A vSphere administrator needs to add more space to an existing 3-node Virtual SAN
cluster. The attempts to add the new host to the cluster as a contributing member have
failed. However, it can be added as a non-contributing member. The host was previously
used in a single host configuration. The administrator recently upgraded the host from ESXi
5.1 to 5.5 prior to adding it to the cluster. What is the reason for this failure?

A.
The RAID controller in the new host does not have enough cache for the Virtual SAN
datastore.

B.
The new host’s VMFS datastores do not have sufficient capacity to be added as a
contributing member.

C.
The only SSD disk in the new host was formatted with a VMFS datastore.

D.
The new host has a 10Gbps NIC while the rest of the cluster members have 1Gbps

NICs.
