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?

A.

Lock the AP inside of a metal box

B.

Place the APs in between walls and I-beams

C.

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

D.

Use a plastic cover that could blend in with the environment

What is the purpose of a Physical Installation Guide document?

A.

To inform the Install technicians of WLAN frame exchanges and communication methods

B.

To provide clear instructions on the locations and mounting methods, and possible configuration steps for APs

C.

To provide sources for purchasing the equipment needed to implement the WLAN

D.

To prove that the WLAN meets the organization's requirements

What are some common problems with short (12 or fewer characters) ASCII passphrases in WPA/WPA2-Personal networks?

Response:

A.

They are more susceptible to dictionary attacks than longer passphrases.

B.

They lead to weak group keys in a BSS.

C.

They only produce a 64-bit PMK instead of a 256-bit PMK.

D.

Very few AP and client vendors support entry of an ASCII-based passphrase.

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

What roaming technology uses stored keys at the APs for roam back if a client STA returns after having roamed away?

Response:

A.

SCA roaming

B.

Preauthentication

C.

OKC

D.

PMK caching

For what purposes are VPNs typically used in modern WLANs?(Choose all that apply.)

Response:

A.

Remote AP tunneling to a corporate WLAN controller or VPN concentrator

B.

Client device connectivity to corporate resources from unsecured public networks

C.

Initial 802.11 authentication with the AP and subsequent data encryption

D.

Tunneling APs and WLAN controllers to cloud-based management platforms

E.

Tunneling APs and WLAN controllers to RADIUS and token servers

F.

Bridging client connectivity in ad hoc networks

What limitation exists when WMM is not enabled on an 802.11n WLAN?

A.

802.11 QoS will not be available

B.

The maximum channel-width will be 20MHz

C.

EDCA values will change

D.

Only two ACs will be available

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're preparing to perform a site survey for a company that processes meat. Some areas are restricted due to high-security. What do you have to

do in order to proceed with the site survey?

A.

Gain appropriate access and clearance to perform the site survey.

B.

Gain meat processing access certification from the FDA.

C.

Ensure that you and your team are using food industry approved USB adapters for the survey.

D.

Just begin the survey, they will understand

What is the best method of gathering attenuation measurements from any building materials or objects?

A.

After measuring the RSSI in free space 5 meters (16.5 feet) apart, put an AP 4 meters (13 feet) away from the wall or object on one side

and your measuring device 0.67 meters (2 feet) away from the wall or object on the other side. Take measurement and compare the

difference.

B.

Use the pre-built attenuation values in the predictive design tool.

C.

After measuring the RSSI in free space 1 meter (3 feet) apart, put an AP 0.32 meters (1 feet) away from the wall or object on the other side.

Take measurements and compare the difference.

D.

Look on the Internet for attenuation values for each one of the materials that might attenuate the Wi-Fi signal using the material provider's

websites.
