SOA Cloud Architecture Lab 認定 C90.06 試験問題：

問題 #1

Cloud Storage Device A contains LUN A and can be accessed by external cloud consumers via a proprietary user portal that is used primarily by cloud consumers to upload and manage data for backup purposes. Pay-Per-Use Monitor A tracks the amount of data being uploaded and forwards this information to a billing management system. Cloud Storage Device B is a secondary cloud storage device. Data from Cloud Storage Device A is replicated synchronously to Cloud Storage Device B using a storage replication program (not shown). Cloud Storage Device A is further administered by a cloud resource administrator that works for the cloud provider, who accesses the cloud storage device via an internal usage and administration portal.

Three different cloud consumers (Sarah. William, Matilda) access Cloud Storage Device A to upload data for backup purposes (1). These three cloud consumers belong to different departments within the same organization, and therefore all three share LUN A.
Pay-Per- Use Monitor A collects the storage space data and forwards it to the billing management system (2).
The cloud provider offers premium and discount storage plans. With the premium plan, the data stored on Cloud Storage Device A is also replicated to Cloud Storage Device B.
With the discount plan, the data stored on Cloud Storage Device A is not replicated. Both plans are based on fixed-disk storage allocation. The cost of the premium plan is $5 per week for every GB of storage space and the cost of the discount plan is $2 per week for every GB of storage space. The SLA from the cloud provider guarantees availability of 97% for access to Cloud Storage Device A.
The three cloud consumers use Cloud Storage Device A as follows:
* Sara signs up for the discount backup plan and is allocated 50 GBs of storage space. A week later, she uploads 10 GBs of backup data. A week after that, she uploads another 35 GBs. She later finds out that for those two weeks her organization was billed $200, which is more than she was expecting. After she complains to the cloud provider, she learns about how fixed-disk storage allocation is billed. She asks the cloud provider to change her account to a different storage plan where she is only billed for the actual amount of storage space she uses at any given time. The cloud provider assures her that a new system will be set up to accommodate this request.
* William is on the premium backup plan. He uploads 1 to 3 GBs of important business data every day. After two weeks of daily uploads, he realizes that the centralized nature of the backup data on the cloud makes it more convenient for reporting purposes than the distributed nature of the same data in his on-premise environment. He uses an analysis tool to run queries against the cloud-based data. However, due to the large quantity of redundant data, the queries end up being ineffective and take too long to run. He asks the cloud provider to find a solution that can streamline the cloud-based data by reducing redundancy. By reducing the overall quantity of the data, the analysis queries will run faster.
* Matilda is on the discount backup plan and uploads backup data on a daily basis.
Over the course of two weeks she uploads over 200 GBs of data. She performs a daily backup at the end of each day by identifying the data to back up and then using the proprietary user portal to run the cloud backup procedure. This procedure can take 5 to 45 minutes, depending on the amount of data she is uploading. Matilda performs this as her last task of the day and therefore initiates the procedure before she leaves, but does not wait for it to complete. One day, she receives an e-mail from the cloud provider explaining that the backup procedure from the previous day had failed due to an unexpected hardware failure that occurred on Cloud Storage Device A.
The notification e-mail goes on to state that this type of failure falls within the 97% availability guarantee of her organization's SLA, and is therefore in compliance with the current provisioning agreement. Had a disaster occurred that night, the on-premise data could have been lost and Matilda would be held accountable. Matilda contacts the cloud provider to demand that the provisioning agreement be amended to upgrade their existing SLA to the maximum possible availability (which, for this cloud provider, is 99.999%). The cloud provider agrees to establish a system to accommodate this request.
Which of the following statements lists the patterns that can be applied to address the three issues raised by the three cloud consumers?

A. Storage Maintenance Window, Dynamic Failure Detection and Recovery, Broad Access
B. Storage Workload Management, Elastic Disk Provisioning, Centralized Remote Administration
C. Elastic Disk Provisioning, Dynamic Data Normalization, Zero Downtime
D. None of the above.

問題 #2

Physical Server A hosts Hypervisor A which hosts Virtual Server A, Virtual Server B and an active cluster comprised of three virtual servers. Virtual Server A hosts Ready-Made Environment A.
Ready-Made Environment A uses Cloud Storage Device A to store data related to the ready-made environment and its users. Cloud Service A is hosted by a high- availability (HA) virtual server cluster. Hypervisor A is a cluster-enabled hypervisor.

Developers access Ready-Made Environment A to work on the development of a new solution (1). During this usage. Ready-Made Environment A regularly reads and writes data to Cloud Storage Device A (2). Cloud Service Consumer B accesses Cloud Service A (3).
Cloud Service A queries data residing in Cloud Storage Device A in response to processing requests from Cloud Service Consumer B (4).
Hypervisor A is made part of a cluster of hypetvisors. Ready-Made Environment A, which is still hosted by Virtual Server Aon Hypervisor A, subsequently becomes unexpectedly unavailable. It then takes twenty minutes to pass before Virtual Server A and Ready-Made Environment A become available again on Hypervisor B (a hypervisor that is also part of the hypervisor cluster). This delay is considered unacceptable by Cloud Consumer A.
Furthermore, after being relocated to Hypervisor B, Virtual Server A is unable to connect to the network. By the time the cloud provider rectifies this second problem, Cloud Consumer A experiences a total of two hours of downtime.
Which of the following statements describes a solution that can minimize or entirely avoid a delay for the runtime relocation of Ready-Made Environment A?

A. The Load Balanced Virtual Server Instances pattern can be applied in combination with the Elastic Network Capacity pattern in order to establish a system whereby Ready-Made Environment A can be smoothly transitioned between hypervisors in the same cluster, while its underlying virtual server maintains the network connection.
B. The Non-Disruptive Service Relocation pattern can be applied to place a secondary copy of Ready-Made Environment A on Hypervisor B.
The Persistent Virtual Network Configuration pattern can be applied so that virtual servers retain network configurations when moving to other hypervisors.
C. The Load Balanced Virtual Server Instances and Persistent Virtual Network Configuration patterns can be applied together to ensure that the virtual servers retain their network configurations when moving to another hypervisor. The Redundant Storage pattern can further be applied to move the ready-made environment to another hypervisor without service impact.
D. The Hypervisor Clustering pattern was incorrectly applied and therefore needs to be re- applied correctly in order to establish a native system capable of instantly relocating virtual servers between hypervisors within the same cluster. The Direct I/O Access pattern can then also be applied so that the virtual servers retain their network configurations regardless of which hypervisor within the cluster they reside on.
