B is incorrect; as the DLCI are significant to just the two routers involved in the exchange of information it is not proper to refer to globally significant DLCI.
C is incorrect; locally significant LMI is not the answer. LMIs are responsible for managing the connection between the routers and not the assignment of numbers.
D is incorrect; globally significant LMI is not the answer. LMIs are responsible for managing the connection between the routers and not the assignment of numbers.

Q. 8
During encapsulation in which order is information packaged?
A.Data, Packet, Segment, Frame
B.Segment, Data, Packet, Frame
C.Data, Segment, Packet, Frame
D.Packet, Data, Segment, frame
Answer: C.
Explanation: Data encapsulation is a process in which information is wrapped in the data section of another protocol. In the OSI model each layer encapsulates the layer immediately above as the data flows down the protocol stack. The order of encapsulation is
1. | Application/Presentation/Session | DATA |
2. Transport | SEGMENT | |
3. | Network | PACKET |
4. Data Link | FRAMES | |
5. | Physical | BITS |
Incorrect Answers:
A is incorrect; with Data, Packet, Segment, Frame; packet and segment are inverted. B is incorrect; with Segment, Data, Packet, Frame; data and segment are inverted.
D is incorrect; with Packet, Data, Segment, frame; the only information package in the proper order is frame.
