質問 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 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.

（B）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.

（C）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.

（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.

質問 2

Cloud X is a private cloud that, to-date, has been set up within the cloud provider company
to provision IT resources free of charge to internal cloud consumers, via PaaS and IaaS
delivery models. The cloud consumers that have been operating Cloud Service Consumers
A and B represent different IT departments within the company that have been working
separately on the development of new cloud services. Cloud Service Consumer A has
been accessing Virtual Server D to make necessary configurations and administration
settings for the upcoming deployment of a new cloud service that was previously
developed outside of Cloud X.
Cloud Service Consumer B has been accessing Ready-
Made Environment A to develop and now deploy a different new cloud service.
Cloud Provider X (which is represented by a separate IT department dedicated to
governing and administering Cloud X) determines that it will need to introduce three
specific enhancements to Cloud X in order to accommodate both upcoming cloud services.
First, it needs to add a way to charge cloud consumers for the usage of cloud services.
Secondly, it needs to add a way for new cloud services to be automatically scaled. Finally,
it needs to add a way for a cloud consumer to be automatically notified when a cloud
service encounters runtime loads that exceed its allocated usage threshold.
Which of the following statements accurately describes a solution that fulfills all three
identified requirements?

（A）The state management database mechanism together with the virtual server mechanism
and the automated scaling listener mechanism can be implemented to address the
requirement for cloud service usage charges to be tracked and recorded, for cloud services
to be automatically scaled, and for notifications to be issued when cloud service loads
exceed thresholds.

（B）The pay-for-use monitor mechanism can be implemented to address the requirement for
cloud service usage charges to be tracked and recorded, for cloud services to be
automatically scaled, and for notifications to be issued when cloud service loads exceed
thresholds.

（C）The pay-for-use monitor mechanism can be installed to address the requirement for
cloud service usage to be tracked and recorded. The automated scaling listener
mechanism can be implemented to address both the requirement for cloud services to be
automatically scaled and for notifications to be issued when cloud service loads exceed
thresholds.

（D）The pay-for-use monitor mechanism can be installed to address the requirement for
cloud service usage charges to be tracked and recorded. The automated scaling listener
mechanism can be implemented to address the requirement for cloud services to be
automatically scaled. The multi-device broker mechanism can be implemented to address
the requirement for notifications to be issued when cloud service loads exceed thresholds.
