In order to provide high availability and ensure that Consul’s state is preserved even if a server fails, HashiCorp suggests that Consul should be configured to run __________.
A . on a public cloud platform that can provide hardware redundancy
B. only Kubernetes to provide scheduling for new Consul nodes
C. on as many servers as needed to scale for performance
D. in a cluster made up of three to five servers

Answer: D

Explanation:

In order to make sure that Consul’s state is preserved even if a server fails, you should always run either three or five servers in production. The odd number of servers (and no more than five of them) strikes a balance between performance and failure tolerance. When scaled beyond (7) servers, the network requirements needed to maintain replication between the clusters may negatively impact the performance of Consul.

Additionally, Consul is a platform and cloud-agnostic solution, meaning that it doesn’t have to be run on specific technology for customers to reap the benefits of using Consul.
