XK0-005 Question #101: Real Exam Question with Answer & Explanation

Question

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?

Options

• Amtr
• Bdig
• Cnetstat
• Droute

Explanation

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.

Common mistakes.

• B. The dig command (Domain Information Groper) is used for querying DNS name servers and will not help in analyzing network latency or routing paths.
• C. 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.
• D. 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.
