문제 #1

A cloud consumer is interested in leasing cloud-based virtual servers. It compares the
virtual servers offered by Cloud Provider X and Cloud Provider Y.
Cloud X (owned by Cloud Provider X) and Cloud Y (owned by Cloud Provider Y) both provide shared physical
servers that host multiple virtual servers for other cloud consumers.
The virtual servers on Cloud X are accessed directly, whereas the virtual servers on Cloud
Y are accessed via an automated scaling listener. On Cloud X, virtual servers are pre-
configured to support a specific amount of concurrent cloud service consumers. When this
threshold is exceeded, cloud service consumer requests are rejected. Due to the use of the
automated scaling listener, virtual servers on Cloud Y can provide a greater level of
elasticity.
The hourly cost to the cloud consumer to use a virtual server on Cloud X is half that of the
cost to use a virtual server on Cloud Y.
Within a one month period, Cloud Provider X bases its hourly charge on the maximum number of virtual servers used. Within a one month
period, Cloud Provider Y bases its hourly charges on actual virtual server usage. Cloud
Provider Y charges $20 for each hour that a cloud consumer uses a virtual server.

The cloud consumer predicts its monthly usage requirements to be as follows:

The cloud consumer is required choose the cloud provider with the lowest on-going cost
based on its predicted usage. Which of the following statements accurately calculates the
on-going usage costs of Cloud Providers X and Y and correctly states the cloud provider
that the cloud consumer must choose?

A. The total usage duration is (10 + 20 + 70) x 12 hours = 1.200 hours.
The actual usage is (10X6) + (20X4) + (70X2) hours = 280 server hours.
The cost of using virtual servers from Cloud Provider Xis12X100X5X$10 = $60,000.
The cost of using virtual servers from Cloud Provider Y is 280 X $20 = $5,600.
The cloud consumer must therefore choose Cloud Provider Y.
B. The total usage duration is (10 + 20 + 70) hours = 100 hours.
The actual usage is ((10 X 6) + (20 X 4) + (70 X 2)) x ((2 + 4 + 6) / 3) hours = 1,120 hours
The cost of using virtual servers from Cloud Provider Xis10QX6X$10 = $6,000.
The cost of using virtual servers from Cloud Provider Y is 1,120 X $20 = $22,400.
The cloud consumer must therefore choose Cloud Provider X.
C. The total usage duration is (10 + 20 + 70) hours = 100 hours.
The actual usage is ((10 X 6) + (20 X 4) + (70 X 2)) x ((2 + 4 + 6) / 3) hours = 1,120 hours
The cost of using virtual servers from Cloud Provider X is 6 X 100 X $10 = $6,000.
The cost of using virtual servers from Cloud Provider Y is 1,120 X $20 = $22,400.
The cloud consumer must therefore choose Cloud Provider Y.
D. The total usage duration is (10 + 20 + 70) hours = 100 hours.
The actual usage is (10 X 6) + (20 X 4) + (70 X 2) hours = 280 hours.
The cost of using virtual servers from Cloud Provider X is 100X6X$10 = $6,000.
The cost of using virtual servers from Cloud Provider Y is 280 X $20 = $5,600.
The cloud consumer must therefore choose Cloud Provider Y.

문제 #2

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 Service Consumers A and B access Cloud Service A on a regular basis and
Physical Server A has been able to accommodate the resulting usage load After reviewing
the implementation environment for Cloud Service A.
Cloud Provider X determines it needs to enhance the ubiquitous access and multi-tenancy characteristics within this part of Cloud
X.

Which of the following statements accurately describes a solution that fulfills all of these
requirements?

A. The multi-device broker mechanism can be implemented to address ubiquitous access
requirements by broadening the range of cloud service consumers that can access Cloud
Service A.
The resilient computing mechanism can be implemented to establish the
multitenancy capabilities of Cloud Service A so that it will be able to resiliency
accommodate the additional cloud service consumer devices that will gain access to it.
B. The resilient computing mechanism can be implemented to address ubiquitous access
requirements by making Cloud Service A available to a broader range of cloud service
consumer devices, including desktops running Web browsers and various mobile devices.
The resource replication mechanism can be implemented to enable multi-tenancy within
the Cloud Service A implementation.
C. The multi-device broker mechanism can be implemented to address ubiquitous access
requirements by broadening the range of cloud service consumers that can access Cloud
Service A.
The virtual server mechanism can be implemented to establish the multitenancy
capabilities of Cloud Service A.
D. The resource replication mechanism can be introduced to address ubiquitous access
requirements by broadening the range of cloud service consumers that can use Cloud
Service A via standard service replication. The virtual server mechanism can be
implemented to enable multi-tenancy via each service replication resulting from the
application of the resource replication mechanism.

문제 #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 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.
C. 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.
D. 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.
