NEW QUESTION # 140
ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-
2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.
When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA's IP data packet gets mapped to what and by which device?
- A. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point.
- B. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.
- C. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.
- D. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point.
Answer: B
Explanation:
In a centralized data forwarding architecture, Access Points (APs) tunnel all client traffic to the WLAN controller.The controller then processes this traffic and forwards it to the appropriate destination.During this process, the controller maps the Differentiated Services Code Point (DSCP) values from the client's IP packets to the appropriate IEEE 802.1Q priority tag values.This mapping ensures that Quality of Service (QoS) is maintained across the wired network, allowing switches and routers to prioritize traffic based on these tags.Cisco Reference: CWDP-305 Official Study and Reference Guide, Chapter on Infrastructure Design
NEW QUESTION # 141

- A. Use a plastic cover that could blend in with the environment
- B. Place the APs in between walls and I-beams
- C. Lock the AP inside of a metal box
- D. Use an 802.11b AP, so it looks old enough to be in a museum
Answer: A
NEW QUESTION # 142
In high-density environments like stadiums or convention centers, what additional factor must be considered that can attenuate Wi-Fi signals during events?
- A. People
- B. Thick walls
- C. Fire doors
- D. I-Beams
Answer: A
Explanation:
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.

NEW QUESTION # 143
Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces, and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface.
Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?
- A. Cat-5e
- B. Cat-6
- C. Cat-5
- D. Cat-6a
Answer: D
Explanation:
For cable runs exceeding 55 meters (180.5 feet) and to support 802.3bz MultiGig speeds (2.5GBASE-T and
5GBASE-T), it's recommended to use Cat-6a cabling. Cat-6a cables are designed to handle higher frequencies and provide better performance over longer distances compared to Cat-5e or Cat-6, making them suitable for MultiGig applications.
The CWDP-305 Official Study and Reference Guide highlights the importance of selecting appropriate cabling to support higher data rates:
"When deploying MultiGig Ethernet, especially for cable lengths exceeding 55 meters, Cat-6a cabling is recommended to ensure reliable performance and compliance with standards." Reference: CWDP-305 Official Study and Reference Guide, Chapter on Infrastructure Design

Answer: A
NEW QUESTION # 145
Why should band steering algorithms allow stations to connect to the 2.4 GHz band after some number of ignored Probe Requests?
- A. Because the AP will experience a buffer overflow if they do not eventually respond with a Probe Response.
- B. Because the FCC requires it.
- C. Because some clients are persistent clients that will not move on to the 5 GHz band.
- D. Because the 802.11 standard requires it.
Answer: C
Explanation:
Band steering is a technique used to encourage dual-band clients to connect to the less congested 5 GHz band.
However, some clients may not respond to steering attempts and persist in attempting to connect on the 2.4 GHz band.To ensure connectivity for these persistent clients, APs are designed to eventually respond to their Probe Requests on the 2.4 GHz band after a certain number of ignored attempts.
The CWDP-305 Official Study and Reference Guide states:
"Band steering mechanisms must account for clients that do not support or respond to steering attempts, allowing them to connect on the 2.4 GHz band after a defined number of ignored Probe Requests." Reference: CWDP-305 Official Study and Reference Guide, Chapter on ProtocolandSpectrum Analysis
NEW QUESTION # 146
What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag?
- A. When it is off
- B. When it is not authenticated
- C. When its radio is disabled
- D. When its radio is disabled
- E. Lack of 802.11k support
- F. Lack of 802.11k support
- G. When it is off(Note: Options B and C are duplicates. This appears to be a typo. We'll treat C as intended to be unique.)Corrected Options:
- H. When its radio is disabled
Answer: G
Explanation:
The ability to locate a client device using WLAN infrastructure relies on the client actively transmitting frames that can be detected by multiple access points. These frames are typically management or data frames used during association, authentication, or normal operation.
If the client device is turned off, it is not transmitting any 802.11 frames. Therefore, the infrastructure cannot detect or triangulate its location using standard methods such as RSSI (Received Signal Strength Indicator) or time difference of arrival.
According to the CWDP-305 Official Study and Reference Guide (Chapter: Designing for Specific Applications), location-based services (LBS) are dependent on the active participation of the client device.
Without beacon frames, probe requests, or any other 802.11 activity, no positioning data can be gathered.
"Client devices must be actively transmitting for their location to be calculated through triangulation or trilateration. If a device is powered off, it cannot be tracked by the WLAN infrastructure."
