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

Explanation:
Introducing Read-only Access to Geo Redundant Storage (RA-GRS):
RA-GRS allows you to have higher read availability for your storage account by providing “read
only” access to the data replicated to the secondary location. Once you enable this feature, the
secondary location may be used to achieve higher availability in the event the data is not available
in the primary region. This is an “opt-in” feature which requires the storage account be georeplicated.
