Which two considerations should an architect assess when designing a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA)? (Choose two.)

Correct Answer:CE
To design a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA), two considerations that the architect should assess are: A minimum of three nodes are required within the client cluster for vSphere HA to work. This is because vSphere HA needs at least three nodes in a cluster to form a quorum and elect a master host that monitors the availability of other hosts and VMs. If there are less than three nodes in a cluster, vSphere HA cannot function properly and might fail to detect or respond to host or VM failures. If vSphere HA is to work with HCI Mesh, Datastore with All Paths Down (APD) must be configured to Power off and restart VMs. This is because APD is a condition that occurs when a storage device becomes inaccessible due to loss of physical connectivity, resulting in I/O errors or timeouts for VMs that use that device. When using HCI Mesh, APD can happen if the network connection between the client cluster and the server cluster is lost or disrupted, causing the remote datastore to become unavailable. To ensure that vSphere HA can restart the affected VMs on another host that has access to their storage, Datastore with APD must be set to Power off and restart VMs in the vSphere HA settings. The other options are not correct. A server vSAN cluster can serve its local datastore up to 15 client vSAN clusters, not five. This is the maximum number of client clusters that can mount a remote datastore from a server cluster using HCI Mesh. A client cluster can mount up to five remote datastores from one or more vSAN server clusters, not ten. This is the maximum number of remote datastores that can be mounted by a client cluster using HCI Mesh. References: VMware vSAN HCI Mesh; vSphere Availability; Handling All Paths Down (APD) Conditions
