In PowerShell, how can you check the connectivity of multiple ports on a specific IP address?

• A. By using the Test-Port command
• B. By implementing a for loop
• C. By utilizing the Test-NetConnection command
• D. By employing the Connect-Computer command

Answer: (C)

Utilizing the Test-NetConnection command is an effective way to check the connectivity of multiple ports on a specific IP address in PowerShell. This command allows users to determine the connectivity status of a remote host and can specifically test various TCP ports. By using the `-Port` parameter, you can specify the port number(s) you want to check against the target IP address. It provides detailed output regarding the connection attempt, helping users diagnose network issues or verify open ports on remote systems. For instance, when checking multiple ports, you could use a loop along with Test-NetConnection to iterate through a list of ports, but the command itself is designed specifically for testing connections, making it the preferred and more straightforward choice. Other methods such as the Connect-Computer command are not relevant for checking port connectivity since they are focused more on establishing sessions or connections to other computers rather than testing network ports.
