CompTIA Linux+ (XK0-004) — Question 193

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?

Answer options

• A. mtr
• B. dig
• C. netstat
• D. route

Correct answer: A

Explanation

The command 'mtr' combines the functionality of 'ping' and 'traceroute', making it ideal for diagnosing network issues by showing the route packets take and the latency at each hop. 'dig' is used for DNS lookups, 'netstat' displays active connections and listening ports, and 'route' shows the routing table, but none of these specifically isolate latency issues like 'mtr' does.
