Full question →mediummultiple choiceObjective-mapped
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?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
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
Distractor review
The storage account key, because it is easier for external users to use.
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
Distractor review
A management group role assignment, because RBAC can restrict access to one blob container.
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
Distractor review
A private endpoint, because it grants the partner write access over a private IP.
Private endpoints control network path, not user authorization. They do not grant file upload permissions by themselves.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
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.
Technical deep dive
How to think about this question
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.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: A container-level SAS token with write permission and a 24-hour expiry. — A container-level SAS is the best fit because it provides temporary delegated access without exposing the storage account key. You can limit the token to the exact container, assign only the needed write permission, and set a 24-hour expiration. This is a common Azure storage pattern when you must give an external party short-lived access with minimal scope. Why others are wrong: The storage account key is too broad and long-lived for a limited external transfer. RBAC at management group scope is unrelated and far too permissive for a simple upload need. A private endpoint only changes network connectivity; it does not authorize the partner to upload files, so it cannot solve the access requirement alone.
