What does the ping command primarily help you determine?

• A. Whether you can reach a resource and the latency in milliseconds.
• B. The amount of data that can be transferred per second.
• C. Whether DNS resolution is successful.
• D. The OS version on the remote host.

Answer: (A)

Ping tests connectivity and measures how long it takes for a message to travel to a host and back. It does this by sending an ICMP Echo Request and waiting for an ICMP Echo Reply; when a reply arrives, you see the round-trip time in milliseconds, which is the latency. If replies fail or there’s packet loss, ping helps you diagnose network issues or a host/firewall blocking ICMP. This tool isn’t designed to gauge how much data you can transfer per second (throughput) or to confirm DNS resolution (that’s what DNS tools are for), and it doesn’t reveal the remote operating system. If you use a hostname, DNS resolution happens as part of the process, but the primary takeaway is whether the host is reachable and how responsive it is.
