An IT company has deployed a file gateway as a VM in an on-premises HA-enabled VMware vSphere cluster. To provide redundancy, this file gateway needs to be configured as HA and will be used to upload data to the Amazon S3 bucket.
What is an additional prerequisite necessary for using the HA feature of file Gateway? 

Answer options:

A.Multiple S3 buckets in a single AZ.
B.A shared datastore.
C.Multiple S3 buckets in different AZ.
D.Cluster with vSphere DRS mode enabled.

Correct Answer: B
To use the HA feature of Storage Gateway, the VMware environment must provide the following:
A cluster with vSphere HA enabled
A shared datastore
Option A is incorrect as Multiple S3 buckets in a single AZ are not a prerequisite for using the HA feature of file gateway within a VMware environment.
Option C is incorrect as S3 bucket in different AZ is not a prerequisite for using the HA feature of file gateway within a VMware environment.
Option D is incorrect as vSphere DRS mode is for load-balancing; it`s not required for using the HA feature of file gateway within a VMware environment.
