HPE Aruba Certified Network Security Expert (ACNSX) — Question 47

A network engineer is using NetEdit to manage AOS-CX switches. The engineer notices that a lot of third-party VoIP phones are showing up in the NetEdit topology. The engineer deletes these, but they are automatically rediscovered by NetEdit and added back in.
What should the administrator do to solve this problem?

Answer options

• A. Change the VoIP phone SNMP community string to something unknown by NetEdit
• B. Disable LLDP globally on the AOS-CX switches where phones are connected
• C. Disable SSH access on all the VoIP phones
• D. Disable the RESTful API on all the VoIP phones

Correct answer: A

Explanation

Changing the SNMP community string to an unknown value prevents NetEdit from recognizing and rediscovering the VoIP phones, which resolves the issue. Disabling LLDP (option B) would stop the switches from discovering devices but may affect other necessary functionalities. Disabling SSH (option C) or the RESTful API (option D) on the VoIP phones would not prevent their discovery by NetEdit and is not relevant to the issue at hand.
