AZ-204 Develop Azure compute solutions Practice Question
This AZ-204 practice question tests your understanding of develop azure compute solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A image resize worker runs in Azure App Service and must call a private API hosted inside a virtual network. Which feature allows outbound access from the app to the VNet?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Regional VNet integration
Regional VNet integration enables an Azure App Service app to make outbound calls to resources in a virtual network (VNet) over the Microsoft backbone network. It uses a delegated subnet in the VNet to assign the app a network interface in the VNet, allowing it to reach private APIs without exposing them to the public internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Regional VNet integration
Why this is correct
Regional VNet integration enables App Service outbound connectivity to resources in a virtual network.

✗
Azure CDN custom domain
Why it's wrong here
CDN accelerates content delivery and does not provide VNet connectivity.
✗
Application Gateway path routing
Why it's wrong here
Application Gateway routes inbound traffic and does not give the app outbound VNet access.
✗
Private Endpoint for the web app only
Why it's wrong here
A Private Endpoint provides private inbound access to the web app, not outbound connectivity from it.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing inbound connectivity (Private Endpoint) with outbound connectivity (VNet integration), leading candidates to select Private Endpoint when the question asks for outbound access from the app to the VNet.
Detailed technical explanation
How to think about this question
Regional VNet integration works by creating a network interface in the delegated subnet for each App Service instance, using the Azure DNS resolution to resolve private IPs. The app's outbound traffic is routed through this interface, and you can force-tunnel traffic to on-premises via a VPN gateway if the subnet has a route table with a default route to the gateway. A common real-world scenario is a microservice architecture where a front-end app in App Service needs to call a backend API hosted on an internal load balancer in a VNet.
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.
TExam Day Tips
→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.
