AZ400-Q: trigger a trusted external integration
A work-management system must react when a pull request is merged. What is the right integration pattern?
- A) Share an administrator password with the system.
- B) Poll public screenshots of the repository.
- C) Use a personal access token embedded in client code.
- D) Configure a signed/authenticated webhook with the minimum events and verify it at the receiver. ✓ Answer: D. Webhooks provide event-driven integration; authentication and verification protect the boundary. Why not the others: Shared credentials, scraping, and exposed tokens are unsafe or unreliable.
