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

  1. A.Inspect client DNS server selection and AD SRV answers
  2. B.Treat successful ping by IP as proof AD DNS is healthy
  3. C.Flush every cache before checking which resolver answered
  4. D.Replace AD DNS with a public resolver as the default repair
  5. E.Compare relevant internal resolver responses and cached results
Show the answer and explanation

✓ Correct answers

  • Inspect client DNS server selection and AD SRV answers
  • Compare relevant internal resolver responses and cached results

Correct resolver selection, service records and response/cache comparison identify the failure. Public DNS cannot normally resolve private AD records; IP ping bypasses DNS; evidence should identify the resolver before blanket cache changes.
