• A.False
• B.True

Which of the following statements about the system established by the application of the Storage Maintenance Window pattern are true? (Choose Two)

• A.The system dynamically recovers a cloud storage device from failure conditions encountered during the maintenance outage.
• B.The system ensures that cloud consumers do not experience service interruption during cloud storage maintenance outages.
• C.The system limits the number of data requests that can be received by a single cloud storage device during a maintenance outage.
• D.The system temporarily moves cloud consumer data at runtime.

Applying the _______________ pattern allows virtual servers to directly connect to the_____________.

• A.Synchronized Operating State, operating system APIs
• B.Persistent Virtual Network Configuration, physical network cards
• C.Direct LUN Access, hypervisors
• D.Direct I/O Access, physical I/O cards

The system that is established by the application of the Dynamic Failure Detection and Recovery pattern can address which of the following issues: (Choose Three)

• A.the manual process to solve cloud-based IT resource failure is too slow
• B.cloud-based IT resources encountering runtime failure conditions require intervention
• C.cloud-based bare-metal physical servers need to be provisioned with operating systems
• D.the manual recovery of IT resources leads to additional failures

The following statements describe how the automated scaling listener mechanism can be used as part of the system that is established by the application of the Elastic Resource Capacity pattern.
Which of these statements are false? (Choose Two)

• A.The automated scaling listener monitors message traffic between cloud service consumers and the cloud services being hosted by the virtual server to which the pattern has been applied.
• B.The automated scaling listener withdraws previously assigned CPUs when they are no longer needed and returns them to the shared resource pool.
• C.The automated scaling listener assigns additional CPUs to the virtual server, based on the workload processing requirements.
• D.The automated scaling listener notifies the intelligent automation engine to execute a script that instructs the hypervisor to allocate additional resources.
