ITA - Information Technology Architecture Technology and Infrastructure Architecture Questions and Answers

Question 1

An IT architect is designing a new infrastructure for a financial services company. A key non-functional requirement is to ensure that critical system components have duplicates to prevent a single point of failure and maintain continuous operations. Which architectural principle does this requirement directly address?

Accepted Answer

Redundancy

Answer

Redundancy is the practice of duplicating critical components or functions of a system to increase reliability. In the event of a failure, the redundant component can take over, ensuring the system remains operational. This is a core principle for achieving high availability.

Question 2

A rapidly growing e-commerce company is experiencing performance degradation during peak shopping seasons. The technology architecture must be able to handle significantly increased loads without a major redesign. Which of the following architectural characteristics is most crucial to address this business need?

Accepted Answer

Scalability

Answer

Scalability refers to the ability of a system to handle a growing amount of work by adding resources. For an e-commerce platform with fluctuating traffic, designing a scalable architecture is essential to maintain performance during high-demand periods.

Question 3

When defining the Technology Architecture domain within an overall Enterprise Architecture, which of the following is the primary focus?

Accepted Answer

Detailing the hardware, software infrastructure, and network components.

Answer

The Technology Architecture domain focuses on the foundational technology infrastructure that supports the entire enterprise. This includes the physical and virtual hardware, operating systems, networking equipment, and other core technology services that applications and data rely on.

Question 4

An organization has adopted a "Cloud First" strategy as a key architectural principle. What is the primary implication of this principle for new technology and infrastructure decisions?

Accepted Answer

On-premises solutions are to be considered only after cloud-based options are evaluated and found unsuitable.

Answer

A "Cloud First" principle means that for any new solution or service, cloud-based options (SaaS, PaaS, IaaS) should be the default consideration. On-premises deployments are only chosen if there's a compelling technical, security, or regulatory reason why a cloud solution is not feasible.

Question 5

A new project requires the integration of several disparate systems, both internal and external. To ensure that these systems can communicate and exchange data effectively, which architectural principle should be prioritized?

Accepted Answer

Interoperability and Standards-Based Integrations

Answer

Interoperability is the ability of different systems and organizations to work together (inter-operate). By using standards-based integrations (like REST APIs), an architect ensures that components can be connected and can exchange information in a consistent, predictable manner.
