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 to 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 (20 + 30 + 50) hours = 100 hours.
The actual usage is (20 + 30 + 50) X 5 server hours = 500 server hours.
The cost of using virtual servers from Cloud Provider X is (500 X 5 X$10) = $25,000.
The cost of using virtual servers from Cloud Provider Y is (500 X $20) = $10,600.
The cloud consumer must therefore choose Cloud Provider Y.
B. The total usage duration is (20 + 30 + 50) hours = 100 hours.
The actual usage is (20X3)+ (30X4) + (50X5) hours =430 hours.
The cost of using virtual servers from Cloud Provider Xis100X5X$10 = $5,000.
The cost of using virtual servers from Cloud Provider Y is 430 X $20 = $8,600.
The cloud consumer must therefore choose Cloud Provider X.
C. The total usage duration is (3 x 20) + (4 x 30) + (5 x 50) hours = 430 hours.
The actual usage is (20 + 30 + 50) hours = 100 hours.
The cost of using virtual servers from Cloud Provider X is (430 X $10) = $4,300.
The cost of using virtual servers from Cloud Provider Y is (100 X $20) = $2,000.
The cloud consumer must therefore choose Cloud Provider Y.
D. The total usage duration is (20 + 30 + 50) x 12 hours = 1,200 hours.
The actual usage is (20 X 3) + (30 X4) + (50 X 5) server hours = 430 server hours.
The cost of using virtual servers from Cloud ProviderXis12X5X$10 = $600.
The cost of using virtual servers from Cloud Provider Y is 430 X $20 = $8,600.
The cloud consumer must therefore choose Cloud Provider X.

문제 #2

Cloud X (owned by Cloud Provider X) provides Physical Server A which hosts Virtual
Servers A and B.
Virtual Server B hosts Ready-Made Environments A and B.
Cloud Service Consumer A uses Virtual Server A as part of an IaaS leasing agreement in which
Cloud Consumer A is charged a fixed monthly fee for unlimited access. Cloud Service
Consumers B and C use Ready-Made Environments A and B respectively as part of a
PaaS leasing agreement based on per-minute usage fees. In both cases, access is
monitored via Pay-For-Use Monitor A, which keeps track of log-in and log-out times in
order to calculate the usage charges that are billed to Cloud Consumers B and C.
Virtual Server A begins generating a series of exceptions. Soon thereafter, Virtual Server B
becomes destabilized, resulting in further exceptions being raised in Ready-Made
Environments A and B.
Cloud Service Consumers B and C receive a series of error
messages until both of their connections are dropped Finally, Physical Server A shuts
down completely. A subsequent investigation reveals that Virtual Server A was the victim of
a security attack performed by a malicious cloud service consumer, the attacker generated
increased loads of external communication requests on Virtual Server A and the underlying
network, causing Physical Server A (along with Virtual Server B) to eventually shut down.

Which of the following statements accurately identifies the type of security threat that
corresponds to the described attack - and -provides a solution that can directly mitigate this
type of security threat within Cloud X?

A. Virtual Server A was subjected to an insufficient authorization attack that can be
mitigated by implementing the digital signature and hardened virtual server image
mechanisms.
B. Virtual Server A was subjected to a denial of service attack that can be mitigated by
implementing the hardened virtual server image and identity and access management
mechanisms.
C. Virtual Server A was subjected to an insufficient authorization attack that can be
mitigated by implementing the single sign-on mechanism.
D. Virtual Server A was subjected to a denial of service attack that can be mitigated by
implementing the encryption and digital signature mechanisms.

문제 #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 cloud-based security group mechanism that
establishes a logical trust boundary that encompasses Virtual Servers A and B.
B. 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.
C. 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.
D. Cloud Provider Y can implement the encryption and digital signatures mechanisms to
protect the contents of messages from being augmented by malicious service agents.
