Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere each other when they transmit frames. Assuming no other Aps are in the vicinity, is CCI still a possibility in this network and why?

1. A. Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as
2. B. No, because the Aps are far enough apart that no CCI will occur
3. C. No, because CCI only occurs in the 5 GHz frequency band
4. D. Yes, because channel 11 loops around and causes CCI with channel 1

Correct Answer: A

Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?

1. A. The use of cables longer than one meter in the RF system
2. B. High output power at the transmitter and use of a low-gain antenna
3. C. A Voltage Standing Wave Ratio (VSWR) of 1:1
4. D. An impedance mismatch between components in the RF system

Correct Answer: D

You administer a small WLAN with nine access point. As a small business, you do not rum a RADIUS server and use WPA2-Personal for security. Recently, you changed the passphrase for WPA2-personal in all Aps and clients. Several users are now reporting the inability to connect to the network at time and it is constrained to one area of the building. When using scanner, you see that the AP covering that area is online

1. A. The AP that covers the problem area requires a firmware update
2. B. The clients are improperly configured
3. C. The AP that covers the problem area has failed
4. D. The AP that covers the problem area is improperly configured

Correct Answer: A

You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of this connection?

1. A. Less than 150 Mbps because of 802.11 overhead and contention
2. B. 54 Mbps because that is the actual maximum throughput of an 802.11 connection
3. C. More than 150 Mbps because of compression
4. D. 150 Mbps because the data rate is equal to the throughput

Correct Answer: A

What primary metric of scanning can stations use to select the best AP for connectivity to the desired BSS?

1. A. Signal strength of AP beacons received.
2. B. PING latency when testing against an Internet server.
3. C. FCS errors in frames transmitted to and from the AP.
4. D. Throughput speed in Mbps.

Correct Answer: A
