Which of the following best describes how a router forwards a packet to a destination on a different network?

It uses the destination MAC address to determine the next hop

It broadcasts the packet to all interfaces

It looks up the destination IP address in its routing table and forwards the packet to the next hop

It encapsulates the packet in a new frame with the source MAC address

Why is fast convergence important in a network?

It reduces the time that packets are dropped or routed incorrectly after a topology change

It increases the bandwidth available on each link

It ensures all routers use the same routing protocol

It eliminates the need for routing protocols

What is the primary purpose of route summarization?

To reduce the size of routing tables and improve routing efficiency

To ensure all routes are advertised to all routers

To provide redundancy by creating multiple paths to the same destination

To increase the number of routes in the routing table

A network administrator is troubleshooting a routing issue. The routing table on a router shows two routes to the 10.10.0.0/16 network. One route was learned via OSPF with an administrative distance of 110, and the other via static configuration with an administrative distance of 1. Which route will the router use to forward packets to 10.10.0.0/16?

The route with the lower metric, regardless of administrative distance.

The OSPF route, because it is dynamically learned and more current.

The static route, because it has a lower administrative distance.

The router will load-balance traffic between both routes.
