Full question →mediummultiple choiceObjective-mapped
A company has an Azure virtual network with a subnet that hosts Azure virtual machines. They want to restrict access to an Azure SQL Database so that only traffic originating from that specific subnet is allowed. They have enabled a service endpoint for Microsoft.Sql on the subnet and configured the SQL server firewall to allow only that subnet's virtual network rule. However, connections from the VMs to the SQL database are failing with an authorization error. What is the most likely cause?
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
The service endpoint for Microsoft.Sql was not enabled on the subnet before creating the firewall rule
The service endpoint must be enabled on the subnet before or concurrently with the firewall rule. If enabled after, the rule may not work until it is updated or re-created.
B
Distractor review
The SQL server's firewall also has a rule allowing all Azure services, which overrides the VNet rule
Allowing all Azure services provides broader access, not less; it would not cause an authorization error.
C
Distractor review
The virtual machine's operating system firewall is blocking outbound traffic
While possible, OS firewall issues typically produce different error messages (e.g., connection timeout) and are less specific to the service endpoint scenario.
D
Distractor review
The subnet's NSG is blocking outbound traffic to Azure SQL
An NSG blocking outbound traffic would cause a similar issue, but the most likely cause related to the described configuration is the service endpoint not being properly enabled.
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-500 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: The service endpoint for Microsoft.Sql was not enabled on the subnet before creating the firewall rule — The most common issue is that the service endpoint was not enabled on the subnet before the firewall rule was created. The virtual network rule in the SQL firewall requires the endpoint to be active and properly associated. If the endpoint is enabled after the rule, the rule might not take effect until re-created. Allowing all Azure services would permit traffic, not block it. While OS or NSG could cause issues, the authorization error points to a network access problem typically resolved by the service endpoint configuration.
