The correct answer is D. Active/Active. Active/Active clustering keeps all nodes simultaneously processing requests, which provides both high availability and the ability to cache user information across nodes.

Why each option
Active/Active clustering keeps all nodes simultaneously processing requests, which provides both high availability and the ability to cache user information across nodes.
Active/Passive keeps one node idle on standby, so the passive node does not contribute to caching or load distribution during normal operation.
Round robin is a load balancing distribution method, not a server clustering configuration that inherently provides caching or failover.
Heartbeat is a monitoring signal exchanged between cluster nodes to detect failures, not a configuration technique for availability or caching.
In an Active/Active configuration, all nodes are online and handling traffic at the same time, meaning if one node fails the others continue without interruption - satisfying maximum availability. Because each node is actively serving requests, session and user information can be cached across the cluster, addressing the caching requirement directly.
Passive/Passive is not a recognized server clustering configuration - having all nodes in standby provides neither availability nor caching.
