CCSP Cloud Platform and Infrastructure Security Practice Question
A serverless function needs to access a private database service without traversing the public internet. Which configuration should be used?
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
✓
Configure the serverless function with virtual private cloud integration
Virtual private cloud (VPC) integration allows the serverless function to be deployed inside a VPC, enabling private access to resources like a database service. Internet access is not required.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assign a public IP to the serverless function
Why it's wrong here
Assigning a public IP address does not provide private network access and still exposes the function to the internet.
- ✓
Configure the serverless function with virtual private cloud integration
Why this is correct
VPC deployment places the function within the VPC, allowing it to access private resources like a database instance directly.
- ✗
Enable public access on the database service
Why it's wrong here
Enabling public access would expose the database to the internet, defeating the security requirement.
- ✗
Use a network address translation gateway to route traffic
Why it's wrong here
A NAT gateway provides outbound internet access, not private inbound access to a database within the VPC.
