NEW QUESTION # 24
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?
- A. Enable vSphere High Availability (HA) admission control and set the VM power state to the suspend to memory option
- B. Enable Quick Boot and set the VM power state to the suspend to disk option
- C. Enable Quick Boot and set the VM power state to the suspend to memory option
- D. Enable Distributed Power Management (DPM) and set the VM power state to the suspend to disk option
Answer: C
Explanation:
Explanation
https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-lifecycle-manager/GUID-06A5D316-9452-4A5D-A5 The administrator should enable Quick Boot and set the VM power state to the suspend to memory option, which will allow the administrator to reduce the downtime associated with the patching operation without migrating the VMs. Quick Boot is a feature that skips the hardware initialization phase during host reboot, which reduces the system boot time. Suspend to memory is an option that preserves the state of the VMs in the host memory and restores them from memory after the reboot, which minimizes the VM downtime. These two features work together to optimize the remediation process and speed up the patching operation. References:

Run a hardware compatibility check using vSphere Lifecycle Manager, which verifies that the new software and firmware versions are compatible with the vSAN Hardware Compatibility List.
NEW QUESTION # 31
An administrator is responsible for performing maintenance tasks on a vSphere cluster. The cluster has the following configuration:
. Identically configured vSphere ESXi hosts (esx01, esx02, esx03 and esx04)
* All workloads are deployed into a single VMFS datastore provided by the external storage array
* vSphere High Availability (HA) has not been enabled
* vSphere Distributed Resource Scheduler (DRS) has not been enabled
Currently, a critical production application workload (VM1) is running on esx01.
Given this scenario, which two actions are required to ensure VM1 continues to run when esx01 is placed into maintenance mode? (Choose two.)
- A. VM1 must be manually shut down and cold migrated to another host within the cluster using vSphere vMotion before esx01 is placed into maintenance mode.
- B. VM1 must be manually migrated to another host within the cluster using vSphere Storage vMotion before esx01 is placed into maintenance mode.
- C. VM1 must be manually live migrated to another host within the cluster using vSphere vMotion before esx01 is placed into maintenance mode.
- D. vSphere HA must be enabled on the cluster so that VM1 will be automatically migrated to another host within the cluster when esx01 is placed into maintenance mode.
- E. Fully automated DRS must be enabled on the cluster so that VM1 will be automatically migrated to another host within the cluster when esx01 is placed into maintenance mode.
Answer: C,E
Explanation:
Two actions that are required to ensure VM1 continues to run when esx01 is placed into maintenance mode are enabling fully automated DRS on the cluster, which allows balancing the workload across hosts and migrating VMs without user intervention; and manually live migrating VM1 to another host within the cluster using vSphere vMotion, which allows moving a running VM without downtime.
