Question No. 1

Correct Answer: D

Question No. 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?

AThe 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.

BThe 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.

CThe 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.

DThe 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 .

Correct Answer: D

Question No. 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 describe how a cloud balancing solution can be implemented to fulfill the resiliency requirements of Cloud Service A?

ACloud Service A is redundantly deployed in advance within Clouds X. Y and Z and is further supplemented with failover system mechanisms and specialized types of automated scaling listener mechanisms.

BUsing a PaaS environment, the cloud service owner can configure a primary Cloud Service A implementation on Cloud X so that when failure conditions occur, message requests from cloud service consumers are automatically routed to a redundant on-premise implementation of Cloud Service A . This requires the implementation of the failover system and resource replication mechanisms.

CA type of automated scaling listener that can also be considered a cloud monitor is implemented in Clouds X, Y and Z to establish a system whereby each cloud can assume control of cloud service consumer message exchanges. This results in resilient cloud balancing, as opposed to on-demand cloud balancing.

DClouds X, Y and Z are equipped with failover system mechanisms and specialized types of automated scaling listener mechanisms in order to establish cross-cloud resiliency. Cloud Service A is configured so that Clouds X, Y and Z can dynamically generate redundant instances on-demand.

Correct Answer: A, D

Question No. 4

Cloud Consumer A (the organization that owns Cloud Service Consumer A) needs regular access to an external, cloud-based Weather Service that provides up-to-date weather forecast information. Cloud Providers X, Y and Z are competing public cloud providers, each offering a Weather Service with the features required by Cloud Consumer A .

Based on the provided statistics, which cloud provider can offer a Weather Service with the least amount of projected downtime?

ACloud Provider X

BCloud Provider Y

CCloud Provider Z

DAny of the three cloud providers, because their availability ratings are identical.

Show Answer

Correct Answer: A

Question No. 5

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 Provider X needs to make Cloud Service A available to a new group of cloud service consumers, but must do so without the increase in usage volume affecting Cloud Service Consumers A and B .

Which of the following statements does not accurately describe a solution (or a set of solutions) that addresses this requirement?

ACloud Provider X can scale up Cloud Service A by upgrading the Physical Server A hardware to increase the server's processing power. Cloud Provider X can scale out Cloud Service A by adding redundant implementations of the service and by using the automated scaling listener mechanism.

BCloud Provider X can scale out Cloud Service A by implementing new cloud computing mechanisms, such as the virtual server and resource replication mechanisms, which can enhance the cloud's elasticity characteristic.

CCloud Provider X can upgrade its infrastructure by increasing its ability to horizontally scale IT resources that are used by Cloud Service A . Cloud Provider X can upgrade its infrastructure in order to vertically scale IT resources that are used by Cloud Service A .

DCloud Provider X can upgrade its infrastructure to increase the cloud's ubiquitous access characteristic. This will enable the cloud to provide distributed failover for IT resources across multiple devices in order to increase its ubiquitous resiliency. To achieve this, Cloud Provider X will further need to implement the failover system, state management database and resource replication mechanisms.
