CCNA Exploration 4.0: Routing Protocols and Concepts – Chapter 3 Exam Answers

1. Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

* Administrative distance refers to the trustworthiness of a particular route.
A router first installs routes with higher administrative distances.
The value of the administrative distance can not be altered by the network administrator.
* Routes with the smallest metric to a destination indicate the best path.
The metric is always determined based on hop count.
The metric varies depending which Layer 3 protocol is being routed, such as IP or IPX.

2.

Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?

R1 will install a RIP route using network A in its routing table because the administrative distance of RIP is higher than EIGRP.
R1 will install a RIP route using network A in its routing table because the path cost from RIP is lower than EIGRP.
* R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP.
R1 will install an EIGRP route using network B in its routing table because the path cost from EIGRP is lower than RIP.
R1 will install an EIGRP route and a RIP route in its routing table and load balance between them.

3. Which two statements are true regarding classless routing protocols? (Choose two.)

* sends subnet mask information in routing updates
sends complete routing table update to all neighbors
is supported by RIP version 1
* allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
reduces the amount of address space available in an organization

4. Which command would the network administrator issue to determine if load balancing is in effect on a router?

show ip protocols
* show ip route
show ip interface brief
show ip interface
