A company has an application that is deployed on AWS Elastic Beanstalk. The application generates user-specific PDFs and stores the PDFs in an Amazon S3 bucket. The application then uses Amazon Simple Email Service (Amazon SES) to send the PDFs by email to subscribers. Users no longer access the PDFs 90 days after the PDFs are generated. The S3 bucket is not versioned and contains many obsolete PDFs. A developer must reduce the number of files in the S3 bucket by removing PDFs that are older than 90 days. Which solution will meet this requirement with the LEAST development effort?

A company has an analytics application that uses an AWS Lambda function to process transaction data asynchronously A developer notices that asynchronous invocations of the Lambda function sometimes fail When failed Lambda function invocations occur, the developer wants to invoke a second Lambda function to handle errors and log details.

Which solution will meet these requirements?

A.
Configure a Lambda function destination with a failure condition Specify Lambda function as the destination type Specify the error-handling Lambda function's Amazon Resource Name (ARN) as the resource

Configure a Lambda function destination with a failure condition Specify Lambda function as the destination type Specify the error-handling Lambda function's Amazon Resource Name (ARN) as the resource
B.
Enable AWS X-Ray active tracing on the initial Lambda function. Configure X-Ray to capture stack traces of the failed invocations. Invoke the error-handling Lambda function by including the stack traces in the event object.

D.
Create a status check alarm on the initial Lambda function. Configure the alarm to invoke the error-handling Lambda function when the alarm is initiated. Ensure that the alarm passes the stack trace in the event object.
Answers
D.
Create a status check alarm on the initial Lambda function. Configure the alarm to invoke the error-handling Lambda function when the alarm is initiated. Ensure that the alarm passes the stack trace in the event object.
Suggested answer: A

Explanation:

Lambda Destinations on Failure:Allow routing asynchronous function invocations to specified resources (like another Lambda function) upon failure.

Error Handling:The error-handling Lambda receives details about the failure, enabling logging and custom actions.

Direct Integration:This solution leverages native Lambda functionality for a simpler implementation.
