Practice question 408 of 506 · medium

Test-NetConnection shows TCP 3389 fails to an Azure VM. Which investigation fits?

Choose the single best answer.

  1. A.Effective NSG/routes plus guest RDP listener and firewall
  2. B.Only the VM Running state as proof the RDP service listens
  3. C.Only DNS success as proof every network and guest rule permits RDP
  4. D.Only a successful ICMP ping as proof TCP 3389 is allowed
Show the answer and explanation

✓ Correct answer

  • Effective NSG/routes plus guest RDP listener and firewall

TCP RDP depends on Azure controls, routing, and guest listener/firewall. Ping checks ICMP, Running reports VM state, and DNS supplies an address; none alone proves the specific RDP flow is allowed and accepted.
