Question 2

An application has recently recorded this current profile for the utilization of the server-side components. The graph shows that within a short period of time several sudden utilization peaks have been recorded. Except for these isolated spikes the load is below 20%.

Which two components of a Platform as a Service offering primarily contribute to handle the spikes in CPU utilization and ensure that the application meets the expected performance targets (i.e. <40% CPU utilization)?

A. Continuous delivery of services allows application developers to quickly provide patches so that a new code base can be deployed and more efficiently address load surges. B. Identity management services allow strict control access to applications, prevent unauthorized access to unwanted clients, and reduce the CPU utilization of the computing nodes. C. Runtime metering and monitoring services help detect conditions that lead to peaks in CPU utilization and therefore react with the provision of additional resources. D. Auto-scaling and cloud-bursting provide the capability of acquiring additional compute nodes and by joining the resource pool can help level down the overall server load. When the load stabilizes below the expected threshold, the resources can be relinquished. E. E-mail notification services can automatically inform system administrators of the application's current state and allow them to promptly intervene with the addition of new computing resources.

Correct Answer: A,B

Question 3

What are the benefits for an organization utilizing dynamic infrastructure for running its workloads?

A. Organizations no longer need their own data centers which reduces the cost of their own IT expenditure. B. By leveraging pooled IT resources, dynamic infrastructure provides flexible IT capacity which better aligns the allocation of IT resources to business process needs of the organization C. Dynamic infrastructure is essential for the implementation of application service catalogs which reduces the time to market of such applications and increases the organization's business revenue. D. Dynamic infrastructure provides the means to achieve elastic scalability which ensures that organizations keep constant and predictable costs for the IT resources utilization.

Question 4

What does a cloud service provider have to consider when designing a new infrastructure service following the guidance of the ITIL Service Design volume?

A. A High Availability design must be developed. B. RPO and RTO must be determined. C. The service is planned to be rolled out to the production cloud environment as part of a new release of the cloud management software. D. Service Level Agreements are applied to virtual machines which are dependent on the physical infrastructure on which the virtual machine is hosted.

Correct Answer: D

Question 5

A company wants to use cloud services in the future. What needs to be done first?

A. Use cloud migration services to move their production workload into a managed cloud. B. Ask the IT department to work out a plan to reduce capital expenses using cloud services. C. Ask the IT department to order multiple virtual machines from different cloud service providers and test them for performance. D. Analyze existing business processes and determine which of them can be realized using cloud services.

Question 7

Which statement best describes the reason for using IBM Cloud Computing Reference Architecture (CCRA) adoption patterns?

A. To successfully migrate from an on-premise to an off-premise implementation and reduce hosting costs. B. To leverage the experience of many IBM cloud customer engagements to design cloud computing according to specific needs. C. To avoid network configurations which lead to poor performance of cloud services. D. The IBM CCRA adoption patterns define the integration between all IBM products.

Question 8

Which strategy makes cloud services accessible from any environment and device?

A. Cloud services are exposed and consumed via lean and standardized API based on web technologies such as REST or SOAP. B. Cloud services are exposed through a service catalog of a cloud marketplace where they can be searched and selected for use. C. Cloud services are consumed with service-specific clients which abstract away any form of heterogeneity in the client environment. D. Cloud services are implemented in Java which is largely supported by a large variety of devices (servers, mobile phones, desktops).
