What is EIGRP primarily used for?

1. To manage firewall settings

2. To detect and manage topology changes

3. To create a static routing table

4. To connect to cloud services

The correct answer is: To detect and manage topology changes

EIGRP, which stands for Enhanced Interior Gateway Routing Protocol, is a dynamic routing protocol employed to facilitate efficient routing within an autonomous system. It is particularly adept at adapting to changes in the network topology. When there are changes, such as the addition or removal of devices, EIGRP quickly recalculates the best paths for routing data, allowing for minimal disruption in communication. This adaptability is central to its design, making it ideal for environments where network configurations may frequently change. Dynamic routing protocols like EIGRP automatically detect topology changes and propagate this information throughout the network, ensuring that all routers have an updated view of the network’s layout. This capability enhances the robustness and reliability of routing decisions, optimizing traffic flows and improving overall network performance. In contrast, managing firewall settings, creating static routing tables, or connecting to cloud services do not encompass the primary functions of EIGRP. Static routing would involve manual configurations of routes, which EIGRP inherently seeks to automate. Similarly, while EIGRP can play a role in routing to services that may reside in a cloud infrastructure, it is fundamentally a protocol designed to manage and adapt routing paths across a network based on its current topology, rather than directly interfacing with cloud services or managing security configurations
