An AWS Lambda function attached to a VPC can reach a database in its own subnet but cannot reach a public internet API. Which configuration should you check first?
Subnet route table configuration
Security group rules
VPC peering issues
Network ACL settings
A
VPC-attached Lambda functions have no public IP address, so internet traffic must go through a NAT gateway, and the subnet's route table must send 0.0.0.0/0 to it. Security groups and network ACLs would also block the database if they were wrong, and VPC peering does not provide internet access.

About this course

Want to prove you really know AWS Lambda, for a job interview, a developer role or AWS certification study? This course gives you 5 practice tests with 411 questions covering the whole service: runtimes and event sources, packaging and IAM, CloudWatch and X-Ray, concurrency and cold starts, and AWS SAM, Step Functions, Lambda@Edge and VPC networking. Every question explains why the correct answer is right and why the other options are wrong.

Each test focuses on one area and has 76 to 90 questions, with an 80% pass mark and a hint on every question. The question set was reviewed in October 2026: duplicate questions were removed, answer keys were re-checked, and outdated advice such as VPC cold-start penalties was brought up to date. A printable 28-page cheat sheet and study guide is included.
