- A
Place the Functions in Azure API Management and configure IP restrictions.
Why wrong: API Management is not required for VNet access.
- B
Configure IP address restrictions on the Function App to allow only the VNet's public IP range.
Why wrong: IP restrictions are less secure and not dynamic.
- C
Deploy the Function App in a Premium plan and configure VNet integration, then use a Network Security Group to restrict traffic.
VNet integration allows the function app to access resources in the VNet and restrict inbound traffic.
- D
Configure a private endpoint for the Function App and disable public access.
Why wrong: Private endpoint is for inbound access; VNet integration is for outbound. Both can be used but VNet integration is the correct approach for access from the VNet.
AZ-204 Implement Azure security Practice Question
This AZ-204 practice question tests your understanding of implement azure security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are developing a serverless API using Azure Functions. The API should only be accessible from a specific virtual network. You need to configure network security. What should you do?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Deploy the Function App in a Premium plan and configure VNet integration, then use a Network Security Group to restrict traffic.
Azure Functions Premium plan supports VNet integration. You can enable VNet integration and then use network security groups (NSG) or service endpoints to restrict access. Option C is correct. Option A is wrong because Azure API Management is a separate service. Option B is wrong because App Service access restrictions can be used but VNet integration is more appropriate. Option D is wrong because private endpoints are for inbound access from a VNet, but Functions Premium also supports VNet integration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
