Practice question 412 of 506 · medium

An operator must query files.contoso.com against DNS server 10.0.0.10 without LLMNR fallback. Which command fits?

Choose the single best answer.

  1. A.Clear-DnsClientCache as the query operation
  2. B.Resolve-DnsName files.contoso.com -Server 10.0.0.10 -DnsOnly
  3. C.Test-NetConnection files.contoso.com -Port 445 only
  4. D.Resolve-DnsName files.contoso.com without selecting the server or excluding fallback
Show the answer and explanation

✓ Correct answer

  • Resolve-DnsName files.contoso.com -Server 10.0.0.10 -DnsOnly

Resolve-DnsName with Server and DnsOnly selects the stated resolver and excludes LLMNR/NetBIOS resolution. The unqualified query does not enforce those choices. A TCP test does not isolate that DNS reply, and clearing cache does not query the specified resolver.
