Which of the following are reasons IT processes will change with cloud adoption? (Choose two.) A. Rapid elasticity B. More focus on software patching within an organization's IT department C. Less focus on software patching within an organization's IT department D. Less focus on cloud service performance

A and C. Rapid elasticity means it is easier for users to request new or additional IT services; Demand Management takes on new meaning with this. With SaaS, an organization's IT department is not responsible for patching software with updates; this is the cloud provider's responsibility. image B and D are incorrect. The cloud provider takes care of software patching for cloud services, not the organization's IT department. With cloud adoption, there is an emphasis on monitoring the performance of cloud services; this is something the cloud customer's IT staff can monitor.

For which businesses would cloud computing be best suited? (Choose two.) A. Waterfront marketplace that thrives during the summer tourist season B. Rural medical practice with four employees C. Law enforcement agency D. A new company start-up that manufactures watercraft

A and D. A waterfront marketplace that thrives seasonally means more computing resources are needed during certain times of the year; cloud computing provides elasticity, which means adding or removing computing services and user accounts as needed. New companies present a financial risk and may not have the desire to invest capital in computing resources on-site, so cloud computing offers an affordable solution without an expensive long-term commitment.

You are planning strategies related to your cloud provider becoming unavailable. Which of the following will ensure business continuity? (Choose two.) A. In-house hosting B. Cloud backup C. Network connectivity to the cloud provider D. Using an alternate cloud provider

A and D. Should a cloud provider become unavailable, hosting IT services in-house or with other cloud providers are possible contingency plans that will ensure business continuity. image B and C are incorrect. Cloud backup can ensure business continuity in the event of data loss but not if the cloud provider becomes unavailable. Network connectivity is always required to a cloud provider and is not relevant if the cloud provider is not reachable over the network.

Which of the following skills will internal IT require when adopting a cloud solution? A. Performance monitoring B. Security auditing C. Configuring network routers D. Writing scripts to automate virtual machine deployment

A. Adopting a cloud solution means monitoring the performance of the solution on an ongoing basis to ensure the solution presents business value. image B, C, and D. Security auditing is the cloud provider's concern, not the cloud consumer, as are configuring network routers and presenting the tools for virtual machine deployment.

Which of the following is not a consideration when planning IaaS adoption? A. Cloud provider application development tools B. Reduced time to deploy new servers C. OPEX versus CAPEX D. Ability to remove unneeded servers

A. Application development tools are related to PaaS, not IaaS.

True or false? Cloud computing is a form of outsourcing. A. True B. False

A. From a business perspective, cloud computing is a form of outsourcing.

Access Management is affected by which aspect of cloud computing? A. Identity federation B. Cloud backup C. Network connectivity to the cloud provider D. Virtualization

A. Identity federation allows a central identity store to be used both inside and outside of an organization. For example, Company A's user accounts can be used to gain access to resources in Company A and Company B, as well as Cloud Provider A. image B, C, and D are incorrect since they have nothing to do with Access Management. Cloud backup and dependencies on network connectivity are related to IT Service Continuity Management. Virtualization does affect all IT processes, but identity federation is a better answer.

How does cloud adoption change financial management skills? A. Yearly budget cycles change because of rapid cloud elasticity. B. Cloud customers must monitor their own cloud resource usage and pay accordingly. C. OPEX becomes CAPEX. D. Cloud service costs are fixed. E. Performance monitoring should be performed by the cloud customer's IT staff.

A. Instead of traditional yearly budget cycles, finance staff must account for the fact that rapid cloud elasticity will make OPEX variable. image B, C, D, and E are incorrect. Cloud providers monitor customer usage, and they bill the customers accordingly, not the other way around. Cloud adoption changes CAPEX to OPEX, not the other way around. Even though cloud customer IT staff should be monitoring cloud service performance, this is not related to financial management skills.

Which of the following are valid reasons for not adopting a cloud solution? (Choose two.) A. Local hardware is being fully utilized for unchanging IT workloads. B. The number of employees rarely changes. C. The number of employees changes often. D. A business experiences unpredictable project spikes throughout the year.

