Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
You need to store billions of small log entries (each ~200 bytes) written in chronological order from multiple producers. The logs are read sequentially in bulk once per day. You need to maximize write throughput and minimize storage costs. Which Azure Storage solution should you choose?
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
Append Blob in Blob Storage
Append Blob is optimized for append operations and can handle high write throughput for sequential logs. It supports atomic appends and has a simple programming model.
B
Distractor review
Block Blob in Blob Storage with high block count
Block Blobs can be used for appending by managing block IDs, but they are not as efficient as Append Blobs for this scenario. Block Blobs have a block limit (50,000) and require more complex logic.
C
Distractor review
Azure Data Lake Storage Gen2 with hierarchical namespace
Data Lake Storage Gen2 is built on top of Blob Storage and is optimized for big data analytics and directory structures, not specifically for high-throughput append-only logs.
D
Distractor review
Azure Files with SMB protocol
Azure Files provides fully managed file shares, but it is not optimized for high-scale append operations and may have performance limitations for billions of small 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.

You are developing an Azure Function that processes messages from an Azure Service Bus queue. The function uses a Service Bus queue trigger and runs on a Consumption Plan. The queue receives a high volume of messages in bursts. You need to ensure that the function scales out to handle the load but does not exceed 10 concurrent instances. Which configuration should you apply?

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 in Blob Storage — Append Blobs are specifically optimized for append operations. They allow new data to be added to the end of the blob efficiently, making them ideal for sequential logging from multiple producers. Block Blobs can be used for append-style writes but require managing block IDs and have a limit of 50,000 blocks. Append Blobs have no such block limit (they can have up to 50,000 append blocks, each up to 4 MB, but the append operation is atomic and simpler). For high-throughput append-only workloads, Append Blobs are the recommended choice. Azure Data Lake Storage Gen2 is better for big data analytics with hierarchical namespace. Azure Files is for SMB file shares and not optimized for high-scale append-only logs.
