An application writes millions of small log entries (500 bytes each) daily. The logs are rarely read, and when read, they are accessed sequentially. You need to minimize storage costs and maximize write throughput. Which Azure Blob Storage type should you 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
Block Blob
Block Blobs can be used but they are not optimized for many small append operations; each block incurs overhead.
B
Distractor review
Page Blob
Page Blobs are designed for random read/write patterns (e.g., VHDs) and are not cost-effective for log entries.
C
Best answer
Append Blob
Append Blobs are purpose-built for append-only operations, offering high throughput for log data and efficient sequential reads.
D
Distractor review
Archive Blob
Archive Blob provides lowest storage cost but requires hours to retrieve data, making it unsuitable for frequent writes.
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-204 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Append Blob — Append Blobs are optimized for append operations like logging. They provide high write throughput for small entries and are cost-effective for sequential reads. Block Blobs are better for larger files. Page Blobs are for VHDs. Archive Blob has high latency and is not suitable for frequent writes.
