Which command is commonly used to test connectivity to a specific IP address?

• A. trace
• B. ping
• C. connect
• D. check

Answer: (B)

The command that is commonly used to test connectivity to a specific IP address is "ping." This command sends Internet Control Message Protocol (ICMP) echo request packets to the target IP address and waits for echo reply packets. By measuring the time it takes to receive the replies, users can determine if there is a connection to the target device and assess the round-trip time for packets. Using the ping command helps network administrators and users to troubleshoot and diagnose network issues. If the target device is reachable, it will respond with the time it took for each packet to make the round trip, indicating that the connection is active. In contrast, "trace" would typically refer to the traceroute command, which traces the path that packets take to reach the destination but does not merely test for connectivity. The terms "connect" and "check" do not correspond to standard networking commands used for testing address reachability and are not recognized commands in network troubleshooting contexts. Hence, the selected command, "ping," is the most appropriate and widely used command to verify connectivity to a specific IP address.
