Question

In the context of internet routing, redundancy means
_ (2 points)
• 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 tails.
Which statement below is a benefit of the fault-tolerant nature of internet routing?
(2 points)
• The ability to use a hierarchical naming system to avoid naming conflicts.
The ability to provide data transmission even when some connections between routers have failed.
• The ability to resolve errors in domain name system (DNS) lookups.
The ability to use multiple protocols such as hypertext transfer protocol (H T T P), Internet protocol (IP), and simple mail transfer protocol (SMTP) to transfer data.

Answer 1

In the context of internet routing, redundancy means:

**• Multiple paths exist between any two points.**

This option describes the ability to have alternative routes for data to travel, which is a key aspect of the redundancy in internet routing.

As for the benefit of the fault-tolerant nature of internet routing, the correct statement is:

**• The ability to provide data transmission even when some connections between routers have failed.**

This highlights the fault-tolerant aspect of the internet routing system, which allows for continued operation despite certain failures in the network infrastructure.
