Implementing Cisco Collaboration Devices (CICD, legacy) — Question 102

With GETVPN, if a key server is configured to use multicast as the rekey transport mechanism, then under which of these conditions will the key server retransmit the rekey messages?

Answer options

• A. It never retransmit the rekey messages.
• B. It only retransmit the rekey message when it does not receive the rekey acknowledgment from at least one group member.
• C. It only retransmit the rekey message when it does not receive the rekey acknowledgment from all group member.
• D. It only retransmit the rekey message when DPD to the group members fails.
• E. It always retransmit the rekey message.

Correct answer: E

Explanation

The correct answer is E because the key server is designed to ensure all group members receive the rekey messages, hence it will always retransmit them. Options A, B, C, and D incorrectly limit the conditions under which retransmission occurs, suggesting that acknowledgment or failure to reach certain members impacts retransmission, which is not the case.
