Pregunta 36. What is the difference between static routing and dynamic routing?
Static routing requires manual configuration of routes, while dynamic routing protocols automatically adapt to changes in the network topology.
Pregunta 37. What is the purpose of the EIGRP (Enhanced Interior Gateway Routing Protocol)?
EIGRP is a Cisco proprietary routing protocol that uses a composite metric based on bandwidth, delay, reliability, and load to determine the best path.
Pregunta 38. Explain the concept of NAT overload (PAT - Port Address Translation).
NAT overload allows multiple private IP addresses to be mapped to a single public IP address by using different port numbers.
Pregunta 39. What is the purpose of the HSRP (Hot Standby Router Protocol)?
HSRP provides high availability by allowing multiple routers to work together in a group, with one router acting as the active router and the others as standby routers.
