QUESTION 8
At which of the following layers do frames exist? (Select TWO).
A. OSI model Data link layer
B. TCP/IP model Network Interface layer
C. OSI model Physical layer
D. OSI model Network layer
E. TCP/IP model Internet layer
Correct Answer: AB
Explanation
Explanation/Reference:
The data link layer is concerned with local delivery of frames between devices on the same LAN. Data-link frames, as these protocol data units are called, do not cross the boundaries of a local network. Inter-network routing and global addressing are higher layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ultimate destination.
