A company has a website that displays a daily newsletter. When a user visits the website, an AWS Lambda function processes the browser's request and queries the company's on- premises database to obtain the current newsletter. The
newsletters are stored in English. The Lambda function uses the Amazon Translate TranslateText API operation to translate the newsletters and the translation is displayed to the user.
Due to an increase in popularity, the website's response time has slowed. The database is overloaded The company cannot change the database and needs a solution that improves the response time of the Lambda function.
Which solution meets these requirements?
A. Change to asynchronous Lambda function invocation
B. Cache the translated newsletters in the Lambda /tmp directory
C. Enable TranslateText API caching.
D. Change the Lambda function to use parallel processing

Which solution will meet these requirements?
A. Amazon CloudFront
B. Amazon ElastiCache for Memcached
C. Amazon ElastiCache for Redis in cluster mode
D. Amazon DynamoDB Accelerator (DAX)

A company has a web application that runs on Amazon EC2 instances with a custom Amazon Machine Image (AMI) The company uses AWS CloudFormation to provision the application. The application runs in the us-east-1 Region, and the
company needs to deploy the application to the us-west-1 Region.
An attempt to create the AWS CloudFormation stack in us-west-1 fails An error message states that the AMI ID does not exist A developer must resolve this error with a solution that uses the least amount of operational overhead.
Which solution meets these requirements?
A. Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI Relaunch the stack for both Regions
B. Copy the custom AMI from us-east-1 to us-west-1 Update the AWS CloudFormation template for us- west-1 to refer to AMI ID for the copied AMI. Relaunch the stack.
C. Build the custom AMI in us-west-1 Create a new AWS CloudFormation template to launch the stack in us-west-1 with the new AMI ID
D. Manually deploy the application outside AWS CloudFormation in us-west-1
A developer has created a Java application that runs on AWS Elastic Beanstalk with the default Elastic Beanstalk instance profile. The developer needs to visualize a map of the application's interactions with AWS services to help identify and debug issues with the application.
