[Cloud] Consider Three Service Models of Cloud Computing (NIST) as discussed in the class. Which one of the following choices is NOT correct?

Application as a Service (AaaS)

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. _____ enables centralization of infrastructure in locations with lower costs (such as real estate, electricity), increase of peak-load capacity and workload being managed by the providers (IT experts), and to improve utilization and efficiency of the systems. Which one of the following choices is Correct? Select the best answer.

Multitenancy

[Cloud] Consider Five Essential Characteristics of Cloud Computing (NIST) as discussed in the class. A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. This is about _____. Select the best answer.

On-demand self-service

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. ____ is about flexibility for users with re-provisioning, adding, or expanding technological infrastructure resources. Which one of the following choices is correct? Select the best answer.

Organizational Agility

[Cloud] Consider three models of Cloud Computing (NIST) as discussed in the class. _____ is defined as the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. Which one of the following choices is correct? Select the best answer.

Platform as a Service (PaaS)

[Cloud] Consider three models of Cloud Computing (NIST) as discussed in the class. _____ is provided if the consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. Which one of the following choices is correct?

Platform as a Service (PaaS)

[Cloud] Consider Five Essential Characteristics of Cloud Computing (NIST) as discussed in the class. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time. This is about _____. Select the best answer.

Rapid elasticity

[Cloud] Consider Five Essential Characteristics of Cloud Computing (NIST) as discussed in the class. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). This is about _____. Select the best answer

Broad network access

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. Public-cloud delivery model converts capital expenditures (e.g., buying servers) to operational expenditure. This lowers effectively barriers to entry, as infrastructure is typically provided by a third party and need not be purchased for one-time or infrequent intensive computing tasks. This generates or causes one of the following benefits. Which one of the following choices is Correct?

Cost Reduction

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. Pricing on a utility computing basis can be simplified or "fine-grained" with usage-based billing options. Cloud computing get the job done for users with less in-house IT skills than needed normally. This generates or causes one of the following benefits. Which one of the following choices is Correct? Select the best answer.

Cost Reduction

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. Critical computing resources (hardware and software) are provided and maintained by the providers and can be accessed from anywhere via Internet. This generates or causes one of the following benefits. Which one of the following choices is Correct? Select the best answer.

Easier Maintenance

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. Enabling users to access systems using a web browser regardless of their location or what device they use (e.g., mobile phones, desktop or laptop) as infrastructure is off-site (provided by a third-party) and accessed via the Internet from anywhere. This generates or causes one of the following benefits .Which one of the following choices is Correct? Select the best answer.

Global Services

[Cloud] Consider the enabling technologies of Cloud Computing as discussed in the class. ______ Model is a form of distributed and parallel computing, whereby a 'super and virtual computer' is composed of a cluster of networked, loosely coupled computers acting in concert to do large tasks. Which one of the following choices is correct? Select the best answer.

Grid Computing

[Cloud] Consider Cloud Computing as discussed in the class. _______ with the use of multiple redundant sites makes well-designed cloud computing suitable for business continuity and disaster recovery. Which one of the following choices is Correct? Select the best answer.

Improved Availability

[Cloud] Consider three models of Cloud Computing (NIST) as discussed in the class. ____ refers to online services that provide high-level APIs used to abstract various low-level details of underlying network infrastructure Which one of the following choices is correct?

Infrastructure as a Service (IaaS)

[Cloud] Consider three models of Cloud Computing (NIST) as discussed in the class. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. This describes one of three models of cloud computing (NIST). Which one of the following choices is correct? Select the best answer.

Software as a Service (SaaS)

[Cloud] Consider Five Essential Characteristics of Cloud Computing (NIST) as discussed in the class. Which one of the following choices is NOT correct? Select the best answer.
