Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 234

What is a function of the IPv6 DHCP Guard feature for DHCP messages?

Answer options

• A. If the device is configured as a DHCP server, no message is switched.
• B. All client messages are always switched regardless of the device role.
• C. It blocks only DHCP request messages.
• D. Only access lists are supported for matching traffic.

Correct answer: B

Explanation

The correct answer is B because the IPv6 DHCP Guard allows all client messages to be switched regardless of whether the device is functioning as a DHCP server or not. Options A, C, and D are incorrect as they misrepresent the behavior of the feature, either limiting the switching capability or incorrectly stating the supported methods for traffic matching.
