CCSP Cloud Platform and Infrastructure Security Practice Question
An organization uses Azure Functions and needs to ensure that the function can securely access a database in a private VNet. What is the recommended approach?
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
✓
Enable VNet integration for the function app and configure the function to use the private IP of the database
VNet integration allows Azure Functions to access resources in a virtual network without exposing them to the internet, using a private IP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place the function in the same VNet as the database without any additional configuration
Why it's wrong here
Incorrect; Azure Functions by default are not injected into a VNet; explicit VNet integration is required.
- ✗
Use a VPN connection from the function to the database VNet
Why it's wrong here
Incorrect; VPN adds complexity and is not standard for Azure Functions.
- ✓
Enable VNet integration for the function app and configure the function to use the private IP of the database
Why this is correct
Correct; VNet integration provides private connectivity.
- ✗
Store database credentials in environment variables and use a public endpoint with IP whitelisting
Why it's wrong here
Incorrect; public endpoints are less secure; environment variables are not encrypted.
