ICT Networking Models and Protocols 4

Question 1

Which TCP/IP model layer is responsible for moving bits across the physical medium?

Accepted Answer

Network Access layer

Answer

The Network Access layer (also called Link layer) in the TCP/IP model handles physical transmission and data framing, equivalent to OSI Layers 1 and 2.

Question 2

Port 443 is associated with which protocol?

Accepted Answer

HTTPS

Answer

HTTPS (HTTP Secure) uses port 443 for encrypted web communication via TLS/SSL.

Question 3

Which routing protocol is classified as a distance-vector protocol?

Accepted Answer

RIP

Answer

RIP (Routing Information Protocol) is a distance-vector protocol that uses hop count as its metric and shares its entire routing table with neighbors.

Question 4

What is the maximum hop count allowed by RIPv2 before a route is considered unreachable?

Accepted Answer

15

Answer

RIPv2 has a maximum hop count of 15; a hop count of 16 is considered infinite and marks the route as unreachable.

Question 5

Which of the following is a link-state routing protocol that uses Dijkstra's algorithm?

Accepted Answer

OSPF

Answer

OSPF (Open Shortest Path First) is a link-state protocol that builds a complete network topology map and uses Dijkstra's shortest path algorithm.
