An administrator is tasked with creating a two-node VMware vSAN cluster for a remote branch...

In a two-node vSAN cluster , a third component called a witness host is required to provide quorum and prevent split-brain scenarios. The VMware vSAN documentation states:

“A two-node vSAN cluster requires a witness host to maintain cluster quorum. The witness can be either a dedicated physical ESXi host or a vSAN Witness Appliance deployed as a virtual appliance.”

Valid witness options:

Physical ESXi Host (A) – A dedicated host that participates only as a witness and does not store data.

vSAN Witness Appliance (B) – A preconfigured virtual appliance provided by VMware that runs ESXi and serves as the witness host.

Incorrect options:

VCF Operations appliance (C) is for monitoring and analytics.

VCF Installer (D) is used for deployment workflows.

vCenter appliance (E) manages the cluster but does not act as a witness.

Therefore, the two correct options are Physical ESX Host and vSAN Witness Appliance .
