What statement about the beamwidth of an RF antenna is true?

1. A. Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.
2. B. Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.
3. C. When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
4. D. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

Correct Answer: A

The center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz). What is the center frequency of channel 4?

1. A. 2.413
2. B. 2.427

Correct Answer: B

You administer a small WLAN with nine access points. As a small business, you do not run 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 times and it is constrained to one area of the building. When using a WLAN scanner, you see that the AP covering that area is online and has a strong signal. No other changes have been made to the environment and all access points are the same model. What is the likely problem?

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

What fact is true regarding controllers and Aps in a split-MAC architecture?

1. A. Using centralized data forwarding, frames leaving the Aps are never tagged Ethernet frames with VLAN identifiers
2. B. An IP tunnel is established between the AP and controller for AP management and control functions
3. C. With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator
4. D. Management and data frames must be processed locally by the AP, while control frames are sent to the controller

Correct Answer: B
