Question

(1) The sublayer is responsible for CSMA/CD operation. Select one: a. Logical Link Control (LLC) b. Medium Access Control (MAC) c. Physical Layer Management d. Data Link Layer (2) Carrier Sense Multiple Access (CSMA) method was developed to increase the of local area networks. Select one: a. collision b. performance d. number of station c. transmission time (3) In Carrier Sense Multiple Access/Collision Detection (CSMA/CD), sending station must detect collisions by "listening" to the medium for at least b. one-way propagation time d. round-trip propagation time a. one-way frame time c. round-trip frame time (4) The MAC scheme, CSMA/CD, imposes a restriction on the b. one-way propagation time d. number of stations a. collision time c. frame size (5) Assume a station sends an Ethernet frame to A7:87:10:DD:66:85. What is the binary format of this Ethernet address and which station(s) can receive this frame? Select one: a. 10100111:10000111,00010000;11011101:01100110;10000101; single station b. 10100111:10000111:00010000;11011101:01100110;10000101; multiple stations c. 10100110:10000011:00010000;11011101 01100110;10000101; all stations d. 10100110:10000011,00010000;11011101:01100110;10000101; no stations (6) An Ethernet destination address is 07:01:02:03:04:05, then this is a address.
