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 an active site survey.

B.

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

C.

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

D.

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

In a convention center, you have received complaints about the WLAN infrastructure. At this moment, the are only two APs in one auditorium.

After analyzing the situation, you determined that there are more client devices that the infrastructure was designed for. There are only two APs to support more than 300 devices using the Wi-Fi at the same time.

What should you do to make the Wi-Fi work as expected?

Response:

A.

Redesign the entire WLAN

B.

Upgrade the Ethernet connections to MultiGig

C.

Quickly add more APs

D.

Turn up the output power on the APs so that they can handle more clients

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

Response:

A.

Preventing guests from attempting to join the secured corporate network

B.

Obscuring the network name from potential attackers

C.

Minimizing help desk calls from users and guests attempting to join the wrong network

D.

Preventing legitimate corporate users from finding the guest network

Before performing a pre-deployment passive RF survey of a new deployment using survey mapping software, which of the following must be performed?

Response:

A.

Determining AP transmit power

B.

Scaling the map

C.

Selecting antennas

D.

Checking client DTPC settings

You deployed an AP and installed its antenna, and you now need to set the AP transmit power. Given a desired EIRP of 21 dBm, and an antenna

gain of 5.85 dBd connected through 25 feet of cable with a loss specification of 4 dB/100 feet.

Assuming that there is no significant loss from the connectors, what should be the transmit power level for this AP?

A.

10 mW

B.

14 mW

C.

20 mW

D.

25 mW

As a device starts to shift to lower PHY rates, what factors usually influence a device decision to shift to lower PHY rates?(Choose all that apply.)

Response:

A.

Signal degradation

B.

Packet loss

C.

Interference

D.

Retransmissions

When performing a roaming test and packet capture at the same time, what are two particular frames that will be present when roaming between two APs is successful?

A.

Beacon and DTIM

B.

Probe Request and Probe Response

C.

Association Request and Association Response

D.

Reassociation Request and Reassociation Response

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and

go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used

efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine.

Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to

use the available addresses as efficiently as possible.

What setting would be most effective at achieving this design task?

A.

Set the RTS threshold to 2346 bytes

B.

Set the inactive wireless client timeout (client age-out) to 5 minutes

C.

Set the maximum client limit per radio to 64

D.

Set the DHCP lease for this pool to 20 minutes

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 not an effective way to utilize a single set of infrastructure equipment to provide different services to different client groups. Wired VLANs are effective for this purpose.

Install technicians are deploying a multi-floor WLAN that you have designed They have finished the first floor and all APs on that floor are powered on and functioning No APs on any other floors have been deployed at this time You are considering performing a post-deployment site survey of the first floor immediately to validate proper implementation What statement is true about this site survey if you perform it?

A.

It will miss any impact on the WLAN caused by APs on other floors

B.

It will show you how the first floor will function after all other floors are deployed

C.

It will not work because the controllers cannot function properly until all APs licensed lo the controller are operational

D.

It will result in a complete set of data informing you how clients will function after the entire WLAN is implemented
