Which two considerations should an architect assess when designing a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA)? (Choose two.)
A.
A server vSAN cluster can serve its local datastore up to five client vSAN clusters.
B.
A client cluster can mount up to ten remote datastores from one or more vSAN server clusters.
C.
A minimum of three nodes are required within the client cluster for vSphere HA to work.
D.
If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be configured to Power off and restart VMs.
E.
If vSphere HA is to work with HCI Mesh, Datastore with All Paths Down (APD) must be configured to Power off and restart VMs.
I would say, A&B are correct, the question is around design considerations only, not on the functionality
see below
HCI Mesh Design Considerations
A number of other design criteria should be considered when configuring vSAN HCI Mesh.
HCI Mesh Limits
Client cluster: Can mount up to a maximum of 5 remote vSAN datastores
Server cluster: Can only serve its datastore to a maximum of 10 client clusters - as of vSAN 8. Previous versions supported the mounting of up to 5 client clusters.
The correct answer is C & E :
C : HCI Mesh is not supported on 2-Node clusters. That means you must have at least a 3 nodes cluster. This is more globally a minimum required for vSAN Clusters with HA enabled. --> https://docs.vmware.com/en/VMware-vSphere/8.0/vsan-planning/GUID-D68890D8-841A-4BD1-ACA1-DA3D25B6A37A.html and https://core.vmware.com/resource/vmware-vsan-hci-mesh#sec10709-sub2
E : when using HCI Mesh, the client cluster must have the APD configured on vSphere HA to be able to manage the VMs when the remote datastore is lost. --> https://core.vmware.com/resource/vmware-vsan-hci-mesh#sec10706-sub1
A & B are wrong. This is the contrary : A server cluster can serve up to 10 client clusters in vSAN 8 (was limited to 5 in vSAN 7), and a client cluster can connect to up to 5 server clusters --> https://core.vmware.com/resource/vmware-vsan-hci-mesh#sec10706-sub3
D: wrong. It is not necessary and even useless. The loss of a device is managed by the server cluster
a - true
b - True
