You have been asked to design a WLAN for an organization. They will be replacing an existing WLAN Currently each AP operates 8 SSlDs on each radio What will you communicate with the organization so that they understand the need to reduce the number of SSlDs?

A.

implementing loo many SSIDs results in decreased data rates

B.

Implementing loo many SSIDs results in decreased throughput

C.

Implementing loo many SSIDs increases ACl in every scenario

D.

Implementing too many SSIDs reduces SNR in every scenario

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

Response:

A.

Independent autonomous

B.

Centralized

C.

Cooperative autonomous

D.

Controller

E.

Distributed

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.

Because neither of the technologies support data rates over 1Gbps

B.

Because 802.11ax doesn't support channel bonding

C.

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

D.

Because 802.11ac only supports one spatial stream

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.

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

C.

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

D.

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

What differences exist between VLANs in wireless and wired domains?

Response:

A.

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

B.

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.

C.

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.

D.

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.

An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB. Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?

Response:

A.

5 dBm

B.

0 dBm

C.

−5 dBm

D.

10 dBm

An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput. What is the most likely cause of this result?

Response:

A.

The APs are still using the 5 GHz lower band

B.

The clients were not upgraded

C.

APs are mounted on the wall

D.

APs are transmitting at a low transmit power

When deploying long-distance 802.11 bridge links (10 miles / 16 km), what parameter may be critical for improving data flow by reducing retries

caused by the long distances?

A.

The sequence control field value

B.

The acknowledgement timeout threshold

C.

The minimum transmit data rate value

D.

The CTS-to-self threshold

In most WLAN design tools, after defining project parameters or during the project creation wizard what action will you take before you can begin the actual design process?

A.

Place APs

B.

Define cabling

C.

Import a floor plan

D.

Define wall materials

When installing APs on high ceilings, what should be the most common PPE to be used?

A.

Hardhat, high visibility vest and body belt

B.

Glasses, gloves and jacket

C.

Clean suits, masks and glasses

D.

Clean suits, gloves and jacket
