Question 68

A developer has created a large AWS Lambda function. Deployment of the function Is failing because of an InvalidParameterValueException error. The error message indicates that the unzipped size of the function exceeds the maximum supported value.

Which actions can the developer take to resolve this error? (Select TWO.)

Options:

Submit a quota increase request to AWS Support to increase the function to the required size.

Use a compression algorithm that is more efficient than ZIP.

Break up the function into multiple smaller functions.

Zip the .zip file twice to compress the file more.

Move common libraries, function dependencies, and custom runtimes into Lambda layers.

Question 69

A developer is using AWS Amplify Hosting to build and deploy an application. The developer is receiving an increased number of bug reports from users. The developer wants to add end-to-end testing to the application to eliminate as many bugs as possible before the bugs reach production.

Which solution should the developer implement to meet these requirements?

Options:

Run the amplify add test command in the Amplify CLI.

Create unit tests in the application. Deploy the unit tests by using the amplify push command in the Amplify CLI.

Add a test phase to the amplify.yml build settings for the application.

Add a test phase to the aws-exports.js file for the application.

Question 70

A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node is application. To minimize these bugs, the developer wants to impendent automated testing of Lambda functions in an environment that Closely simulates the Lambda environment.

The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (Ct/CO) pipeline before the AWS Cloud Development Kit (AWS COK) deployment.

Which solution will meet these requirements?

Options:

Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response Document the test scripts for the other developers on the team Update the CI/CD pipeline to run the test scripts.

Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda Documentation Invoke the handler function by using a unit testing framework. Check the response Document how to run the unit testing framework for the other developers on the team. Update the OCD pipeline to run the unit testing framework.

Install the AWS Serverless Application Model (AWS SAW) CLI tool Use the Sam local generate-event command to generate sample events for me automated tests. Create automated test scripts that use the Sam local invoke command to invoke the Lambda functions. Check the response Document the test scripts tor the other developers on the team Update the CI/CD pipeline to run the test scripts.

Create sample events based on the Lambda documentation. Create a Docker container from the Node is base image to invoke the Lambda functions. Check the response Document how to run the Docker container for the more developers on the team update the CI/CD pipeline to run the Docker container.

Question 71

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?

Options:

Update the application code. In the code, add a rule to scan all the objects in the S3 bucket every day and to delete objects after 90 days.

Create an AWS Lambda function. Program the Lambda function to scan all the objects in the S3 bucket every day and to delete objects after 90 days.

Create an S3 Lifecycle rule for the S3 bucket to expire objects after 90 days.

Partition the S3 objects with a // key prefix. Create an AWS Lambda function to remove objects that have prefixes that have reached the expiration date.
