Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Store database credentials in the function code
Why it's wrong here
Credentials management is separate; this does not solve network access.
- ✗
Use a NAT Gateway to allow inbound traffic
Why it's wrong here
NAT gateway is for outbound, not inbound to VPC.
- ✓
Place the Lambda function inside the VPC using VPC configuration
Why this is correct
Lambda VPC integration allows the function to access VPC resources privately.
- ✗
Attach an Internet Gateway to the VPC
Why it's wrong here
Internet gateway exposes to internet, not needed.
