Routing Table Quiz

What are the various sources from which routing table entries come?

• Firewalls, Switches, Routers

• Wireless networks, Fiber optic cables, Satellite communication

• Connected networks, Static routes, Dynamic routing protocols

• LAN, WAN, MAN

In a routing table, what is the purpose of Level 1 routes?

• Function as Default route, Supernet route, Network route

• Contain next-hop address or exit interface information

• Contain subnet mask equal to or less than the classful mask of the network address

• Automatically create parent routes

What is the reason for the hierarchical structure of the Cisco IP routing table?

• To slow down the lookup process

• To confuse network administrators

• To speed up the lookup process

• To increase the number of routing entries

When using classful routing behavior, what happens if there is no match with any level 2 child routes of the parent?

• Router looks beyond child routes for a match

• Router searches for a lesser match

• Packet is dropped

• Packet is forwarded

What is the significance of the 'ip classless' command in routing behavior?

• Stops the router from forwarding packets

• Indicates classful routing behavior

• Enables the router to search beyond child routes for a match

• Indicates classless routing behavior

In the routing table lookup process, what is the purpose of examining level 1 routes?

• To determine the classful routing behavior

• To search for the best match with the packet's destination IP

• To drop the packet if no match is found

• To configure supernet routes

What is the outcome if a match is found between the destination IP and a level 1 parent route in the routing table?

• Router searches for a default route

• Packet is forwarded

• Packet is dropped

• Router examines level 2 child routes

Why is it recommended to use classless routing behavior?

• To enable the use of supernet and default routes

• To confuse network administrators

• To slow down the lookup process

• To increase the number of child routes

What is the purpose of the 'no ip classless' command in routing behavior?

• Indicates classful routing behavior

• Indicates classless routing behavior

• Enables the router to search beyond child routes for a match

• Stops the router from forwarding packets

How does the router determine the best match in the routing table lookup process?

• By configuring supernet routes

• By examining only the child routes

• By searching for the longest match with the destination IP address

• By dropping the packet if no match is found
