Multiple Choice Options
- A
Data Link layer
- B
Network layer
- C✓ Correct Option
Transport layer
- D
Session layer
Detailed Technical Solution & Explanation
The Transport Layer (Layer 4, such as TCP) is responsible for true end-to-end host-to-host process communication, managing segmentation, reassembly, error detection and recovery, flow control, and port-based multiplexing.
Option Analysis:
•
Option A (Data Link layer): Manages hop-to-hop framing between adjacent physical nodes.
•
Option B (Network layer): Manages host-to-host routing and IP packet delivery.
•
Option C (Transport layer): Correct. Provides reliable end-to-end transport and port-to-port multiplexing.
•
Option D (Session layer): Manages communication sessions and synchronization checkpoints.
