CompTIA Network+ (N10-007) — Question 556

A network technician is assisting a user who is having problems accessing a particular website. Other users are reporting that the website is accessible outside of the office. The technician suspects the problem is with the company's firewall. Which of the following should the technician use to troubleshoot?

Answer options

Correct answer: D

Explanation

The correct tool for troubleshooting potential firewall issues is a Packet sniffer, as it allows the technician to analyze network traffic and determine if packets are being blocked by the firewall. A WiFi analyzer and bandwidth speed tester are less relevant in this case, and while 'Dig' can be useful for DNS queries, it doesn't offer the insight needed to diagnose firewall-related problems.
