A multinational company stores large amounts of unstructured data (documents, images) that must be read with low latency from multiple global regions. Data is written primarily in one region but read globally. Cost optimization is a key requirement. Which Azure storage replication option should they use?

A multinational company stores large amounts of unstructured data (documents, images) that must be read with low latency from multiple global regions. Data is written primarily in one region but read globally. Cost optimization is a key requirement. Which Azure storage replication option should they use?

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

Azure Blob Storage with geo-redundant storage (GRS)

Incorrect. GRS provides a secondary region for failover, but data cannot be read from the secondary unless a failover occurs, so it does not support low-latency global reads.

B

Best answer

Azure Blob Storage with read-access geo-redundant storage (RA-GRS)

Correct. RA-GRS replicates data to a secondary region and provides a read-only endpoint, allowing low-latency reads from the secondary region without the cost of premium storage.

C

Distractor review

Azure Files with premium shares

Incorrect. Premium Azure Files provide high performance but are cost-prohibitive for large-scale unstructured data and do not natively offer geo-replication for global reads.

D

Distractor review

Azure NetApp Files

Incorrect. Azure NetApp Files is an enterprise-grade file share service that is expensive and not optimized for cost-effective global read access of unstructured data.

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.

FAQ

Questions learners often ask

What does this AZ-305 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Azure Blob Storage with read-access geo-redundant storage (RA-GRS) — Read-access geo-redundant storage (RA-GRS) provides a secondary read-only endpoint, allowing global readers to access data with low latency from the secondary region while minimizing write costs. Geo-redundant storage (GRS) does not permit reads from the secondary without failover, and premium options are more expensive.
