A team's CI pipeline has a high failure rate, and the team suspects that the failures are caused by flaky tests. The team has limited parallel agents and wants to reduce the impact of flaky tests on the pipeline without hiding real failures. What should you do?

Delete the flaky tests from the test suite.

Increase the number of parallel agents to run the tests more often.

Set the pipeline to continue on error for all test failures.

Identify the flaky tests by analyzing test results over time and then quarantine them in a separate, non-blocking job.

Your CI pipeline runs unit tests and integration tests sequentially. The unit tests take 5 minutes, and the integration tests take 15 minutes. The integration tests require a database that is provisioned in the pipeline. You want to reduce the overall pipeline duration without sacrificing test coverage. What should you do?

Use a multi-job pipeline to run unit tests and integration tests in parallel on separate agents.

Increase the timeout for the integration tests to allow more time for the database provisioning.

Move the integration tests to a separate pipeline triggered after the unit tests succeed.

Run the unit tests and integration tests in parallel on the same agent.

Your team needs to retain build artifacts for 30 days for debugging, but compliance requires keeping release artifacts for 7 years. You want to implement a retention strategy that meets both requirements without manual intervention. What should you do?

Disable retention for build artifacts and keep release artifacts for 7 years.

Set build pipeline retention to 30 days and release pipeline retention to 7 years.

Set a single retention policy for all pipelines to 7 years.

Manually delete build artifacts after 30 days and keep release artifacts for 7 years.
