ISC2 Certified Cloud Security Professional (CCSP) Practice Question

Your organization hosts customer VMs on a 10-node VMware vSphere cluster that has vSphere High Availability (HA) and Distributed Resource Scheduler (DRS) fully enabled. A critical BIOS update that requires a reboot must be applied to every ESXi host. Contractual SLAs allow no perceptible downtime for the running workloads. Which operational approach will best preserve VM availability while the update is deployed across all hosts?

  • Sequentially place each ESXi server into maintenance mode so DRS evacuates its VMs with live vMotion, patch and reboot the host, then exit maintenance before moving on to the next node.

  • Disable both DRS and HA, then patch all hosts simultaneously to shorten the overall maintenance window.

  • Create strict VM-to-host affinity rules so critical VMs remain on their current hosts during the firmware upgrade.

  • Take snapshots of every VM, power them off, apply the update to all hosts at once, and power the VMs back on after the reboots finish.
