Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 250

What is a characteristic of IPv6 RA Guard?

Answer options

• A. It filters rogue RA broadcasts from connected hosts.
• B. It is supported on the egress direction of the switch.
• C. RA messages are allowed from the host port to the switch.
• D. It is unable to protect tunneled traffic.

Correct answer: D

Explanation

The correct answer is D because IPv6 RA Guard is designed to protect against rogue Router Advertisements but does not provide security for traffic that is tunneled. Options A, B, and C incorrectly describe the functionality of RA Guard, as they misrepresent its purpose or limitations.
