Server administration

Question

A server administrator is creating a design for a new datacenter. The servers should be configured for maximum availability and also provide caching for user information requests. Which of the following techniques should be used?

Options

  • AActive/Passive
  • BRound robin
  • CHeartbeat
  • DActive/Active
  • EPassive/Passive

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.

AActive/Passive

Active/Passive keeps one node idle on standby, so the passive node does not contribute to caching or load distribution during normal operation.

BRound robin

Round robin is a load balancing distribution method, not a server clustering configuration that inherently provides caching or failover.

CHeartbeat

Heartbeat is a monitoring signal exchanged between cluster nodes to detect failures, not a configuration technique for availability or caching.

DActive/ActiveCorrect

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.

EPassive/Passive

Passive/Passive is not a recognized server clustering configuration - having all nodes in standby provides neither availability nor caching.
