CCNA: Cisco Certified Network Associate — Question 92
Which device performs stateful inspection of traffic?
Answer options
- A. switch
- B. firewall
- C. access point
- D. wireless controller
Correct answer: B
Explanation
The correct answer is B, as firewalls are specifically designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. In contrast, switches primarily manage data traffic within a local area network, access points provide wireless connectivity, and wireless controllers oversee multiple access points but do not perform traffic inspection.
