Troubleshooting Network Connectivity on Linux Workstation

C.

The command that would help the technician gain information about the network settings on a Linux workstation is the ifconfig command.

The ifconfig command is used to configure and view the network interface parameters, such as IP address, netmask, and broadcast address. The command displays the current network configuration of all network interfaces on the system.

Here's what each of the other options listed would do:

• chmod is a command used to change the permissions of files or directories. It wouldn't be useful for troubleshooting network connectivity issues.
• grep is a command used to search for specific text patterns in files or output. While it could be used to search for network-related information, it wouldn't provide as comprehensive information as the ifconfig command.
• sudo is a command used to run other commands with administrative privileges. While it may be necessary for some troubleshooting tasks, it wouldn't provide information about the network settings on the machine.

Therefore, the correct answer is C. ifconfig.
