Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company has a large dataset of historical financial records that must be retained for 10 years to comply with regulatory requirements. The data is accessed only a few times per year during audits. When accessed, a retrieval delay of up to 15 hours is acceptable. The company wants to minimize storage costs for this dataset. Which Azure Blob storage access tier should the company 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
Hot tier
The Hot tier is optimized for frequent access and has higher storage costs. It is not the most cost-effective choice for data that is accessed only a few times per year.
B
Distractor review
Cool tier
The Cool tier is for infrequently accessed data with lower storage costs than Hot, but it still charges higher storage fees than Archive and has lower retrieval latency. It is not the cheapest option given the very rare access pattern.
C
Best answer
Archive tier
The Archive tier offers the lowest storage costs and is designed for long-term retention of data that is rarely accessed. Retrieval times are measured in hours (up to 15 hours), which matches the company's acceptable delay. This is the most cost-effective choice.
D
Distractor review
Premium tier
The Premium tier is for high-performance block blob storage with low latency and high storage cost. It is intended for frequently accessed data and interactive workloads, not for archival data with minimal access.
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-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Archive tier — Azure Blob storage offers three access tiers optimized for different usage patterns. The Hot tier is for frequently accessed data with low latency and high storage cost. The Cool tier is for infrequently accessed data with lower storage cost and slightly higher access cost. The Archive tier is for rarely accessed data with the lowest storage cost but higher retrieval latency (hours). Since the data is accessed only a few times per year and a 15-hour retrieval delay is acceptable, the Archive tier provides the lowest storage cost and meets the requirements.
