NEW QUESTION # 101
After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel widths and all 25 available channels, a manager tests the Guest SSID on his 802.11n tablet. During testing, he experiences several areas with poor RSSI (below -80 dBm) or no signal at all. Upon checking, all APs are operational, and coverage was validated post-deployment. What is the likely cause of this issue?
- A. His tablet doesn't support the 5 GHz band
- B. His tablet only supports a 40 MHz channel-width
- C. His tablet doesn't support MU-MIMO
- D. His tablet does not support one or more of the 5 GHz channels
Answer: D
Explanation:
This issue arises due to partial support for 5 GHz channels by some client devices. Although the infrastructure may use all 25 available 5 GHz channels in the U.S. (spanning UNII-1 through UNII-3 and DFS channels), many older 802.11n tablets and clients only support a subset of these channels-commonly the lower UNII-1 band (channels 36-48). As a result, even though the APs are operational and signal coverage is valid overall, the client may not see or associate with APs operating on unsupported 5 GHz channels such as channels 52-
64 or DFS channels (100-144).
This leads to inconsistent connectivity or lack of signal in areas where APs are broadcasting on unsupported channels. The CWDP-305 Study Guide advises taking client capability into account during design validation and includes best practices for mapping expected device support versus operational channel plans.

NEW QUESTION # 105
Your customer requires a security solution where client credentials are used, not a Protected Access Credential (PAC), and the authentication server must have a certificate with optional client certificate use.
Which EAP (Extensible Authentication Protocol) method is the best fit for these requirements?
- A. EAP-FAST
- B. EAP-TTLS
- C. LEAP
- D. EAP-TLS
Answer: B
Explanation:
EAP-TTLS (Extensible Authentication Protocol - Tunneled Transport Layer Security) is an authentication protocol that allows the use of client credentials (such as usernames and passwords) while requiring a server- side certificate. Client-side certificates are optional, making it a flexible solution for environments where deploying certificates to all clients is impractical. This method establishes a secure tunnel between the client and server, ensuring that credentials are protected during the authentication process.

What is the chip rate of 1 Mbps 802.11b?
- A. 1 Mchip/s
- B. 11 Mchips/s
- C. 2 Mchips/s
- D. 22 Mchips/s
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
In 802.11b, the 1 Mbps data rate usesDirect Sequence Spread Spectrum (DSSS)with an 11-bit Barker code.
Each bit of data is represented by an 11-chip sequence, resulting in a chip rate of:
1 Mbps × 11 chips/bit = 11 Mchips/s
However, thechip raterefers to the rate at which the chips (the smaller units of data in DSSS) are transmitted.
For 802.11b, the chip rate is11 Mchips/sfor the 1 Mbps data rate.

NEW QUESTION # 114
What are some advantages of designing guest access with all guest users tunneled directly into the DMZ?
Response:
- A. Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests
- B. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN
- C. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller
- D. Enhances performance of web proxy servers in the DMZ for guest Internet traffic
Answer: B,C
Explanation:
Designing guest access with all guest users tunneled directly into the DMZ has two main advantages: it simplifies the network configuration and it enhances the security of the internal network. A DMZ is a demilitarized zone, which is a separate network segment that isolates the public-facing services from the private network. A DMZ provides a buffer zone between the Internet and the internal network, where potential attacks can be detected and prevented.
By tunneling all guest users directly into the DMZ, the network configuration is simplified because there is no need to segment and filter the guest traffic across the internal LAN. The guest traffic is encapsulated and routed to the DMZ controller, which acts as the anchor point for the guest WLAN. The guest traffic is then decrypted and forwarded to the Internet or the DMZ services. This way, the guest traffic does not mix with the internal traffic, and there is no need to apply VLANs, ACLs, or firewall rules to separate them.
Another advantage of tunneling all guest users directly into the DMZ is that it enhances the security of the internal network. By keeping the guest traffic in the DMZ, the internal network is protected from any potential threats or attacks that may originate from the guest users. The guest users have no visibility or access to the internal network resources, and they are subject to the security policies and controls of the DMZ. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller, because the guest traffic is already encapsulated and tunneled. This reduces the complexity and the risk of misconfiguration of the firewall rules.

NEW QUESTION # 115
What statements are true regarding jitter and latency?(Choose all that apply.) Response:
- A. Latency is a measurement of the time delay experienced in the delivery of a frame.
- B. Latency is a measurement of the time required to transmit two subsequent frames.
- C. Jitter is a measurement of the variance of the number of frames received from an application for a specific time interval.
- D. Jitter is a measurement of latency variability from one frame to another.
- E. Jitter is a measurement of average latency based on a sample of >100 frames.
Answer: A,D
Explanation:
Jitter and latency are two important metrics for measuring the quality and performance of wireless networks, especially for real-time applications such as voice and video. Latency is the average time taken for a data packet to reach the destination, while network jitter is the irregularity in latency. When the latency is consistently high, it can mean a slow but stable connection. On the other hand, a high jitter means there may be sporadic disruptions or delays in the transmission, which can affect the quality of service and user experience. Jitter is caused by various factors, such as network congestion, interference, routing changes, hardware issues, or packet prioritization. Jitter can be measured by calculating the difference between the latency of two consecutive packets, or by using the standard deviation of the latency of a sample of packets.
Jitter can be reduced by using Quality of Service (QoS) mechanisms, such as traffic shaping, queuing, or scheduling, which can prioritize the packets based on their importance and sensitivity to delay. Jitter can also be mitigated by using jitter buffers, which can store the incoming packets and smooth out the variations in latency before delivering them to the application.

NEW QUESTION # 117
Main Topic:Wireless Design Process
Question:
When designing for a PTP outdoor link, what important consideration should be made about local vegetation?
(Choose all that apply.)
- A. Water density
- B. Tree height growth
- C. Leaves
- D. Reflection factor
Answer: A,B,C
Explanation:
Comprehensive and Detailed Explanation:
In designing Point-to-Point (PTP) outdoor wireless links, local vegetation plays a significant role in signal propagation and potential attenuation. Key considerations include:
A: Leaves:Foliage, especially leaves, can absorb and scatter RF signals, particularly at higher frequencies.
Seasonal changes can affect signal strength due to varying leaf density.
B: Tree height growth:Over time, trees can grow into the line-of-sight path, causing signal obstruction.
Planning should account for potential future growth to maintain clear paths.
C: Water density:Vegetation with high water content can absorb RF energy, leading to increased signal attenuation. This is especially pertinent in areas with lush, dense foliage.
D: Reflection factor:While reflections can impact signal quality, in the context of vegetation, absorption and scattering are more critical factors than reflection.

NEW QUESTION # 118
What roaming technology uses stored keys at the APs for roam back if a client STA returns after having roamed away?
- A. SCA roaming
- B. PMK caching
- C. OKC
- D. Preauthentication
Answer: B
Explanation:
PMK caching(Pairwise Master Key caching) is a roaming technology where the access point (AP) stores the PMK derived during the initial authentication of a client station (STA).If the client roams away and then returns to the same AP, the stored PMK allows for a quicker re-association without the need for a full authentication process.
This mechanism enhances roaming efficiency by reducing latency during re-association, which is particularly beneficial for applications sensitive to delays, such as VoIP.
