NEW QUESTION # 55
In a PC-based spectrum analyzer, what data chart identifies the overall RF utilization of a specific frequency in the environment being surveyed?
- A. FFT Max Hold
- B. Duty Cycle
- C. Swept Spectrogram
- D. FFT Average
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
The Duty Cycle chart in a spectrum analyzer represents the percentage of time a specific frequency is occupied by RF energy above a certain threshold. This measurement is crucial for identifying how much of the channel's capacity is being utilized, which aids in determining potential interference and channel availability for WLAN deployment. A high duty cycle indicates that the frequency is heavily utilized, possibly leading to contention and reduced performance.

NEW QUESTION # 56
What service must be implemented on your customers' network to authenticate users against an LDAP database prior to access to the WLAN infrastructure being granted?
- A. SFTP
- B. TLS
- C. RADIUS
- D. NTP
Answer: C
Explanation:
Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.When integrating with an LDAP directory, RADIUS servers can authenticate users against the LDAP database before granting access to the WLAN infrastructure.
The CWDP-305 Official Study and Reference Guide notes:
"What service must be implemented on your customer's network to authenticate users against an LDAP database before granting access to the WLAN infrastructure? B. RADIUS"Pass4Success Reference: CWDP-305 Official Study and Reference Guide, Chapter on Designing for Specific Applications What is the best method of gathering attenuation measurements from any building materials or objects?
A: After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the difference.B. Use the pre-built attenuation values in the predictive design tool.C. After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side. Take measurements and compare the difference.D.
Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider's websites.
The most accurate method to determine the attenuation of specific building materials is to perform empirical measurements.This involves measuring the Received Signal Strength Indicator (RSSI) in free space at a known distance and then measuring the RSSI with the material between the transmitter and receiver.The difference in RSSI values indicates the attenuation caused by the material.
The CWDP-305 Official Study and Reference Guide emphasizes the importance of empirical measurements:
"To accurately measure attenuation, perform a free-space measurement at a known distance, then place the material between the transmitter and receiver and measure again. The difference in signal strength represents the material's attenuation." Reference: CWDP-305 Official Study and Reference Guide, Chapter on Advanced Site Surveys
NEW QUESTION # 57
A table of VLANs in a _________ document should include what device performs ________ services.
- A. HLD, QoS
- B. LLD, bridging
- C. HLD, routing
- D. LLD, routing
Answer: D
Explanation:
In the context of wireless network design, documentation is typically divided into two primary categories:
High-Level Design (HLD) and Low-Level Design (LLD).
High-Level Design (HLD):Provides an overview of the network architecture, including major components and their relationships. It focuses on the overall design without delving into specific configurations.
Low-Level Design (LLD):Offers detailed information about the network, including specific configurations, IP addressing schemes, VLAN assignments, and device roles.
When documenting VLANs, the LLD should include a table that specifies which devices perform routing services for each VLAN. This level of detail ensures that during implementation, network engineers have clear guidance on how to configure each device to handle inter-VLAN routing appropriately.

NEW QUESTION # 61
Which DHCP option, when required, must be configured to help access points (APs) locate their wireless LAN controller (WLC) during deployment?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
DHCP Option 43 is a vendor-specific option used by lightweight access points to locate their Wireless LAN Controller (WLC) when no static discovery method (like DNS or manual config) is provided. During the DHCP request process, the AP receives Option 43 information that includes the WLC's IP address. This is a standard method in controller-based WLAN deployments and is explicitly called out in the CWDP-305 Study Guide.

NEW QUESTION # 63
When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?
- A. AP vendor
- B. Band steeringCWNPUdemy
- C. Roaming
- D. Frequency Selection
Answer: C
Explanation:
Comprehensive and Detailed Explanation:
In voice over WLAN (VoWLAN) deployments, seamless roaming is critical to maintain call quality. As users move throughout the office, their devices must transition between access points without dropping the call or experiencing latency. Therefore, ensuring efficient and fast roaming capabilities is paramount in the design of a WLAN intended to support voice applications.
NEW QUESTION # 64
Main Topic:Advanced Site Surveys
Question:
Left to its simplest form, what method does a location algorithm use to determine location within a WLAN coverage area?
- A. Inverse cube law
- B. 802.11 clause 16
- C. FSPL
- D. RF fingerprinting
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
RF fingerprinting is a method used in WLANs to determine the location of a device by comparing the current signal characteristics (like signal strength and quality) to a pre-recorded database of signal profiles (fingerprints) taken at various locations. This technique allows for accurate indoor positioning without relying solely on signal strength calculations.
Option A:Inverse cube law is not typically used in WLAN location algorithms.
Option B:Free Space Path Loss (FSPL) calculations are more theoretical and less effective in complex indoor environments.
Option D:Clause 16 of the 802.11 standard pertains to mesh networking, not location algorithms.

NEW QUESTION # 66
What are the best practices for better location accuracy when deploying Wi-Fi RTLS?
- A. Place APs in the center of the required area and make sure that every client device is able to hear at least three APs
- B. Place APs on the perimeter and throughout the required area and make sure that every client device is able to "hear" at least three APs
- C. Place APs in the center of the required area and make sure that every client device is able to hear at least two APs
- D. Place APs on the perimeter of the required area and make sure that every client device is able to "hear" at least one AP
Answer: B
Explanation:
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."

- D. The design will use MU-MIMO, which is not available in either 802.11n or 802.11ac.
Answer: A
