A media company stores project video assets in Azure Blob Storage. The business requires the data to survive a single availability zone outage in the primary region. In addition, if the primary region becomes unavailable, operations staff must still be able to read the most recently replicated copy from the secondary region right away, even if writes are temporarily unavailable. Which redundancy option best meets this requirement?

ZRS

Zone-redundant storage survives a zone failure, but it does not provide a readable secondary region.

GZRS

Geo-zone-redundant storage adds geo-replication, but the secondary region is not directly readable.

RA-GRS

Read-access geo-redundant storage gives secondary read access, but it does not protect against zone failure in the primary region.

What does this AZ-104 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: RA-GZRS — RA-GZRS is the only option that satisfies both parts of the requirement. It protects data against a zone outage by storing replicas across zones in the primary region, and it also replicates to a paired secondary region. Because it is read-access enabled, administrators can still read the secondary endpoint if the primary region is unavailable. That makes it the best fit when both zone resilience and immediate read-only disaster recovery are required. Why others are wrong: ZRS handles zone failure only and has no secondary region. GZRS adds cross-region replication but does not allow direct reads from the secondary endpoint. RA-GRS allows secondary reads, but it does not provide zone redundancy in the primary region. The scenario requires both capabilities at the same time, so those alternatives each miss one critical requirement.

What should I do if I get this AZ-104 question wrong?

Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
