CDA Agile Architecture & Design 3

Question 1

A team is choosing between a microservices architecture and a monolith for a new DA project. What DA guidance applies?

Accepted Answer

Choose the architecture that is fit-for-purpose given the team's context and needs

Answer

DA is context-sensitive and recommends choosing the architecture that is fit-for-purpose for the specific situation rather than prescribing a single architectural style.

Question 2

Which DA concept acknowledges that both planned and emergent architectural strategies are needed in practice?

Accepted Answer

Architecture runway

Answer

The 'architecture runway' concept represents the pre-existing architectural foundation (intentional) that supports near-term features, combined with the emergent design that grows through iterations.

Question 3

In DA, 'fitness functions' are used in architecture to:

Accepted Answer

Provide objective automated checks that verify architectural characteristics are maintained

Answer

Fitness functions are automated tests or checks that verify key architectural characteristics (such as performance, security, or scalability) are preserved as the system evolves.

Question 4

Which of the following is an anti-pattern in agile architecture that DA explicitly discourages?

Accepted Answer

Big Design Up Front (BDUF) where all architecture is defined before any development

Answer

BDUF is an anti-pattern in DA because it delays value delivery, reduces flexibility, and produces designs based on assumptions that may prove incorrect.

Question 5

When a DA team identifies significant architectural risk early in a project, the recommended response is to:

Accepted Answer

Conduct a time-boxed architectural spike to explore and mitigate the risk early

Answer

DA recommends using time-boxed architectural spikes to investigate high-priority risks early, so that critical unknowns are resolved before they become costly problems.
