Exam Preparation Quiz

Explanations for each answer:

• Configure a branch policy for the feature branches is incorrect. Configuring branch policies on feature branches would not enforce the code coverage requirements when merging into the main branch, as the policy needs to be on the target branch (main) which receives the pull request.
• Configure a branch policy for the main branch is correct. Branch policies on the main branch can enforce code coverage requirements for incoming pull requests. By setting up a branch policy with a required build that includes code coverage checking, you can block pull requests that don't meet the 90% coverage threshold.
• Create a code coverage configuration YAML file is incorrect. Azure DevOps doesn't use a separate code coverage configuration YAML file to enforce code coverage thresholds on pull requests. Code coverage settings are typically configured within the build pipeline YAML and enforced through branch policies.
• Create a Publish Test Results task is incorrect. While a Publish Test Results task can publish code coverage data, it only makes the results visible in the pipeline. It doesn't enforce a minimum threshold for pull request acceptance. Branch policies are needed to block merges that don't meet requirements.
