Practice question 331 of 400 · hard

A subnet has applicable UDR, BGP, and system routes for the same destination prefix. No service-specific exception applies. Which route ordinarily takes precedence?

Choose the single best answer.

  1. A.The user-defined route
  2. B.The system route because all default routes are immutable
  3. C.The route with the highest numeric NSG priority
  4. D.The BGP route because dynamic routes always beat UDRs
Show the answer and explanation

✓ Correct answer

  • The user-defined route

For equal applicable prefixes, ordinary precedence is UDR, BGP, then system. Dynamic routing is not universally first, system routes can often be overridden by supported UDRs, and NSG priority selects filtering rules rather than routes. Source guide: PDF page(s) 57.
