A finance team stores PDF statements in Azure Blob Storage. The workload must survive a zone failure in the primary region, and if the entire region becomes unavailable, auditors still need read-only access to the copies in the secondary region. Which redundancy option should you choose?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
ZRS, because it keeps copies across zones but does not replicate to another region.
ZRS protects against a zone outage within one region, but it does not provide geo-replication or secondary-region read access.
B
Best answer
RA-GZRS, because it combines zone redundancy with geo-replication and read access to the secondary region.
RA-GZRS is designed for exactly this requirement. It replicates data across zones in the primary region and also asynchronously replicates to a paired secondary region. The read-access feature means you can still retrieve data from the secondary endpoint if the primary region is unavailable, which is useful for audit or continuity scenarios.
C
Distractor review
LRS, because it keeps three copies in a single datacenter and is sufficient for regional resilience.
LRS protects only against localized hardware failures in one datacenter. It does not handle zone failures or regional outages.
D
Distractor review
GRS, because it provides geo-replication and always allows direct reads from the secondary region.
GRS adds geo-replication, but the secondary region is not readable unless you choose the read-access variant. It also does not provide zone redundancy in the primary region.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4

Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
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, because it combines zone redundancy with geo-replication and read access to the secondary region. — RA-GZRS is the best fit because it addresses both failure domains in the requirement. Zone redundancy keeps the primary workload protected against a zone failure, while geo-replication protects against a regional outage. The read-access capability is important here because auditors must be able to open the data from the secondary region if the primary region is down. That combination is more resilient than ZRS or GRS alone. Why others are wrong: ZRS helps with zone failure only, so it misses the secondary-region read requirement. LRS is limited to a single datacenter and is not sufficient for either zone or regional resilience. GRS replicates to another region, but the primary region is not zone-redundant and the secondary endpoint is not readable unless RA-GRS or RA-GZRS is selected.
