What does redundancy mean in the context of Internet routing?

Question

Multiple paths exist between any two points

For any two points on the Internet, there exists only one path between them

Data sent over the Internet is sent to the router with the lowest cost.

If a single router on a network breaks, the entire network fails.

Answer 1

In the context of Internet routing, the correct understanding of redundancy is:

Multiple paths exist between any two points.

Redundancy in Internet routing refers to the practice of having multiple pathways for data to travel between two points. This allows for alternative routes to be used in case one path becomes unavailable due to a failure in a router or other network component, thus maintaining network reliability and performance. The other options do not accurately describe redundancy in this context.
