In an FCIP environment where data replication is occurring between two FC SANs communication errors are becoming persistent, and occasionally the link drops. Which of the following would a technician

`ping` tests IP network reachability and latency, which is part of FCIP, but does not directly indicate Fibre Channel protocol-level link drops or specific FC issues.

`tracert` (traceroute) traces the IP path packets take, which is useful for identifying routing issues but not specifically designed to monitor Fibre Channel link drops within an FCIP tunnel.

`nslookup` is a utility used for querying the Domain Name System (DNS) to resolve hostnames to IP addresses, and it is irrelevant for diagnosing network link drops or FCIP connectivity issues.

`fcping` is a Fibre Channel specific utility that functions similarly to `ping` for IP networks, but it tests reachability and latency across Fibre Channel fabrics, including over FCIP tunnels. It can effectively diagnose and monitor Fibre Channel connectivity and link stability at the FC protocol layer, making it ideal for detecting FCIP link drops.
