MultipleChoice

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?

Options

AThe virtual server and resource replication mechanisms can be implemented to replicate Service A and Database A across both on-premise and cloud environments. This enables on-demand usage in that requests sent by Service Consumers A, B and C will automatically be redirected to the replicated service and/or database. As a result, Service A' s usage thresholds will no longer result in rejected requests and Database A' s processing limitations will no longer result in failed data access attempts.

BA cloud balancing solution can be implemented within the public cloud, whereby a redundant Cloud Service A implementation is established. Cloud Service A becomes the first point of contact for Service Consumers A, B and C (thereby turning them into Cloud Service Consumers A. B and C). Upon reaching its usage threshold (which will be higher than the on-premise Service A), Cloud Service A automatically routes usage requests to Service A . The resource replication mechanism is implemented within the cloud to establish a replicated Database A that can further be used to load balance data access requests from Cloud Service A or Service A .

CAutomated scaling listener mechanisms can be implemented in both the on-premise and cloud environments. Using built-in resiliency features, these service agents can be configured to coordinate the routing of messages between the on-premise Service A implementation and a redundant Cloud Service A implementation. This dynamic functionality can avoid service usage thresholds in both Service A and Cloud Service A .

DNone of the above.

Question No: 4

MultipleChoice

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?

Options

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.

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 option best statements provides a solution that uses cloud-based IT resources to solve the performance limitations of Service A and Database A?

Options

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 .

DThe virtual server and resource replication mechanisms can be implemented to replicate Service A and Database A across both on-premise and cloud environments. This enables on-demand usage in that requests sent by Service Consumers A, B and C will automatically be redirected to the replicated service and/or database. As a result, Service A' s usage thresholds will no longer result in rejected requests and Database A' s processing limitations will no longer result in failed data access attempts.

Question No: 6

MultipleChoice

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 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?

Options

AThe 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.

BThe 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.

CThe 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.

DThe 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.
