Question 1

You are performing a WLAN analysis process wherein you move through the environment and actively send and receive data to and from the AP and network. The statistics are gathered including throughput rates.
What kind of process is being performed?

A. Active Site Survey

B. Spectrum analysis

C. Protocol capture

D. Passive Site Survey

Correct Answer: A

Question 2

You have selected to plan and install a controller-based WLAN. The network consists of 53 Ethernet switches running all gigabit and higher ports. Twelve network segments exist separated by routers. The WLAN controller will be placed in the network operations center. Three servers run services like DHCP, DNS and NTP.
In addition to the routers, where could ACLs be deployed that impact only the WLAN?

A. DNS server

B. Controller

C. DHCP server

D. Swith ports connected to the wired LAN

Correct Answer: D

Question 3

When testing the signal strength and capacity in a site survey, which client type is generally best to use?

A. a single stream tablet

B. the most capable client type that will be used on the network.

C. a 3x3:3 laptop

D. the least capable client type that will be used on the network.

Correct Answer: C

Question 4

ABC, Inc. has chosen a WLAN solution that implements a controller-based architecture. The APs will discover the controller using DHCP, broadcast messages, DNS resolution or some other proprietary method.
During operation, what protocol is likely to be used for the communications between the APs and the controllers?

A. PPTP

B. L2TP

C. IPSec

D. LWAPP

Correct Answer: D

Question 5

You have discovered three coverage holes during WLAN validation testing. All three exist on the same floor.
Which one of the following is the best solution for coverage hole removal while not reducing the overall capacity of the WLAN?

A. Remove one or more APs

B. Increase the output power of the radio in all APs

C. Decrease the output power of the client devices

D. Add one or more APS

Correct Answer: B

Question 6

When a virtual controller architecture is in use, with most vendor solutions, how is the virtual controller assigned?

A. By the administrator through DNS configuration

B. By election among the physical controllers

C. By election among the APs

D. By the administrator directly

Correct Answer: D

Question 7

When a WLAN controller sends an 802.11 frame to a lightweight AP for transmission on the wireless medium, how does it mark the frame for 802.11 QoS priority?

A. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 routers can do this.

B. The WLAN controller will place the user priority (UP) value in the QoS Control field of the 802.11 frame header before passing it to the lightweight AP.

C. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 switches can do this.

D. The WLAN controller does not mark 802.11 frames with priority values only the APs can do this.

Correct Answer: B

Question 8

During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS. This frame is typical of those that were captured by the analyzer.
What does this frame reveal about the RF network in this area?

A. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control

B. Contention Free is in place in this network, which may starve some non-QoS stations from access

C. Multipath or excessive collisions seem to be an issue in this area

D. The AP seems to be too far to provide enough coverage to this area

Correct Answer: C

Question 9

What document might specify that RF propagation patterns, AP locations and configurations, and potential sources should be documented?

A. Hold harmless

B. NDA

C. Site survey deliverables

D. Project charter

Correct Answer: D
