You work for a chain of grocery stores. For performance reasons, you want to run each store from
VMs located at the store, but you can only afford one server per store. You want to make sure that
in the event the server fails that the store can run from a VM at the corporate headquarters instead
with minimal downtime. Which solution provides this capability?
A.
High Availability
B.
Data Protection
C.
vSphere Replication
D.
vMotion

Why not high availability (A)? replication and data protection aren’t “minimal downtime”. Although “A” assumes we are using shared storage…so….I don’t know. If we had shared storage, definitely “A”. I think all of the answers assume more about the infrastructure than the question lists. You could use B and C to restore the guest machines on a host at corporate.
My guess on this is that you would use vSphere Replication to (assuming here) use real time or close to real time replication from the store to the corporate office. Then if the server in the store crashed you would have basically a full copy of the machine and data at corporate and could just redirect to it. Using HA technically does work but normally (in my mind) HA is used between servers that are together in the same location and not in two different locations.
