A. session
B. transport
C. network
D. data link
E. physical

Answer: D 

Q 2.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

 Answer: A,D

Q 3.A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network.How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?
