AZ-204 Practice Question: SAS token scope misconfiguration allowing upload…
This AZ-204 practice question tests your understanding of sas token scope misconfiguration allowing upload…. 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. A key principle to apply: shared Access Signature. 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.
External partners are given Shared Access Signatures to upload product images to a specific Blob Storage container named 'images'. A partner reports accidentally uploading files to the 'contracts' container, which should not be accessible. What is the most likely configuration mistake?
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.
Best answer
The SAS was generated at the storage account level, granting write access that applies to multiple containers rather than being scoped to the 'images' container only
An account SAS with sr=c (container) permission and no container restriction grants access to all containers. A container SAS is generated with a specific container name in the signed resource URI (e.g., https://account.blob.core.windows.net/images?sig=...), making it impossible for the holder to use the SAS against any other container.
Distractor review
The SAS expiry time is too long, giving partners time to discover and access other containers
SAS expiry controls the time window during which the SAS is valid but does not affect which containers the SAS can access. Even an expired SAS has a defined resource scope — changing the expiry does not change the scope.
Distractor review
The partner used a storage account key instead of the provided SAS token
An account key grants unrestricted access to the entire storage account, which would be a far more severe security incident. The scenario describes a partner using a SAS — the SAS is the control that needs to be scoped correctly.
Distractor review
The SAS was signed with a stored access policy that did not name the correct container
Stored access policies are attached to a specific container. If a SAS references a stored access policy, it inherits the policy's permissions — but the SAS's signed resource URI still determines which container it grants access to, not the policy name.
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
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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.

FAQ
Questions learners often ask
What does this AZ-204 question test?
Shared Access Signature
What is the correct answer to this question?
The correct answer is: The SAS was generated at the storage account level, granting write access that applies to multiple containers rather than being scoped to the 'images' container only — Shared Access Signatures have two scopes relevant here: account-level SAS and service-level (container) SAS. An account-level SAS can grant access to multiple storage services and containers in the account. A container-level SAS is scoped to a single named container. If the SAS was generated at the account level with write permission across containers, the partner can upload to any container. The fix is to generate a container-level SAS that explicitly specifies the 'images' container as the resource scope.
