A company wants to ensure their storage account data is replicated to a secondary geographic region hundreds of miles away to protect against a regional disaster. Which redundancy option should they choose?
Answer options:
A.
Locally redundant storage (LRS)
B.
Zone-redundant storage (ZRS)
C.
Geo-redundant storage (GRS)
D.
Premium block blobs
How to approach this question
Match the requirement 'secondary geographic region' to the correct redundancy acronym.
Full Answer
C.Geo-redundant storage (GRS)✓ Correct
Geo-redundant storage (GRS)
Geo-redundant storage (GRS) copies your data synchronously three times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a single physical location in a secondary region.
Common mistakes
Choosing ZRS. ZRS protects against data center failure within one region, but not a full regional disaster.
