- A
Use AzCopy with the --resume parameter.
Why wrong: AzCopy is a standalone tool, not embeddable in an application for custom progress reporting.
- B
Use Page blobs with 512-byte pages.
Why wrong: Page blobs are optimized for random read/write, not for large sequential uploads.
- C
Use the Azure Storage SDK to upload blobs in blocks, and implement pause/resume logic using block IDs.
Block blobs support chunked upload, concurrency, and progress tracking; block IDs enable resume.
- D
Use Append blobs and append data in chunks.
Why wrong: Append blobs are for logging, not for large file uploads with pause/resume.

AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are designing a solution that stores large media files (up to 5 GB each) in Azure Blob Storage. The application must support concurrent uploads with the ability to pause and resume. You need to ensure efficient use of network bandwidth and provide progress reporting. Which approach should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Azure Storage SDK to upload blobs in blocks, and implement pause/resume logic using block IDs.
Option C is correct because Azure Blob Storage supports block blobs, which allow you to upload large files in independent blocks. By using the Azure Storage SDK, you can assign unique block IDs to each block, enabling pause/resume by tracking which block IDs have been committed. This approach also provides fine-grained progress reporting per block and efficient network bandwidth usage through parallel uploads.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
Use Append blobs and append data in chunks.
Why it's wrong here
Append blobs are for logging, not for large file uploads with pause/resume.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse AzCopy's resume capability with programmatic pause/resume, or assume Append blobs are suitable for large file uploads because they support chunking, but they lack the block-level control needed for concurrent uploads and progress tracking.
Detailed technical explanation
How to think about this question
Block blobs use a two-phase commit model: you upload blocks (each up to 100 MB, with a maximum of 50,000 blocks per blob) using unique block IDs, then commit the block list. For pause/resume, you can persist the list of successfully uploaded block IDs (e.g., in a local database) and resume by skipping already-uploaded blocks. The SDK's PutBlock and PutBlockList operations map directly to REST API calls, allowing you to control concurrency and report progress per block.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
