Implementing DevOps Solutions and Practices Using Cisco Platforms (DEVOPS) — Question 31

A developer wants to deploy a highly available web server cluster and decides to put a load balancer in front of multiple clustered nodes that run the same web service. The goal is for the load balancer to take in users and distribute the load across the whole cluster.
What kind of high-availability configuration is the developer running?

Answer options

• A. active
• B. passive
• C. active-passive
• D. active-active

Correct answer: C

Explanation

The correct answer is C, active-passive, as it describes a configuration where some nodes are actively handling traffic while others are on standby, ready to take over if needed. In contrast, active and active-active configurations involve all nodes being active at the same time, which is not the case here, and passive implies no active nodes are handling requests.
