Actual exam question from Cisco's 200-301

Question #: 399
Topic #: 1

Refer to the exhibit. C-router is to be used as a "router-on-a-stick" to route between the VLANs. All the interfaces have been properly configured and IP routing is operational. The hosts in the VLANs have been configured with the appropriate default gateway. What is true about this configuration?

A. These commands need to be added to the configuration: C-router(config)# router eigrp 123 C-router(config-router)# network 172.19.0.0
B. These commands need to be added to the configuration: C-router(config)# router ospf 1 C-router(config-router)# network 172.19.0.0 0.0.3.255 area 0
C. These commands need to be added to the configuration: C-router(config)# router rip C-router(config-router)# network 172.19.0.0
D. No further routing configuration is required.

Show Suggested Answer

Suggested Answer: D 🗳️
Since all the same router (C-router) is the default gateway for all three VLANs, all traffic destined to a different VLA will be sent to the C-router. The C-router will have knowledge of all three networks since they will appear as directly connected in the routing table. Since the C-router already knows how to get to all three networks, no routing protocols need to be configured.

D is correct. However... tricky question though. They list the routing protocols to throw you off. The question is actually testing your knowledge of VLAN routing.

Selected Answer: D

If you can remember that you don't need a "network address" when configuring a router on a stick; then you can get this question right. Example of router on the stick configuration for inter vlan routing: interface GigabitEthernet0/0 no shutdown interface GigabitEthernet0/0.10 encapsulation dot1Q 10 ip address 192.168.10.1 255.255.255.0 interface GigabitEthernet0/0.20 encapsulation dot1Q 20 ip address 192.168.20.1 255.255.255.0 Lastly, remember to configure both ends of the port between the router and the switch as trunk ports.

They are trying to trick you. No routing protocols are needed for router on a stick. Plus they already told you everything was properly configured and functioning.

D is right because it describes Router on a Stick so it's a VLAN topic

Technically, you have to configure a native subinterface or none of this will work but since that wasn't an option and we know that "all interfaces have been configured properly and all ip routing is operational," the answer is therefore D.
