Question 3

What is Zone-Redundant Storage (ZRS)

Answer 3

• Secondary region only available in read-only is primary goes down and failover happens

Answer 6

No, read-only access becomes available after an outage and subsequent failover.

Question 7

How does (Read-Access) RA-GRS and RA-GZRS differe from their non RA counterparts (GRS and GZRS)?

Answer 7

Allows for read-access in the secondary region at anytime.
