A contractor needs to upload files to one blob container for the next two hours. The contractor must not learn the storage account key, and access should expire automatically without manual cleanup. What is the best way to grant access?
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
Distractor review
Share the storage account key and ask the contractor to stop using it after two hours.
A storage account key is a long-lived secret that grants very broad access. It does not expire automatically after two hours, and manual cleanup is easy to miss. This approach is much less secure than a scoped temporary SAS.
B
Distractor review
Create an account SAS with broad permissions and send it to the contractor by email.
An account SAS is still a shared secret and can be broader than necessary. It is better than a storage key, but it is not the most secure choice when Entra ID is available. It also does not give the least-privilege, identity-based control described in the scenario.
C
Best answer
Generate a user delegation SAS from Entra ID with only the required container permissions and a two-hour expiry.
A user delegation SAS is generated from Entra ID credentials, so the administrator does not expose the storage account key. It can be scoped to a single container, limited to upload permissions, and given a short expiration time. That combination satisfies least privilege and automatic expiration for temporary contractor access.
D
Distractor review
Assign the contractor the Storage Blob Data Contributor role at the storage account scope.
RBAC is a valid authorization model, but it does not automatically expire after two hours. The administrator would need to remove the role assignment manually later. The scenario specifically asks for access that expires automatically, which makes a temporary SAS the better fit.
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.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Generate a user delegation SAS from Entra ID with only the required container permissions and a two-hour expiry. — For short-term external access, a user delegation SAS is the best fit because it uses Entra ID to generate the token rather than exposing the storage account key. The token can be limited to one container, constrained to the required write operation, and set to expire after exactly two hours. That gives the contractor temporary access with no lingering secret to manage manually. Why others are wrong: A storage account key is too powerful and does not expire on its own. An account SAS is temporary, but it is still broader than necessary and not as identity-based as a user delegation SAS. RBAC is useful for ongoing access, but it does not satisfy the automatic expiration requirement for a short external engagement.
