CPSA Architecture Fundamentals and Roles 5

Question 1

According to iSAQB, which activity is considered part of 'architecture evaluation'?

Accepted Answer

Assessing whether architectural decisions meet stakeholder concerns and quality requirements

Answer

Architecture evaluation systematically assesses whether the architecture meets its quality requirements and adequately addresses stakeholder concerns, often using methods like ATAM.

Question 2

What is the primary goal of applying the 'open/closed principle' at the architectural level?

Accepted Answer

Designing components so they can be extended with new behavior without modifying existing code

Answer

At the architectural level, the open/closed principle means designing extension points so new behavior can be added through extension rather than modification of stable components.

Question 3

A software architect discovers that two teams have independently implemented identical utility functionality in separate services. Which architectural concern does this represent?

Accepted Answer

Code and knowledge duplication creating consistency and maintenance risk

Answer

Duplicated implementations create a risk that the two copies will diverge over time, leading to inconsistent behavior and doubled maintenance effort.

Question 4

Which of the following BEST describes the architect's role in an agile project?

Accepted Answer

Continuously collaborating with teams, making just-enough decisions, and enabling evolutionary design

Answer

In agile contexts, architects collaborate continuously with teams, make decisions at the last responsible moment, and support evolutionary architecture rather than producing a complete upfront design.

Question 5

What is the main risk of over-engineering an architecture?

Accepted Answer

Unnecessary complexity increases cost, development time, and maintenance burden without proportional benefit

Answer

Over-engineering adds complexity that does not deliver business value, increasing the cost and time to build and maintain the system while often making it harder to understand.
