GIAC Security Essentials Certification (GSEC) — Question 15

It is possible to sniff traffic from other hosts on a switched Ethernet network by impersonating which type of network device?

Answer options

• A. Switch
• B. Bridge
• C. Hub
• D. Router

Correct answer: D

Explanation

The correct answer is D, Router, because routers can be configured to monitor and manipulate traffic, allowing for packet sniffing. Switches and bridges do not typically allow traffic interception from other hosts due to their design, which directs traffic only to the intended recipient. Hubs are outdated and do not perform the same functions as a router.
