A network administrator is setting up two new firewalls for redundancy and needs to implement a redundant internet connection. Which of the following routing technologies will the administrator most likely use?

Rationale

BGP

Border Gateway Protocol (BGP) is the most suitable choice for implementing a redundant internet connection because it is specifically designed for routing between different autonomous systems on the internet, allowing for multiple paths and redundancy in connections to different ISPs.

A (EIGRP) YOUR ANSWER

Enhanced Interior Gateway Routing Protocol (EIGRP) is primarily used for routing within a single autonomous system. While it supports redundancy, it is not designed for inter-domain routing, making it less effective for managing multiple internet connections across different ISPs.

B (RIPv2) YOUR ANSWER

Routing Information Protocol version 2 (RIPv2) is a distance-vector routing protocol that is limited in scalability and flexibility. It is typically used in smaller networks and does not offer the advanced features necessary for managing redundancy in internet connections across multiple ISPs.

C (OSPF) YOUR ANSWER

Open Shortest Path First (OSPF) is an interior gateway protocol suited for routing within a single autonomous system. Although it supports redundancy and load balancing, it is not optimized for inter-domain routing like BGP, which is needed when connecting to multiple external networks.

D (BGP) CORRECT

BGP effectively manages routing between different autonomous systems and provides robust mechanisms for failover and redundancy. It allows network administrators to set policies for path selection and can handle multiple connections from different ISPs, making it the optimal choice for a redundant internet connection.

Conclusion

In scenarios requiring redundant internet connections, BGP stands out as the most appropriate routing technology due to its design for inter-domain routing and ability to facilitate multiple paths between autonomous systems. While EIGRP, RIPv2, and OSPF serve important roles in internal routing, they lack the capabilities necessary for managing diverse and redundant connections across the internet. This makes BGP indispensable in ensuring reliable and resilient network connectivity.
