A. 802.1X security B. Traffic tunneling or anchoring C. 802.11n D. SSID segmentation E. Rate limiting

Correct Answer: B,E

Question 2

After designing a WLAN infrastructure using predictive design software. What's the best way to validate the predictive design in the physical space before deployment, if time and budget allow for it?

A. Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement. B. Use a client device positioned where the APs will be installed and measure the signal from the client device. C. Deploy all of the APs as they're shown in the predictive design and perform an active site survey. D. Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

Question 3

For an antenna 35 dBi of gain is needed. What antenna type should be used to achieve this gain?
Response:

A. Yagi B. Dish C. 4# dipole D. Horn

Correct Answer: B

Question 4

What is the most suitable antenna option to be used when designing a WLAN infrastructure with APs mounted on a ceiling with a height of more than 20 feet and having all of the client stations used from the floor?
Response:

A. Dish B. Patch C. Grid D. Low-gain dipole

Correct Answer: B

Question 5

What type of protection should be provided to outdoor antenna installations?
Response:

A. Brownouts B. A/C spikes C. Static electricity D. Lightning surge suppression

Correct Answer: D

Question 6

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. Their laptops are SISO clients B. The customer laptop does not support Transmit Beamforming C. The AP is on channel 144 D. The AP is configured to use channel 36

Correct Answer: C

Question 7

Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?

A. Free space path loss causes greater signal dispersion for higher rate transmissions. B. Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding. C. To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases. D. Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.

Correct Answer: B

Question 8

For what purpose is SSID hiding generally useful?(Choose all that apply.) Response:

A. Minimizing help desk calls from users and guests attempting to join the wrong network B. Preventing guests from attempting to join the secured corporate network C. Preventing legitimate corporate users from finding the guest network D. Obscuring the network name from potential attackers

Correct Answer: A,B

Question 9

ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.
When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA's IP data packet gets mapped to what and by which device?

A. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point. B. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point. C. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller. D. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.

Correct Answer: C

Question 10

When implementing multiple SSIDs to what is each SSID typically mapped in order to provide traffic management separately for each SSID?

A. VLAN B. Access Category C. DSCP tags D. 802.1p markings

Correct Answer: A

Question 11

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

A. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result B. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11 C. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken D. Purchase and deploy new APs from a different vendor
