Match the following: P. SMTP, Q. BGP, R. TCP, S. PPP — with layers: 1. Application layer, 2. Transport layer, 3. Data link layer, 4. Network layer, 5. Physical layer.
- AP-2, Q-1, R-3, S-5
- P-1, Q-4, R-2, S-3
- CP-1, Q-4, R-2, S-5
- DP-2, Q-4, R-1, S-3
Explanation
SMTP is an Application-layer protocol (1). BGP is a routing protocol, classified at the Network layer (4). TCP is the classic Transport-layer protocol (2). PPP (Point-to-Point Protocol) operates at the Data Link layer (3). So P-1, Q-4, R-2, S-3.
