QUESTION 93
Which type of trunk is required in order to connect a fax machine to a PBX?
A. intra-office
B. Foreign Exchange Office
C. central office
D. Foreign Exchange Station
E. inter-office
Correct Answer: D
Section: Voice Video Explanation

Foreign Exchange Station (FXS) provides a connection from a switch to an analog endpoint
device such as traditional telephones or fax machines. It provides line power, dial tone, and ring.

Foreign Exchange Office (FXO) allows a switch such as a PBX to us a standard analog connection
(FXS) from the PSTN or from another switch. In this case the PBX is emulating an endpoint device.
Because this is a standard endpoint connection it uses two-wire connections just like a standard phone and
often uses an RJ-11 connector interface.

QUESTION 95
Which two of these represent a best practice implementation of a Split MAC LWAPP deployment in a Cisco Unified Wireless Network? (Choose two.)
A. Each wireless client authentication type maps to a unique SSID which in turn maps to a unique VLAN.
B. 802.1Q trunking extends from the wired infrastructure to the access point for translation into SSID(s).
C. 802.1Q trunking extends from the wired infrastructure to a wireless LAN controller for translation into SSID(s).
D. Each wireless client authentication type maps to a shared SSID which in turn maps to a common shared VLAN.
E. Each wireless client authentication type maps to a unique SSID which in turn maps to a common shared VLAN.
F. 802.1Q trunking extends from the wired infrastructure to a wireless LAN controller. Then the 802.1Q packet is encapsulated in LWAPP and sent to the access point for transmission over the SSID(s).
Correct Answer: AC
Section: Wireless Explanation

Cisco Unified Wireless Network Split-MAC Architecture

With the Cisco UWN split-MAC operation, the control and data messages are split. LWAPs communicate with the WLCs using control messages over the wired network. LWAPP or CAPWAP data messages are encapsulated and forwarded to and from wireless clients. The WLC manages multiple APs, providing configuration information and firmware updates as needed.
