Question 1

It is easy to add incremental amounts of mainframe computing capacity to handle increased demands for additional processing,because mainframes are easily scalable.

Accepted Answer

Mainframes are not easily scalable as they require significant planning, investment, and sometimes physical upgrades to add capacity, unlike cloud-based systems which offer more flexible scalability options.

Question 2

Developing an enterprise architecture is like planning a city.

Accepted Answer

Developing an enterprise architecture involves designing and planning the structure and components of an organization's information technology infrastructure. Just like planning a city involves designing and organizing its physical infrastructure, utilities, transportation systems, and public spaces to ensure they work together efficiently and effectively. Both require a comprehensive understanding of the organization/city's current and future needs, potential risks, and possible opportunities for growth and development.

Question 3

To meet changing business requirements,enterprise architecture must be in a state of constant evolution.

Accepted Answer

Enterprise architecture must constantly adapt to keep up with the changing needs and requirements of the business.

Question 4

The ability to respond to unanticipated changes in the business environment is a key advantage of SOA.

Accepted Answer

SOA (Service-Oriented Architecture) allows for greater flexibility and adaptability in responding to changes in the business environment. Services can be easily modified, replaced, or combined to meet changing business requirements, making it easier to respond to market or technology changes.

Question 5

Today a company can do all the right things but still fail unless it has viable enterprise architecture to guide its strategic direction.

Accepted Answer

Enterprise architecture provides a framework for aligning business objectives with technology and resources, so a company can make informed decisions and prioritize investments that support its overall strategy. Without this guidance, even the best intentions and efforts may not lead to sustainable success.

Question 6

Ineffective enterprise architecture can frustrate employees but does not jeopardize the success of an organization.

Accepted Answer

Ineffective enterprise architecture can in fact jeopardize the success of an organization by causing confusion, inefficiency, and hindering growth and innovation. It can also lead to technical debt and increased costs in the long run. Furthermore, frustrated employees may be less productive and motivated, which can ultimately impact the organization's success.

Question 7

To use SOA to build a comprehensive set of services that support a business initiative,users and IT people must define the services to be offered and design how to link and sequence the necessary services.

Accepted Answer

The answer of To use SOA to build a comprehensive...

Question 8

The tenet "form ever follows function" describes the relationship between an organization's form (enterprise architecture)and the customers' need for functionality (purpose,utility,and desired value).

Accepted Answer

The tenet "form ever follows function" indeed describes the relationship between an organization's form (enterprise architecture) and the customers' need for functionality (purpose, utility, and desired value). This means that the design of a product or system should be based on its intended function or purpose, and that its form and structure should be optimized to facilitate that function.

Question 9

All organizations should use the same approach to realizing enterprise architecture.

Accepted Answer

While there are common best practices and frameworks for enterprise architecture, each organization's unique characteristics, goals, and constraints require tailored approaches to realizing an effective enterprise architecture. It is important for each organization to assess its specific needs and resources and develop a customized enterprise architecture approach to meet those requirements.

Question 10

If an organization "stays too close to customers," bringing out only products and changes requested by the customer,the result may be less emphasis on more viable,disruptive technologies.

Accepted Answer

If an organization only focuses on fulfilling customer demands, they may not explore disruptive technologies that have the potential to revolutionize the market. As a result, they may miss out on future opportunities and fall behind competitors who are investing in innovative technologies.

Question 11

High-order thinking is vital for adapting to the new global economy.

Accepted Answer

High-order thinking skills such as critical thinking, problem-solving, creativity, and collaboration are crucial for individuals to thrive and adapt in the rapidly changing global economy. The ability to analyze information and make informed decisions, as well as to communicate effectively and work with others across cultural and geographic boundaries, are increasingly essential skills for success in many professions.

Question 12

In a client/server system,a client requests information from a server and the server performs a database request to the database server.

Accepted Answer

In a client/server system, the client requests information from the server and the server performs a database request to the database server where the information is stored.

Question 13

In software and hardware,the ideal component is one that is highly coupled and has low cohesion.

Accepted Answer

The ideal component in software and hardware should have high cohesion and low coupling. High cohesion means that the component should have a clear and focused functionality, while low coupling means that it should have minimal dependencies on other components. This makes the component more reliable, maintainable, and able to be reused in different contexts.

Accepted Answer

While customers may have a general idea of what they want, their preferences and priorities can change over time or in different contexts. It is important for businesses to actively listen to and engage with their customers in order to truly understand their needs and desires.

Question 15

Internal customers will attempt to simplify the value propositions of external customers by searching for products and services that are the most innovative.

Accepted Answer

This statement is incorrect as internal customers do not simplify the value propositions of external customers. Instead, they focus on providing support and assistance to the external customers in order to improve their satisfaction levels.

Question 16

Organizations need only to look at product differentiation and cost reduction to provide customer value.

Accepted Answer

Organizations need to look beyond product differentiation and cost reduction and focus on creating a unique customer experience to provide customer value. This includes factors such as convenience, personalization, and exceptional service.

Question 17

Centralized architecture and mainframe computing are used frequently to process high volumes of transactions,such as credit card transactions,customer billing,and automated teller machine transactions.

Accepted Answer

Centralized architecture and mainframe computing are indeed frequently used for processing high volumes of transactions like credit card transactions, customer billing, and automated teller machine transactions.

Question 18

Managers of an organization play a key role in ensuring that the proper architecture is designed and built.

Accepted Answer

Managers are responsible for overseeing the design and implementation of organizational architecture, ensuring that it aligns with the organization's strategy and goals. They work with architects, engineers, and other professionals to create a framework that supports the organization's mission and vision, and they are ultimately responsible for ensuring that it is effective and efficient.

Question 19

New solutions in software are likely to be added to older solutions,resulting in a mixture of different architectures.

Accepted Answer

As software evolves, new solutions are often incorporated into existing systems, resulting in a mixed architecture.

Question 20

The organization's operational plans determine the form.

Accepted Answer

Operational plans are detailed plans that outline how an organization will achieve its short-term objectives, but they do not determine the form of the organization itself.
