• Question 183:

  What are some advantages of designing guest access with all guest users tunneled directly into the DMZ? Response:

  A. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN

  B. Enhances performance of web proxy servers in the DMZ for guest Internet traffic

  C. Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests

  D. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller

  Correct Answer: AD

  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 providesa 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.

• Question 184:

  You are configuring an 802.11ac AP using manual channel planning. The design specification calls for the current AP to be placed on channel 56 in 5 GHz and to disable the 2.4 GHz radio.

  For what could the 2.4 GHz radio be used if not standard AP operations?

  Response:

  A. PCI DSS encoding

  B. Security monitoring

  C. Bluetooth access

  D. Controller-based channel assignment

  Correct Answer: C

• Question 185:

  Modulation can be defined as: Response:

  A. The process of incorporating a chipping code to build resilience

  B. The process of encoding data symbols using a carrier frequency

  C. The process of modifying a carrier signal to represent data

  D. The process of representing data using RF coding

  Correct Answer: C

• Question 186:

  A wireless engineer from your company performed a site survey in an office building where a wireless network extension was needed. He reports that while performing a Layer 1 sweep near a meeting room full of people, he detected RF activity with a very low duty cycle. He is unsure how to interpret what he recorded to determine its impact on a future Wi-Fi network.

  What is true about this RF environment and its potential impact on the WLAN?

  A. The signal affects the entire spectrum and will render the wireless network unusable. It must be located and removed.

  B. The signal has a low duty cycle and should not be of major impact on the wireless network.

  C. The signal is alternating between peaks (high interference level) and valleys (low interference level). The network channel design must be built to avoid the affected peak frequencies.

  D. The signal is typical of a high radio card background noise. It shows that the card used for the Layer 1 sweep should be replaced and the Layer 1 sweep re-

  Correct Answer: B

• Question 187:

  You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.

  What setting would be most effective at achieving this design task?

  A. Set the RTS threshold to 2346 bytes

  B. Set the inactive wireless client timeout (client age-out) to 5 minutes

  C. Set the maximum client limit per radio to 64

  D. Set the DHCP lease for this pool to 20 minutes

  Correct Answer: D

• Question 188:

  When deploying a new WLAN infrastructure using PoE to power the APs, you realize that a known good AP is not powering up. You use the same cable to connect your laptop and connect without any trouble. What is the most likely reason the AP did not power up?

  A. Missing AP licenses in the controller

  B. Spanning-tree convergence

  C. Layer 3 routing

  D. Lack of PoE budget on the switch

  Correct Answer: D

• Question 189:

  Your new customer is concerned about maintaining privacy for their proprietary information when you conduct information gathering for their WLAN design. Which document can you use to directly address their concern?

  A. NDA

  B. SoW
