Grid computing offers several business benefits, including improved productivity and collaboration of virtual organizations and respective computing and data resources, allowing widely dispersed departments and businesses to create virtual organizations to share data and resources, and providing robust and infinitely flexible and resilient operational architectures. Therefore, all the options mentioned in the question are correct.

Question 5

Which of the following is not a component in an SOA architecture?
A) Business Model
B) Service Model
C) Implementation Model
D) Maintenance Model

Accepted Answer

The Maintenance Model is not typically considered a component in an SOA architecture. The other three components - Business Model, Service Model, and Implementation Model - are all key parts of a service-oriented architecture. The Business Model defines the business processes and policies that are supported by the architecture, while the Service Model specifies the specific services that are offered by the architecture. The Implementation Model outlines the technology and infrastructure that is required to support the services and business processes. Maintenance is an ongoing activity that supports all of these components but is not a discrete part of the architecture itself.

Question 6

What is a SOA service?
A) A simple business task
B) A complex business process which only delivers value to a consumer
C) All business processes dealing with customer credit
D) All business processes dealing with employee payroll

Accepted Answer

This is the definition of SOA service.

Question 7

What is loose coupling?
A) The capability of two or more computer systems to share data and resources, even though they are made by different manufacturers
B) A markup language for documents containing structured information
C) The capability of services to be joined together on demand to create composite services or disassembled just as easily into their functional components
D) None of the above

Accepted Answer

Loose coupling refers to the ability of services in a service-oriented architecture (SOA) to be joined together or disassembled without being tightly bound together. This means that changes made to one service will not affect the functioning of others, and services can be easily replaced or upgraded without causing disruption to the system as a whole. Choice A refers to interoperability, while choice B refers to a markup language (XML) rather than a software system architecture concept. Choice D is incorrect as there is a correct choice that matches the definition of loose coupling.

Question 8

Which of the following is an example of loose coupling?
A) Common customer identification
B) Update customer address
C) Update account balance
D) Common customer account balance

Accepted Answer

Loose coupling refers to a design principle where components have little or no knowledge of the definitions of other separate components. "Common customer identification" is an example of loose coupling because it allows different systems to identify a customer without needing to know the details of each other's implementations.

Question 9

Which of the following is a common service example of loose coupling?
A) Conversion of currency
B) Update customer address
C) Delete customer email address
D) All of the above

Accepted Answer

Conversion of currency is a common service example of loose coupling because it involves using a third-party service or API to perform the conversion, rather than having a tightly-coupled system that handles everything in-house. Loose coupling allows for better scalability and flexibility in the system. Update and delete customer information are less clear cut examples of loose coupling and could potentially be handled in a tightly-coupled system.

Question 10

What enables organizations to optimize computing and data resources, pool them for large capacity workloads, share them across networks, and enable collaboration?
A) Virtualization
B) Interoperability
C) Loose Coupling
D) Grid Computing

Accepted Answer

With grid computing, organizations can optimize computing and data resources, pool them for large capacity workloads, share them across networks and enable collaboration.

Question 11

What is a framework for dividing the resources of a computer into multiple execution environments?
A) Loose Coupling
B) Interoperability
C) Virtualization
D) SOA

Accepted Answer

Virtualization is a framework for dividing the resources of a computer into multiple execution environments. It allows running multiple operating systems and applications on a single physical machine, creating virtualized resources that can be allocated as needed. Loose coupling refers to the degree to which components or modules in a system are dependent on each other, while interoperability refers to the ability of different systems and components to work together seamlessly. SOA (Service-Oriented Architecture) is a design approach for building distributed systems that are composed of loosely-coupled, interoperable services.

Question 12

Which of the following reflects Moore's Law?
A) New generations of chips deliver double the processing power as the previous generation
B) New generations of chips deliver triple the processing power as the previous generation
C) New generations of chips deliver quadruple the processing power as the previous generation
D) Impossible to determine

Accepted Answer

Moore's Law states that the number of transistors on a computer chip will double every 18-24 months, which results in a doubling of processing power. Therefore, choice A reflects Moore's Law. Choices B and C are not consistent with the law, and choice D is not a valid option as there is a clear answer.

