What command would you use to check the connectivity status to a remote host?

• A. uniq
• B. chmod
• C. kill
• D. ping

Answer: (D)

The command used to check the connectivity status to a remote host is "ping." This command sends Internet Control Message Protocol (ICMP) echo request packets to the target host and waits for a reply. When you execute the ping command followed by an IP address or hostname, it helps you determine if the remote host is reachable over the network. If the remote host responds, it confirms that the connection is active and the host is online. The output typically includes details such as the time taken for the round-trip and packet loss statistics, which are crucial for diagnosing network issues. In contrast, the other options do not relate to checking connectivity. The "uniq" command is utilized for filtering out repeated lines in text files. "chmod" is used to change the file permissions in Linux and UNIX systems, allowing users to set read, write, and execute permissions for files and directories. The "kill" command is employed to terminate processes in the operating system. Each of these commands serves a different purpose unrelated to network connectivity, making "ping" the appropriate choice for evaluating connectivity status.
