A team needs to deploy 25 identical Ubuntu VMs every month from source control. The deployment must be repeatable, and each VM must include a system-assigned managed identity at creation time. Which approach should be used?
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
Azure portal manual creation of each VM.
Manual portal steps are difficult to repeat consistently and are not source-controlled.
B
Best answer
A Bicep template deployment.
Bicep is declarative, versionable in source control, and can define VM identity settings at deployment time.
C
Distractor review
An Azure Policy assignment at the subscription level.
Policy can enforce compliance, but it does not create a full repeatable deployment from code.
D
Distractor review
An Azure Monitor alert rule that triggers VM creation.
Alerts notify on conditions; they are not the right mechanism for controlled infrastructure deployment.
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 Bicep template deployment. — Bicep is the best answer because it supports declarative infrastructure as code, which means the same template can be checked into source control and deployed repeatedly with consistent results. A VM resource in Bicep can include the identity block so that each machine gets a system-assigned managed identity during provisioning. That combination satisfies repeatability, standardization, and secretless authentication. Why others are wrong: Manual portal deployment is too error-prone and cannot reliably enforce identical settings across monthly builds. Azure Policy is useful for compliance after deployment, but it does not define the deployment itself. Azure Monitor alerts are for observation and response, not for constructing repeatable infrastructure from code.
