medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Identify encapsulation order
Headers are added from Application (HTTP) down to Data Link (Ethernet).Step 2: Determine decapsulation order
Headers are removed in reverse order; the Application header (HTTP) is processed last.Final Answer:
HTTP -> Option DQuick Check:
Last header processed = Application layer header [OK]
Quick Trick: Last header processed is Application layer [OK]
Common Mistakes:
MISTAKES- Choosing Ethernet as last
- Mixing header processing order
- Confusing header names
