SOA Cloud Technology Lab 認定 C90.03 試験問題：
問題 #1
Cloud Service A is being made available on public Cloud X by Cloud Provider X via the
SaaS delivery model. Cloud Service A is hosted by Physical Server A that also hosts cloud
services being used by different cloud service consumers (and owned by different cloud
service owners).
Cloud Provider X needs to make Cloud Service A available to a new group of cloud service
consumers, but must do so without the increase in usage volume affecting Cloud Service
Consumers A and B.
Which of the following statements does not accurately describe a solution (or a set of
solutions) that addresses this requirement?
A. Cloud Provider X can scale out Cloud Service A by implementing new cloud computing
mechanisms, such as the virtual server and resource replication mechanisms, which can
enhance the cloud's elasticity characteristic.
B. Cloud Provider X can scale up Cloud Service A by upgrading the Physical Server A
hardware to increase the server's processing power. Cloud Provider X can scale out Cloud
Service A by adding redundant implementations of the service and by using the automated
scaling listener mechanism.
C. Cloud Provider X can upgrade its infrastructure to increase the cloud's ubiquitous
access characteristic. This will enable the cloud to provide distributed failover for IT
resources across multiple devices in order to increase its ubiquitous resiliency. To achieve
this, Cloud Provider X will further need to implement the failover system, state
management database and resource replication mechanisms.
D. Cloud Provider X can upgrade its infrastructure by increasing its ability to horizontally
scale IT resources that are used by Cloud Service A.
Cloud Provider X can upgrade its infrastructure in order to vertically scale IT resources that are used by Cloud Service A.
問題 #2
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 Service Consumer A is using the IaaS 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.
B. Cloud Service Consumer A is using the IaaS 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.
C. Cloud Service Consumer A is using the IaaS 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.
D. Cloud Provider X is providing a hybrid delivery model comprised of a combination of the
IaaS and PaaS delivery models, which means that Cloud Service Consumers A and B are
using both the IaaS 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.
問題 #3
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 Service A is becoming increasingly
unreliable. Cloud Provider Y launches an investigation that reveals that Virtual Server A
has been crashing sporadically due to successful malicious intermediary attacks where
malicious service agents have been inserting harmful data into messages sent by Cloud
Service Consumer A to Cloud Service A.
Which of the following statements describes a solution that can mitigate the malicious
intermediary attacks that have been occurring on Virtual Server A - and - can further help
prevent the same types of attacks from occurring on Virtual Server B?
A. Cloud Provider Y can implement the failover system mechanism by requiring that
redundant copies of all service agents be deployed. This will reduce the chances of any
one service agent performing malicious actions at runtime.
B. Cloud Provider Y can implement the cloud-based security group mechanism that
establishes a logical trust boundary that encompasses Virtual Servers A and B.
C. Cloud Provider Y can implement the encryption and digital signatures mechanisms to
protect the contents of messages from being augmented by malicious service agents.
D. Cloud Provider Y can implement the identity and access management mechanism for
Virtual Servers A and B by physically deploying this mechanism on Physical Server A and
then further implementing the resource replication mechanism to propagate the identity and
access management system across Virtual Servers A and B.
