문제2

What differences exist between VLANs in wireless and wired domains?
Response:

A. 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.

B. 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.

C. 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.

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

정답: B

문제3

What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags?

A. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag reader to communicate tag information to the

B. With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.

C. When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.

D. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.

정답: A

문제4

Given: As the wireless network administrator for XYZ Company, you are planning to upgrade your aging wireless network infrastructure, as well as some clients, to support 802.11ac.
In your research, you have discovered that your new wireless client devices and infrastructure are 802.11ac, WMM, and WMM-PS certified by the Wi-Fi Alliance. Some of your existing client devices are 802.11a/b/g devices that do not support WMM.
Given this information, what scenario is possible when your company's employees begin using both types of client devices on the new WLAN?
Response:

A. WMM-PS enabled APs will allow both WMM-PS and non-WMM-PS stations to use the triggerand- delivery mechanism, but WMM-PS stations will g

B. Performance and battery life will be inconsistent between WMM-PS and non-WMM-PS client devices when used with applications that support WMM-PS.

C. All WMM-PS certified client devices will be prevented from utilizing WMM-PS features until all stations in use on the wireless medium are WMM-PS certified.

D. The WLAN infrastructure will set the dozing times of the WMM-PS certified client devices based upon their WMM access category, while the non-WMM-PS client devices will continue to use PSPoll frames.

정답: B

문제5

Given A project parameter defines a requirement or constraint (or a project that can be defined before any file imports or design actions. What is an example of a project parameter commonly available in WLAN design software?

A. Floor plan

B. Minimum required signal strength

C. AP type selection

D. AP locations

정답: B

문제6

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 customer laptop does not support Transmit Beamforming

B. The AP is configured to use channel 36

C. The AP is on channel 144

D. Their laptops are SISO clients

정답: C

문제7

What are three potential benefits when an organization lets their employees bring their own device onto the company s network"?

A. Enhanced productivity Increased costs, and Decreased satisfaction

B. Enhanced productivity. Increased costs, and Increased satisfaction

C. increased security Enhanced productivity, and Decreased attack surface

D. Enhanced productivity Decreased costs and Increased satisfaction

정답: D

문제8

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?

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

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

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.

정답: A

문제9

A wireless network with fewer APs at higher power levels to cover a large area is said to be which of the following?
Response:

A. Coverage based

B. Capacity based

C. Destined for failure

D. Ideal for roaming

정답: A

문제10

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?

A. No more than 8% PER max should be acceptable

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

C. No more than 4% PER max should be acceptable

D. No more than 1% PER max should be acceptable

정답: A

문제11

What architecture suffers the biggest limitation for sharing control information across APs?
Response:

A. Centralized

B. Independent autonomous

C. Distributed

D. Cooperative autonomous

E. Controller

정답: B

문제12

What is the purpose of Friis transmission equation [ (LdB) = 20 log(d) + 20 log (f) - 27.55 ]?

A. Calculate earth bulge to determine minimum antenna height

B. Calculate the loss experienced between the intentional radiator and antenna

C. Calculate receive sensitivity for an 802.11 radio/antenna pair

D. Calculate RF path loss in free space

정답: D

문제13

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. Deploy all of the APs as they're shown in the predictive design and perform a passive site survey.

B. Use a client device positioned where the APs will be installed and measure the signal from the client device.

C. Perform an AP-on-a-Stick survey using AP locations based upon the predictive design to confirm each AP's placement.

D. Deploy all of the APs as they're shown in the predictive design and perform an active site survey.

문제14

During an RFP analysis, one of the vendors mentioned that you'll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for
802.11ac and 802.11ax, which both offer data rates over 1Gbps. Why is this not sound advice?

A. Management overhead that is normal in WLANs will reduce the throughput of the client devices

B. Because 802.11ac only supports one spatial stream

C. Because neither of the technologies support data rates over 1Gbps

D. Because 802.11ax doesn't support channel bonding
