Question 1

Which antenna type radiates power equally in all horizontal directions, making it ideal for general-coverage deployments?

Accepted Answer

Omnidirectional antenna

Answer

Omnidirectional antennas radiate power in a 360-degree horizontal pattern, providing uniform coverage in all directions around the antenna.

Question 2

What is the primary function of a wireless LAN controller (WLC) in a centralized architecture?

Accepted Answer

Centrally manage and control lightweight access points

Answer

A WLC centrally manages lightweight APs by handling configuration, firmware updates, RF management, and client roaming in a CAPWAP-based architecture.

Question 3

A PoE switch port is rated at 802.3af. What is the maximum power it can deliver to a connected access point?

Accepted Answer

15.4 watts

Answer

IEEE 802.3af (PoE) delivers a maximum of 15.4 watts at the power-sourcing equipment (PSE) port, with up to 12.95 watts available at the powered device.

Question 4

What component in an access point converts the digital baseband signal into an RF signal for transmission?

Accepted Answer

Radio frequency transceiver

Answer

The RF transceiver (radio) modulates the digital baseband signal onto a carrier frequency and demodulates received RF signals back to digital data.

Question 5

Which hardware component is responsible for managing the RF environment by dynamically adjusting AP power and channel settings?

Accepted Answer

Wireless LAN controller with RRM

Answer

Radio Resource Management (RRM) is a WLC feature that automatically optimizes channel assignments and transmit power to minimize interference and maximize coverage.
