A. IPv6 Router Advertisement Guard: Correct: IPv6 Router Advertisement (RA) Guard is designed to prevent rogue or unauthorized Router Advertisements from being processed by hosts on the network. This helps to protect against DoS attacks where malicious devices might send incorrect RA messages, causing network disruption. By filtering and controlling RA messages, IPv6 RA Guard helps prevent such attacks.

B is correct

IPv6 - Destination Guard The Destination Guard feature helps in minimizing denial-of-service (DoS) attacks. It performs address resolutions only for those addresses that are active on the link, and requires the FHS binding table to be populated with the help of the IPv6 snooping feature. The feature enables the filtering of IPv6 traffic based on the destination address, and blocks the NDP resolution for destination addresses that are not found in the binding table. By default, the policy drops traffic coming for an unknown destination.