A. Local hardware is being fully utilized for unchanging IT workloads. B. The number of employees rarely changes.

A. Shared Hardware

How can unpredictable costs associated with cloud services be managed? (Choose two.) A. Choose the cheapest cloud provider. B. Set limits on total costs for a given timeframe. C. Ensure costs are related to revenue. D. Prohibit IaaS from being used.

B and C. Despite rapid elasticity, cloud costs can be managed by setting a limit on cloud-related costs and ensuring that these costs are relevant to the business. image A and D are incorrect. Choosing the cheapest cloud provider is not a good strategy; there are many variables to consider besides cost. Even though prohibiting the use of IaaS could reduce cloud costs, B and C are better answers.

When evaluating the migration of one of your applications to the cloud, you discover complexities that may make migration impossible. In this case, what strategy might you employ? A. Find a functionally equivalent cloud application. B. Migrate the application to the cloud anyway. C. Export application data, provision a new virtual machine in the cloud, and then import application data to the new virtual machine. D. Export application data, provision a new physical machine in the cloud, and then import application data to the new physical machine.

A. Sometimes specific commercial applications that run well within an organization are not available in the cloud. Often there are functionally equivalences offered by cloud providers; this should be researched by internal IT staff. image B, C, and D are incorrect because the question states that there are complexities impeding migration to the cloud.

What obstacle might an organization face related to Demand Management? A. Inability to provide enough computing infrastructure B. Lack of data security in public clouds C. Inability to rapidly deprovision compute resources D. Ability of users to access SaaS applications from anywhere

A. The ability of users to quickly provision computing services not only requires careful attention to computing infrastructure capacity and availability but also suggests capping how many services users can self-provision. image B, C, and D. Public cloud data security is considered superior to the data security provided by a single organization. The ability of users to rapidly deprovision computing services is seen as a benefit, not an obstacle. Accessing SaaS applications from anywhere is considered a benefit of cloud computing.

Service Transition relates to changes in IT service life cycles.

Which of the following risks must be assessed when considering cloud adoption? A. Weak security provided by public cloud providers B. Loss of network connectivity C. Failed virtual servers D. Lack of on-demand growth capacity

B. Without network connectivity to cloud services, virtual servers, data, and cloud applications are unavailable. This possibility must be assessed to determine whether the risk is acceptable. image A, C, and D. Public cloud providers have the requirement, resources, and expertise to exercise a higher degree of security than most organizations could do themselves. Failed virtual servers present a risk whether they are hosted by the organization or a cloud provider. High availability (clustering) and backups minimize downtime. On-demand provisioning of cloud services is one of the reasons organizations seek to adopt cloud solutions; it is not a risk.

True or false? Virtual servers are used only in public clouds. A. True B. False

B.False

You are negotiating SLA terms with your cloud provider. Your company's chief financial officer, Mia, has concerns with items contained within the SLA. Which item might Mia be interested in? A. Cloud service uptime B. Switching CAPEX to OPEX C. Cloud service termination fees D. Web page loading time

C. Cloud service termination fee terms can be buried in the SLA and must be accounted for as they relate to an exit strategy. image A, B, and D are incorrect. Cloud service uptime and web page loading time are technical details that would interest the IT department, not the finance people. Switching CAPEX to OPEX is not part of an SLA.

Which of the following items directly relate to Change Management? A. Negotiating SLA details B. Meeting demand for IT services C. Installing new software D. Ensuring cloud services are always available

C. Installing software falls under the IT process of Change Management. With SaaS, this is one process where a cloud customer's IT staff will have less work to do since the cloud provider takes care of making software available and patching it. image A, B, and D are not related to Change Management. SLAs relate to Service Level Management, the demand for IT services applies to Demand Management, and cloud service availability applies to Availability and Service Continuity Management

What business benefit is realized by migrating an application to the cloud? A. Stronger data encryption B. Less risk when there is a loss of network connectivity C. Ability to quickly scale in response to business needs D. Greater variety in virtual machine operating systems

C. Moving an application to the cloud must have business value. Cloud elasticity allows a quick response to unpredictable business demands that use computing resources. image A, B, and D are incorrect. Strong data encryption is possible without migrating an application to the cloud. Loss of network connectivity is a major risk that must be properly assessed. The cloud does not prevent a greater variety in virtual machine operating systems than could be made available within an organization.
