AZ-204 Develop for Azure storage Practice Question
A storage account for thumbnail metadata must allow an application to read only blobs under one container for two hours. The application should not receive the account key. What should be issued?
⚠ Common exam trap
Candidates often confuse a service SAS with a public access level or account key, failing to recognize that a SAS provides granular, time-bound delegation without exposing the account key, while public access is permanent and account keys grant full control.

Correct answer & explanation
✓
A service SAS scoped to the container with read permission and expiry
A service SAS scoped to a container with read permission and an expiry of two hours is the correct approach because it provides delegated, time-limited access to specific blobs under that container without exposing the storage account key. The SAS token is generated using the account key but the application only receives the token, not the key itself, ensuring the key remains secure. This meets the requirement for read-only access to a single container for a limited duration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A public access level on the container
Why it's wrong here
Public access exposes data to anonymous users.
- ✓
A service SAS scoped to the container with read permission and expiry
Why this is correct
A service SAS can grant limited, time-bound permissions without exposing account keys.
- ✗
A management group assignment
Why it's wrong here
Management groups govern Azure resources but do not provide temporary blob read tokens.
- ✗
The storage account access key
Why it's wrong here
Account keys grant broad access and are not appropriately scoped.
