Why should band steering algorithms allow stations to connect to the 2.4 GHz band after some number of ignored Probe Requests?

A.

Because the FCC requires it.

B.

Because some clients are persistent clients that will not move on to the 5 GHz band.

C.

Because the 802.11 standard requires it.

D.

Because the AP will experience a buffer overflow if they do not eventually respond with a Probe Response.

Your customer requires a security solution in which client credentials are used and the authentication server must have a certificate with optional client certificate use. Which EAP method would be the best fit for their requirement?

A.

EAP-FAST

B.

EAP-TTLS

C.

EAP-TLS

D.

LEAP

During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine. What’s the likely cause of this issue?

A.

Employees are using their cell data instead of using the Wi-Fi

B.

The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch

C.

Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band

D.

Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band

When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?

A.

Frequency Selection

B.

Roaming

C.

AP vendor

D.

Band steering

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.

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?

A.

11 dBm

B.

6.25 mW

C.

125 mW

D.

17 dBm

What advantage provided by 802.11n and 802.11ac is not usable in 1X1:1 low-end client devices?

A.

Channel bonding

B.

MCS data rates

C.

Maximal Ratio Combining

D.

Mandatory data rates

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
