Question

Your network contains an on-premises Active Directory domain. The domain contains two computers named Computer1 and Computer2 that run Windows 10. You install Windows Admin Center on Computer1. You need to manage Computer2 from Computer1 by using Windows Admin Center. What should you do on Computer2?

Options

  • AUpdate the TrustedHosts list.
  • BRun the Enable-PSRemoting cmdlet.
  • CAllow Windows Remote Management (WinRM) through the Microsoft Defender firewall.
  • DAdd an inbound Microsoft Defender Firewall rule.

Explanation

The correct answer is C - Allow Windows Remote Management (WinRM) through the Microsoft Defender Firewall. Windows Admin Center communicates with managed nodes over WinRM (ports 5985/5986). For Computer1 to manage Computer2, the Defender Firewall on Computer2 must permit inbound WinRM traffic. Option A (updating TrustedHosts) is performed on the source/management machine (Computer1) when connecting with local accounts, not on the target. Option B (Enable-PSRemoting) enables PowerShell remoting but in a domain environment WinRM service may already be running - the firewall rule is the specific blocker. Option D is similar to C but refers to manually adding a custom rule, while C describes the simpler, built-in method of allowing the predefined WinRM rule.
