Full question →mediummultiple choiceObjective-mapped
A company stores large amounts of log data in Azure Blob Storage. Logs are accessed frequently for the first 30 days, then rarely accessed afterward, but must be retained for 7 years for compliance. The company wants to minimize storage costs. They need to configure automatic data movement and retention policies. Which combination of Azure Blob Storage access tiers and lifecycle management policy 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
Use Hot tier for 30 days, then use Cool tier for 7 years, with a lifecycle rule to delete after 7 years.
Cool tier is more expensive than Archive tier for long-term storage. Archive offers the lowest storage cost, which is better for data that is rarely accessed.
B
Best answer
Use Hot tier for 30 days, then use Archive tier for the remaining period, with a lifecycle rule to delete after 7 years.
Hot tier provides low-latency access during the frequent access period. Archive tier provides the lowest storage cost for data that is rarely accessed. A lifecycle policy can automatically move data from Hot to Archive after 30 days and delete it after 7 years.
C
Distractor review
Use Cool tier for 30 days, then use Archive tier for 7 years, no lifecycle rule needed.
Cool tier is more expensive than Hot tier for frequent access, and without a lifecycle rule the data will not be automatically deleted after 7 years, leading to indefinite storage costs.
D
Distractor review
Use Archive tier immediately, with a lifecycle rule to delete after 7 years.
Archive tier is not suitable for frequent access; reading data from Archive incurs high costs and latency. The data is accessed frequently for the first 30 days.
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: Use Hot tier for 30 days, then use Archive tier for the remaining period, with a lifecycle rule to delete after 7 years. — Using the Hot tier for the initial 30 days minimizes latency and read costs, then moving to the Archive tier provides the lowest storage cost for long-term retention. After 7 years, a lifecycle rule deletes the data. The Cool tier is more expensive than Archive for long-term storage. Starting with Archive would incur high read costs during the frequent access period. Without a lifecycle rule, data would not be automatically deleted after 7 years.
