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

Correct Answer: E

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.

Correct Answer: C

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

Correct Answer: C

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.

Correct Answer: AD

• 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

Correct Answer: D
