Explanation
The problem occurs most frequently when attempting to run OSPF between a Cisco router and 
another vendor’s router. The problem occurs when the maximum transmission unit (MTU) 
settings for neighboring router interfaces don’t match.

Question 22
Refer to the exhibit. 
CPE#show ip route 
192.168.1.0/24 is variably subnetted, 3 subnets, 3 masks 
B 192.168.1.0/24 [20/1] via 192.168.12.2, 00:00:06 
R 192.168.1.128/25 [120/5] via 192.168.13.3, 00:02:22, Ethernet0/1 
O 192.168.1.192/26 [110/11] via 192.168.14.4, 00:02:22, Ethernet0/2 
D 192.168.1.224/27 [90/1024640] via 192.168.15.5, 00:01:33, Ethernet0/3 
All traffic enters the CPE router from interface Serial0/3 with an IP address of 192.168.50.1. 
Web traffic from the WAN is destined for a LAN network where servers are load-balanced. An 
IP packet with a destination address of the HTTP virtual IP of 192.168.1.250 must be forwarded. 
Which routing table entry does the router use? 
A. 192.168.1.0/24 via 192.168.12.2 
B. 192.168.1.128/25 via 192.168.13.3 
C. 192.168.1.192/26 via 192.168.14.4 
D. 192.168.1.224/27 via 192.168.15.5
