Showing 1-15 of 112 Questions

Question #1

What is the emerging standard for environment-based patterns?






Question #2

What are two usage templates of a cloud computing environment?

A. A developer installs a vendor-specific driver to connect to the remote deployment environment and stages its application after patches have been applied.

B. A system administrator connects to the administrative interface of an application through a proprietary tool given by the application service provider to perform management tasks.

C. A system administrator requires via e-mail the provisioning of additional resources for the application he/she manages because the system has registered a constantly increasing load in the past hour.

D. A system administrator manipulates and manages the computing nodes supporting the execution of an application through a collection of RESTful resources, which abstract the underlying infrastructure being allocated for the application

E. A web developer implements a scalable web application and uses a data caching service that has provisioned and bound to its application. The data caching service is queried through a web service and cache lookups are performed via simple GET requests

Question #3

What is the primary indicator for a poor performing cloud environment?

A. huge application server log files

B. slow cloud services response time

C. outage of the image library component

D. ineffective IT operations implementation


Question #4

What is an advantage of Storage Area Network (SAN) virtualization in cloud computing?

A. Controls communication of internal and external channels.

B. Provides Intelligent Resource Director and Channel Subsystem.

C. Centralized stored data improves utilization and reduces storage growth.

D. Ability to manage resources, both processor and I/O, not just in one single image.


Question #5

Which cloud attribute describes the ability to quickly adapt to high volatility in the amount of

A. Elasticity

B. High Availability

C. Service Delivery

D. Service Level Agreement Compliance

page: 7 Elasticity means the platform and the applications running on the platform can
handle sudden, unanticipated, and extraordinary workloads.

Question #6

What is Regulatory Compliance in the scope of cloud computing?

A. It is data encryption with easy to use key management for virtual and cloud environments.

B. It is a set of internal policies defined by the line of business that the IT department must follow.

C. It refers to externally imposed conditions on transactions in business systems and their companies.

D. It is provided by the service provider who is responsible for securing the guest operating system, applications, data, and for meeting compliance regulations.

Question #7

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. Analyze existing business processes and determine which of them can be realized using cloud services.

D. Ask the IT department to order multiple virtual machines from different cloud service providers and test them for performance.


Question #8

Which statement is true regarding a private cloud?

A. It is owned and operated for use by a single company that controls the virtualized resources and automated services.

B. It is provided by a distributed set of machines that are running at different locations while still connected to a single network.

C. Private cloud service providers own and operate the infrastructure at their data center and usually offer access only via the Internet.

D. It is composed of two or more clouds that remain distinct entities but are bound together and offer the benefits of multiple deployment models.


Question #9

Which statement is true regarding cloud networking principles?

A. They provide connections between different types of servers.

B. Latency throughput among storage networks, the data center, and the LAN is irrelevant.

C. They allow for unblocked connections between servers to enable automated movement of development tools.

D. They provide function within a management plane that stretches across enterprise and service provider networks.


Question #10

Which statement describes an elastically scalable design?

A. The application runtime keeps the load constantly under a certain threshold despite the number of requests received.

B. The system topology of the deployment includes a load balancer which spreads the requests across the server instances that host the application.

C. The application maintains historical load traces which are reviewed every week to modify the number of server instances that will be deployed for the application for the coming week.

D. Infrastructure level monitoring detects that server utilization for a given application is beyond a certain threshold, provisions additional server instances to host the application, and balances the load.

Question #11

Which statement best describes cloud bursting in the context of hybrid clouds?

A. Removing cloud resources from a hybrid cloud.

B. Moving resources from a public to a private cloud.

C. Moving cloud resources from a private to a public cloud.

D. Extending cloud resource use across hybrid clouds on demand

Another example of hybrid cloud is one where IT organizations use public cloud computing
resources to meet temporary capacity needs that can not be met by the private cloud.[71]
This capability enables hybrid clouds to employ cloud bursting for scaling across clouds.[3]
Cloud bursting is an application deployment model in which an application runs in a
private cloud or data center and "bursts" to a public cloud when the demand for
computing capacity increases. A primary advantage of cloud bursting and a hybrid cloud
model is that an organization only pays for extra compute resources when they are
needed.[72] Cloud bursting enables data centers to create an in-house IT infrastructure
that supports average workloads, and use cloud resources from public or private clouds,
during spikes in processing demands.[73]

Question #12

What is the role of the cloud service creator?

A. It can be a consumer of multiple cloud services for their own use.

B. It consumes other cloud services by leveraging and enhancing functionality exposed by the cloud service provider.

C. It is the individual, organization, or system which consumes service instances delivered by a particular cloud service.

D. It is responsible for the design, testing, implementation, and maintenance of management artifacts specific to a cloud service.


Question #13

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. RPO and RTO must be determined.

B. A High Availability design must be developed.

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.

Question #14

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

A. The IBM CCRA adoption patterns define the integration between all IBM products.

B. To avoid network configurations which lead to poor performance of cloud services.

C. To successfully migrate from an on-premise to an off-premise implementation and reduce hosting costs.

3.1.1. Adoption Pattern A collection of commonly observed functions and features that
customers desire in their solution. Where a customer starts to solve a specific business
problem, typically driven by the same business motivation. e.g. Drive down IT costs by
improving delivery time and quality, and lowering risks associated with delivery of new IT
