VMware vSphere 8.x Professional — Question 64

An administrator is configuring vSphere Lifecycle Manager to install patches to a vSphere cluster. The cluster runs workload virtual machines (VMs) that are incompatible with vSphere vMotion, and therefore cannot be live migrated between hosts during the installation of the patches.
Which configuration in vSphere Lifecycle Manager will allow the administrator to reduce the downtime associated with the patching operation without migrating the VMs?

Answer options

• A. Enable Distributed Power Management (DPM) and set the VM power state to the suspend to disk option
• B. Enable Quick Boot ana set the VM power stale to the suspend to disk option
• C. Enable vSphere High Availability (HA) admission control and set the VM power stale to the suspend to memory option
• D. Enable Quick Boot and set the VM power state to the suspend to memory option

Correct answer: D

Explanation

The correct answer is D because enabling Quick Boot allows the host to reboot quickly while preserving the state of VMs, and suspending to memory keeps the VM's state in RAM for fast recovery. Options A and B do not utilize the benefits of Quick Boot effectively as they suggest suspending to disk, which increases downtime. Option C does not directly address the need for reducing downtime during patching.
