A platform team is reviewing isolation controls for four parallel agent tasks. Match each isolation control to the risk it most directly reduces. Which mapping is correct?
1. PR-specific concurrency group
2. Matrix-scoped artifact names
3. Separate agent branches
4. Narrow MCP tool configuration
A. Evidence from separate agent scopes becomes mixed
B. One agent can overwrite another agent’s commits
C. Unneeded external tools are available to the agent
D. One agent PR cancels another agent PR run
E. GitHub-hosted runner image updates between executions
F. Draft pull requests require reviewer confirmationChoose an answer

Correct answer: 1-D, 2-A, 3-B, 4-C.
Why this is the answer
1-D: A PR-specific concurrency group ensures that only one workflow run for a given pull request can execute at a time, preventing a new run from canceling an in-progress one. 2-A: Matrix-scoped artifact names ensure that artifacts generated by different matrix jobs within the same workflow run are uniquely identified, preventing their evidence from being mixed or overwritten. 3-B: Separate agent branches ensure that each agent operates on its own isolated codebase, preventing one agent from inadvertently overwriting another agent's commits. 4-C: Narrowing the MCP (Managed Code Platform) tool configuration restricts the external tools available to an agent, reducing the risk of an agent accessing or using unneeded or unauthorized tools.
