ICND1 Routing Technologies & Protocols — Questions and Answers
Question 1: Which protocol is used to determine the best path for data to travel in a network?
- ARP
- OSPF and RIP (Correct answer)
- DHCP
- DNS
Correct answer: OSPF and RIP
OSPF (Open Shortest Path First) and RIP (Routing Information Protocol) are both routing protocols used by routers to determine the most efficient path for data packets to travel across a network. They achieve this by exchanging routing information with other routers and calculating the best routes based on various metrics, such as hop count or link cost. These protocols are essential for efficient data delivery in complex networks.
Question 2: What is the primary function of the Routing Information Protocol (RIP)?
- To assign IP addresses.
- To determine the best route based on hop count (Correct answer)
- To manage IP addressing.
- To assign MAC addresses.
Correct answer: To determine the best route based on hop count
RIP (Routing Information Protocol) is a distance-vector routing protocol that determines the best path for data by counting the number of hops (routers) between the source and destination. The path with the fewest hops is considered the best route. While simpler to implement, RIP's reliance solely on hop count can sometimes lead to suboptimal routing decisions compared to more advanced protocols.
