Full question →hardmultiple choiceObjective-mapped
You need to store a large (terabytes) append-only dataset for compliance purposes. The data must be immutable to prevent tampering after writes. You also want to minimize storage cost and achieve high write throughput. Which Azure Storage solution 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
Best answer
Azure Blob Storage with Append Blobs and an immutable blob policy
Correct. Append Blobs are ideal for append operations, and immutability provides tamper-proof storage. Cost-effective for high-volume writes.
B
Distractor review
Azure Data Lake Storage Gen2 with Append Blobs and immutability
Incorrect. While technically possible, Data Lake Storage Gen2 adds cost for the hierarchical namespace and is more suited for analytics purposes, not just append-only immutability.
C
Distractor review
Azure Files with immutable shares
Incorrect. Azure Files provides SMB/NFS file shares, but immutability is not available for all tiers and append writes are not efficient.
D
Distractor review
Azure NetApp Files with immutability
Incorrect. Azure NetApp Files is a high-performance file share for enterprise workloads, not optimized for append-only immutability and is cost-prohibitive for large-scale append data.
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: Azure Blob Storage with Append Blobs and an immutable blob policy — Azure Blob Storage with an immutable blob policy (time-based retention) and Append Blobs is the best fit: Append Blobs are optimized for append operations, and immutability ensures data cannot be modified or deleted before the retention period ends. Azure Data Lake Storage Gen2 is built on Blob Storage and also supports immutability, but is typically more expensive due to the hierarchical namespace and is unnecessary for the stated requirement for simple append-only workloads. Azure Files and NetApp Files are not designed for append-heavy immutable storage.
