Question 3

Which of the following best describes the primary purpose of an N-Tier application architecture?

Accepted Answer

To separate concerns by dividing the application into logical layers, such as presentation, business logic, and data access.

Answer

To couple all application components tightly for higher performance.

Answer

To enable direct communication between the user interface and the database.

Answer

To consolidate all business logic into a single, monolithic service for easier management.

Question 4

A retail company is building a cloud-native application. The architects have decided to prioritize stateless processing for most of the application's components. What is the main benefit of this architectural choice in a cloud environment?

Accepted Answer

It enhances scalability and fault tolerance by not storing session data on the instance.

Answer

It simplifies data consistency and transactional integrity.

Answer

It reduces the need for a robust data access layer.

Answer

It minimizes network latency between application components.

Question 5

In the context of enterprise data architecture, what is the primary role of data modeling?

Accepted Answer

To create a conceptual blueprint of the data, defining its structure, relationships, and constraints.

Answer

To define the physical hardware specifications for database servers.

Answer

To write the ETL (Extract, Transform, Load) scripts for data migration.

Answer

To establish security policies and access controls for the data.

Question 6

An organization's enterprise architect is evaluating two application architecture patterns: Monolithic and Microservices. The project is a small, internal application with a limited budget, a small development team, and a need for rapid initial deployment. Which pattern is likely the most suitable choice and why?

Accepted Answer

Monolithic, because it offers lower initial complexity, simplified deployment, and is easier for a small team to manage. [13, 14]

Answer

Microservices, because it allows for greater technological diversity and scalability from the start.

Answer

Microservices, because it enforces a loosely coupled architecture, which is always superior.

Answer

Monolithic, because it is inherently more secure due to having a single attack surface.
