   A team's pipeline has evolved over time, and the automated tests have become brittle, with many tests failing due to changes in the application's UI. The team wants to maintain the test automation suite effectively. Which practice best supports this?

   • AOnly run the test suite on a nightly basis to reduce the frequency of failures.
   • BDelete any test that fails more than once to keep the suite green.
   • CFreeze the test suite and do not change it unless a test fails in the pipeline.
   • DRegularly review and update test selectors and test data to align with the current application behavior, and track test maintenance as a backlog item.

   A team has a large suite of API tests that currently run sequentially in a single pipeline agent, taking 45 minutes. The team wants to reduce execution time by running tests in parallel. Which approach is most effective?

   • ASplit the test suite into smaller groups and distribute them across multiple pipeline agents, each with its own isolated test environment.
   • BIncrease the timeout for the single agent to allow the tests to run longer.
   • CRun the entire suite on multiple agents simultaneously, with each agent executing the same tests.
   • DUse a single agent but run tests in parallel threads within the same process.

   A team runs integration tests in a pipeline that requires a database with a large volume of realistic data. The tests are executed in parallel across multiple agents. The team is concerned about the time it takes to provision the database and load the data for each agent. Which strategy best reduces provisioning time while maintaining test reliability?

   • ALoad the data once into a central database and have all agents connect to it, using unique test data per agent.
   • BUse a single shared database for all parallel agents and rely on transactions to isolate test data.
   • CReduce the volume of test data to make loading faster, even if it reduces test coverage.
   • DCreate a database snapshot after the initial data load and restore it for each parallel agent before running tests.

   A company is adopting CI/CD for the first time. They currently run all tests manually after each release. They want to introduce automated tests into the pipeline to get faster feedback. Which initial step best aligns with CI/CD principles?

   • AKeep manual testing as the primary gate and add automated tests only for the final release.
   • BStart by automating a small set of high-value unit tests and run them on every commit to the main branch.
   • CAutomate all existing manual tests at once and run them in a nightly pipeline.
   • DRun automated tests only on a schedule, such as weekly, to avoid overloading the pipeline.
