A company hosts a monolithic application on Amazon EC2 instances. The company starts converting some features of the application to a serverless architecture by using Amazon API Gateway and AWS Lambda After the migration, some users report problems with payment processing Upon inspection, a developer discovers that the Lambda function that calls the external payment API is taking longer than expected Therefore, the API Gateway requests are timing out What should the developer do to resolve this issue in the serverless architecture?

• A.Increase the API Gateway timeout duration to match the payment API time
• B.Increase the Lambda function's memory to increase the network bandwidth and increase the speed of the payment API calls
• C.Use the EC2 instances to make the API calls to the payment API
• D.Use Amazon Simple Queue Service (Amazon SQS) with API Gateway and the Lambda function to asynchronously call the payment API

A company is adding items to an Amazon DynamoDB table from an AWS Lambda function that is written in Python A developer needs to implement a solution that inserts records in the DynamoDB table and performs automatic retry when the insert fails Which solution meets these requirements with MINIMUM code changes?

• A.Configure the Python code to run the AWS CLl through shell to call the Putltem operation
• B.Call the Putltem operation from Python by using the DynamoDB HTTP API
• C.Use the AWS software development kit (SDK) for Python (boto3) to call the Putltem operation
• D.Queue the items in AWS Glue: which will put them into the DynamoDB table

A Developer is writing an imaging micro service on AWS Lambd
a. The service is dependent on several libraries that are not available in the Lambda runtime environment.
Which strategy should the Developer follow to create the Lambda deployment package?

• A.Create a ZIP file with the source code and all dependent libraries.
• B.Create a ZIP file with the source code. Stage the dependent libraries on an Amazon S3 bucket indicated by the Lambda environment variable LD_LIBRARY_PATH
• C.Create a ZIP file with the source code and a buildspec.yaml file that installs the dependent libraries on AWS Lambda.
• D.Create a ZIP file with the source code and a script that installs the dependent libraries at runtime.

A Developer is creating a Lambda function and will be using external libraries that are not included in the standard Lambda libraries.
What action would minimize the Lambda compute time consumed?

• A.Copy the external libraries to Amazon S3, and reference the external libraries to the S3 location.
• B.Install the external libraries in Lambda to be available to all Lambda functions.
• C.Install the dependencies and external libraries at the beginning of the Lambda function.
• D.Create a Lambda deployment package that includes the external libraries.

A Developer must repeatedly and consistently deploy a serverless RESTful API on AWS.
Which techniques will work? (Choose two.)

• A.Define a Swagger file. Use AWS Elastic Beanstalk to deploy the Swagger file.
• B.Define a Swagger file. Use AWS CodeDeploy to deploy the Swagger file.
• C.Deploy a SAM template with an inline Swagger definition.
• D.Define a Swagger file. Deploy a SAM template that references the Swagger file.
• E.Define an inline Swagger definition in a Lambda function. Invoke the Lambda function.
