Question

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?

Options

  • Aactive
  • Bpassive
  • Cactive-passive
  • Dactive-active

Why each option

The question describes a high-availability setup with a load balancer distributing traffic among multiple active web server nodes.

Aactive

"Active" alone is insufficient to describe a multi-node cluster with load balancing; it implies one active component without specifying the redundancy model.

Bpassive

A passive configuration typically involves a backup node that only becomes active if the primary node fails, without sharing the load.

Cactive-passive

Active-passive involves one primary active node and one or more standby passive nodes that take over upon failure, which is different from distributing load across all nodes.

Dactive-activeCorrect

An active-active high-availability configuration involves multiple nodes simultaneously processing requests, with a load balancer distributing the workload across all active instances. This setup maximizes resource utilization and provides redundancy as traffic can be distributed even if one node fails.
