Designing Cisco Data Center Infrastructure (DCID) — Question 110

An engineer is designing a disaster recovery solution. In the event of a node failure, the solution should either direct all of the traffic to another node, or load-balance the traffic across the remaining nodes.

Which solution should be implemented in the design?

Answer options

• A. active/active
• B. cold standby
• C. active/passive
• D. warm standby

Correct answer: A

Explanation

The active/active configuration allows multiple nodes to handle traffic simultaneously, ensuring that if one node fails, the others can take over without interruption. In contrast, cold standby does not provide immediate failover, and active/passive only allows one node to handle traffic while the other remains idle, making them unsuitable for this scenario. Warm standby offers limited support but is not as effective as active/active for load balancing traffic.
