The administrative distance of this route is 1.
192.168.1.2 is the address of an interface on this router.
This route will display as a directly connected network in the routing table.
Packets with a destination IP address of 192.168.1.2 will be forwarded to the 10.0.0.0/24 network first.

17.

Refer to the exhibit. Router1 and Router2 are running EIGRP. All interfaces are operational and packets can be forwarded between all networks. What information will be found in the routing table for Router1?
Router1 will have 6 directly connected networks.
The administrative distance of the route to network 172.16.0.0 will be 90.
The metric for routes to 172.16.0.0 will be 1.
The interface that is used to forward packets to 172.16.0.0 will always be the S0/1 interface.

18. The following line of code is present in the routing table:
O 10.16.1.0/27 [110/129] via 192.168.1.5, 00:00:05, Serial0/0/1
What does the number 129 indicate in this output?
The cost for this link has a value of 129.
The clock rate on this serial interface is set to 129,000.
The next-hop router is 129 hops away from this router.
This route has been updated 129 times in this routing table.

19. A growing medium-sized manufacturing company recently began to have routing instability issues. The company uses static routes and has a mixture of over 30 Cisco and non-Cisco routers. The network administrator has decided to convert the network to dynamic routing. What characteristics of protocols should be considered in this selection process?
Distance vector routing protocols, such as RIP, converge more quickly than do link-staterouting protocols.
EIGRP can be used on all of the routers in the company.
OSPF can be used between the routers.
An exterior routing protocol, such as BGP, is recommended for growing companies.

20.

Refer to the exhibit. If RIP is the routing protocol, what is the value of themetric from router A to network 192.168.5.0/24?
3
4
56
624
724

21. A router learns two paths with equal metrics to a destination network via the RIP routing protocol. How will the router handle packets to the destination network?
The router will install the first route it learned into the routing table.
The router will install both routes in the routing table and load balance between the two.
The router will put the first route in the routing table, and denote the second route as a backup route.
The router will pick the path with the higher bandwidth and will place it in the routing table.

22. When multiple routing protocols have a route to the same destination network, what determines which route is installed in the routing table?
best metric
lowest hop count
greatest available bandwidth
lowest administrative distance
lowest cost
