A storage account must stay online for applications, but administrators have a temporary freeze on configuration changes. Users can still view the account, but attempts to change the access tier, create a container, or update networking all fail. What most likely caused the behavior?
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
A CanNotDelete lock was applied to the storage account.
CanNotDelete blocks deletion only and would not stop normal write operations such as changing settings.
B
Best answer
A ReadOnly lock was applied to the storage account.
ReadOnly is the correct explanation because it blocks write operations on the locked scope. That includes changing account settings, creating child resources such as containers, and modifying networking configuration. Read-only access still allows users to view the resource, which matches the symptom described in the scenario. This lock is useful when all configuration changes must be paused.
C
Distractor review
An Azure Policy audit assignment was applied to the storage account.
Audit policies report compliance but do not block configuration changes or create this type of failure symptom.
D
Distractor review
The account was moved to a different subscription.
A subscription move would not specifically produce the described write failures while still allowing read access.
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.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: A ReadOnly lock was applied to the storage account. — A ReadOnly lock blocks write operations at the locked scope and on child resources, while still allowing read access. That matches the symptom exactly: users can view the storage account but cannot change settings, create containers, or modify networking. If the requirement were only to prevent deletion, CanNotDelete would be sufficient, but the broader write failures point to ReadOnly. Why others are wrong: CanNotDelete only prevents deletion and would allow the listed configuration changes. Azure Policy audit mode records compliance state but does not block those operations. A subscription move is unrelated to the described access pattern and would not be the likely cause of the failures.
