A mobile application is developed for both iOS and Android. The application uses a shared codebase with platform-specific modules for device features. The test team needs to verify that the application can be installed and run on a new Android device model that has a different screen resolution and a newer version of the operating system. What should the test team do?

Review the platform-specific modules to ensure they are compatible with the new OS version.

Perform installability and adaptability tests on the new device model, including installation, launch, and core functionality checks.

Test the application only on the iOS version, as the shared codebase ensures identical behavior.

Only perform installability tests, as the application is already known to work on Android.

A web application is designed to run in different web browsers, including Chrome, Firefox, and Safari. The application uses standard HTML, CSS, and JavaScript. The test team needs to verify that the application's core functionality works consistently across all three browsers. What is the most efficient testing approach?

Test the application only in Chrome, as it is the most widely used browser.

Review the HTML, CSS, and JavaScript code to ensure it is standards-compliant.

Execute a core set of functional test cases in each of the three browsers and compare the results.

Test the application in Chrome and Firefox, and assume it will work in Safari.

A software product is distributed as a ZIP file that must be extracted and run. The test team must verify that the product can be installed and run on a new server that has a different operating system version and a different Java runtime. What is the most important testing activity?

Extract the ZIP file on the new server, run the product, and verify it starts and functions correctly.

Test the product on the old server and assume it will work on the new server.

Verify that the product can be adapted to the new Java runtime by changing its configuration.

Review the product's documentation to confirm it supports the new operating system and Java runtime.

A software company is releasing a new version of its application that includes a major database schema change. The test team must verify that the upgrade from the previous version preserves all existing data and that the application functions correctly after the upgrade. The upgrade process is complex and must be tested thoroughly. What is the most critical testing activity?

Perform an upgrade test on a copy of the production database, verifying data integrity and application functionality after the upgrade.

Review the database migration scripts to ensure they are correct.

Perform a replaceability test by comparing the old and new versions' features.

Perform a clean installation of the new version and verify it starts successfully.
