Question

A) Child route > Level 1 route > Parent route > Default route

B) Default route > Parent route > Level 1 route > Child route

C) Level 1 route > Child route > Default route > Parent route

D) Child route > Default route > Level 1 route > Parent route

Answer 1

The correct order of routes in a hierarchical routing system is child route, level 1 route, parent route, default route.

Step-by-step explanation:

The correct order of routes in a hierarchical routing system is:

1. Child route (most specific)
2. Level 1 route
3. Parent route
4. Default route (most general)

Routing is the process of determining the best path for network traffic to reach its destination. In a hierarchical routing system, routes are organized in a hierarchy, with child routes being more specific and covering smaller address ranges, and parent routes being less specific and covering larger address ranges.

When a routing device receives an incoming packet, it looks for the most specific route that matches the destination address of the packet. If a child route matches the destination address, it is chosen as the best path. If no child routes match, the device looks for a level 1 route. If no level 1 routes match, it then looks for a parent route. Finally, if no parent routes match, the device uses the default route as the last resort.
