Which storage option should you enable?

Your company network has two physical locations configured in a geo-clustered environment.

You create a Blob storage account in Azure that contains all the data associated with your company.

You need to ensure that the data remains available in the event of a site outage.

Which storage option should you enable?
A . Locally redundant storage
B . Geo-redundant storage
C . Zone-redundant storage
D . Read-only geo-redundant storage

Answer: D

Explanation:

Read-access geo-redundant storage (RA-GRS) maximizes availability for your storage account, by providing read-only access to the data in the secondary location, in addition to the replication across two regions provided by GRS.

When you enable read-only access to your data in the secondary region, your data is available on a secondary endpoint, in addition to the primary endpoint for your storage account.
