Question 1

An RF signal sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?

Reflection
Refraction
Scattering
Warping

Correct answer: B

Question 2

A WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB loss. If the cable is connected to an antenna with 9dBi gain, what is the EIRP at the antenna element?

23 dBm
26 dBm
13 dBm
10 dBm

Correct answer: A

Explanation:

Question 4

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

Dish and grid
Dipole and yagi
Grid and sector
Patch and panel

Correct answer: D

Question 5

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

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

Correct answer: A

Question 6

Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to-point WLAN bridge link?

MU-MIMO capabilities of the bridges
Receive antenna gain
Transmit power
Operating frequency

Correct answer: A

Question 7

You are implementing a VHT-capable AP. Which one of the following channels is available in the 802.11-2016 standard that was not available before the ratification of 802.11 ac?

153
161
144
56

Correct answer: C

Explanation:

Question 8

What ID is typically mapped to an AP’s MAC address if a single BSS is implemented?

VLAN ID
BSSID
Device ID
SSID

Correct answer: B

Question 9

When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?

For each probe request frame, only one AP may reply with a probe response.
Each AP responds in turn after preparing a probe response and winning contention.
Each AP checks with the DHCP server to see if it can respond and then acts accordingly.
After waiting a SIFS, all APs reply at the same time with a probe response.

Correct answer: B

Question 10

You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?

400 ns
10 ms
800 ns
104 ms

Correct answer: A
