HPE Aruba Certified Professional (ACP) – SD-WAN — Question 75

Your customer is concerned about users connecting unmanaged switches to the network and causing outages. Which CX switch feature should you recommend?

Answer options

• A. Port security
• B. BPDU Guard
• C. Loop protection
• D. MAC authentication

Correct answer: B

Explanation

The correct choice is BPDU Guard, as it prevents loops by blocking BPDUs from being received on ports where they are not expected, thus protecting the network from outages caused by unmanaged switches. Port security, loop protection, and MAC authentication do not specifically address the issue of preventing BPDUs from unauthorized devices, making them less effective in this scenario.
