XK0-005 Question #1319: Real Exam Question with Answer & Explanation

Question

An administrator is trying to optimize a connection to an off-site NFS server. Which of the following commands would BEST display the problems with packet sizes between hops on the network?

Options

• Atracepath
• Bping
• Ctracert
• Dnmap

Explanation

The tracepath command is ideal for displaying network path information and detecting issues related to Maximum Transmission Unit (MTU) or packet sizes between hops.

Common mistakes.

• B. The ping command tests basic connectivity and latency but does not provide detailed information about packet sizes or MTU issues along the network path.
• C. The tracert (or traceroute) command displays the route packets take to a host and measures transit delays, but it does not inherently focus on or display packet size or MTU problems.
• D. The nmap command is a network scanner used for host discovery and port scanning, not for analyzing packet sizes or MTU issues on a network path.
