- A
A storage account access key, because it can be copied into the import tool.
Why wrong: An account key grants broad access to the entire storage account and is not scoped to one container.
- B
A user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.
A user delegation SAS is the most appropriate credential when you want temporary, scoped access to blob data without exposing the storage account key. It is generated using Microsoft Entra authorization, can be constrained to a specific container, and can expire after six hours. That combination gives the contractor only the access needed for the import task while keeping the underlying account credentials protected.
- C
A shared key connection string, because it works with any tool that needs blob access.
Why wrong: A shared key connection string exposes broad account-level credentials and is not limited to one container.
- D
A managed identity token, because the contractor can use it outside Azure directly.
Why wrong: Managed identities are tied to Azure resources and are not something an external contractor directly receives.
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 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?
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 user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.
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.
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.
- ✗
A storage account access key, because it can be copied into the import tool.
Why it's wrong here
An account key grants broad access to the entire storage account and is not scoped to one container.
- ✓
A user delegation SAS, because it is signed with Microsoft Entra credentials and is time limited.
Why this is correct
A user delegation SAS is the most appropriate credential when you want temporary, scoped access to blob data without exposing the storage account key. It is generated using Microsoft Entra authorization, can be constrained to a specific container, and can expire after six hours. That combination gives the contractor only the access needed for the import task while keeping the underlying account credentials protected.

Why it's wrong here
A shared key connection string exposes broad account-level credentials and is not limited to one container.
- ✗

Why it's wrong here
Managed identities are tied to Azure resources and are not something an external contractor directly receives.
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, mistakenly thinking any SAS is sufficient, but only a user delegation SAS avoids using the storage account key and can be precisely scoped to a single container with time-bound access.
Detailed technical explanation
How to think about this question
A user delegation SAS is created using Azure AD credentials and relies on the `UserDelegationKey` obtained via the `Get User Delegation Key` REST API call. This SAS can be assigned permissions at the container or blob level and includes an expiry time, making it ideal for temporary, scoped access. Under the hood, the SAS token is signed with the user delegation key, which itself is signed with the Azure AD token, ensuring the SAS is tied to the identity that requested it.
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.
