Effective CISSP Questions

You are implementing a company network for a startup. The IP address of the intranet is 192.168.1.0/24. You split the intranet into two subnets connected by a router: 192.168.1.0/25 and 192.168.128.0/25. Which of the following is the best for the router to forward IP packets from one subnet to the other?
A. Relay agent
B. Routing protocols
C. Routed protocols
D. Static routes


Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is D. Static routes.

Static routes can be directly connected or manually configured routes, while dynamic routes are learned by routers through routing protocols.

A router forwards packets by referencing the routes in the routing table. A route can be added to the routing table by the router automatically or by the administrator manually, or learned from other routers through routing protocols.

Routing protocols support routers to talk to each other to share routes and routing information. In this question, there is no need for a router connecting two subnets to implementing routing protocols to share routes. A router typically will create the route for its interfaces automatically.

Routed protocols refer to the protocol that defines the PDU forwarded by a router while routing protocols are used to exchange routes between routers.
