Your company uses Azure DevOps for the build pipelines and deployment pipelines of Java-based projects.
You need to recommend a strategy for managing technical debt. Which action should you include in the recommendation?
- A. Configure post-deployment approvals in the deployment pipeline.
- B. Integrate Azure DevOps and Sonar Rube.
- C. Integrate Azure DevOps and Azure Dev Test Labs.
Answer: B
Explanation:
You can manage technical debt with Sonar Rube and Azure DevOps.
Note: Technical debt is the set of problems in a development effort that make forward progress on customer value inefficient. Technical debt saps productivity by making code hard to understand, fragile, time-consuming to change, difficult to validate, and creates unplanned work that blocks progress. Unless they are managed, technical debt can accumulate and hurt the overall quality of the software and the productivity of the development team in the long term
SonarQube an open source platform for continuous inspection of code quality to perform automatic reviews with static analysis of code to:
✑ Detect Bugs
✑ Code Smells
✑ Security Vulnerabilities
✑ Centralize Quality
✑ What’s covered in this lab

You need to implement the code flow strategy for Project2 in Azure DevOps.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange in the correct order.
Solution:
Step 1: Create a repository
A Git repository, or repo, is a folder that you've told Git to help you track file changes in. You can have any number of repos on your computer, each stored in their own folder.
Step 2: Create a branch
Branch policies help teams protect their important branches of development. Policies enforce your team's code quality and change management standards.
Step 3: Add a build validation policy
When a build validation policy is enabled, a new build is queued when a new pull request is created or when changes are pushed to an existing pull request targeting this branch. The build policy then evaluates the results of the build to determine whether the pull request can be completed.
Scenario:
Implement a code flow strategy for Project2 that will: Enable Team2 to submit pull requests for Project2.
Enable Team2 to work independently on changes to a copy of Project2.
Ensure that any intermediary changes performed by Team2 on a copy of Project2 will be subject to the same restrictions as the ones defined in the build policy of Project2.
