CCNA: Cisco Certified Network Associate — Question 989

What is a service that is provided by a wireless controller?

Answer options

• A. It mitigates threats from the internet.
• B. It manages interference in a dense network.
• C. It provides Layer 3 routing between wired and wireless devices.
• D. It issues IP addresses to wired devices.

Correct answer: B

Explanation

The correct answer is B, as a wireless controller is designed to manage and minimize interference in environments with many access points, ensuring optimal network performance. Option A is incorrect because threat mitigation is typically handled by firewalls or security appliances, not wireless controllers. Option C is not accurate because Layer 3 routing is generally performed by routers, not controllers. Option D is wrong since IP address assignment to wired devices is typically managed by DHCP servers, not wireless controllers.
