- A
A storage account access key, because it can be limited to one container by policy.
Why wrong: An account key grants broad access to the storage account and cannot be scoped safely to a single container in the way the scenario requires.
- B
A container-level SAS token backed by a stored access policy, so you can limit and revoke access.
A container-level SAS with a stored access policy is ideal for temporary access to one container. It avoids sharing the account key, limits permissions and lifetime to exactly what is needed, and gives you a revocation point through the stored access policy. That combination is safer than broad key-based access and more operationally flexible than changing account-wide settings.
- C
Anonymous public access on the container, because it is the easiest way to time-limit access.
Why wrong: Anonymous public access does not provide controlled temporary access and cannot be limited or revoked as precisely as a SAS with a stored access policy.
- D
Azure RBAC on the storage account only, because RBAC automatically expires after a few hours.
Why wrong: RBAC assignments do not automatically expire after a few hours unless managed through separate governance processes. RBAC is useful for authenticated users and apps, but not for a short-lived external access token.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage 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.
A contractor needs temporary access to upload and download files in only one blob container for 8 hours. You do not want to share the storage account key, and you want to revoke access later without affecting other containers. What should you create?
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
A container-level SAS token backed by a stored access policy, so you can limit and revoke access.
A container-level SAS token backed by a stored access policy is the correct solution because it allows you to grant temporary, scoped access to a single blob container without exposing the storage account key. The stored access policy enables you to revoke the SAS token at any time by modifying or deleting the policy, which immediately invalidates all tokens associated with it, without affecting other containers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Why this is correct
A container-level SAS with a stored access policy is ideal for temporary access to one container. It avoids sharing the account key, limits permissions and lifetime to exactly what is needed, and gives you a revocation point through the stored access policy. That combination is safer than broad key-based access and more operationally flexible than changing account-wide settings.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a container-level SAS with a stored access policy, thinking a SAS alone provides revocability, but without a stored access policy, a SAS token cannot be revoked before its expiry time.
Trap categories for this question
Scenario analysis trap
An account key grants broad access to the storage account and cannot be scoped safely to a single container in the way the scenario requires.
Detailed technical explanation
How to think about this question
A stored access policy is defined on a container via the Set Container ACL REST API, specifying permissions and expiry. When you generate a SAS token referencing that policy, the SAS inherits the policy's constraints; revoking the policy (by deleting or modifying it) immediately invalidates all SAS tokens tied to it, even if the tokens themselves have not expired. This is critical for scenarios like contractor access where you need to ensure access can be terminated at any moment without waiting for token expiry.
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.
