CWNP Updated CWDP-305 Exam Questions and Answers by sage

EAP-TTLS (Extensible Authentication Protocol - Tunneled Transport Layer Security) is designed to provide secure authentication using a server-side certificate while allowing for optional client-side certificates. This flexibility makes it suitable for environments where client credentials (such as usernames and passwords) are used, and the server must present a certificate, but client certificates are not mandatory.

The CWDP-305 Official Study and Reference Guide explains:

"EAP-TTLS allows the use of server-side certificates to establish a secure tunnel, within which client authentication can occur using various methods, including username/password. Client certificates are optional, providing flexibility in deployment."

Comprehensive and Detailed Explanation:

The IEEE 802.11 standard does not mandate a specific calibration accuracy for Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) reporting across client devices. RSSI values are relative and can vary between different hardware vendors, as each manufacturer may implement their own scale and measurement methods. This lack of standardization means that RSSI readings are not directly comparable across different devices. Therefore, there is no specific value to which clients are required to be calibrated for RSSI and SNR reporting.

Comprehensive and Detailed Explanation:

After implementing a WLAN infrastructure, it's essential to provide the customer with comprehensive documentation.This includes digital or physical assets, user guides, floorplans indicating AP placements, and configuration documents detailing network settings.These deliverables ensure the customer can manage, maintain, and troubleshoot the WLAN effectively.Reddit

In outdoor environments, channel contention, co-channel interference (CCI), and adjacent channel interference (ACI) can negatively affect bridge performance. The most effective method for identifying usable channels is through a site survey, which includes spectrum analysis at both endpoints.

From CWDP-305:

“Performing an outdoor site survey is critical for point-to-point deployments. This reveals existing RF usage in the area, allowing the selection of channels with minimal interference for optimal link stability.”
