Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 570

Which feature drops packets if the source address is not found in the snooping table?

Answer options

• A. IPv6 Destination Guard
• B. IPv6 Source Guard
• C. Binding Table Recovery
• D. IPv6 Prefix Guard

Correct answer: B

Explanation

The correct answer is IPv6 Source Guard, as it is specifically designed to prevent packets from being sent if the source address is not present in the snooping table. The other options do not have the same functionality: IPv6 Destination Guard focuses on destination addresses, Binding Table Recovery deals with restoring bindings, and IPv6 Prefix Guard is related to prefix filtering.
