Exhibit

Provisioning requirement:
- A Windows VM is created from a marketplace image
- IIS must be installed automatically on first boot
- Application files must be copied from Azure Blob Storage
- A bootstrap script named bootstrap.ps1 must run after the VM starts
- No manual RDP steps are allowed

Based on the exhibit, which Azure feature should the administrator use to install software and run the bootstrap script during VM provisioning?

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 Custom Script Extension

The Custom Script Extension is designed to run scripts after deployment and is commonly used for first-boot configuration. It can download files, execute installation commands, and automate bootstrap tasks without requiring manual sign-in. This matches the requirement to install IIS, copy application files, and run bootstrap.ps1 as part of provisioning.

B

Distractor review

A network security group rule allowing RDP from the Internet

Opening RDP only provides interactive access; it does not automate software installation or first-boot scripting.

C

Distractor review

An availability set with two fault domains

Availability sets improve resiliency, but they do not execute provisioning scripts or install software.

D

Distractor review

A managed disk snapshot restored as the operating system disk

A snapshot is for disk recovery, not for running configuration scripts during deployment.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

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?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Azure VM Custom Script Extension — The Azure VM Custom Script Extension is the right tool when you need automation during or immediately after VM provisioning. It can run PowerShell scripts, download content from storage, and install required components such as IIS without manual RDP interaction. The exhibit specifically calls for first-boot configuration and scripted setup, which is exactly the purpose of a VM extension rather than networking or resiliency features. Why others are wrong: RDP access is manual and insecure for this use case. An availability set changes placement for resilience, not provisioning behavior. A disk snapshot helps with recovery, but it does not perform application installation or bootstrap automation.
