   A company is replacing a custom-built inventory management module with an off-the-shelf product. The custom module has a well-defined API that is used by several other internal applications. The test team must ensure that the new product can replace the custom module without breaking the dependent applications. What is the most important testing activity?

   • APerform replaceability testing by running the dependent applications against the new product's API and verifying they function correctly.
   • BPerform performance testing to ensure the new product can handle the expected load.
   • CPerform adaptability testing by verifying the new product can run on the company's existing servers.
   • DPerform installability testing by installing the new product on a test server and verifying it starts successfully.

   A company is replacing its legacy customer relationship management (CRM) system with a new off-the-shelf product. The test team must ensure that customer data from the legacy system can be migrated to the new system and that existing business processes can be performed without loss of functionality. Which testing activity is most important?

   • APerform a replaceability test by migrating a representative set of customer data and executing end-to-end business process tests.
   • BRun an adaptability test by changing the new CRM's configuration to match the legacy system's settings.
   • CConduct an installability test by installing the new CRM on a test server and verifying it starts successfully.
   • DExecute a performance test to ensure the new CRM can handle the expected user load.

   A software product is designed to run on both Windows Server and Red Hat Enterprise Linux. The product uses a configuration file that specifies file paths, database connection strings, and logging levels. The test team needs to verify that the product can run on both operating systems without requiring source code modifications. What is the most appropriate test approach?

   • AInstall the product on both operating systems and execute a core set of functional test cases to verify behavior is consistent.
   • BReview the source code to confirm that no platform-specific API calls are used.
   • CTest the product on one operating system and assume it will work on the other due to the configuration file.
   • DVerify that the product can be uninstalled cleanly from both operating systems.

   A financial services company is migrating its customer-facing web application from an on-premises Linux environment to a managed Kubernetes platform in a public cloud. The application is packaged as a container image and uses environment variables for configuration. The test team must verify that the application can be deployed successfully in the new environment without code changes. Which testing activity is most directly aligned with this objective?

   • AExecute an adaptability test by running the application with different environment variable values to confirm behavior changes as expected.
   • BRun a performance test to measure the application's response time under load in the Kubernetes cluster.
   • CConduct a replaceability test by comparing the application's output with the previous on-premises version to ensure functional parity.
   • DPerform an installability test by deploying the container to the Kubernetes cluster and verifying the application starts and responds to health checks.

   A company has a legacy desktop application that is being migrated to a web-based application. The web application must support both Chrome and Firefox, and the test team has limited time. The application uses a complex JavaScript library that is known to have some compatibility issues with Firefox. The test team must decide how to allocate testing effort. What is the most effective strategy?

   • APrioritize testing in Firefox, as it is known to have compatibility issues, and perform a smaller set of smoke tests in Chrome.
   • BTest only in Chrome, as it is the most popular browser.
   • CTest only in Firefox, as it is the higher-risk environment.
   • DTest equally in both Chrome and Firefox to ensure balanced coverage.
