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?
A . active
B. passive
C. active-passive
D. active-active
Answer: D
Explanation:
An active-active high-availability configuration is when the load balancer is used to distribute the load across the whole cluster of nodes that are running the same web service. In this configuration, all of the nodes are active and available to serve requests at any given time. This is in contrast to an active-passive configuration, where only one node is active and the other nodes are passive and serve as backups in case of a failure.
