The platform team wants to block deployment of Azure resources in any region except East US and West US. What should they configure?
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.
Best answer
An Azure Policy assignment that uses an allowed locations policy
Azure Policy is designed to enforce configuration rules such as approved regions. An allowed locations policy can deny deployments outside East US and West US, which directly matches the requirement. This is governance, not authorization, so RBAC is not the right tool for controlling where resources can be created.
Distractor review
A Reader role assignment at the management group
Reader only controls access to view resources and cannot block deployment to specific regions.
Distractor review
A CanNotDelete lock on the subscription
A lock prevents deletion or changes to protected resources, but it does not evaluate the deployment region.
Distractor review
A tag requirement enforced only by resource group naming
Tags and naming conventions do not prevent deployments in disallowed Azure regions by themselves.
Common exam trap
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Technical deep dive
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
Standard ACLs match source addresses.
What is the correct answer to this question?
The correct answer is: An Azure Policy assignment that uses an allowed locations policy — Azure Policy is the correct service when you need to enforce a compliance rule such as approved deployment regions. The allowed locations policy can deny any resource creation request that targets a region outside the approved list. RBAC would only answer who can create resources, not where they can be created, so policy is the proper governance control here. Why others are wrong: Reader is read-only and does not control deployments. Locks protect resources from changes or deletion, but they do not validate region placement. Naming conventions or tags are not enforcement mechanisms for Azure region compliance. The requirement is to block noncompliant deployments, which is exactly what Azure Policy does.
