The correct answer is that the upload succeeds if the SAS token has write permission. This is because a Shared Access Signature (SAS) token provides delegated, time-limited access to a specific resource, overriding the container’s public access level. Even when publicAccess is set to None in the ARM template, a valid SAS token with the appropriate permissions—such as write—grants the bearer the right to perform the requested operation, like uploading a blob. On the AZ-204 exam, this scenario tests your understanding of Azure Blob Storage security, specifically how SAS tokens bypass anonymous access restrictions. A common trap is assuming that a private container blocks all access, but remember: SAS tokens are designed precisely for this purpose. For a quick memory tip, think “SAS beats None”—a SAS token with write permission will always succeed on a private container, as long as the token itself is valid and not expired.
AZ-204 Practice Question: Connect to and consume Azure services and third-party services
This AZ-204 practice question tests your understanding of connect to and consume azure services and third-party services. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Refer to the exhibit. A developer deploys this ARM template to create a blob container. Later, they attempt to upload a file to the container using a SAS token. What is the result?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The upload succeeds if the SAS token has write permission.
Option C is correct. The container has publicAccess set to None, meaning no anonymous access. However, a SAS token provides delegated access, so uploads with a valid SAS token will succeed. Option A is wrong because SAS tokens are still valid; Option B is wrong because SAS does not require public access; Option D is wrong because the container is created.
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.
✗
The upload succeeds only if the SAS token includes read permission.
Why it's wrong here
SAS token for upload must include write permission, not read.
✗
The container is not created because publicAccess is set to None.
Why it's wrong here
publicAccess=None is a valid setting; the container is created.
✓
The upload succeeds if the SAS token has write permission.
Why this is correct
A SAS token with write permission allows upload to a private container.

✗
The upload fails because the container is private.
Why it's wrong here
SAS tokens provide access even to private containers.
Common exam traps
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.
Detailed technical explanation
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.

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.
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.
