Quick Answer
The correct answer is a Shared Access Signature (SAS). A SAS token provides delegated, time-limited access to a specific Azure Storage blob, allowing a user to download a file via a secure URL without exposing the storage account keys. This works by appending the SAS token—which includes permissions, expiry time, and allowed IP ranges—to the blob’s URL, granting granular control over access. On the AZ-500 exam, this concept tests your understanding of securing data at rest and in transit, often appearing in scenarios where you must differentiate between SAS, storage account keys, Azure RBAC, and Azure Front Door. A common trap is confusing SAS with storage account keys, which grant unrestricted full access and cannot be time-limited. Remember: SAS is like a valet key for your car—it gives limited, temporary access to the trunk (blob) without handing over the master key (storage account key).
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
You have an Azure Storage account that contains sensitive documents. You need to generate a time-limited, secure URL that allows a specific user to download a file without requiring storage account keys. What should you use?
Azure Front Door custom domain
Why wrong: Front Door is not for generating secure URLs.
Storage account access key
Why wrong: Access keys grant full access and cannot be time-limited.
Shared Access Signature (SAS)
SAS provides time-limited delegated access to specific resources.
Azure RBAC role assignment
Why wrong: RBAC controls permissions but does not generate a URL for direct access.

Correct answer & explanation
Shared Access Signature (SAS)
Option A is correct because a shared access signature (SAS) token provides delegated access with time-limited permissions. Option B is wrong because a storage account key grants full access and cannot be time-limited. Option C is wrong because Azure RBAC does not generate URLs. Option D is wrong because Azure Front Door is a global load balancer, not a mechanism for generating secure URLs.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Front Door custom domain
Why it's wrong here
Front Door is not for generating secure URLs.
Storage account access key
Why it's wrong here
Access keys grant full access and cannot be time-limited.
Shared Access Signature (SAS)
Why this is correct
SAS provides time-limited delegated access to specific resources.
Related concept
Static NAT maps one inside address to one outside address.
Azure RBAC role assignment
Why it's wrong here
RBAC controls permissions but does not generate a URL for direct access.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AZ-500 NAT questions on configuration and troubleshooting.
