   A company runs a global application on EC2 instances behind an Application Load Balancer in multiple regions. They need to run a performance test that simulates user traffic from different geographical locations to ensure low latency. The test must be part of the CI/CD pipeline. What is the most effective way to generate this traffic?

   • AUse a distributed load testing tool, such as Apache JMeter running on EC2 instances in multiple regions.
   • BUse a single EC2 instance in the same region as the application to generate all the traffic.
   • CUse AWS CloudFront to cache the application and test the edge locations.
   • DUse AWS Device Farm to run the test from real mobile devices in different locations.

   A development team is building a CI/CD pipeline for a microservices application. They want to provide the fastest possible feedback to developers on code changes while keeping the pipeline efficient. The team has a suite of unit tests that run in under 2 minutes, integration tests that require a database and take 15 minutes, and end-to-end UI tests that take 40 minutes. Which testing strategy should the team implement?

   • ARun all test suites sequentially in the same pipeline stage after deployment to a staging environment.
   • BRun integration tests on every commit and unit tests only on pull request creation to prioritize database-related issues.
   • CRun only the UI tests on every commit because they provide the most comprehensive validation of the application.
   • DRun unit tests on every commit, integration tests on pull request creation, and UI tests only on merges to the main branch.

   A team is using CodeBuild to run a test script that outputs a JUnit XML report. They want the build to be marked as FAILED if any test in the report fails. The test script itself exits with a 0 exit code regardless of the test results. What should the team do?

   • AConfigure CodeBuild to parse the JUnit XML report and fail the build if tests fail.
   • BIgnore the exit code and manually review the test report after the build.
   • CUse a post-build action in CodePipeline to check the test report and fail the pipeline.
   • DModify the test script to exit with a non-zero code if any test fails.
