How many types of routes can a Cisco router support?

A Cisco router supports three main types of routes: directly connected, static, and dynamic routes.

Directly connected routes are those routes that are associated with interfaces that are up and operational. This means that if a router has an interface configured with an IP address and that interface is operational, then routes that correspond to that interface will be directly connected. These routes are automatically added by the operating system when an interface is enabled with a valid IP address.

Static routes are routes that are manually configured by the network administrator. They provide a fixed path for data to follow, ensuring that packets are directed through a specific next hop or exit interface. Static routes are useful for scenarios where predictable routing is needed, or in smaller, simpler networks.

Dynamic routes are learned and maintained through routing protocols like RIP, OSPF, or EIGRP. These protocols enable routers to share information about network paths and automatically update the routing table with the best available routes based on real-time network changes.

The options mentioning only static and dynamic routes, or only directly connected routes, do not account for all types of routing that a Cisco router can support, while the choice that lists four types inaccurately includes "default routes" without categorizing them properly in the context of primary route
