Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A Windows VM must install IIS after provisioning and then run a script that registers the server with an internal API by using the VM's managed identity. The same steps must run automatically whenever the VM is deployed from Bicep. What should be added to the deployment?
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 read-only resource lock on the VM resource group
A lock prevents changes, but it does not install software or run deployment scripts.
B
Best answer
A Custom Script Extension on the VM
The Custom Script Extension runs scripted configuration during deployment and is suitable for post-provisioning setup.
C
Distractor review
An availability set containing the VM
Availability sets improve resiliency, but they do not automate operating-system configuration.
D
Distractor review
A proximity placement group for the VM
Proximity placement groups influence placement and latency, not software installation.
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: A Custom Script Extension on the VM — The Custom Script Extension is the right tool because it lets Azure run configuration commands after the VM is provisioned, which is exactly what is needed to install IIS and launch the registration script. When combined with a managed identity on the VM, the script can authenticate to Azure or internal services without embedded credentials. In Bicep, this can be fully automated and repeated on every deployment. Why others are wrong: A resource lock blocks management operations but does not perform configuration. An availability set only addresses resilience, not software setup. A proximity placement group may reduce latency between resources, but it has no role in post-deployment scripting or managed-identity-based registration logic.
