Designing Cisco Data Center Infrastructure (DCID) — Question 115

After experiencing traffic disruptions from the failure of a single router, a customer asks an engineer to design a solution that will prevent this from occurring in the future. While examining the customer's environment, the engineer discovers that the routers are manufactured by a variety of different vendors, and they have varying amounts of CPU and memory resources. Additionally, several of the customer's applications require the ability to fine-tune the load-balancing parameters between multiple gateway routers.

Which solution should be used to meet these requirements?

Answer options

Correct answer: A

Explanation

The correct answer is VRRP (Virtual Router Redundancy Protocol) because it allows for the configuration of multiple routers to work together as a single virtual router, which is ideal for load balancing and redundancy in a mixed vendor environment. The other options, while also providing redundancy, do not offer the same level of flexibility in load-balancing parameter adjustments as VRRP does.
