- A
Grant the partner Contributor access on the storage account
Why wrong: Contributor is broader than needed and still requires the partner to have an identity in the tenant.
- B
Create a user delegation SAS with write permission and a short expiration time
A user delegation SAS provides temporary access without exposing the storage account key and can be tightly scoped.
- C
Share the storage account access key and let the partner create their own token
Why wrong: Sharing the account key exposes full secret material and defeats the requirement to avoid key distribution.
- D
Enable anonymous public write access on the container
Why wrong: Anonymous write access is not a secure or controlled way to grant temporary partner access.

AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 partner company needs write access to a single blob container for 24 hours. The partner does not have an Azure subscription in your tenant, and the team does not want to share the storage account key. Which access method is the best choice?

Correct answer & explanation
✓
Create a user delegation SAS with write permission and a short expiration time
A user delegation SAS is the best choice because it provides time-limited, scoped write access to a specific blob container without exposing the storage account key. It is secured with Azure AD credentials and can be configured with a short expiration time (e.g., 24 hours), meeting the partner's requirement for temporary access. This method ensures the partner does not need an Azure subscription in your tenant and avoids sharing the account key.
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.
- ✗
Grant the partner Contributor access on the storage account
Why it's wrong here
Contributor is broader than needed and still requires the partner to have an identity in the tenant.
When this WOULD be correct
This option would be correct if the partner needed full management access to the storage account (e.g., to configure networking or monitoring) for an indefinite period, and the partner had an Azure subscription in the same tenant, allowing RBAC role assignment.
- ✓
Create a user delegation SAS with write permission and a short expiration time
Why this is correct
A user delegation SAS provides temporary access without exposing the storage account key and can be tightly scoped.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Share the storage account access key and let the partner create their own token
Why it's wrong here
Sharing the account key exposes full secret material and defeats the requirement to avoid key distribution.
When this WOULD be correct
If the question required granting full access to the entire storage account for an indefinite period and the partner was fully trusted, sharing the access key might be acceptable, though still not best practice.
- ✗
Enable anonymous public write access on the container
Why it's wrong here
Anonymous write access is not a secure or controlled way to grant temporary partner access.
When this WOULD be correct
If the requirement were to allow anonymous read access to a container for public content (e.g., a static website), and write access is not needed, then enabling anonymous public read access would be correct.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Create a user delegation SAS with write permission and a short expiration timeCorrect answer▾
Why this is correct
A user delegation SAS provides temporary access without exposing the storage account key and can be tightly scoped.
✗Grant the partner Contributor access on the storage accountWrong answer — click to see why▾
Why this is wrong here
Granting Contributor access on the storage account gives the partner full control over the entire storage account, including all containers and blobs, and allows management operations like deleting the account. This exceeds the requirement of write access to a single container for only 24 hours and violates the principle of least privilege.
★ When this WOULD be the correct answer
This option would be correct if the partner needed full management access to the storage account (e.g., to configure networking or monitoring) for an indefinite period, and the partner had an Azure subscription in the same tenant, allowing RBAC role assignment.
Why candidates choose this
Candidates may think that Contributor access is a standard way to grant permissions in Azure and might overlook that it provides far more access than needed, especially for a temporary and scoped requirement.
✗Share the storage account access key and let the partner create their own tokenWrong answer — click to see why▾
Why this is wrong here
Sharing the storage account access key grants full administrative access to the entire storage account, not just the single container, and violates the requirement to not share the key.
★ When this WOULD be the correct answer
If the question required granting full access to the entire storage account for an indefinite period and the partner was fully trusted, sharing the access key might be acceptable, though still not best practice.
Why candidates choose this
Candidates may think sharing the key is simpler and still allows the partner to generate their own SAS, overlooking the security risk of exposing the key.
✗Enable anonymous public write access on the containerWrong answer — click to see why▾
Why this is wrong here
Enabling anonymous public write access on the container would allow anyone on the internet to write to the container, violating security requirements and providing uncontrolled access beyond the intended partner.
★ When this WOULD be the correct answer
If the requirement were to allow anonymous read access to a container for public content (e.g., a static website), and write access is not needed, then enabling anonymous public read access would be correct.
Why candidates choose this
Candidates may think anonymous access is simpler than SAS, or confuse public read scenarios with the write requirement, overlooking the severe security risk of public write.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a user delegation SAS with a service SAS or account SAS, or mistakenly think that granting RBAC roles like Contributor is the simplest way to provide access, without realizing it grants far more permissions than needed and violates the principle of least privilege.
Detailed technical explanation
How to think about this question
A user delegation SAS is signed with Azure AD credentials (via a user delegation key) rather than the storage account key, allowing fine-grained control over permissions, resource scope, and expiration. The SAS token includes parameters such as `signedpermissions` (e.g., 'w' for write), `signedexpiry` (set to 24 hours), and `signedresource` (e.g., 'c' for container), ensuring the token is valid only for the specified container and time window. Under the hood, the SAS is generated using the Azure Storage REST API or SDK, and the user delegation key is obtained from Azure AD, which has a maximum lifetime of 7 days, making it ideal for short-term delegated access.
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.
