After a Windows VM is deployed, an administrator must install IIS, copy application files, and run a post-deployment configuration script without connecting interactively to the server. Which Azure feature 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
Best answer
Custom Script Extension.
The Custom Script Extension runs post-provisioning commands and scripts on a VM without interactive login.
B
Distractor review
An availability zone assignment.
Zones improve resilience, but they do not execute post-deployment configuration scripts.
C
Distractor review
A route table association.
Route tables control network paths and cannot install software on a VM.
D
Distractor review
A user-assigned managed identity alone.
An identity can authenticate to Azure services, but it does not by itself run installation steps.
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.

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: Custom Script Extension. — The Custom Script Extension is designed for exactly this kind of post-deployment automation. It can download or run scripts after the VM is created, which makes it suitable for installing IIS, copying files, and applying configuration changes without logging on manually. This keeps provisioning repeatable and reduces the need for interactive administration. Why others are wrong: Availability zones improve the placement of the VM but do nothing to install software. Route tables affect packet routing, not guest OS configuration. A user-assigned managed identity can help a VM access Azure resources securely, but it is not a mechanism for executing installation scripts on the operating system.
