Prepare Arcitura Education C90.03 Exam Questions

Question No 1:
Cloud Service Consumer A invokes Cloud Service A from Cloud X (owned by Cloud Provider X) (1). To fulfill the request from Cloud Service Consumer A, Cloud Service A needs to invoke Cloud Service B that resides on Cloud Y (owned by Cloud Provider Y) (2). After completing its processing, Cloud Service B sends a response to Cloud Service A (3). Cloud Service A verifies the response and then finally sends its response to Cloud Service Consumer A (4). The guaranteed availability of the Cloud Service A implementation is 95% and the guaranteed availability of the Cloud Service B implementation is 95%. Which of the following statements accurately describes the actual availability that Cloud Service Consumer A can receive based on the described scenario?

A. Because Cloud Service Consumer A's response message is processed by two separate cloud services, the combined availability increases as follows: 1 - (1 - 0.95) X (1 - 0.95) = 0.9975 or 99.75%
B. Because Cloud Service A acts as both a cloud service and cloud service consumer in order to process Cloud Service Consumer B's request message, Cloud Service A forms a dependency on Cloud Service
C. As a result, the combined availability decreases, as follows: 0.95 X 0.95 = 0.9025 or 90.25%
D. Cloud Service Consumer A benefits from redundant cloud service implementations, thereby increasing the guaranteed availability as follows: 1 - (1 - (0.95 - 0.1)) X (1 - (0.95 - 0.1)) = 0.9775 or 97.75%
E. As a result of the dependency formed by Cloud Service Aon Cloud Service B, the combined availability decreases significantly as follows: (0.95 X 0.95) - 0.1 = 0.8025 or 80.25%
