Question 1

Which AWS service allows you to define serverless workflows that orchestrate multiple Lambda functions with built-in error handling and retries?

Accepted Answer

AWS Step Functions

AWS Step Functions lets you coordinate Lambda functions and other services using state machines with configurable retry, catch, and parallel execution.

Question 2

What is the maximum deployment package size (unzipped) for a Lambda function deployed via the console or CLI?

Accepted Answer

250 MB

Answer

The maximum unzipped deployment package size for Lambda is 250 MB; the zipped package limit is 50 MB when uploading directly.

Question 3

A team wants to share common libraries across multiple Lambda functions without duplicating code in each package. What is the recommended approach?

Accepted Answer

Lambda layers

Answer

Lambda layers allow you to package shared libraries or runtimes and attach them to multiple functions, reducing deployment package size and duplication.

Question 4

In AWS CDK, which construct level is best suited for deploying a pre-built Lambda function with sensible defaults for a DevOps pipeline?

Accepted Answer

L2 (Function)

Answer

L2 constructs like aws_lambda.Function provide high-level abstractions with secure defaults, making them ideal for standard Lambda deployments in a pipeline.

Question 5

A Lambda function behind an API Gateway endpoint is experiencing throttling. Which metric in CloudWatch indicates requests are being rejected due to concurrency limits?

Accepted Answer

Throttles

Answer

The Throttles metric counts the number of invocation requests that Lambda rejected because the function reached its concurrency limit.
