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 geo-replicated.

wrong should be B.
does not state in the question if you are doing real time analytics which is what RA-GRS is. Also RA-GRS requires a manual failover.

Given answer is correct… it makes it highly available and gives read access in the event of a site outage.

No, should be RA-GRS
Think about this:
If one or more Storage services are temporarily unavailable at one or more regions, there are two options for you to consider.
Options 1. Wait for service back, you can’t do anything and the Data is NOT readable in secondary region if using GRS.
Option 2: Copy data from secondary
If you chose Read-access geo-redundant storage (RA-GRS) (recommended) for your storage accounts, you will have read access to your data from the secondary region. You can use tools such as AzCopy, Azure PowerShell, and the Azure Data Movement library to copy data from the secondary region into another storage account in an unimpacted region, and then point your applications to that storage account for both read and write availability
If you desire immediate access to your data, please consider Option 2.
And RS-GRS is recommended by Microsoft even it’s little expensive than GRS.
