Answer : D Explanation: Explanation: Because things fail, it is important for cloud architects to design with the assumption that the underlying microservices infrastructure can and will fail. However, when appropriately designed, nothing will really fail. The goal is applications that continue to function―even if the underlying physical hardware fails or is removed or replaced. One way to accomplish this goal is to avoid “single points of failure.” For example, having a distributed architecture supporting multiple instances, allows the infrastructure to reorganize service workloads as required.