Question 13

Which of the following is not an additional benefit of virtualization?
A) Rapid application deployment
B) Dynamic load balancing
C) Ease of use for customer relationship management systems
D) Streamlined disaster recovery

Accepted Answer

Virtualization provides benefits such as rapid application deployment, dynamic load balancing, and streamlined disaster recovery. However, it does not directly affect the ease of use for customer relationship management systems, which is more dependent on the design and implementation of the CRM software itself.

Question 14

Which of the following is a trend responsible for moving virtualization into the spotlight?
A) System administration costs increasing
B) Data centers running out of space
C) Increasing energy costs
D) All of the above

Accepted Answer

All of the given options- increasing system administration costs, running out of data center space, and increasing energy costs- are responsible for moving virtualization into the spotlight. Virtualization helps reduce system administration costs by reducing the need for physical hardware and simplifying management. By consolidating multiple physical servers into virtual machines, data centers can save physical space. Additionally, virtualization allows for more efficient use of resources, reducing energy costs.

Question 15

Which of the following is an example of a loosely coupled service?
A) The recovery of a university course registration system
B) The updating of a university course registration system
C) The backup of a banking system
D) The cellular telephone system

Accepted Answer

A loosely coupled service is one where the components can operate independently and do not need to have intimate knowledge of each other's internal workings. The cellular telephone system is an example of a loosely coupled service as each device can operate independently and connect to the network without needing to know the details of the other devices or the network infrastructure. The recovery, updating, and backup of university and banking systems typically involve tightly coupled components that require intimate knowledge of each other's internal workings.

Question 16

What is the ability to present the resources of a single computer as if it is a collection of separate computers, each with its own virtual CPUs, network interfaces, storage, and operating system?
A) System virtualization
B) Server virtualization
C) Desktop virtualization
D) All of the above

Accepted Answer

System virtualization, server virtualization, and desktop virtualization are all types of virtualization that allow a single computer to be presented as multiple virtual computers.

Question 17

What are the key technical concepts of SOA?
A) Processes, integration, tight coupling
B) Services, interoperability, loose coupling
C) Services, processes, loose coupling
D) Processes, interoperability, tight coupling
Services, interoperability, and loose coupling are the key technical concepts of SOA.

Accepted Answer

Services are at the heart of SOA, and they are designed to be interoperable with each other. Loose coupling allows for greater flexibility and adaptability in the system. Processes and tight coupling can be used in SOA, but they are not key technical concepts.

Question 18

Which of the following is not part of a typical SOA solution?
A) Integrate information to make it more accessible to employees
B) Understand how business processes interact to better manage administrative costs
C) Decrease people productivity with better business integration

Question 19

What is an aggregation of geographically dispersed computing, storage, and network resources, coordinated to deliver improved performance, higher quality of service, better utilization, and easier access to data?
A) Virtualization
B) Interoperability
C) Loose Coupling
D) Grid Computing

Accepted Answer

Grid computing is the aggregation of geographically dispersed computing, storage, and network resources, coordinated to deliver improved performance, higher quality of service, better utilization, and easier access to data. Virtualization, interoperability, and loose coupling are related concepts, but they do not specifically refer to the coordination of geographically dispersed resources in the same way that grid computing does.

Question 20

What is a business-driven IT architectural approach that supports integrating a business as linked, repeatable tasks or services?
A) Business continuity planning
B) Open systems
C) Service oriented architecture
D) Web services

Accepted Answer

Service-oriented architecture (SOA) is a business-driven IT architectural approach that supports integrating a business as linked, repeatable tasks or services. SOA allows for the organization of business processes into a set of services that can be reused, combined, and orchestrated to create new or enhanced business capabilities. This approach enables the agility and flexibility needed to quickly and easily adapt to changing business needs, making it a popular choice for modern system integration and application development. Business continuity planning and open systems are not directly related to the described approach, and while web services can be a component of SOA, it alone does not fully capture the essence of the approach.
