An existing application in AppSubnet1 must access an Azure Storage account. The team does not want to add a private endpoint or change DNS records, but they do want to allow access only from AppSubnet1. Which configuration should the administrator use?
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
Enable the Microsoft.Storage service endpoint on AppSubnet1 and restrict the storage account to selected virtual networks.
A service endpoint lets traffic from the subnet reach the storage account over the Azure backbone while the storage firewall can allow only that subnet. This matches the requirement to avoid private endpoints and DNS changes. The access is still limited to the approved subnet identity, which is what the storage firewall evaluates.
B
Distractor review
Create a private endpoint and remove all public network access from the storage account.
This would require private DNS changes and a different access model, which the requirement explicitly excludes.
C
Distractor review
Add a network security group rule that allows outbound TCP 443 to the storage account.
An NSG rule does not grant access to a storage account by itself and cannot replace storage firewall configuration.
D
Distractor review
Enable peering between AppSubnet1 and the storage account network.
Storage accounts are not accessed through VNet peering, so this does not provide the needed control.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Enable the Microsoft.Storage service endpoint on AppSubnet1 and restrict the storage account to selected virtual networks. — A service endpoint is the right fit when the organization wants to restrict storage access to a subnet without introducing a private endpoint or DNS changes. After enabling the Microsoft.Storage service endpoint on AppSubnet1, the storage account can be configured to allow only selected virtual networks. That gives subnet-based access control while keeping the service on its public endpoint and avoiding private DNS management. Why others are wrong: A private endpoint would change the name-resolution model and contradict the stated constraint. An NSG rule cannot grant PaaS authorization; it only filters packets. Peering does not apply to a storage account because it is not a VNet resource. The storage firewall and service endpoint combination is the intended solution here.
