Which TWO Azure Storage redundancy options protect your data against a complete regional disaster? (Select TWO)
Answer options:
A.
Locally redundant storage (LRS)
B.
Zone-redundant storage (ZRS)
C.
Geo-redundant storage (GRS)
D.
Geo-zone-redundant storage (GZRS)
E.
Premium block blobs
How to approach this question
Look for the options that include 'Geo' in the name, indicating cross-region replication.
Full Answer
To protect against regional disasters, data must be replicated to a secondary region. Both Geo-redundant storage (GRS) and Geo-zone-redundant storage (GZRS) replicate data to a paired region hundreds of miles away.
Common mistakes
Selecting ZRS. ZRS protects against datacenter failures, but not a full region failure.
