Full question →mediummultiple choiceObjective-mapped
A shared resource group contains a VPN gateway and several virtual machines used by the finance department. Administrators must still be able to resize the VMs and update NSG rules, but no one should be able to delete the resource group or anything in it during the quarter-end freeze. Which lock should be applied?
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
Distractor review
ReadOnly lock on the resource group
This would block writes such as resizing VMs and changing NSG rules, which are still required.
B
Best answer
CanNotDelete lock on the resource group
This prevents deletion while still allowing allowed changes like resizing and configuration updates.
C
Distractor review
Management group lock on the subscription
This is broader than necessary and does not target the specific change-control boundary described.
D
Distractor review
Azure Policy deny effect on the resource group
Policy can block deployments, but a lock is the appropriate control for preventing deletion.
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: CanNotDelete lock on the resource group — The CanNotDelete lock is designed for change-control scenarios where resources must remain in place but administrators still need to make routine updates. In this case, the finance team must keep the resource group and its resources from being deleted during a freeze, while still allowing VM resizing and NSG edits. A ReadOnly lock would be too restrictive because it blocks write operations. CanNotDelete provides the right balance of protection and operational flexibility. Why others are wrong: ReadOnly is too aggressive because it blocks management tasks the team still needs to perform. A management group lock is not the right operational boundary for a single resource group freeze and would be harder to target precisely. Azure Policy is used for compliance and deployment behavior, not as the simplest deletion-protection mechanism. CanNotDelete is the lock specifically meant to prevent accidental or unauthorized deletion while leaving normal changes available.
