- A
Service SAS, because it grants scoped access to a container or blob for a limited time.
A service SAS can grant short-lived access with precise permissions and scope.
- B
User delegation SAS, because it is issued with Microsoft Entra ID and supports limited-time access.
A user delegation SAS is a secure SAS option backed by Entra ID authentication.
- C
Storage account shared key, because it can be time-limited when copied into an email.
Why wrong: A shared key is a long-lived secret and should not be shared for temporary partner access.
- D
Anonymous access, because it can be enabled for the container and expires automatically after 12 hours.
Why wrong: Anonymous access is not time-scoped in that way and is not appropriate for controlled uploads.
- E
Resource lock, because it can restrict the partner to one container without requiring any token.
Why wrong: Resource locks protect resources from changes; they do not provide authenticated upload 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. A key principle to apply: service SAS provides delegated access to specific Azure Storage resources.. 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 must upload files to one blob container for 12 hours. You do not want to share the storage account key. Which two temporary access methods can be used? Select two.
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
Service SAS, because it grants scoped access to a container or blob for a limited time.
Option A is correct because a Service SAS (Shared Access Signature) allows you to delegate limited-time, scoped access to a specific container or blob without exposing the storage account key. It can be configured with a start time, expiry time, and permissions (e.g., write, read), making it ideal for a 12-hour upload window. This method ensures the partner can only access the designated container for the required duration.
Key principle: Service SAS provides delegated access to specific Azure Storage resources.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse a Service SAS with the storage account shared key, mistakenly thinking the key can be time-limited when shared, or they overlook that anonymous access lacks any expiry mechanism and cannot be used for controlled, temporary access.
Detailed technical explanation
How to think about this question
A Service SAS is generated using the storage account key and signed with HMAC-SHA256, allowing granular control over permissions (e.g., create, write), resource types (container, blob), and time constraints via the signed expiry (se) parameter. In contrast, a User Delegation SAS uses Microsoft Entra ID (formerly Azure AD) to sign the token with a user delegation key, which is obtained via the Azure Storage REST API and provides an additional layer of security by not requiring the account key. Both methods support IP address restrictions and allowed protocols (HTTPS) to further tighten access.
KKey Concepts to Remember
- Service SAS provides delegated access to specific Azure Storage resources.
- It is secured with the storage account key and grants permissions for a defined period.
- Permissions can be granularly set (read, write, list, delete, add, create, update, process).
- A Service SAS can be scoped to a service, container, or blob level.
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
Service SAS provides delegated access to specific Azure Storage resources.
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.
