A developer is launching a global application that delivers content to multiple countries. The developer needs to serve specific content based on the country of each user and each user's primary language. The developer must ensure that content is served reliably and with low latency.
Which solution will meet these requirements?

• A.Create an Amazon API Gateway REST API. Connect the REST API to AWS WAF. Use geo match statements and regex match statements to allow or deny requests based on the labels returned from web request evaluations.
• B.Configure an Amazon CloudFront distribution that uses the application as an origin. Configure the distribution to forward the Accept-Language header and the CloudFront-Viewer-Country header to the origin.
• C.Create an Amazon API Gateway REST API. Create an AWS Global Accelerator standard accelerator to resolve requests to the API. Configure endpoint groups on the accelerator. Attach listeners for each country and language.
• D.Store the content in a centralized Amazon S3 bucket. Enable S3 Transfer Acceleration on the bucket. Create an Amazon Route 53 hosted zone that includes the endpoint for the S3 bucket.
  Create records in Route 53 that use geoproximity and geolocation routing policies.

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?

• A.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.
• B.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.
• C.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.
• D.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.

A developer runs an application that displays scores for sports games on Amazon EC2 instances. The application uses a Redis client to retrieve the scores from an Amazon ElastiCache (Redis OSS) cluster.
The developer observes increased latency during operations on the cache because of connection failures to the cluster. The developer needs to resolve the latency issues.

• A.Configure the Redis client to use an exponential backoff retry strategy to establish cache connections.
• B.Store the scores in the application's memory. Perform bulk set operations on the scores that are stored in memory.
• C.Configure the Redis client in the application to persist connections to the cluster by implementing a connection pool.
• D.Deploy more nodes in the ElastiCache cluster. Update the Redis client to discover the new nodes.

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?

• A.Run the amplify add test command in the Amplify CLI.
• B.Create unit tests in the application. Deploy the unit tests by using the amplify push command in the Amplify CLI.
• C.Add a test phase to the amplify.yml build settings for the application.
• D.Add a test phase to the aws-exports.js file for the application.
