The Cisco Certified Network Associate (CCNA) program is here to give you the tools needed to gain an understanding on the inner workings of networking theory, and today we’ll be taking a look at some of the topics explored in the curriculum. Welcome to an interesting quiz on CCNA Chapter 8!
RIPV1
RIP V2
EIGRP
OSPF
Child routes are present in the routing table.
The command ip classless is enabled on the router
A classless routing protocol has been configured on the router
Routing table entries have a next-hop IP address and an exit interface for each child route
0.0.0.0
255.255.0.0
255.255.255.0
255.255.255.255
Drop the packet
Use the default route
Forward the packet via the route to 10.16.1.0
Forward the packet via the route to 10.16.1.64
EIGRP is being used
There is at least one parent and one child route
192.168.2.0,192.168.3.0 and 192.168.40 networks are child routes
Traffic going to 172.16.3.0 will be directed to s 0/0/1
They are dropped
Sent to default gateway
Forward out interface serial 0/0/1
Forward out interface FastEthernet 0/0
The router will have to perform recursive lookups to forward a packet destined for 192.168.2.213 /24
The parent route for these networks was removed from the routing table
A route to 192.168.0.0/25 would be classified as a supernet route for the route for the routes listed in the routing table .
All of the routes listed are network routes
Drop the packet
Send packet out serial 0/0/1
Send packet to network 0.0.0.0
Send packet out FastEthernet 0/0
The route with the highest bandwidth
The route with the smallest Administrative Distance
The route with the longest address and mask match to the destination
The route with the best combination of Administrative Distance and lowest cost

The router will only support classful IP addressing
The router will only support classful routing protocols
The router will use a default route,if present when a matching route is not found in the routing table.
The router will assume it has knowledge of all subnets in the network and will not search beyond child routes for a better match .
Issue the ip defauly network command
Use a classful routing protocol such as RIPV1
Enable either OSPF or ISIS as the routing protocol
Issue the ip classless command
Do nothing,ip classless is on by default
Metric
Route prefix
Update timer
Administrative distance
172.16.0.0/16
172.16.0.0/24
172.16.0.0/30
172.16.1.0/16
172.16. 1.0/24
Ip classless
No ip classless
Ip default 0 network 0.0.0.0
Ip default-gatewat 172.16.254.1
Ip route 0.0.0.0 0.0.0.0 serial 0/0/1
172.16.1.0/25 because it is the first ultimate route
0.0.0.0/0 because it is the lowest network number
172.16.0.0/25 because it is the first level 1 route
172.18.0.0/15 beacuse it has the shortest mask
