Select all that apply. Every correct option and no extras are required for credit in the app.

  1. A.Assume forwarding always preserves the original client's source subnet
  2. B.Treat DNS weights as application health probes
  3. C.Account for caching when using weighted DNS answers
  4. D.Assume dynamic updates maintain every nondefault scope
  5. E.Keep appropriate default-scope answers for clients that do not match
Show the answer and explanation

✓ Correct answers

  • Account for caching when using weighted DNS answers
  • Keep appropriate default-scope answers for clients that do not match

Unmatched clients need suitable default behavior, and cached answers influence observed weight distribution. DNS weights do not provide application health probes. Dynamic updates apply to the default scope, and forwarding can make the authoritative server see the forwarder's source rather than the original client's subnet.
