CompTIA Linux+ XK0-006 (V8) Practice Question

A system administrator is managing a web application deployed as a replicated service on a Docker Swarm cluster. The service is configured to maintain three replicas for high availability. If a worker node hosting one of these replicas unexpectedly fails and goes offline, what is the primary responsibility of the Swarm manager in response?

  • It will schedule a new task on a healthy node to replace the one on the failed node, thereby restoring the replica count to three.

  • It will wait for the failed node to reconnect to the swarm before taking any corrective action.

  • It will move the existing task from the failed node to a healthy node.

  • It will permanently decrease the service's desired replica count to two to match the new number of healthy replicas.
