---------------------------------------------------------------------
41
Which of the following are characteristics of IP? (Choose three.)

connection-oriented protocol

connectionless protocol*

reliable protocol

42
Which of the following describe the token-passing logical topology? (Choose two.)

*FDDI is an example of a token-passing network.

Token-passing logical topologies must also be physical ring topologies.

One of the disadvantages of the token-passing logical topology is the high collision rate.

Computers transmit data after "listening" to the wire to detect other traffic.

*Computers are allowed to transmit data only when they possess a token.
