CPSA Architecture Evaluation Methods Questions and Answers

Question 1

An architect needs to evaluate a complex system where business stakeholders are concerned about performance and time-to-market, while technical stakeholders are focused on maintainability and security.
Which evaluation method is specifically designed to analyze these competing quality goals and identify the resulting architectural risks and compromises?

Accepted Answer

Architecture Tradeoff Analysis Method (ATAM)

Answer

Software Architecture Analysis Method (SAAM)

Answer

Architecture-Level Modifiability Analysis (ALMA)

Answer

Ad-hoc checklist review

Question 2

A key artifact created during an Architecture Tradeoff Analysis Method (ATAM) evaluation is a hierarchical structure that decomposes high-level quality goals into concrete, measurable scenarios. This artifact is used to prioritize the most important quality requirements with stakeholders. What is this artifact called?

Accepted Answer

Utility Tree

Answer

Risk Matrix

Answer

Sequence Diagram

Answer

Context Diagram

Question 3

What is the primary objective of conducting a software architecture evaluation early in the development lifecycle?

Accepted Answer

To identify and mitigate risks related to quality attributes before significant implementation effort.

Answer

To finalize the selection of programming languages and frameworks.

Answer

To generate a complete and detailed project budget.

Answer

To prove with certainty that the chosen architecture will meet all future requirements.

Question 4

An architect is preparing for an evaluation of a legacy system's architecture. The primary goal is to understand how difficult it would be to implement a specific, major new feature. The evaluation needs to be relatively quick and focused solely on the attribute of modifiability. Which method is most appropriate for this specific goal?

Accepted Answer

Software Architecture Analysis Method (SAAM)

Answer

Architecture Tradeoff Analysis Method (ATAM)

Answer

Cost-Benefit Analysis Method (CBAM)

Answer

Performance Stress Testing

Answer

The architect, the end-users, and the quality assurance team.

Answer

The project sponsor, the lead developer, and the database administrator.

Question 6

Which of the following is a primary output of a successfully conducted Architecture Tradeoff Analysis Method (ATAM) evaluation?

Accepted Answer

Answer

A fully functional prototype of the system.

Answer

A final project plan with guaranteed deadlines.

Answer

A detailed list of required third-party software licenses.
