Which command would typically be used to check for network issues in DOS?

• A. PING
• B. CHECKNET
• C. NETTEST
• D. TRACEROUTE

Answer: (A)

Using the PING command is a standard method to check for network connectivity issues in DOS. When executed, PING sends Internet Control Message Protocol (ICMP) Echo Request messages to the specified IP address or hostname and listens for Echo Reply messages. This process helps determine if the target host is reachable over the network and measures the round-trip time for messages sent. It is particularly useful for diagnosing whether there are issues with network connectivity, latency, or packet loss. Other commands mentioned, such as CHECKNET and NETTEST, do not exist as built-in commands in DOS for troubleshooting network problems. While TRACEROUTE (or TRACERT in DOS) is indeed a command used to trace the route packets take to their destination, it serves a different purpose by providing details about the path taken rather than simply checking connectivity. Thus, PING stands out as the most straightforward and commonly used tool for quickly assessing network issues in a DOS environment.
