Cisco CCNA mock exam questions sample test – Question 210

.Examine the output of the show ip route command below:
210
Which of the following statements is FALSE?

A. The route to 30.30.30.30 uses a cost of 21
B. The command ip route 192.168.2.0 255.255.255.0 172.16.14.2 200 will replace the current route to 192.168.2.0/24
C. The route to 192.168.2.0/24 uses the default administrative distance
D. Traffic will be load balanced across two routes to 30.30.30.30

Correct Answer: B

Explanation:
The command ip route 10.10.10.0 255.255.255.0 172.16.14.2 200 will NOT replace the current route to 10.0.0.0/24.
When you execute the ip route command to enter a static route, the administrative distance can be altered by adding the desired distance value to the end of the command. In this
scenario, the administrative distance value was set to 200. The route to the 10.10.10.0/24 network that is currently in the table was learned by OSPF and is using the default
administrative distance of 110. Since 110 is lower than 200, the new static route will not be added to the routing table UNLESS the current route becomes unavailable.
The route to 30.30.30.30 does uses a cost of 21, as is indicated by the value on the right side of the forward slash within the brackets found in the route entry, [50/21].
The route to 192.168.2.0/24 uses the default administrative distance. It was learned from OSPF, which has a default distance of 110. Its administrative distance is indicated by the
value on the left side of the forward slash within the brackets found in the route entry, [110/20].
Traffic will be load balanced across two routes to 30.30.30.30 because they have equal cost of 21. This cost is indicated by the value on the right side of the forward slash within the
brackets found in the route entry, [50/21].
