5. Question : Two connected routers are configured only with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table?
Student Answer:The updated information will be added to the existing routing table.
The update will be ignored and no further action will occur.
The updated information will replace the existing routing table entry.
The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence.
