AZ-204 Develop for Azure storage Practice Question
You are designing a solution to store and serve large media files (500 MB to 2 GB) to a global audience. The files must be accessible via HTTPS with low latency. Which Azure Storage option should you use?
⚠ Common exam trap
Many candidates confuse Azure Files (which supports SMB and REST) as a viable option for global media delivery, but it lacks built-in CDN integration and is not designed for low-latency HTTPS serving to a global audience.
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
✓
Azure Blob Storage with Azure CDN
Azure Blob Storage is optimized for storing large, unstructured data like media files, and integrating it with Azure CDN caches content at edge nodes worldwide, reducing latency for global users. HTTPS access is natively supported, and CDN ensures low-latency delivery by serving files from the nearest point of presence (PoP).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Blob Storage with Azure CDN
Why this is correct
Azure Blob Storage is highly optimized for storing massive amounts of unstructured data, including large media files, offering excellent scalability, durability, and cost-effectiveness. When combined with Azure CDN, it provides a robust solution for serving content globally by caching media at edge locations closer to users. This significantly reduces latency and improves throughput, ensuring a superior user experience for media consumption worldwide by minimizing the distance data travels.
- ✗
Azure Queue Storage
Why it's wrong here
Azure Queue Storage is specifically designed for storing large numbers of messages that can be processed asynchronously by decoupled application components, enabling scalable and resilient architectures. While it provides reliable messaging between services, its fundamental purpose is not for persistent storage or direct serving of large binary files. Messages have strict size limits (up to 64 KB) and lack the necessary file system capabilities for media storage.
- ✗
Azure Files with SMB protocol
Why it's wrong here
Azure Files provides fully managed file shares in the cloud that are accessible via the industry-standard Server Message Block (SMB) protocol or Network File System (NFS), making it suitable for traditional file share scenarios and lift-and-shift applications. However, it is not optimized for high-performance, low-latency global content delivery of large media files directly to end-users. Serving media directly from Azure Files would incur higher latency and potentially higher egress costs compared to a CDN-backed solution designed for public content distribution.
- ✗
Azure Table Storage
Why it's wrong here
Azure Table Storage is a NoSQL key-value store designed for storing large amounts of structured, non-relational data with flexible schemas, ideal for applications requiring fast access to tabular data. It is highly efficient for querying and managing this type of data, but it is fundamentally unsuitable for storing large binary objects like media files. Each entity in Table Storage has size limitations (up to 1 MB), and the service lacks the necessary features for efficient media streaming or direct content serving.
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 |
