AWS Serverless and Lambda Architecture 2

Question 1

What is the maximum deployment package size for a Lambda function uploaded directly (not via S3)?

Accepted Answer

50 MB

Answer

Lambda allows a maximum direct upload package size of 50 MB; larger packages must be uploaded via Amazon S3.

Question 2

Which invocation type causes Lambda to process events asynchronously and retry automatically on failure?

Accepted Answer

Asynchronous invocation

Answer

Asynchronous invocation places the event in an internal queue and Lambda retries failed executions up to two additional times.

Question 3

A company wants to run serverless container workloads without managing servers. Which AWS service should they use?

Accepted Answer

AWS Fargate

Answer

AWS Fargate is a serverless compute engine for containers that removes the need to provision or manage EC2 instances.

Question 4

Which AWS Lambda resource-based policy feature controls which AWS services or accounts can invoke your function?

Accepted Answer

Resource policy

Answer

A Lambda resource-based policy (function policy) grants permissions to other AWS accounts or services to invoke the function.

Question 5

What happens when a Lambda function's reserved concurrency is set to 0?

Accepted Answer

The function is throttled and cannot be invoked

Answer

Setting reserved concurrency to 0 effectively throttles the function, preventing any invocations.
