Question # 51

You performed a site survey with two USB Wi-Fi adapters using a special driver written for the site survey software. After deployment, you realized

that the client devices used by your customer are getting lower RSSI values than that shown during your site survey. What is the most likely reason

for this result?

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

The transmit power on the APs is higher than needed.

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

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

Question # 52

What differences exist between VLANs in wireless and wired domains?

Response:

Wireless VLANs are not effective for segmenting the available services and network permissions available to clients. Wired VLANs are effective for this purpose.

Wireless VLANs are never carried in 802.11 frames that cross the wireless medium. VLAN identifiers are always carried in Ethernet frames to indicate the proper VLAN.

Wireless VLANs do not always segment traffic into separate broadcast domains on the wireless medium. Wired VLANs do segment broadcast domains on the wired network.

Wireless VLANs are ineffective for utilizing a single set of infrastructure equipment to provide different services to different client groups. Wired VLANs are effective for this purpose.

Question # 53

You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an

acceptable packet error rate value to still provide acceptable call quality?

There should be 0% error in a VoWLAN type of deployment

No more than 1% PER max should be acceptable

No more than 4% PER max should be acceptable

No more than 8% PER max should be acceptable

Question # 54

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:

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

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

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

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

Question # 55

What are methods of providing RF high availability?

Response:

Power APs to maximum power.

Use the HSRP/VRRP protocol.

Deploy using 100 percent overlap.

Deploy 802.3af.

Use dual spectrums.

Question # 56

During a post-validation assessment, you have configured a client for 802.1X/EAP but it is not passing authentication. Which areas should you check in the WLAN configuration?

Response:

Whether the RADIUS server is online and configured for the matching port on the APs and WLAN controllers

Whether the RADIUS shared secret is properly configured on the supplicant and authentication server

Whether the authenticator is configured to support the EAP type(s) your client is configured for

Whether the client has a fully valid certificate

Question # 57

Which of the following is not a business requirement?

Response:

The new network design must improve employee productivity.

The new network design must cut operating expenses.

The new network design must make employees happy to come to work.

The new network design must provide support for 802.11n.

Question # 58

Which one of the following options would you consider a well-designed WLAN infrastructure when measuring RSSI Notse floor and SNR in a required area?

Low RSSI, Low Noise Floor Low SNR

High RSSI, Low Noise Floor High SNR

High RSSI, High Noise Floor Low SNR

Low RSSI, High Noise Floor Low SNR

Question # 59

A museum wants to offer Wi-Fi to its visitors. One of their requirements is to have the APs blend into the design of the museum. What should you do to meet this requirement?

Use a plastic cover that could blend in with the environment

Lock the AP inside of a metal box

Place the APs in between walls and I-beams

Use an 802.11b AP, so it looks old enough to be in a museum

Question # 60

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?

Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

Purchase and deploy new APs from a different vendor

Reconfigure the automatic channel assignment settings to use only channels 1, 6, and 11

Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result
