Question 1

A Lambda function deployed in a VPC cannot reach an external AWS service endpoint. What is the most likely missing configuration?

Accepted Answer

VPC NAT Gateway or VPC endpoint for the target service is missing

Question 2

Which AWS service can be used to manage and deploy serverless applications shared in the AWS Serverless Application Repository?

Accepted Answer

AWS Serverless Application Repository with sar deploy

Answer

The AWS Serverless Application Repository allows teams to publish, share, and deploy serverless applications directly using the SAR console or API.

Question 3

What is the purpose of Lambda Destinations for asynchronous invocations?

Accepted Answer

To route success and failure results to services like SQS, SNS, or EventBridge without custom code

Answer

Lambda Destinations automatically send the result of asynchronous invocations to a configured target service on success or failure, replacing the need for custom error-handling code.

Question 4

In a SAM template, the Globals section is used to define shared settings. Which of the following properties CANNOT be set in Globals?

Accepted Answer

FunctionName

Answer

FunctionName is resource-specific and cannot be defined in the Globals section; properties like Timeout, MemorySize, and Environment variables can be shared globally.

Question 5

A DevOps engineer needs Lambda function logs to be exported to an S3 bucket for long-term storage. What is the correct approach?

Accepted Answer

Create a CloudWatch Logs subscription filter that streams to Kinesis Firehose and then S3

Answer

CloudWatch Logs subscription filters can stream log data to Kinesis Data Firehose, which then delivers the logs to S3 for archival.
