A systems administrator observes high latency values when reaching a remote web server. Which of the following commands will help determine and isolate issues on the network side?
The correct answer is A. mtr. To diagnose high latency to a remote web server and identify network issues, the mtr command is most effective as it combines the functionality of traceroute and ping.

Why each option
To diagnose high latency to a remote web server and identify network issues, the `mtr` command is most effective as it combines the functionality of `traceroute` and `ping`.
The `mtr` (My Traceroute) command continuously sends packets and displays statistics about the path to a destination, including latency and packet loss for each hop along the route. This provides a live, continuously updated view of network performance, making it highly effective for identifying specific segments or routers experiencing high latency or packet loss.
The `dig` command (Domain Information Groper) is used for querying DNS name servers and will not help in analyzing network latency or routing paths.
The `netstat` command displays network connections, routing tables, interface statistics, and multicast memberships, but it does not trace the path or provide hop-by-hop latency statistics to a remote host.
The `route` command displays or modifies the IP routing table on the local system, which is useful for understanding local routing but not for diagnosing latency across the entire path to a remote server.
