Free Practice Questions for CWNP CWDP-305 Exam

Comprehensive and Detailed Explanation:

An LLD (Low-Level Design) document contains technical specifications and granular configuration details about the WLAN infrastructure. This includes VLAN mappings, IP address schemes, and what network devices (e.g., switches or routers) are responsible for routing between VLANs.

“LLD” is the correct type of document to specify VLAN configuration in detail.

“Routing” is the correct function when VLANs must communicate with each other across subnets, and the document should indicate which devices perform inter-VLAN routing.

“The Low-Level Design includes VLAN assignments, routing roles, IP schemas, and all technical details that installers and engineers need to configure the system.”

EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) is the most secure EAP type that utilizes certificates for mutual authentication between the client and the server.In this method, both the client and the server present certificates to authenticate each other, eliminating the need for passwords and providing strong security against various attacks.

The CWDP-305 Official Study and Reference Guide emphasizes the importance of using EAP-TLS in environments where strong security is required:

"EAP-TLS is considered one of the most secure EAP types because it uses certificates for both client and server authentication. It provides mutual authentication and is widely supported."

Therefore, for organizations seeking to enhance their WLAN security by moving away from PSK and implementing certificate-based authentication, EAP-TLS is the recommended choice.

In a bandpass filter, the ripple refers to the variation in insertion loss within the passband.If the maximum in-band loss is 1.5 dB and the ripple is 0.4 dB, the minimum in-band loss can be calculated by subtracting the ripple from the maximum loss:blog.knowlescapacitors.com

1.5 dB (maximum loss) - 0.4 dB (ripple) = 1.1 dB (minimum loss)

Therefore, the minimum in-band loss is 1.1 dB.

Before engaging with a customer, it's crucial to conduct thorough research to understand their business operations, objectives, and challenges. This preparation allows you to tailor your approach and solutions to their specific needs.

Key aspects to research include:

Business Model:Understand the core services or products the company offers.

Customer Base:Identify the primary customers or clients they serve.

Recent Developments:Review recent press releases, news articles, or announcements to stay informed about any significant changes or initiatives.

This proactive approach demonstrates professionalism and a genuine interest in the customer's success, fostering trust and facilitating more productive discussions.

Comprehensive and Detailed Explanation:

Using wider channel widths like 80 MHz can increase throughput but also reduces the number of available non-overlapping channels, leading to increased co-channel interference (CCI), especially in dense environments.Reconfiguring APs to use 20 MHz channel-widths enhances frequency reuse and minimizes CCI, thereby improving application performance in an All-Wireless-Office setup.

In high-density venues such as stadiums or convention centers, the presence of large crowds significantly impacts Wi-Fi signal propagation. Human bodies consist mostly of water, which absorbs and attenuates radio frequency (RF) signals, especially in the 2.4 GHz and 5 GHz bands commonly used by Wi-Fi. This absorption leads to reduced signal strength and potential connectivity issues during events when the venue is filled with people.

Designing a WLAN for such environments requires careful consideration of crowd density and its impact on RF signals. Strategies may include increasing the number of APs, using directional antennas to focus coverage, and conducting site surveys during events to assess real-world performance.

Centralized data forwarding means all wireless traffic is tunneled back to a central controller, which handles tasks such as filtering, firewalling, and policy enforcement.

From CWDP-305:

“Centralized data forwarding enables consistent policy enforcement and traffic filtering by handling all traffic at the controller rather than at individual APs.”

This approach provides better control and visibility, especially in environments with strict security and traffic management requirements.

The most accurate method to determine wall attenuation is to perform empirical measurements. First, measure the Received Signal Strength Indicator (RSSI) in free space at a known distance, such as 1 meter (3 feet). Then, place the access point 0.32 meters (1 foot) away from one side of the wall and the measuring device 0.67 meters (2 feet) away on the opposite side. By comparing the RSSI readings from the free space and through the wall, you can calculate the wall's attenuation. This method accounts for real-world variables and provides more accurate data than relying solely on predictive models or manufacturer specifications.

The Bill of Materials (BoM) is a comprehensive list that details all the components, devices, and parts required for the deployment of a WLAN infrastructure.It serves as a critical document for procurement and ensures that all necessary items are accounted for before the deployment begins.

The CWDP-305 Official Study and Reference Guide emphasizes the importance of the BoM in the design and deployment process:

In an independent autonomous architecture, each AP operates independently without coordination with other APs.This lack of centralized control or coordination mechanisms limits the ability to share control information, such as client roaming data or RF management decisions, across APs.As a result, features like seamless roaming and dynamic RF adjustments are challenging to implement effectively in such architectures.
