Question 1
Which layer in the OSI reference model is responsible for determining the availability of the receiving program and checking to see if enough resources exist for that communication?
- A: transport
- B: network
- C: presentation
- D: session
- E: application
Question 2
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?
- A: This is a 10 Mb/s switch port.
- B: This is a 100 Mb/s switch port.
- C: This is an Ethernet port operating at half duplex.
- D: This is an Ethernet port operating at full duplex.
- E: This is a port on a network interface card in a PC.
Question 3
A receiving host computes the checksum on a frame and determines that the frame is damaged. The frame is then discarded. At which OSI layer did this happen?
- A: physical
- B: session
- C: data link
- D: transport
- E: network
Question 4
Which of the following correctly describe steps in the OSI data encapsulation process? (Choose two)
- A: The transport layer divides a data stream into segments and may add reliability and flow control information.
- B: The data link layer adds physical source and destination addresses and an FCS to the segment.
- C: Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information.
- D: Packets are created when the network layer adds Layer 3 addresses and control information to a segment.
- E: The presentation layer translates bits into voltages for transmission across the physical link.
Question 5
Host A is communicating with the server. What will be the source MAC address of the frames received by Host A from the server?
- A: the MAC address of the server network interface
- B: the MAC address of host A
- C: the MAC address of router interface e1
- D: the MAC address of router interface e0
