SOA Cloud Technology Lab 考試常見問題解答

最新的 SOA Certification C90.03 免費考試真題：

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 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.

問題 #2

Organization A has been expanding and, as a result, is outgrowing the processing capacity
of its on-premise Service A implementation. It is determined that this is due to usage
thresholds of Service A and complex data processing limitations in Database A.
The diagram depicts Organization A's current on-premise environment, where Service
Consumers A.
B and C attempt to access Service A at the same time. Service Consumer A
successfully accesses Service A, which then successfully retrieves the requested data (1).
Service Consumer B successfully accesses Service A, but due to the complex data
structure, the request for the data times out and fails (2). Finally, Service Consumer C
attempts to access Service A, but is rejected because Service A is unable to accept more
concurrent requests.

Organization A is required to continue using its on-premise Service A implementation, with
the exception of Database A, which does not need to remain on-premise. Database A is
dedicated to Service A and is comprised of relational data. Which of the following
statements provides a solution that uses cloud-based IT resources to solve the
performance limitations of Service A and Database A?

A. A cloud bursting solution can be implemented, whereby a redundant copy of Service A
is implemented within a public cloud. This cloud-based, redundant implementation of
Service A is referred to as Cloud Service A.
A copy of Database A is also implemented within the cloud and both the on-premise and cloud-based copies of Database A are
redesigned to be non-relational in order to improve data access performance. Service A
continues to act as a first point of contact for Service Consumers A, B and C.
An automated scaling listener is deployed so that when Service A's thresholds are met,
requests are automatically routed to Cloud Service A.
B. The state management database and resource replication mechanisms can be
implemented to establish redundant implementations of Service A and Database A in both
on-premise and cloud environments. Using resource replication, a cloud-based duplicate of
Service A (Cloud Service A) will be established in a public cloud and will remain in synch
with Service A via regular replication cycles. Using the resource replication mechanism
together with the state management database mechanism allows for Database A to be
dynamically replicated in an independent state management database that has redundant
implementations in both on-premise and cloud environments. The state management
database can be further optimized to support non-relational data to improve data access
performance.
C. None of the above
D. A failover system can be implemented in a hybrid architecture comprised of
Organization A's existing on-premise environment and a public cloud environment. The
failover system would span both environments so that when Service A is unable to process
request messages from Service Consumers A, B or C, the failover system can
automatically route messages to a redundant implementation of Service A residing in the
public cloud. Similarly, when Database A is unable to process a data access request from
Service A.the failover system can automatically route this request to a redundant
implementation of Database A, also residing in the public cloud.

問題 #3

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.

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 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.
B. 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.
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 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.
