CWNP Updated CWDP-305 Exam Questions and Answers by payton

Comprehensive and Detailed Explanation:

Per-user Pre-Shared Keys (PSKs) offer several advantages over a single PSK used across an entire Extended Service Set (ESS):

User-Based Access Control:Assigning unique PSKs to individual users allows for better tracking and control over network access.

Simplified Key Management:If a user's PSK is compromised or they leave the organization, only their key needs to be changed, not the entire network's.

Option C:Per-user PSKs are not a standard defined or certified by the Wi-Fi Alliance; they are an implementation choice.

Option D:Mutual authentication is a feature of WPA/WPA2-Enterprise using 802.1X, not of PSK-based systems.

Comprehensive and Detailed Explanation:

IEEE 802.3at, also known as PoE+, provides up to 25.5 watts of power per port. To support 6 access points requiring PoE+ power:

25.5 W/AP × 6 APs = 153 W

Considering some overhead for power loss and future scalability, a minimum PoE budget of 180 W is recommended to ensure reliable operation.

Coverage must be validated from the perspective of the least capable or lowest-spec client device expected in the environment. This ensures that all necessary devices—not just the most capable ones—can associate and operate reliably.

From CWDP-305:

“Validating coverage should focus on the least capable client device since it will typically have the weakest radio and lowest sensitivity. This ensures all users can connect and meet performance requirements.”

Comprehensive and Detailed Explanation:

An elevation chart provides a vertical radiation pattern of an antenna, which is essential for understanding how the antenna directs energy above and below the horizon. In bridge link deployments, especially over varying terrains or between buildings of different heights, the elevation pattern helps in aligning antennas to ensure optimal signal propagation and reception. Requesting elevation charts from antenna vendors allows for informed decisions on antenna placement and orientation, leading to more reliable and efficient wireless links.
