A Windows VM must run a bootstrap script during provisioning to install a monitoring agent and write configuration files. The administrator does not want to log in interactively, and the script must be runnable again after the VM is rebuilt. Which two Azure compute components should be used? Select two.
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
Azure VM Agent
This is the runtime required for Azure to deliver and manage VM extensions.
B
Best answer
Custom Script Extension
This extension runs initialization commands and file-copy actions during or after provisioning.
C
Distractor review
Boot diagnostics
Boot diagnostics helps troubleshoot startup, but it does not execute provisioning scripts.
D
Distractor review
Availability zone
A zone improves resiliency, but it has no role in running post-deployment configuration tasks.
E
Distractor review
Ephemeral OS disk
An ephemeral OS disk changes disk persistence behavior, but it does not perform scripted setup.
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: Azure VM Agent — The Azure VM Agent is required for the platform to deliver and manage extensions inside the guest operating system. The Custom Script Extension is the component that actually runs the bootstrap commands to install software and write configuration files without interactive sign-in. Together, they allow the administrator to automate first-boot and rebuild-time setup consistently. This is the standard compute pattern for repeatable VM configuration during provisioning. Why others are wrong: Boot diagnostics is for diagnosing boot problems, not running provisioning logic. Availability zones provide resiliency but do not help with configuration automation. An ephemeral OS disk affects how the OS disk is stored and recreated, but it does not replace the guest agent or an extension for scripted setup. Those options are common Azure terms, but none of them performs the required initialization task.
