CompTIA Network+ (N10-007) — Question 302

A technician has been asked to diagnose problems with DHCP addressing on a VLAN. The DHCP server responds to pings from the technician's machine. Which of the following should the technician use to help diagnose the problem?

Answer options

• A. Packet sniffer
• B. netstat
• C. nslookup
• D. Spectrum analyzer

Correct answer: A

Explanation

A packet sniffer is the most effective tool for diagnosing DHCP issues as it captures and analyzes network traffic, allowing the technician to see DHCP requests and responses. netstat is used for viewing network connections and statistics, nslookup is for DNS queries, and a spectrum analyzer measures radio frequencies, making them less relevant for diagnosing DHCP problems.
