Configuring High Availability for File Gateway

Question

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?

A. B. C. D.

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.

The correct answer is B. A shared datastore.

To enable the High Availability (HA) feature of the file gateway in an on-premises VMware vSphere cluster, an additional prerequisite is necessary: a shared datastore. A shared datastore is required because the file gateway is deployed as a virtual machine (VM) in the VMware vSphere cluster, and for the HA feature to work, the VM must be able to access the same data and configuration files from any host in the cluster. This can be achieved by storing the data and configuration files on a shared datastore that is accessible by all hosts in the cluster.

Option A, Multiple S3 buckets in a single AZ, is not relevant to the HA feature of the file gateway. It is related to data availability and durability within an AWS Availability Zone (AZ).

Option C, Multiple S3 buckets in different AZ, is also not relevant to the HA feature of the file gateway. It is related to data availability and durability across different AWS AZs.

Option D, Cluster with vSphere DRS mode enabled, is not a prerequisite for the HA feature of the file gateway. vSphere Distributed Resource Scheduler (DRS) is a feature that automatically balances the workload across hosts in a VMware vSphere cluster based on resource utilization. While DRS can help improve resource utilization and performance, it is not necessary for the HA feature of the file gateway.
