CompTIA Server+ SK0-005 Practice Question
Your organization operates a three-node failover cluster that provides a highly available file service. During the next maintenance window you must install critical OS security updates without breaching the SLA, which allows only brief failovers but no prolonged service interruption. According to recommended proper patching procedures for clustered servers, which approach should you take?
Evict every node from the cluster, apply patches while the cluster is offline, and recreate the cluster once all nodes are updated.
Disable the cluster heartbeat on all nodes, install the patches on every node simultaneously, then re-enable the heartbeat after all servers restart.
Patch the passive nodes now but delay patching the active node until the next window to avoid any failover events.
Pause (drain) one node, move its clustered roles to other nodes, patch and reboot the node, resume it, then repeat for the remaining nodes.
