Which two methods can be used to identify the next hop in a static route?

(Choose two.)

• Destination interface

• next hop IP address

• Destination network address

• Exit interface

• source IP address

What is a characteristic of a default static route? ​

• It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route

• It uses a single network address to send multiple static routes to one destination address.

• It backs up a route already discovered by a dynamic routing protocol

• It is configured with a higher administrative distance that is the original dynamic routing protocol

What table does a router use to determine how to forward an IP packet?

• ARP table

• MAC address table

• neighbour cache

• routing table

What action will a router take on a packet with a destination IP address that is on a remote network?

• It will forward the packet directly to the device with the destination IP address of the packet

• It will forward the packet to a next-hop router

• It will forward the packet to an ethernet switch

• It will drop the packet

Which of the following routes may be found in a routing table?

(Choose all that apply.)

• Directly connected networks

• Static routes

• Dynamic routing protocol routes

• Default route

Which routing table principle is NOT correct?

• Every router makes it decision alone, based on the information is has in its own routing table.

• The fact that one router has certain information in its routing table does not mean that other routers have the same information.

• Routing information about a path from one network to another also providies routing information about the reverse, or return, path.

Which two route sources have the ability to automatically discover a new best path when there is a change in the topology? (Choose two.)

• Static route.

• OSPF

• EIGRP

• Default route.

What metric is used by OSPF to determine the best path?

• Hop count

• Cost

• Bandwidth and delay

• Decided by the network administrator

What are two functions of dynamic routing protocols?

(Choose two.)

• To discover the network

• To chose the path that is specified by the administrator.

• To assure low router overhead.

• To maintain routing tables

What is the correct order in the steps for Link-State operation?

• 1. 1. Establish neighbour adjacencies

  2. 2. Exchange link-state Advertisements

  3. 3. Build the topology table

  4. 4. Execute the SPF algorithm
