Using a SCA means that all APs will be using the same channel in a given layer. How is the AP with which the client associates determined?

Response:

A.

All APs share a virtual Multicast Address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

B.

All APs share a virtual BSSID. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

C.

All APs share a virtual IP address. A controller will tell the closest AP to the client to communicate with it, since it has a greater RSSI from the client.

D.

The client selects the AP based on a known set of MAC to BSSID mappings stored in the clients authorized SSID listing.

During a customer walkthrough you notice an area of the CAD drawing where it is not accurate. What next step should you take?

Response:

A.

Redraw the portions of the map that have changed.

B.

Do not survey that area.

C.

Request a new version.

D.

Request the survey team to do their best to walk where necessary and use the references on the map.

Your customer's 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room. When doing a walkthrough using one of

these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using your own 802.11 ac laptop,

you're able to see the SSID. What is the most likely cause of this problem?

A.

The AP is configured to use channel 36

B.

The customer laptop does not support Transmit Beamforming

C.

The AP is on channel 144

D.

Their laptops are SISO clients

If radar has reportedly been detected on your WLAN deployment, what bands would you consider avoiding?

Response:

A.

B.

5 GHz UNII-2 and 3

C.

5 GHz UNII-2, 2e, and 3

D.

5 GHz UNII-1 and 2

E.

5 GHz UNII-1, 2, and 3

What VoWiFi implementations frequently require multicast packet delivery support by the WLAN infrastructure?

A.

All VoWiFi implementations

B.

Push-to-Talk VoWiFi phones

C.

All VoWiFi soft phones

D.

All VoWiFi hard phones

You have performed a validation site survey after deploying a WLAN infrastructure that is an All-Wireless-Office. One specific application of your

customer is experiencing delay when using the application after moving from wired connectivity. After your validation, you realized that all APs are

using 80 MHz channel- widths instead of 20 MHz on the 5 GHz band, as it was designed. What can be done to resolve the delay on this

application?

A.

APs should be using 160 MHz channel-widths to get more throughput

B.

Reconfigure to use 20 MHz channel-widths, so reuse of the frequency is more effective

C.

Power-off half of the APs to reduce CCI and keep 80 MHz channel-widths

D.

Add more APs using 80 MHz channel-widths

Who should be in the final meeting from the customer-side after successfully implementing a WLAN infrastructure?

A.

CEO or CFO

B.

End-users

C.

The customer's customers

D.

Remote workers

Modulation can be defined as:

Response:

A.
