Q. 187
Which statement about half-duplex Ethernet operation is true?
A. With half duplex transmission frames feed into a single cable in one direction at a time.
B. Half duplex transmission between stations is achieved by using point-to-point Ethernet and fast
Ethernet connection.
C. Half duplex transmission between stations is achieved by using point to multi point Ethernet and fast
Ethernet connection.
D. Half duplex Ethernet technology provides a transmit circuit connection wired directly to the receiver
circuit at the other end of the connection.
Answer: A
Explanation: Half-duplex only operates in one direction at a time on the cable.
Incorrect Answers:

Q. 188
What are true four ways that fast Ethernet that compares to 10baseT Ethernet (Choose four)
A. Fast Ethernet uses the same maximum transmission unit (MTU).
B. Fast Ethernet is based on an extension to the IEE 802.3 specifications.
C. Fast Ethernet uses the same media access control MAC mechanism.
D. Fast Ethernet preserves the frame format that is used by the 10BaseT Ethernet.
E. Fast Ethernet uses a speed increase 100 times to that of the 10BaseT Ethernet.
Answer: A, B, C, D
Explanation: Fast Ethernet shares a great deal of similarities with 10BaseT Ethernet. These similarities are the
same MTU, same MAC mechanism and frame format. Fast Ethernet is based on IEE 820.3u, which is an
extension to IEE 820.3.
