Question 1

You are designing a WLAN and nave been asked to recommend a security solution for the network The organization requires that 802 1X/EAP be implemented, but they do not have a PKI and do not wish to deploy one They suggest that mostly Windows clients. Apple phones and Android phones will be used What do you recommend?

A. Use FAP-TLS for the authentication solution B. Use EAP-PEAP for the authentication solution C. Use TKIPRC4 with a PSK D. Use CCMP AES with a PSK

Question 2

When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed?
Response:

A. Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported. B. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode. C. The router between the APs and the controller must be made aware of the APs as forwarding client STAs. D. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.

Question 4

What differences exist between VLANs in wireless and wired domains?
Response:

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

Question 11

You are site surveying a network for VoWiFi. You have positioned an AP for a manual survey and are moving away from the AP with a phone in Survey Mode in your hand and you are reading the RSSI value of the signal received from the AP. You have previously determined that the noise floor was approximately -94 dBm on this floor of the building. The phones documentation does not specify a recommended RSSI or SNR value for best performance.
Based on the information provided and the type of device (VoWiFi phone) you are deploying, what minimum RSSI should you plan for in all areas you are monitoring and where VoWiFi service is desired?

A. - 67 dBm B. - 75 dBm C. - 62 dBm D. - 72 dBm
