- A
A container-level SAS token with write permission and a 24-hour expiry.
A SAS token is the right tool for short-lived, scoped access to one container. It avoids sharing the storage account key, and you can limit the permissions to write only with a precise expiration time. That makes it well suited for partner uploads, temporary transfers, and other delegated storage tasks.
- B
The storage account key, because it is easier for external users to use.
Why wrong: The account key grants broad access to the entire storage account and is not scoped to one container. It also exposes a long-lived secret unnecessarily.
- C
A management group role assignment, because RBAC can restrict access to one blob container.
Why wrong: Management group scope applies to governance and RBAC, but external partners do not need broad administrative permissions for this upload scenario. It is far too coarse for file transfer access.
- D
A private endpoint, because it grants the partner write access over a private IP.
Why wrong: Private endpoints control network path, not user authorization. They do not grant file upload permissions by themselves.
Quick Answer
The answer is a container-level SAS token with write permission and a 24-hour expiry. This is correct because a Shared Access Signature (SAS) token provides delegated, time-limited access to a specific Azure resource—here, a single blob container—without ever exposing the storage account key, which satisfies the partner’s need to upload files securely for only 24 hours. On the AZ-104 exam, this scenario tests your understanding of SAS token scope and permissions; a common trap is choosing a service-level SAS or account-level SAS, which grant broader access than intended. Remember that container-level SAS tokens are scoped to the container resource, and you must explicitly set the write permission (add/create) and the expiry window. Memory tip: “Container SAS, write pass, 24-hour glass”—if the requirement says “no key sharing” and “single container only,” always reach for a container-scoped SAS with a tight expiry.
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 partner company needs to upload files to a single blob container for the next 24 hours. The partner should not receive the storage account key, and the access should be limited to that container only. Which access mechanism should you provide?

Correct answer & explanation
A container-level SAS token with write permission and a 24-hour expiry.
A container-level SAS token with write permission and a 24-hour expiry is correct because it provides time-limited, delegated access to a specific blob container without exposing the storage account key. The SAS token is generated with the container as the resource scope, write permission (add/create), and an expiry time of 24 hours, meeting all requirements: no key sharing, container-only access, and time-bound access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct

- ✗
The storage account key, because it is easier for external users to use.
Why it's wrong here
The account key grants broad access to the entire storage account and is not scoped to one container. It also exposes a long-lived secret unnecessarily.
- ✗
A management group role assignment, because RBAC can restrict access to one blob container.
Why it's wrong here
Management group scope applies to governance and RBAC, but external partners do not need broad administrative permissions for this upload scenario. It is far too coarse for file transfer access.
- ✗
A private endpoint, because it grants the partner write access over a private IP.
Why it's wrong here
Private endpoints control network path, not user authorization. They do not grant file upload permissions by themselves.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse SAS tokens with storage account keys, thinking a key is simpler for external users, or mistakenly believe RBAC at a management group scope can be narrowed to a single container, when in fact RBAC for containers requires the scope to be the container itself (via Azure RBAC for Data Actions) and is not available at management group level.

Detailed technical explanation
How to think about this question
A container-level SAS token is generated using the storage account key (or a user delegation key) and includes a signature, expiry time, and permissions encoded in the URI. The SAS token can be created via Azure Portal, Azure CLI (az storage container generate-sas), or programmatically using the Azure Storage SDK, and it supports granular permissions like Create, Write, Delete, and List. In real-world scenarios, SAS tokens are ideal for temporary partner access because they can be revoked by regenerating the account key or user delegation key, and they support IP restrictions and allowed protocols (HTTPS only) for additional security.
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.

Same concept, more angles
2 more ways this is tested on AZ-104
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A contractor must import data into one blob container for six hours. The contractor should not receive the storage account key, and access must be limited to that container only. Which credential should the administrator generate?
medium- A.A storage account access key, because it can be copied into the import tool.
- ✓ B.A user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.
- C.A shared key connection string, because it works with any tool that needs blob access.
- D.A managed identity token, because the contractor can use it outside Azure directly.
Why B: A user delegation SAS is signed with Microsoft Entra credentials (formerly Azure AD) and can be scoped to a specific blob container with a time limit. This meets the requirement of granting the contractor access only to that container for six hours without exposing the storage account key.
Variation 2. A contractor needs to upload data into one specific blob container for six hours. The administrator must avoid sharing the storage account key and should grant only the minimum permissions needed. Which access method should be used?
medium- ✓ A.A service SAS scoped to the container with write permission and an expiry time in six hours.
- B.The storage account access key, because it is easier to revoke later.
- C.A shared key rotation policy, because it grants time-limited access to one container.
- D.A user-assigned managed identity assigned to the contractor’s laptop.
Why A: A service SAS scoped to the container with write permission and an expiry time of six hours is correct because it provides time-limited, delegated access to a specific blob container without exposing the storage account key. This meets the requirement of granting only the minimum permissions needed (write) for the six-hour duration, and the SAS can be revoked by regenerating the storage account key if necessary.
