CWDP-304 Online Practice Questions and Answers

Which one of the following is an essential metric to measure when performing a survey and design for VoIP across WLANs?

A. Throughput rates above 50 Mbps

B. Data rates above 100 Mbps

C. Latency

D. PoE provided to wireless handsets

When performing an indoor predictive site survey to make the WLAN planning and design cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?

Response:

A. Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.

B. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.

C. All simulated APs should be set to 20 MHz channels only.

D. Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configured vendor AP/antenna combinations.

SSID hiding is not generally recommended because some frames require inclusion of the SSID. In what frames is the SSID always included?

Response:

A. Beacon

B. Association request

C. Probe response

D. Probe request

E. Authentication response

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?

Response:

A. Use a plastic cover that could blend in with the environment

B. Lock the AP inside of a metal box

C. Place the APs in between walls and I-beams

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

You are validating association capabilities from clients to an 802.1X/EAP secure SSID. The RADIUS server's IP address is 10.100.50.25 and the default RADIUS authentication port is used. When testing them, none of the clients are able to associate to the SSID. Troubleshooting the WLAN infrastructure, you found out that the server is up and the RADIUS service is up as well, but the authenticator is not able to communicate properly with the server. What's your next troubleshooting step?

A. Verify that the shared secret between the authenticator and the RADIUS server is correct

B. Reboot the clients

C. Reboot the server

D. Restart the RADIUS service

An enterprise customer is subject to the highest standards for network uptime. When designing their wireless network, you should consider which of the following?(Choose all that apply)

Response:

A. The failover of the wireless network only

B. The failover of the wired network only

C. The failover of the wireless and wired network

D. The physical aspects such as power and cabling

A controller-based WLAN infrastructure has its controller on a different subnet than its APs.

What device must be used to enable any communication between the Controller and the APs?

A. NTP server

B. Router

C. PoE Layer 2 switch

D. Wireless bridge

Given: A WLAN controller is connected to ABC Company's core layer 3 Ethernet switch with an IEEE 802.1Q trunk connection. The WLAN controller's native VLAN is VLAN 6 and its IP address is 10.0.14.2 /24. Lightweight APs supporting centralized forwarding are connected to the network on VLANs 7, 8, and 9, and they each build a Layer 3 tunnel back to the WLAN controller's IP address.

The dynamically assigned IP addresses received by each AP from a DHCP server will be ________________.

A. Associated with the VLAN on which they are connected.

B. Associated with the native VLAN of the WLAN controller.

C. Associated with VLAN 1, the default VLAN for new APs

D. Associated with a non-routable VLAN until the MAC address of the AP is removed from the controller's MAC filter

How are EAP messages transported over 802.11 wireless LANS? Response:

A. EAP-Fast

B. PEAP

C. EAPOL

D. EAP_TLS

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.
