An administrator is upgrading multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters. What two witness node types can the administrator upgrade? (Choose two.)
Correct Answer is A&E
Starting with vSphere 7.0 Update 3, you can use vSphere Lifecycle Manager images to manage a vSAN stretched cluster and its witness host. The following requirements exist:
vCenter Server must be version 7.0 Update 3 and later.
The witness host must be ESXi version 7.0 Update 2 and later.
The witness host must be a virtual server and not a physical server.
The witness host must be a dedicated witness host and not a shared witness host.
A D. To use images, the witness cannot be physical or shared. It must be dedicated or virtual appliance. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere-lifecycle-manager.doc/GUID-F84F1FC8-FBA8-4E4E-845F-40F423CBEEC8.html
A & D are correct

vLCM can monitor and upgrade vSAN stretched and Two-Node clusters. vCLM has the following features for stretched and Two-Node clusters:
• Supports the lifecycle of a witness appliance
• Performs witness node upgrade first, then upgrades the rest of the cluster
• Supports witness node appliances only (physical witness host not supported)
• Supports dedicated witness node, does not support shared witness node

A vSAN Witness Appliance, or a physical host, can be used for the Witness function. The vSAN Witness Appliance includes licensing, while a physical host must be licensed accordingly.

To remediate the witness host against the vSphere Lifecycle Manager cluster image, the following requirements exist:
vCenter Server must be version 7.0 Update 3 and later.
The witness host must be ESXi version 7.0 Update 2 and later.
The witness host must be a virtual server and not a physical server.
The witness host must be a dedicated witness host and not a shared witness host.
