Question #11 (Topic: )

Cloud Service A requires access to Cloud Storage Device A and Cloud Storage Device B.

A. The Elastic Network Capacity pattern can be applied to implement a system that dynamically assigns network ports to Virtual Server A before its processing capacity thresholds are reached. The Redundant Physical Connection for Virtual Servers pattern can be applied to create an alternative path to LUN B in Cloud Storage Device B. The Resource Pooling pattern can be applied to synchronize Cloud Storage Device A with other cloud storage devices. B. The Resource Reservation pattern can be applied to dynamically provision resources to Virtual Server A whenever its processing thresholds are being reached. The Persistent Virtual Network Configuration pattern can be applied to establish a persistent hyperlink to LUN B over the virtual network that cannot be lost. The Elastic Resource Capacity pattern can be applied to prevent Cloud Storage Device A from encountering resource constraints. C. The Elastic Resource Capacity pattern can be applied to establish a system that can dynamically allocate resources to Virtual Server A. The Multipath Resource Access pattern can be applied to establish a multipathing system that can provide an alternative path to LUN B in Cloud Storage Device B. The Resource Reservation pattern can be applied to establish a system that enables Organization A to have exclusive access to pre-defined resources on Cloud Storage Device A for a given period of time. D. None of the above.

Answer: C

Question #12 (Topic: )

Physical Server A hosts Hypervisor A which hosts Virtual Server A, Virtual Server B and an
active cluster comprised of three virtual servers. Virtual Server A hosts Ready-Made

A. The Load Balanced Virtual Server Instances pattern can be applied in combination with the Elastic Network Capacity pattern in order to establish a system whereby Ready-Made Environment A can be smoothly transitioned between hypervisors in the same cluster, while its underlying virtual server maintains the network connection. B. The Hypervisor Clustering pattern was incorrectly applied and therefore needs to be re- applied correctly in order to establish a native system capable of instantly relocating virtual servers between hypervisors within the same cluster. The Direct I/O Access pattern can then also be applied so that the virtual servers retain their network configurations regardless of which hypervisor within the cluster they reside on. C. The Non-Disruptive Service Relocation pattern can be applied to place a secondary copy of Ready-Made Environment A on Hypervisor B. The Persistent Virtual Network Configuration pattern can be applied so that virtual servers retain network configurations when moving to other hypervisors. D. The Load Balanced Virtual Server Instances and Persistent Virtual Network Configuration patterns can be applied together to ensure that the virtual servers retain their network configurations when moving to another hypervisor. The Redundant Storage pattern can further be applied to move the ready-made environment to another hypervisor without service impact.

Answer: C

Question #13 (Topic: )

A cloud provider has two cloud environments (Cloud A and Cloud B) that are in different

A. The Zero Downtime pattern can be applied to establish a cross-cloud failover system for the two Cloud Service A implementations. The Cross-Storage Device Vertical Tiering pattern can be applied to vertically scale data in Cloud Storage Device A across multiple other cloud storage devices dynamically. The Centralized Remote Administration pattern can be applied to establish a logical network perimeter around Organization A's IT resources, thereby protecting them from other cloud consumer organiza B. The Dynamic Failure Detection and Recovery pattern can be applied so that if Cloud Service A in Cloud A fails, a watchdog system attempts to automatically recover Cloud Service A. Assuming Cloud Storage Device A has support for multiple disk types, the Intra- Storage Device Vertical Data Tiering pattern can be applied so that Cloud Storage Device A is equipped with dynamic vertical scaling. The Resource Management pattern can be applied to allow cloud consumer organizations to perform management C. The Load Balanced Virtual Server Instances pattern can be applied to balance the virtual servers hosting Cloud Service A implementations across the two cloud environments. The Storage Workload Management pattern can be applied to balance workloads across both Cloud Storage Device A implementations. The Resource Reservation pattern can be applied to establish a physical network boundary around Organization A's IT resources, thereby protecting them from other cloud consumer organizations. D. None of the above.

Answer: B

Question #14 (Topic: )

Cloud Service A accesses LUN Aon Cloud Storage Device A when it receives requests to

A. The Bare-Metal Provisioning pattern can be applied to remotely provision Physical Server C with the operating system required to deploy the legacy systems. The Automated Administration pattern can be applied to enable Organization A to create custom scripts that can carry out the deployment of the legacy system components via the use of an intelligent automation engine. To provide Organization X with the tools to monitor IT resource usage and collect usage data so that security breaches and othe B. The Bare-Metal Provisioning pattern can be applied to enable Organization A to provisioning Physical Server C with legacy systems after the operating system has been installed. The Synchronized Operating State pattern can be applied to consolidate Organization A's legacy systems via a centralized administration portal from which it can then automate their deployment. The Automated Administration pattern can be applied to establish a series of workflow scripts customized to monitor and log propri C. The Rapid Provisioning pattern can be applied to enable Physical Server C to be remotely provisioned with the operating system and legacy systems. The Centralized Remote Administration pattern can be applied to enable Organization A's employees to remotely manage and administer legacy system deployment. The Pay-as-You-Go pattern can be applied to establish the custom monitoring functionality required by Organization A's legacy systems. D. None of the above.

Answer: A

Question #15 (Topic: )

Cloud Service A and Cloud Service B perform different functions but both share access to
Cloud Storage Device A when fulfilling requests from cloud service consumers that require
data access. Cloud Services A and B are hosted by Virtual Server A, which is hosted by
Hypervisor A on Physical Server A.
Cloud Service Consumer A accesses Cloud Service A to issue a request for data (1).
Cloud Service A queries a database in Cloud Storage Device A to retrieve the data (2).
Upon receiving the requested data, Cloud Service Consumer A combines it with additional
data to form a new collection of data. Cloud Service Consumer A then accesses Cloud
Service B and provides it with the new data (3). Cloud Service B accesses a different
database in Cloud Storage Device A to store the new data (4). Cloud Consumer B
accesses the usage and administration portal to upload new data (5). The data is uploaded
to Cloud Storage Device B (6).

A. The Resource Pooling pattern can be applied to pool the IT resources used by Cloud Service A so that requests from Cloud Service Consumer A can utilize these resources during peak usage times. The Non-Disruptive Service Relocation pattern can be applied so that, in the event of failure, Cloud Storage Device B can be migrated at runtime to a cloud in another geographic region. The Elastic Disk Provisioning pattern can be applied so that Organization B is only charged for the amount of data storag B. The Service Load Balancing pattern can be applied to balance the workloads across multiple Cloud Service A implementations. The Synchronized Operating State pattern can be applied so that Virtual Server A is automatically synchronized to a secondary implementation of Physical Server A located in a different geographic region. The Usage Monitoring pattern can be applied so Cloud Consumer B's resource consumption is tracked and logged at runtime. C. The Service Load Balancing pattern can be applied to create redundant service implementations of Cloud Service A, so that a load-balancing system can distribute workloads across the service implementations dynamically. The Zero Downtime pattern can be applied to establish a secondary deployment of Physical Server A in a different data center located in a different geographic region. The Elastic Disk Provisioning pattern is applied together with the Pay-as-You-Go pattern to establish systems that D. None of the above.
