What type of routing is based on pre-defined paths in routers?

In static routing, each route is added by hand, meaning the router follows a pre-defined route to send data. It does not adjust automatically if there is a network failure, which makes it suitable for small or stable networks.

Key features of Static Routing:

• Routes are manually configured by a network administrator.


• Best for small or less complex networks.


• More secure and predictable, since routes do not change automatically.


• No extra CPU or memory usage on the router, unlike dynamic routing.

Other options:

• Dynamic Routing automatically updates routes based on network changes.


• Distance Vector Routing and Link State Routing are types of dynamic routing protocols.

Conclusion: The correct answer is Static Routing because it uses fixed, manually defined paths in routers. It is simple, fast, and secure for small networks without frequent changes.
