Match List I with List II
List IList II
A. Data Link LayerI. True end-to-end layer
B. Network LayerII. Token Management
C. Transport LayerIII. Produce billing information
D. Session LayerIV. Piggybacking
Choose the correct answer from the options given below:

Solution

Data Link Layer supports piggybacking in flow and error control. So, $A-IV$.

Network Layer can produce billing or accounting information for network usage. So, $B-III$.

Transport Layer is the true end-to-end layer because it provides process-to-process communication. So, $C-I$.

Session Layer handles token management and dialog control. So, $D-II$.

Final matching is $A-IV,\ B-III,\ C-I,\ D-II$.
