SOA Certified Professional Cloud Technology Lab 認定 C90-03A 試験問題:

1. Cloud Provider X (which owns Cloud X) deploys two physical servers (Physical Servers A and B) and two databases (Databases A and B). Virtual Servers A and B are hosted by Physical Server A and Ready-Made Environments A and B are hosted by Virtual Server B. Virtual Servers C and D are hosted by Physical Server B. Cloud Service Consumer A regularly accesses Virtual Server D in order to test and deploy a new cloud service that was developed on-premise by the cloud consumer organization operating Cloud Service Consumer A. Cloud Service Consumer B (operated by a different cloud consumer organization) has been regularly accessing Ready-Made Environment A in order to develop and deploy a different new cloud service.
The cloud consumer organizations that own and operate Cloud Service Consumers A and B will soon be ready to launch their respective cloud services for use by their customers. Both cloud consumer organizations are concerned that Cloud X does not provide sufficient security and they demand that Cloud Provider X take the necessary steps to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security threats.

Which of the following statements accurately describes the cloud delivery models used now by the cloud service consumers and in the future by their customers - and - further describes a solution
that fulfills the identified security requirements by implementing a single cloud security mechanism?

A) Cloud Provider X is providing a hybrid delivery model comprised of a combination of theIaaS and PaaS delivery models, which means that Cloud Service Consumers A and B are using both theIaaS and PaaS delivery models. Customers of the cloud services will be using the PaaS delivery model. The single sign-on mechanism can be implemented to mitigate the denial of service and insufficient authorization security threats. The encryption mechanisms can be implemented to mitigate the overlapping trust boundaries security challenges.
B) Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the PaaS delivery model. Customers of the cloud services will be using the SaaS delivery model. The digital signatures mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security challenges.
C) Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the PaaS delivery model.Customers of the cloud services will be using the SaaS delivery model. An identity and access management mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security challenges.
D) Cloud Service Consumer A is using theIaaS delivery model. Cloud Service Consumer B is using the SaaS delivery model. Customers of the cloud services will be using the PaaS delivery model. The encryption mechanism can be implemented to mitigate the denial of service, insufficient authorization and overlapping trust boundaries security threats.

2. Cloud Provider Y owns Cloud Y, which provides a set of cloud services, virtual servers and one physical server. Cloud Services A and B are hosted on Virtual Server A, which is hosted by Physical Server A. Physical Server A also hosts Virtual Server B, which hosts redundant implementations of Cloud Services A and B for load balancing purposes. Cloud Service Consumer A is accessing Cloud Service A located on Virtual Server A. Cloud Service Consumer B is accessing Cloud Service B located on Virtual Server B. Cloud Service Consumers A and B are both owned by Cloud Consumer X.
Cloud Consumer X has recently complained that Cloud Services A and B have become less available than what is guaranteed in their service level agreements (SLAs). Cloud Provider Y launches an investigation that reveals that Virtual Servers A and B have been subjected to denial of service attacks. This is confirmed as the cause of the decline in the availability of Cloud Services A and B.

Which of the following statements describes a solution that can increase the availability of Cloud Services A and B?

A) Cloud Provider Y can implement a cloud bursting system, whereby Cloud Service A on Virtual Server B automatically takes the place of Cloud Service A on Virtual Server A when that service fails. Similarly,Cloud Service B on Virtual Server A can then automatically take the place of Cloud Service B on Virtual Server A when that service fails.
B) Cloud Provider Y can move Cloud Service B to Virtual Server A, thereby positioning Virtual Server B as a redundant fallback server used when Virtual Server A is successfully attacked. Similarly, Cloud Provider Yean move Cloud Service A to Virtual Server B, so that Virtual Server A acts as a redundant fallback server for when Virtual Server B is successfully attacked.
C) Cloud Provider Y can introduce a single sign-on mechanism for Virtual Server A to mitigate denial of service threats. The automated scaling listener can then be implemented on VirtualServer B in order to limit the number of instances of Cloud Services A and B. This will prevent Virtual Server B from overloading due to denial of service attacks.
D) Cloud Provider Y can implement the identity and access management mechanism to mitigate denial of service attacks and can further implement the failover system mechanism (by introducing a redundant physical server with redundant virtual servers) so that when an attack is successful on a given virtual server, a redundant virtual server can take its place.
