Question 1

Cloud Service Consumer A accesses Cloud Service A (1) that resides in Cloud X. a private cloud owned by the same organization acting as Cloud Consumer A . Cloud Service A processes the message from Cloud Service Consumer A and then sends back a response with the requested data (2). Next, Cloud Service Consumer A sends a message containing some of this data to Cloud Service B (3), which resides in public Cloud Y that is owned by Cloud Provider Y. After processing the message. Cloud Service B sends back a response with additional data to Cloud Service Consumer A (4). Finally, Cloud Service Consumer A writes the data it collected from Cloud Services A and B to Database A (5). Recently, Cloud Service Consumer A has been required to access Cloud Services A and B at a significantly higher rate, sometimes over 1,000 times within a given workday. This increased usage has not affected Cloud Service B' s performance. Cloud Service A, however, has been generating runtime exceptions, and responses to Cloud Service Consumer A have become increasingly slow and unreliable. It is determined that this decline in performance is due to infrastructure limitations within private Cloud X' s environment. Instead of investing in new infrastructure for Cloud X, it is decided to explore the feasibility of moving Cloud Service A to Cloud Y instead.

Which of the following statements describe valid financial considerations that can be taken into account for assessing the feasibility of this move?

AMoving Cloud Service A to Cloud Y will result in the need for Cloud Service A to undergo integration testing to determine how well it can function within Cloud Y and what changes may need to be made to Cloud Service A in order for it to behave as expected. The integration testing and the subsequent changes required for Cloud Service A to function correctly within Cloud Y will incur integration costs that need to be budgeted for.

BBecause, in this scenario, the cost of capital is comprised of the up-front costs added to the on-going costs, the cost of capital required to move Cloud Service A to Cloud Y will be higher than upgrading Cloud X to accommodate Cloud Service A' s increased usage.

CIf the existing infrastructure that currently resides in private Cloud X was purchased specifically in support of Cloud Service A, then there may be a financial loss resulting from moving Cloud Service A out of Cloud X. This can be considered sunk costs that need to be evaluated.

DBy moving Cloud Service A to Cloud Y, there may be a decrease in operational governance control over the Cloud Service A implementation. This can increase locked-in costs because Cloud Consumer A may be forced to form dependencies upon proprietary tools used to configure and maintain the Cloud Service A implementation.

Correct answer: A, C, D

Question 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?

AA 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.

BThe 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.

CA 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 nonrelational 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 .

DNone of the above

Correct answer: C

Question 3

The cloud service owner of Cloud Service A is evaluating Clouds X, Y and Z to determine which cloud environment can offer the greatest level of reliability. All three clouds are geographically dispersed across three separate time zones. As a result, each cloud experiences usage peaks at different times. Based on the metrics provided, the greater the usage of a cloud, the lower its reliability. When the cloud service owner complains to Cloud Provider A (the owner of all three clouds) that none of the clouds provide an adequate level of reliability, Cloud Provider A suggests a solution that increases resiliency.

Which of the following statements accurately describes a solution that can be used to fulfill the resiliency requirements of Cloud Service A?

ARedundant implementations of Cloud Service A are deployed in all three clouds. The failover system mechanism and a special type of automated scaling listener mechanism are implemented to establish a system whereby one redundant Cloud Service A implementation will automatically take over from another.

BA cloud balancing solution is established, whereby an automated scaling listener mechanism is implemented on each cloud in such a way that every cloud can automatically scale out to another cloud. As a result, if reliability problems occur on any one cloud, the subsequent requests will be scaled out to another cloud in a manner that is transparent to cloud service consumers.

CA failover system mechanism is implemented on Cloud X, which acts as the primary point of contact for cloud service consumers. Upon failure conditions occurring, the Cloud Service A implementation on Cloud X automatically hands over control of current and future message requests from cloud service consumers to Cloud Y. Cloud Y retains control of cloud service consumer communication until the next failure condition occurs, at which point it hands over control to Cloud Z. Finally, if a failure condition occurs in Cloud Z. control is handed back to Cloud X.

DA cloud balancing solution is established, whereby a resource replication mechanism is implemented on each cloud. This allows Cloud Service A to be automatically replicated across cloud environments, thereby enabling each implementation of Cloud Service A to take the place of another, whenever failure conditions occur.

Correct answer: A

Question 4

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 Services A and B have become less available than what is guaranteed in their service level agreements (SLAs). Cloud Provider Y launches an investigation that reveals that Virtual Servers A and B have been subjected to denial of service attacks. This is confirmed as the cause of the decline in the availability of Cloud Services A and B.

Which of the following statements describes a solution that can increase the availability of Cloud Services A and B?

ACloud Provider Y can implement the identity and access management mechanism to mitigate denial of service attacks and can further implement the failover system mechanism (by introducing a redundant physical server with redundant virtual servers) so that when an attack is successful on a given virtual server, a redundant virtual server can take its place.

BCloud Provider Y can move Cloud Service B to Virtual Server A, thereby positioning Virtual Server B as a redundant fallback server used when Virtual Server A is successfully attacked. Similarly, Cloud Provider Yean move Cloud Service A to Virtual Server B, so that Virtual Server A acts as a redundant fallback server for when Virtual Server B is successfully attacked.

CCloud Provider Y can implement a cloud bursting system, whereby Cloud Service A on Virtual Server B automatically takes the place of Cloud Service A on Virtual Server A when that service fails. Similarly, Cloud Service B on Virtual Server A can then automatically take the place of Cloud Service B on Virtual Server A when that service fails.

DCloud Provider Y can introduce a single sign-on mechanism for Virtual Server A to mitigate denial of service threats. The automated scaling listener can then be implemented on Virtual Server B in order to limit the number of instances of Cloud Services A and B. This will prevent Virtual Server B from overloading due to denial of service attacks.

Correct answer: A

Question 5

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:

Number Of Virtual Servers

Usage

3

20 Hours

4

30 Hours

5

50 Hours

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?

AThe 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.

BThe 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.

CThe 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.

DThe 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.
