A developer is creating an application that is based on an AWS Lambda function. The function uses the AWS SDK to read product price data from an Amazon S3 bucket and to write user information to an Amazon Aurora DB instance The Lambda function runs often, up to a few times each minute To meet performance requirements, the developer must minimize the run duration of the Lambda function Which actions can help the developer increase the performance? (Select TWO)

• A.Use environment variables to pass operational parameters to the function.
• B.Read the S3 product price data initially and cache it locally in the /imp directory
• C.Split the code into different Lambda functions to keep the functions smaller
• D.Initialize SDK clients and database connections outside of the function handler
• E.Use most-restrictive permissions when setting the 1AM policies for the Lambda 1AM role

A company is using AWS CodePipeline to deliver one of its applications. The delivery pipeline is triggered by changes to the master branch of an AWS CodeCommit repository and uses AWS CodeBuild to implement the test and build stages of the process and AWS CodeDeploy to deploy the application.
The pipeline has been operating successfully for several months and there have been no modifications.
Following a recent change to the application's source code, AWS CodeDeploy has not deployed the updates application as expected.
What are the possible causes? (Choose two.)

• A.The AWS CodePipeline is incorrectly configured and is not executing AWS CodeDeploy.
• B.One of the Amazon EC2 instances in the company's AWS CodePipeline cluster is inactive.
• C.One of the earlier stages in the pipeline failed and the pipeline has terminated.
• D.AWS CodePipeline does not have permissions to access AWS CodeCommit.
• E.The change was not made in the master branch of the AWS CodeCommit repository.

• B.Callaws s3 cp to upload the AWS SAM template to Amazon S3 Call aws lambda update-function-code to create the application.
• C.Create a ZIP package and upload it to Amazon S3 Callaws cloudfonnation create-stack to create the application
• D.Call sam package to create the deployment package Call sam deploy to deploy the package afterward
• E.Callaws cloudformation package to create the deployment package Call aws cloudformation deploy to deploy the package afterward.

A Developer must re-implement the business logic for an order fulfilment system. The business logic has to make requests to multiple vendors to decide where to purchase an item. The whole process can take up to a week to complete.
What is the MOST efficient and SIMPLEST way to implement a system that meets these requirements?

• A.Use AWS Step Functions to execute parallel Lambda functions, and join the results.
• B.Create an AWS SQS for each vendor, poll the queue from a worker instance, and joint the results.
• C.Use AWS Lambda to asynchronously call a Lambda function for each vendor, and join the results.
• D.Use Amazon CloudWatch Events to orchestrate the Lambda functions.
