A few more sample questions
Sample question 1. An Azure DevOps Services organization uses the Agile system process. Support leads want a required Customer Impact picklist on the Bug work item type in one project only, without changing any other project. What should the administrator do?
- Edit the Agile system process, add the field to Bug, and hide it from the other projects with permissions
- Export the Bug type definition as XML, add the field, and import it back with witadmin importwitd
- Create an inherited process from Agile, add the field to Bug, then move only this project to it
- Add the field on the team settings page for the Bug backlog level of that project
Sample question 2. A repository requires code owner review on main. CODEOWNERS contains, in order: "* @org/leads", then "/infra/terraform/ @org/platform", then "*.tf @org/network". Pull requests that change /infra/terraform/vpc.tf are reviewed only by the network team, but the platform team must own everything under /infra/terraform/, including .tf files, while network keeps .tf files elsewhere. How should the file be fixed?
- Add @org/platform to the *.tf line, so that both the network and platform teams own every Terraform file in the repository
- Move the /infra/terraform/ line below the *.tf line, so it is the last pattern that matches files in that folder
- Move the "* @org/leads" line to the bottom of the file, so the default owner is checked last and settles every conflict
- Change "/infra/terraform/" to "/infra/terraform/**" in place, because patterns without a double asterisk do not match nested files
Sample question 3. A workflow only creates issues when a build fails, but its GITHUB_TOKEN carries broader access than needed. How should the permissions be reduced?
- Replace GITHUB_TOKEN with a classic personal access token with repo scope
- Set a permissions key in the workflow or job granting only issues: write
- Store GITHUB_TOKEN in a repository secret and reference it from there on each run
- Give each workflow file a unique name so that the tokens issued to them are distinct
