What action should be taken after implementing a WLAN based on the design developed from the site survey process?

A. Post-installation survey

B. Requirements analysis

C. Gathering facility documentation

D. Design the infrastructure services

Assume that your network operates in a regulatory domain that allows use of the entire 5 GHz space allowed in the 802.11ac amendment. In your upcoming 802.11ac deployment, you would like to take advantage of the performance improvements that result from channel bonding. However, after extensive testing, you have determined that your mission-critical WLAN should not use channels requiring DFS support.

Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how many non-overlapping 40 MHz channels will your system be able to use?

A. 2

B. 3

C. 4

D. 6

ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems. In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?

A. Have only guest access on the 5 GHz channels.

B. Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.

C. Use captive portals for guest authentication in 5 GHz.

D. Implement WPA-PSK everywhere in the network.

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

Response:

A. Static electricity

B. Brownouts

C. Lightning surge suppression

D. A/C spikes

During a validation site survey, you realize that the installers mounted some of the APs above the ceiling. They said that this was a request from the building architect due to aesthetics constraints.

During the requirements gathering, you weren't advised about any aesthetics constraints from the main stakeholder of the project. What should you do in this case?

Response:

A. Remove all external antennas and use only the internal antennas to reduce multipath.

B. Advise the stakeholder that WLAN performance requirements will not be met and a new design process will be needed to meet the requirements.

C. Leave it as it is and allow automatic channel management to correct any issues.

D. Increase the output power on all APs by 6 dB immediately.

Which type of authentication and encryption method is mandatory for Voice Enterprise certified devices as specified by the Wi-Fi Alliance?

A. WPA2/AES Personal

B. WPA2/TKIP Enterprise

C. WPA2/AES Enterprise

D. WPA/TKIP Personal

You are working on a VoWLAN design with your customer's wired networking team. How many distinct priority levels do you expect for the voice applications?

A. 1 priority level, but 2 queues (one for uplink traffic, one for downlink traffic)

B. 1 priority level per client and AP pair, so the total number depends on the expected number of clients

C. 1 priority level for voice RTP, 1 priority level for voice control and RTCP

D. 1 priority level for VoWLAN client traffic, 1 priority level for wired VoIP client traffic

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?

A. 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.

B. 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.

C. 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.

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

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

After designing and deploying a WLAN infrastructure, you realized the CCI is causing poor performance in the 2.4 GHz band. Primarily, you've designed the

WLAN for 5 GHz and 2.4 GHz as a best effort. You found out that the implementers didn't follow your guidelines when configuring the WLAN infrastructure. What can you do to minimize as much as possible the CCI impact in the 2.4 GHz band?

A. Add more APs to the infrastructure

B. Increase the transmit power on all APs

C. Turn-off 2.4 GHz radios on some APs

D. Use all channels available in the 2.4 GHz band
