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 with each other when they transmit frames. Assuming no other APs are in the vicinity, is CCI still a possibility in this network and why?

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 clients connected to the other channel 1 AP.

B.

No, because the APs are far enough apart that no CCI will occur.

C.

No, because CCI only occurs in the 5 GHz frequency band.

D.

Yes, because channel 11 loops around and causes CCI with channel 1.

Which one of the following 802.11 PHYs is more likely to be used in an industrial deployment but not likely to be used in standard office deployments?

A.

SIG

B.

VHT

C.

OFDM

D.

HT

A client STA must choose the best AP for connectivity. As part of the evaluation, it must verify compatible data rates. What can the client STA use to verify that an AP supports the same data rates that it supports?

A.

Beacon frames transmitted by the AP

B.

Data frames sent between the AP and current clients STAs

C.

Authentication frames transmitted by the other client STAs

D.

Probe request frames transmitted by other client STAs

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

A.

Using centralized data forwarding, frames leaving the Aps are never tagged Ethernet frames with VLAN identifiers

B.

An IP tunnel is established between the AP and controller for AP management and control functions

C.

With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator

D.

Management and data frames must be processed locally by the AP, while control frames are sent to the controller

When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain, what antenna characteristic will decrease?

A.

Range

B.

Beam width

C.

Active gain

D.

Receive sensitivity

You are using a tool that allows you to see signal strength for all Aps in the area with a visual representation. It shows you SSIDs available and the security settings for each SSID. It allows you to filter by frequency band to see only 2.4 GHz networks or only 5 GHz networks. No additional features are available.

What kind of application is described?

A.

Protocol analyzer

B.

Site survey utility

C.

Spectrum analyzer

D.

WLAN scanner tool
