The following questions are designed to test your understanding of this chapter's material. You can find the answers in Appendix A. For more information on how to obtain additional questions, please see this book's Introduction.

1  What cloud model gives you complete control of the operating system?IaaSPaaSSaaSCaaS

2 A cloud service provider allocates resources into a group. These resources are then dynamically allocated and reallocated as the demand requires. What is this referred to as?On-demand virtualizationDynamic scalingResource poolingElasticity

3 What are three examples of IaaS elements you can provision in the cloud? (Choose three.)CPUOS ACLsMemoryStorageScalabilitySSH

4 Which of the following is not a valid pooled resource?MemoryStorageSecurityNetworkingCPU

5 What technologies are used to enable on-demand computing? (Choose two.)Load balancingAutomationAutoscaling groupsVirtualization

6 When you migrate your operations to the cloud and you decide to match computing resources with your current requirements, what can you take advantage of to expand your compute capacity in the future? (Choose three.)ElasticityOn-demand computingAvailability zonesResiliency virtualizationPay as you growRegions

7 Your company has decided to use one cloud provider for a production application while using a different cloud provider for storing backups. What type of cloud delivery model is this?PublicHybridCommunityPrivate

8 In a traditional virtualized data center, what shared network resource do VMs on the same host use to communicate with each other?Virtual NICRegionVirtual switchLAN

9 Which cloud characteristic allows you to pay for only the services used?BurstingPay as you growChargebackAutoscaling

10 When migrating an application from the data center to the cloud, which of the following is a best practice?Deploy to a test environment to validate functionality and performance.Deploy directly to production so that end users can immediately report any problems.Clone the VM running the application and upload it to the cloud.Copy the application files to a fresh VM running in the cloud.
