- A
A shared access signature scoped to the container and expiration time
A SAS can grant limited, time-bound access to a specific resource such as one container, without exposing the storage account key.
- B
A new storage account access key
Why wrong: An access key grants broad account-level access and is much wider than the contractor needs.
- C
A management group assignment
Why wrong: Management groups control governance over subscriptions, not temporary file upload access to blob storage.
- D
A private endpoint for the contractor
Why wrong: Private endpoints control network access paths, but they do not provide temporary user authorization by themselves.

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 needs temporary access to upload files into one Azure Blob container for six hours. The administrator does not want to share the storage account key. What should the administrator create?
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 shared access signature scoped to the container and expiration time
A shared access signature (SAS) scoped to the container provides time-limited, delegated access to specific operations (e.g., upload) without exposing the storage account key. By setting an expiration time of six hours, the administrator ensures the contractor can upload files only during that window, after which the token becomes invalid. This meets the requirement for temporary, secure access.
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 shared access signature scoped to the container and expiration time
Why this is correct
A SAS can grant limited, time-bound access to a specific resource such as one container, without exposing the storage account key.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
A new storage account access key
Why it's wrong here
An access key grants broad account-level access and is much wider than the contractor needs.
When this WOULD be correct
If the question required granting full administrative access to a storage account for a trusted internal team member with no time restriction, sharing the access key would be appropriate.
- ✗
A management group assignment
Why it's wrong here
Management groups control governance over subscriptions, not temporary file upload access to blob storage.
When this WOULD be correct
An administrator needs to apply the same Azure Policy, such as requiring tags on all resources, to multiple subscriptions under a management group. Creating a management group assignment would enforce the policy across those subscriptions.
- ✗
A private endpoint for the contractor
Why it's wrong here
Private endpoints control network access paths, but they do not provide temporary user authorization by themselves.
When this WOULD be correct
An administrator needs to ensure that only traffic from a specific virtual network can access a storage account, while blocking all public internet access. In that case, creating a private endpoint 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.
✓A shared access signature scoped to the container and expiration timeCorrect answer▾
Why this is correct
A SAS can grant limited, time-bound access to a specific resource such as one container, without exposing the storage account key.
✗A new storage account access keyWrong answer — click to see why▾
Why this is wrong here
Sharing the storage account access key grants full access to all storage services and containers, which violates the requirement to limit access to a single container for a specific time period.
★ When this WOULD be the correct answer
If the question required granting full administrative access to a storage account for a trusted internal team member with no time restriction, sharing the access key would be appropriate.
Why candidates choose this
Candidates may think that any access key provides limited access, but they overlook that storage account keys grant unrestricted access to all data in the account.
✗A management group assignmentWrong answer — click to see why▾
Why this is wrong here
A management group assignment manages access and policies across multiple subscriptions, not temporary access to a single blob container. It does not provide time-limited, container-specific access.
★ When this WOULD be the correct answer
An administrator needs to apply the same Azure Policy, such as requiring tags on all resources, to multiple subscriptions under a management group. Creating a management group assignment would enforce the policy across those subscriptions.
Why candidates choose this
Candidates may confuse management groups with role assignments or think they can be used to grant granular access, but management groups are for organizing subscriptions and applying governance, not for direct data access.
✗A private endpoint for the contractorWrong answer — click to see why▾
Why this is wrong here
A private endpoint restricts network access to the storage account but does not provide temporary, scoped access to a specific container without sharing the account key.
★ When this WOULD be the correct answer
An administrator needs to ensure that only traffic from a specific virtual network can access a storage account, while blocking all public internet access. In that case, creating a private endpoint would be correct.
Why candidates choose this
Candidates may think a private endpoint provides secure, temporary access by isolating the storage account, but it does not grant time-limited permissions to a specific container.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a SAS with a storage account key, thinking any shared credential is unsafe, or mistakenly choose a private endpoint as a security solution for access control rather than network isolation.
Detailed technical explanation
How to think about this question
A SAS token is generated using the storage account key and includes parameters such as signed permissions (e.g., 'w' for write), signed resource type (e.g., 'c' for container), and signed expiry (e.g., '2025-03-15T14:00:00Z'). The token is appended to the container URL, allowing the contractor to authenticate via HTTPS without knowing the account key. Under the hood, Azure validates the SAS signature using HMAC-SHA256, ensuring the token hasn't been tampered with.
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.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
