CWNP Updated CWDP-305 Exam Questions and Answers by maddox

In wireless site surveys, especially when using predictive modeling tools,calibrationis a critical step to ensure that the simulated RF coverage accurately reflects the real-world environment.

Calibration involves measuring actual signal strengths at various locations within the environment and adjusting thesimul-ationparameters accordingly. This process accounts for real-world factors such as wall materials, furniture, and other obstructions that can affect signal propagation.

Failing to calibrate thesimul-ationcan lead to discrepancies between predicted and actual coverage, potentially resulting in poor network performance and user experience.

The Physical Installation Guide is developed during the design phase and delivered to the installation team. It contains detailed AP locations (including mounting heights and orientations), cabling instructions, hardware installation standards, and any specific AP configuration notes needed during physical deployment.

From CWDP-305:

“A Physical Installation Guide provides specific instructions to installers, such as mounting height, orientation, and any environmental considerations. This ensures that APs are installed correctly and according to the design.”

In the 5 GHz band, certain channels like 144 are not universally supported across all devices, especially older 802.11n clients. If the AP is operating on channel 144, and the client's regulatory domain or hardware does not support this channel, the SSID will not be visible to the client.

The CWDP-305 Official Study and Reference Guide notes:

"Client devices may not support all channels in the 5 GHz band, depending on their regulatory domain and hardware capabilities. Channel 144, for example, is not supported by all 802.11n clients."

Comprehensive and Detailed Explanation:

For enterprises requiring high network uptime, it's crucial to design for redundancy and failover in both the wireless and wired components of the network. This includes:

Wireless and Wired Network Failover:Ensuring that both wireless access points and wired infrastructure have redundancy to prevent single points of failure.

Physical Aspects (Power and Cabling):Implementing redundant power supplies, uninterruptible power supplies (UPS), and proper cabling practices to maintain network availability during power outages or hardware failures.
