Question 1

Which of the following statements describe the network shown in the graphic? (Choose two)

A. There are two broadcast domains in the network.
B. There are four broadcast domains in the network.
C. There are six broadcast domains in the network.
D. There are four collision domains in the network.
E. There are five collision domains in the network.
F. There are seven collision domains in the network.

Answer 1

1. There are two broadcast domains in the network.
2. There are seven collision domains in the network.

Question 2

Which of the following correctly describe steps in the OSI data encapsulation process? (Choose two)

• The transport layer divides a data stream into segments and may add reliability and flow control information.
• The data link layer adds physical source and destination addresses and an FCS to the segment.
• Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.
• Packets are created when the network layer adds Layer 3 addresses and control information to a segment.
• The presentation layer translates bits into voltages for transmission across the physical link.

Answer 2

1. The transport layer divides a data stream into segments and may add reliability and flow control information.
2. Packets are created when the network layer adds Layer 3 addresses and control information to a segment.

Question 3

A network interface port has collision detection and carrier sensing enabled on a shared twisted pair network. From this statement, what is known about the network interface port?

• This is a 10 Mb/s switch port.
• This is a 100 Mb/s switch port.
• This is an Ethernet port operating at half duplex.
• This is an Ethernet port operating at full duplex.
• This is a port on a network interface card in a PC.

Answer 3

This is an Ethernet port operating at half duplex.
