CDT Architecture & System Design

Question 1

What is the primary consideration when designing system architecture?

Accepted Answer

Scalability, reliability, and alignment with business requirements

Answer

System architecture must prioritize scalability, reliability, and alignment with business requirements to ensure long-term viability and value delivery.

Question 2

Which architectural pattern provides the best fault isolation?

Accepted Answer

Microservices architecture with independent service boundaries

Answer

Microservices architecture provides superior fault isolation because failures in one service do not directly affect others, improving overall system resilience.

Question 3

What role does documentation play in system architecture?

Accepted Answer

It enables team understanding, maintenance, and future development decisions

Answer

Architecture documentation is essential for team understanding, system maintenance, and informed decision-making about future development and changes.

Question 4

How should security be incorporated into system architecture?

Accepted Answer

Integrated from the initial design phase as a foundational requirement

Answer

Security must be integrated from the initial design phase (security by design) to be effective, as retrofitting security is more costly and less thorough.

Question 5

What is the benefit of using a layered architecture approach?

Accepted Answer

Separation of concerns enabling independent development and testing

Answer

Layered architecture separates concerns so each layer can be developed, tested, and modified independently, improving maintainability and team productivity.
