Question # 65

When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to

distributed?

A.

APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.

B.

The router between the APs and the controller must be made aware of the APs as forwarding client STAs.

C.

All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.

D.

Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.

Question # 66

A WLAN that you designed has been deployed in one area, users ate complaining that the network performs poorly. When you analyze the area you see that a new interferer has been introduced that was not there during the pre-design survey You've been informed that the interferer cannot be removed as it is an essential loT device. What action do you recommend?

A.

Reconfigure the channel plan to work around the interferer

B.

increase the output power of the APs covering that area by at least 25 percent to overpower the interferer

C.

Place a metal enclosure around the interferer

D.

Use 40 MHz channels so that the devices can use either 20 MHz block depending on where the interferer operates

Question # 67

Given: A WLAN controller is connected to ABC Company's core layer 3 Ethernet switch with an IEEE 802.1Q trunk connection. The WLAN

controller's native

VLAN is VLAN 6 and its IP address is 10.0.14.2 /24. Lightweight APs supporting centralized forwarding are connected to the network on VLANs 7,

8, and 9, and they each build a Layer 3 tunnel back to the WLAN controller's IP address.

The dynamically assigned IP addresses received by each AP from a DHCP server will be ________________.

A.

Associated with the VLAN on which they are connected.

B.

Associated with the native VLAN of the WLAN controller.

C.

Associated with VLAN 1, the default VLAN for new APs

D.

Associated with a non-routable VLAN until the MAC address of the AP is removed from the controller's MAC filter

Question # 68

After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you've

designed the

WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn't follow your guidelines when configuring the WLAN

infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?

A.

Add more APs to the infrastructure

B.

Increase the transmit power on all APs

C.

Turn-off 2.4 GHz radios on some APs

D.

Use all channels available in the 2.4 GHz band

Question # 69

A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?

Response:

A.

Use a plastic cover that could blend in with the environment

B.

Lock the AP inside of a metal box

C.

Place the APs in between walls and I-beams

D.

Use an 802.11b AP, so it looks old enough to be in a museum

Question # 70

Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?

A.

Free space path loss causes greater signal dispersion for higher rate transmissions.

B.

Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.

C.

To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.

D.

Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.

Question # 71

When live video streaming solutions that transmit simultaneously to more than one recipient are used, what special capability should be

considered and configured in all affected WLAN implementations?

A.

IPSec

B.

IPv6

C.

Multicasting

D.

Secure TCP

Full Access
Question # 72

What is the purpose of a Physical Installation Guide document?

A.

To inform the Install technicians of WLAN frame exchanges and communication methods

B.

To provide clear instructions on the locations and mounting methods, and possible configuration steps for APs

C.

To provide sources for purchasing the equipment needed to implement the WLAN

D.

To prove that the WLAN meets the organization's requirements
