CWNP CWDP-305 Dumps Questions Answers

Comprehensive and Detailed Explanation:

Hiding the Service Set Identifier (SSID) can serve specific purposes, such as:

Preventing guests from attempting to join the secured corporate network:By not broadcasting the corporate SSID, casual users are less likely to attempt connections, reducing unauthorized access attempts.

Minimizing help desk calls from users and guests attempting to join the wrong network:When only the guest network SSID is visible, it simplifies the connection process for visitors, leading to fewer support requests.

However, it's important to note that SSID hiding is not a robust security measure. Determined attackers can still detect hidden networks using various tools, as the SSID can be revealed in certain management frames like probe requests and association requests.

Real-Time Location Systems (RTLS) require precise triangulation, which can only occur if a device is detected by at least three APs with strong RSSI values from various angles. The best accuracy is achieved by placing APs around the perimeter and within the area so devices are surrounded.

From CWDP-305:

“For accurate Wi-Fi location tracking, ensure that client devices can be detected by a minimum of three, preferably four, APs with good signal strength. APs should be placed around the perimeter and within the location zone for proper triangulation.”

USB 3.0 operates with signaling rates up to 5 Gbps, which can emit electromagnetic interference in the 2.4 GHz frequency band. This interference can elevate the noise floor in the 2.4 GHz spectrum, leading to inaccurate readings during site surveys. The CWDP-305 study guide highlights this issue, emphasizing the importance of being aware of potential interference sources during surveys.

To mitigate this, it's recommended to use USB 2.0 devices or ensure that USB 3.0 devices are adequately shielded and positioned away from Wi-Fi antennas during surveys.
