Pearson CWDP-305 New Attempt

Once the WLAN is validated and operational, the next step is knowledge transfer. Support staff must be trained on monitoring, troubleshooting, and configuration, while end-users benefit from understanding basic usage and policies. Executives and guests are not directly involved in daily operations.

From CWDP-305:

“Training should be delivered to IT support staff responsible for WLAN operations, and optionally to end-users for user-side clarity. This ensures ongoing support, proper use, and reduced downtime.”

Comprehensive and Detailed Explanation:

The 2.4 GHz band has only three non-overlapping channels: 1, 6, and 11.Using other channels can lead to overlapping and interference.To prevent this, the automatic channel assignment settings should be configured to use only channels 1, 6, and 11, ensuring minimal overlap and optimal performance.

The wavelength (λ) of a radio wave is calculated using the formula:

λ = c / f

Where:

c = speed of light (approximately 3 x 10^8 meters/second)

f = frequency in HzScribd

For 802.11ac operating at 5.5 GHz:Quizlet

λ = 3 x 10^8 / 5.5 x 10^9 ≈ 0.0545 meters ≈ 5.45 cm

This approximates to 5.5 cm (2.16 inches).

An active site survey involves connecting to the WLAN and measuring performance metrics such as throughput and signal strength. During this process, as the surveyor moves through the environment, the client device may transition between different access points. This movement inherently tests the network's roaming capabilities, assessing how seamlessly a client can switch from one AP to another without service interruption.
