Question

The cloud service owner of Cloud Service A is evaluating Clouds X, Y and Z to determine which cloud environment can offer the greatest level of reliability. All three clouds are geographically dispersed across three separate time zones. As a result, each cloud experiences usage peaks at different times. Based on the metrics provided, the greater the usage of a cloud, the lower its reliability. When the cloud service owner complains to Cloud Provider A (the owner of all three clouds) that none of the clouds provide an adequate level of reliability, Cloud Provider A suggests a solution that increases resiliency.

Which of the following statements accurately describe how a cloud balancing solution can be implemented to fulfill the resiliency requirements of Cloud Service A?

Dorothy · Accepted Answer

A) Cloud Service A is redundantly deployed in advance within Clouds X. Y and Z and is further supplemented with failover system mechanisms and specialized types of automated scaling listener mechanisms. and D) Clouds X, Y and Z are equipped with failover system mechanisms and specialized types of automated scaling listener mechanisms in order to establish cross-cloud resiliency. Cloud Service A is configured so that Clouds X, Y and Z can dynamically generate redundant instances on-demand.

Dorothy · Answer

B) Using a PaaS environment, the cloud service owner can configure a primary Cloud Service A implementation on Cloud X so that when failure conditions occur, message requests from cloud service consumers are automatically routed to a redundant on-premise implementation of Cloud Service A . This requires the implementation of the failover system and resource replication mechanisms.

Dorothy · Answer

C) A type of automated scaling listener that can also be considered a cloud monitor is implemented in Clouds X, Y and Z to establish a system whereby each cloud can assume control of cloud service consumer message exchanges. This results in resilient cloud balancing, as opposed to on-demand cloud balancing.
