200-301 Question 6
Select 2You are tasked with configuring a new router in your network. The goal is to enable the router to forward packets between two different subnets. Which of the following are essential steps to achieve this functionality?
- A
Assign IP addresses to the router's interfaces corresponding to the subnets
- B
Configure a routing protocol like OSPF or EIGRP on the router
- C
Enable CDP (Cisco Discovery Protocol) on the router
- D
Ensure the interfaces connected to the subnets are in an 'up' state
- E
Set up NAT (Network Address Translation) on the router
Show answer and explanation
Correct answers: A, D
Explanation
To enable a router to forward packets between two different subnets, the fundamental requirements are assigning IP addresses to the router's interfaces and ensuring the interfaces are operational ('up'). Routing protocols, CDP, or NAT are not essential in this specific scenario, as the router can directly route traffic between connected subnets without additional configurations.
- A. Correct.
Assigning IP addresses to the router's interfaces is crucial for it to communicate with devices in the respective subnets. Without IP addresses, the router cannot forward packets.
- B. Incorrect.
Configuring a routing protocol is not strictly required for routing between directly connected subnets. Static routing or directly connected routes are sufficient in this scenario.
- C. Incorrect.
Enabling CDP is not related to the router's ability to forward packets. CDP is used for network discovery and troubleshooting.
- D. Correct.
Ensuring the interfaces are in an 'up' state is necessary for the router to forward packets. If the interfaces are down, no communication can occur.
- E. Incorrect.
Setting up NAT is not required for routing between subnets within the same private network. NAT is primarily used for translating private IP addresses to public IP addresses.
