Question 3

As an implementation engineer, you have just received initial design specs from a network designer for your dual-band 802.11n deployment. The network design documents prescribe the following data rate configuration for the 2.4 GHz radio:
Basic Rates 5.5, 6, 11, 12 Mbps
Supported Rates 9, 18, 24, 36, 48, and 54 Mbps as well as MCS 0-15
What will result from this design strategy?

A. This configuration violates the IEEE specification that defines 6, 12, and 24 Mbps as mandatory data rates for 802.11g/n.

B. By disabling support for 1 and 2 Mbps while allowing 5.5 and 11 Mbps, the network will force 802.11b clients to use these higher data rates.

C. Protection mechanisms will always be in use on this network to support 5.5 and 11 Mbps as basic rates.

D. HR/DSSS (802.11b) stations will not be able to associate to the service set.

Correct Answer: B

Question 4

While using a USB adapter attached to a USB hub and your laptop for protocol analysts you notice that the SNR is lower than expected. The USB adapter is an 802 11 ac 3x3 3 adapter and is connected to a USB 3 hub. What is likely causing the SNR variation?

A. USB 20 interference

B. EMI from the battery in the device

C. USB 3 0 interference

D. RF incidental energy generated by the cooling fans in the laptop

Correct Answer: C

Question 5

What deliverables should be provided to the customer after successfully implementing a WLAN infrastructure?

A. Nothing is required. The implemented WLAN was the deliverable.

B. Digital or physical assets, guides, floorplans with design information, and configuration documents

C. Project Charter, requirements specification, and software licenses

D. Facility blueprints, NDAs, and hold harmless documents

Correct Answer: B

Question 6

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?
Response:

A. 17 dBm

B. 6.25 mW

C. 125 mW

D. 11 dBm

Correct Answer: A

Question 7

You have initiated a site survey to be performed and the team has been onsite and is halfway through gathering the necessary data.
The project sponsor just asked you to make sure the WLAN supports radio frequency identification (RFID) location tracking. How would you possibly characterize this situation?
Response:

A. The 802.11g standard incorporates location tracking.

B. Any WLAN will support location tracking.

C. The power requirements on the UPS need to be evaluated.

D. Scope creep has occurred.

E. The 802.3af RTLS standard should be incorporated into the AP configuration.

Correct Answer: D

Question 8

You conducted a site survey using two USB Wi-Fi adapters with a special driver designed for the site survey software. After deployment, the client devices show lower RSSI values compared to the results from your survey. What is the most likely reason for this discrepancy?

A. All USB Wi-Fi adapters have a greater sensitivity than internal Wi-Fi adapters

B. USB Wi-Fi adapters designed for site surveys may have better sensitivity than regular Wi-Fi cards installed in client devices

C. Regular Wi-Fi cards installed in client devices do not support the same protocols as survey adapters

D. The transmit power on the APs is higher than needed

Correct Answer: A

A. Perform an active survey using a laptop's built-in adapter

B. Perform a passive survey using a USB wireless adapter

C. Perform a passive survey using a laptop's built-in wireless adapter

D. Perform a passive survey using a special monitor mode adapter

Correct Answer: A

Question 12

Location technology (RTLS) can use which of the following methods?(Choose all that apply.) Response:

A. Sound

B. UHV

C. Passive RFID

D. 802.11-capable laptops

E. UWB

F. Infrared

G. Active RFID

Correct Answer: A,D,F,G

Question 13

While implementing 802.11ax APs in the 6 GHz band, a consultant recommends using WPA2-Personal for VoIP support. Why is this approach technically inappropriate?

A. Because 6 GHz WLANs cannot use WPA2-Personal

B. Because WPA2-Personal causes slower roams than WPA2-Enterprise

C. Because VoIP requires Opportunistic Wireless Encryption (OWE)

D. Because 802.11ax does not support WPA2-Personal in any band

Correct Answer: A

Question 14

When a WLAN controller sends an 802.11 frame to a lightweight AP for transmission on the wireless medium, how does it mark the frame for
802.11 QoS priority?

A. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 routers can do this.

B. The WLAN controller will place the user priority (UP) value in the QoS Control field of the 802.11 frame header before passing it to the lightweight AP.

C. The WLAN controller does not mark the 802.11 frames with priority values only the Layer 3 switches can do this.

D. The WLAN controller does not mark 802.11 frames with priority values only the APs can do this.

Correct Answer: B

Question 15
