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.
Your application stores user profile images in Azure Blob Storage. You need to serve these images to users with low latency from a domain name that you own. What should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Azure CDN endpoint with a custom domain and point it to the blob container.
Option B is correct because Azure CDN provides global edge caching, which reduces latency for serving static images from Blob Storage. By configuring a custom domain on the CDN endpoint, you can serve content under your own domain name while benefiting from CDN acceleration. This combination addresses both the low-latency requirement and the custom domain ownership.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable static website hosting and configure a custom domain directly on the storage account.
Why it's wrong here
Custom domain on storage does not provide CDN caching.
✓
Create an Azure CDN endpoint with a custom domain and point it to the blob container.
Why this is correct
Azure CDN provides low-latency content delivery with custom domain support.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure a custom domain in Azure DNS and point it to the storage account endpoint.
Why it's wrong here
Azure DNS provides name resolution, not content delivery acceleration.
✗
Use Azure Front Door with a custom domain.
Why it's wrong here
Front Door is a global load balancer; CDN is more appropriate for static content.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure CDN with Azure Front Door or static website hosting, assuming any custom domain on a storage account automatically provides low latency, but only CDN adds the necessary edge caching layer for static blob content.
Detailed technical explanation
How to think about this question
Azure CDN (e.g., from Microsoft or Verizon) caches blob content at edge nodes (Points of Presence) worldwide, serving requests from the nearest node to the user. The custom domain is configured via a CNAME record in your DNS provider that maps to the CDN endpoint hostname (e.g., `.azureedge.net`), and the CDN endpoint is linked to the blob container as its origin. This setup ensures that even if the storage account is in a single region, users globally experience low latency due to edge caching.
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.
