Computer Networks - OSI and TCP/IP Models
You need to design a system that logs the source IP address at the Network layer during encapsulation and removes only the Data Link header during decapsulation. Which approach is correct?

hard📝 Application Q8 of 15
Step-by-Step Solution
Solution:
Step 1: Understand header order
IP header is part of Network layer and is added before Data Link header during encapsulation.Step 2: Match removal requirement
Removing only Data Link header means leaving IP header intact for logging.Final Answer:
Add IP header before Data Link header; remove only Data Link header on receive -> Option AQuick Check:
Correct header order and selective removal needed [OK]
Quick Trick: Network layer header before Data Link; remove only Data Link [OK]
Common Mistakes:
MISTAKES- Adding IP header after Data Link
- Removing all headers instead of selective
- Confusing header order
