NEW QUESTION 1
What should you use to implement the code quality restriction on the release pipeline for the investment planning applications suite?

• A. a trigger
• B. a pre deployment approval
• C. a post-deployment approval
• D. a deployment gate

Answer: B

Explanation:
When a release is created from a release pipeline that defines approvals, the deployment stops at each point where approval is required until the specified approver grants approval or rejects the release (or re-assigns the approval to another user).
Scenario: Code quality and release quality are critical. During release, deployments must not proceed between stages if any active bugs are logged against the release. References: https://docs.microsoft.com/enus/ azure/devops/pipelines/release/approvals/approvals

Explanation:
In some cases, you need to bypass policy requirements so you can push changes to the branch directly or complete a pull request even if branch policies are not satisfied. For these situations, grant the desired permission from the previous list to a user or group. You can scope this permission to an entire project, a repo, or a single branch. Manage this permission along the with other Git permissions. References: https://docs.microsoft.com/en-us/azure/devops/repos/git/branchpolicies
