Cloud architectures

What is the primary goal of workload distribution architecture?

• To reduce IT resource over-utilization and under-utilization
  

• To increase IT resource efficiency
  

• To enable dynamic scaling of IT resources

• To optimize load balancing algorithms

Which IT resources can be horizontally scaled via workload distribution architecture?

• Distributed virtual servers

• Cloud storage devices

• Cloud services

• All of the above

What role does the balancer play in workload distribution architecture?

• It evenly distributes the workload among available IT resources

• It monitors the workload to fulfill legal and regulatory requirements

• It isolates cloud consumer network boundaries

• It generates new instances of virtualized IT resources

Which architecture is based on the use of resource pools to group identical IT resources?

• Workload distribution architecture

• Resource pooling architecture
  

• Dynamic scalability architecture
  

• Elastic resource capacity architecture

What is the purpose of resource pooling architecture?

• To maintain synchronization of identical IT resources

• To dynamically allocate IT resources based on demand fluctuations

• To scale cloud service implementations

• To enable dynamic provisioning of virtual servers

What are examples of resource pools?

• Physical server pools

• Virtual server pools

• Storage pools

• All of the above

What is the role of the logical network perimeter in resource pooling architecture?

• To isolate cloud consumer network boundaries
  

• To facilitate organization of resource pooling requirements

• To ensure compliance with privacy and regulation requirements

• To dynamically allocate CPUs and RAM to virtual servers

Which architecture is based on predefined scaling conditions that trigger dynamic allocation of IT resources?

• Workload distribution architecture

• Resource pooling architecture

• Dynamic scalability architecture

• Elastic disk provisioning architecture

What types of dynamic scaling are commonly used in dynamic scalability architecture?

• Horizontal scaling
  

• Vertical scaling

• Relocation

• All of the above

What is the purpose of the automated scaling listener in dynamic scalability architecture?

• To determine when new IT resources need to be added

• To provide logic for dynamically allocating IT resources

• To monitor and track runtime usage

• To allocate and reclaim CPUs and RAM based on processing requirements
