Full question →mediummultiple choiceObjective-mapped
A company runs a data analytics workload that processes large amounts of unstructured data (images and videos). The data is accessed frequently for the first month, then rarely. They need to store the data cost-effectively for 7 years to meet compliance. The solution must support fast retrieval of data within the first month. Which Azure storage solution should they recommend?
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
Best answer
Azure Blob Storage with hot tier for 30 days, then lifecycle management to cool tier for 6 months, then archive tier
Hot tier offers fast access for the first month; lifecycle management moves data to cool/archive to reduce cost.
B
Distractor review
Azure Blob Storage with premium tier for 30 days, then lifecycle to archive tier
Premium tier is optimized for low latency but is significantly more expensive than hot tier; not cost-effective.
C
Distractor review
Azure Files with lifecycle management
Azure Files is suitable for SMB/NFS file shares, not for large-scale unstructured data like images/videos.
D
Distractor review
Azure Disk Storage with snapshots
Disk storage is for VM disks, not for storing raw unstructured data; snapshots are incremental backups.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Blob Storage with hot tier for 30 days, then lifecycle management to cool tier for 6 months, then archive tier — Azure Blob Storage with lifecycle management allows moving data automatically from hot (frequent access) to cool (infrequent) and then to archive (rarely accessed) tiers. Hot tier provides fast access for the first month. After that, data can be moved to archive to minimize cost. Premium tier is expensive and unnecessary. Azure Files is for file shares, not large unstructured data. Disk storage is for VM disks, not archival.
