Online Access Free C90.06 Practice Test

Cloud Sen/ice A is hosted by Virtual Server A, which is hosted by Hypervisor A on Physical Server A.
Cloud Service B is hosted by Virtual Server B.
Virtual Server C hosts Cloud Services C and D.
Virtual Server B and Virtual Server C are hosted by Hypervisor B on Physical Server B.
Cloud Service Consumer A accesses Cloud Service A (1). Cloud Service Consumer B accesses Cloud Service A (2). Cloud Service Consumer C accesses Cloud Service A (3) and then accesses Cloud Service B (4).

Cloud Service Consumers A, B and C simultaneously access Cloud Service A.
Cloud Service Consumer C receives a runtime exception and its request for access is rejected. It is determined that Cloud Service Consumer C attempted to upload a large amount of input data for Cloud Service A, which exceeded the bandwidth threshold of the virtual network.
The cloud architecture needs to be improved to avoid this from happening again.
Cloud Service Consumer C's repeated access of Cloud Service B imposes workloads that are large and highly unpredictable. After some time, Cloud Service B begins to delay its responses and sometimes times out entirely. The cloud resource administrator discovers that Virtual Server B is unstable and close to failure primarily because its CPU and memory resources are being used to their maximum capacity.
Cloud Services C and D are being positioned as SaaS products for use by a range of cloud consumer organizations. After their initial release, they begin to quickly use up the available memory in Virtual Server C, primarily because of the large amounts of state and session data they need to place into memory for extended periods.
Which of the following statements lists the patterns that can be applied to solve these three requirements and problems?

• A.Elastic Network Capacity, Load Balanced Virtual Server Instances, Service State Management
• B.Persistent Virtual Network Configuration. Load Balanced Virtual Switches, Service State Management
• C.None of the above.
• D.Elastic Resource Capacity, Service Load Balancing, Synchronized Operating State

A cloud provider has two cloud environments (Cloud A and Cloud B) that are in different geographical regions. Cloud Service A resides in Cloud A.
A redundant implementation of Cloud Service A resides in Cloud B.
An automated scaling listener is used in Cloud A to automatically balance the workload of requests for Cloud Service A across the two redundant implementations. Cloud Service A is required to access Cloud Storage Device A, which also resides in Cloud A.
A redundant implementation of Cloud Storage Device A is located in Cloud B.
A failover system is used to ensure that if the Cloud Storage Device A implementation in Cloud A fails, the Cloud Storage Device A implementation in Cloud B takes its place.
Cloud Service Consumer A is owned by Organization A.
Cloud Service Consumer A sends a request to Cloud Service A (1). The automated scaling listener intercepts the request and directs it to the Cloud Service A implementation in Cloud A (2). This Cloud Service A implementation attempts to access Cloud Storage Device A in Cloud A, but Cloud Storage Device A fails (3). The failover system redirects the request to Cloud Storage Device A in Cloud B (4). Cloud Service Consumer B sends a request to Cloud Service A (5). The automated scaling listener intercepts the request and directs it to the Cloud Service A implementation in Cloud B (6). This Cloud Service A implementation accesses Cloud Storage Device A in Cloud B to fulfill the request (7).

An unexpected outage occurs in Cloud A, making Cloud Service A unavailable.
Organization A notices that its cloud resource administrator can continue accessing data in Cloud Storage Device A via a usage and administration portal. Cloud Service Consumer A is unable to access data in Cloud Storage Device A via Cloud Service A during the outage.
The cloud resource administrator manually restarts Cloud Service A and it continues to function normally.
Organization A needs to change the cloud architecture so that when Cloud Service A fails, three automated attempts are made to recover it before a manual restart is required.
Due to data storage regulations, Organization A is prohibited from storing some types of data across more than one cloud storage device. A large amount of the data in Cloud Storage Device A is subject to these regulations. Because of an increase in usage, the capacity of Cloud Storage Device A has reached its limit, resulting in regular delays and lag time when processing data access requests during peak usage times.
A management change by another cloud consumer organization inadvertently reconfigures settings in the failover system used in Cloud A for Cloud Storage Device A.
Organization A complains to the cloud provider who promises to take the steps required to prevent management tasks performed by other cloud consumer organizations from affecting IT resources being used by Organization A.
Which of the following statements describes a solution that can resolve all of these issues?

• A.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 tasks on IT resources without impacting IT resources being used by other cloud consumer organizations.
• B.None of the above.
• 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.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 organizations.
