What is the maximum execution timeout for an AWS Lambda function?

15 minutes (900 seconds). If a function needs to run longer, you must use a different compute service like ECS or EC2.

What is the maximum amount of memory you can allocate to a single Lambda function?

10,240 MB (10 GB). Memory allocation also proportionally increases the vCPU available to the function.

What is a Lambda 'cold start' and when does it occur?

A cold start is the initialization delay that occurs when Lambda must provision a new execution environment for a function invocation, typically after a period of inactivity or when scaling out.

What is the maximum unzipped deployment package size for a Lambda function?

250 MB. For larger dependencies, you should use Lambda Layers or load assets from S3 at runtime.

Which Lambda feature allows you to run code without packaging dependencies into the main deployment artifact, and can be shared across multiple functions?

Lambda Layers. A layer is a ZIP archive containing libraries or custom runtimes, and up to 5 layers can be attached to a single function.
