not support.
- B. The switch is still pending authorization on the organization settings page.
- C. Only switches with factory default config can be added to a group with existing config.
- D. The switch cannot establish a management connection with HPE Aruba Networking Central.
Answer: C
Explanation:
This scenario highlights the " Source of Truth " logic within Aruba Central UI Groups .
* UI Group Constraints: When a group is managed via the UI (User Interface) mode , Central acts as the absolute master of the configuration. If you add a switch that already has a local configuration (non- factory default) into a group that already has an established configuration, Central perceives a Configuration Conflict .
* The Safety Mechanism: To prevent Central from accidentally wiping out a production switch ' s settings the moment it connects, Central will not automatically synchronize (push) the group configuration to a device that is not in a Factory Default state.
* The Resolution: For the switch to synchronize with an existing UI group, you must either:
* Erase the startup-configuration on the switch and reboot it (Factory Default), allowing it to " pull " the group config cleanly.
* Manually resolve the conflict by moving the device into the group and then selecting the option to overwrite the local configuration with the group configuration.
* Evaluating Other Options:
* Option A: This is false. Central fully supports VSX monitoring and configuration (specifically via Template groups or the VSX orchestration UI).
* Option B: If the switch is " added to a group, " it has already passed the initial onboarding
/authorization phase.
* Option C: If it " cannot establish a connection, " the switch would show as Offline , not as a synchronization failure within a group.
NEW QUESTION # 101
You are troubleshooting a performance issue with a VSX LAG and have run the following troubleshooting commands:
show run int 1/1/11
show run int 1/1/11 vsx-peer
Which troubleshooting methodology does this exemplify?
- A. Replace configuration
- B. Top-down/Bottom-up
- C. Follow the path
- D. Spot the difference
Answer: D
Explanation:
Comparing the interface configuration on the local switch with the VSX peer's configuration exemplifies the "spot the difference" methodology, helping identify discrepancies that may cause LAG performance issues.
