A. 1 B. 7 C. 4 D. 2 QUESTION: 11 According to the IEEE 802.1x Standard, what is a "Supplicant"? A. a PAE requesting access to the network from an authenticator B. an entity providing Authorization services to an authenticator; may be located on the same device as the authenticator or be a remote device C. the protocol entity associated with a port (i.e., firmware) D. a point of attachment to a LAN, Usually a physical port, but may also be a logical port (i.e., 802.3ad aggregated link) QUESTION: 12 How many 802.1p priorities are defined by the IEEE 802.1D standard?

A. 128 bytes B. 60 bytes C. 64 bytes D. 46 bytes QUESTION: 15 Which groups of RMON does the Matrix C2 support? A. the C2 supports 4 groups of RMON (groups 1,2,3 and 9) B. the C2 supports all 9 groups of RMON C. the C2 supports 5 groups of RMON (groups 1,2,3, 4 and 9) D. the C2 supports 4 groups of RMON (groups 1,2,3 and 4) QUESTION: 16 Which statement best describes Weighted Fair Queuing? A. All frames are transmitted in a weighted first-in, first-out queue (the bigger the frame, the quicker it is transmitted). B. A lower priority queue cannot transmit until a higher priority queue is empty.

5 5 C. If frames have no assigned priority, the switch places them in a queue according to weighted parameters based on criticality. D. Higher priority frames may be buffered while lower priority frames use their allotted time to transmit. QUESTION: 17 How many router processes are permitted per DFE module?
