NEW QUESTION # 65
You are reviewing the configuration of an aggregation switch and have noticed that VLAN 1 is configured as the native VLAN on all interfaces connected to access switches. Why might this have been configured?
- A. To support LLDP
- B. To support UBT
- C. To support MSTP
- D. To support ZTP
Answer: D
Explanation:
Comprehensive Detailed Explanation:
VLAN 1 is often configured as the native VLAN on interfaces to support Zero Touch Provisioning (ZTP).
During ZTP, devices communicate over VLAN 1 by default to download their configuration and updates.
LLDP and UBT are unrelated to native VLAN configuration for provisioning.
MSTP relates to spanning tree but does not dictate native VLAN usage.
Thus, VLAN 1 as native VLAN facilitates ZTP processes.

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. HTTPS client certificate
- C. Trust Anchor profile
- D. User-role configuration
Answer: C
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.
