Cloud Computing

[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 enabling technologies of Cloud Computing as discussed in the class. ______ Model is broadly to any distributed application with 2-layers to distinguish service providers and service requestors. Which one of the following choices is correct? Select the best answer.

Client-Server

[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. 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. 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 Five Essential Characteristics of Cloud Computing (NIST) as discussed in the class. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. This is about _____. Select the best answer.

Measured service.

[Cloud] Consider the major benefits of Cloud Computing as discussed in the class. ____ is about sharing of resources and costs with a large pool of users Which one of the following choices is Correct? Select the best answer.

Multitenancy

[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 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? Select the best answer.

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. The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. This is about _____. Select the best answer.

Resource pooling

[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.

Telemarketing service.

[Cloud] Consider the Cloud Computing as discussed in the class. Cloud Computing is possible with the availability of ____. Which one of the following choices is NOT correct?

low-cost low-capacity networks

[Cloud] Consider the Cloud Computing as discussed in the class. Cloud providers typically use a(n) ______ model which let user be accountable to its own use only. Which one of the following choices is Correct?
