Which configuration will allow the hosts on the Branch LAN to access resources on the HQ LAN with the least impact on router processing and WAN bandwidth?
A. 
HQ(config)# ip route 192.168.1.0 255.255.255.0 192.168.2.5
Branch(config) # ip route 172.16.25.0 255.255.255.0 192.168.2.6
B. 
HQ(config)# router rip
HQ(config-router)# network 192.168.2.0 
HQ(config-router)# network 172.16.0.0 
Branch(config)# router rip 
Branch(config-router) # network 192.168.1.0 
Branch(config-router)# network 192.168.2.0
C. 
HQ(config)# router eigrp 56
HQ(config-router)# network 192.168.2.4 
HQ(config-router)# network 172.16.25.0 
Branch(config)# router eigrp 56 
Branch(config-router)# network 192.168.1.0 
Branch(config-router) # network 192.168.2.4
D. 
HQ(config)# router ospf 1
HQ(config-router)# network 192.168.2.4 0.0.0.3 area 0 
HQ(config-router)# network 172.16.25.0 0.0.0.255 area 0
Branch(config)# router ospf 1
Branch(config-router)# network 192.168.1.0 0.0.0.255 area 0
Answer: A
Explanation
By configuring static route, we can minimize the router processing and WAN bandwidth.
