An administrator has a requirement to revert a running virtual machine to a previous snapshot after a failed attempt to upgrade an application. When the administrator originally took the snapshot the following choices in the Take Snapshot dialog were made:
Snapshot the virtual machine’s memory = false 
Quiesce guest file system = false
What will be the result of the administrator selecting the ‘Revert to Latest Snapshot? option to return the virtual machine to a previous snapshot?
Correct Answer:
B
Powered on (does not include memory) Reverts to the parent snapshot and the virtual machine is powered off. Powered off (does not include memory) Reverts to the parent snapshot and the virtual machine is powered off. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-vm-administration/GUID-50BD0E64-75A6-4164-B
An administrator is attempting to configure Storage I/O Control (SIOC) on five datastores within a vSphere environment. The administrator is being asked to determine why SIOC configuration completed successfully on only four of the datastores.
What are two possible reasons why the configuration was not successful? (Choose two.)
Correct Answer:
AC
SIOC configuration may fail if the datastore contains RDMs or has multiple extents, as these are not supported by SIOC.

Storage I/O Control is supported on Fibre Channel-connected, iSCSI-connected, and NFS-connected storage. Raw Device Mapping (RDM) is not supported. Storage I/O Control does not support datastores with multiple extents.
Which four elements can a vSphere Lifecycle Manager image contain? (Choose four.)
Correct Answer:
ADFG
https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-lifecycle-manager/GUID-9A20C2DA-F45F-4C9B-9 A vSphere Lifecycle Manager image can consist of the following four elements:
ESXi base image
The base image contains an image of VMware ESXi Server and additional components, such as drivers and adapters that are necessary to boot a server. The base image is the only mandatory element in a vSphere Lifecycle Manager image. All other elements are optional.
Vendor add-on
The vendor add-on is a collection of software components that OEMs create and distribute. The vendor add-on can contain drivers, patches, and solutions.
Firmware and drivers add-on
The firmware and drivers add-on is a special type of vendor add-on designed to assist in the firmware update process. The firmware and drivers add-on contains firmware for a specific server type and corresponding drivers. To add a firmware and drivers add-on to your image, you must install the hardware support manager plug-in provided by the hardware vendor for the hosts in the respective cluster.
Independent components
The component is the smallest discrete unit in an image. The independent components that you add to an image contain third-party software, for example drivers or adapters.
An administrator needs to provide encryption for workloads within an existing vSphere cluster. The following requirements must be met:
• Workloads should be encrypted at rest.
• Encrypted workloads must automatically be encrypted during transit.
• Encryption should not require any specific hardware.
What should the administrator configure to meet these requirements?
Correct Answer:
D
The feature that should be configured to provide encryption for workloads within an existing vSphere cluster without requiring any specific hardware is VM Encryption, which allows encrypting VMs at rest and during vMotion.
