CMA - Certified Master Architect Quality Attribute Analysis Questions and Answers

Question 1

An architect is designing a new financial trading platform.
The business stakeholders have emphasized two critical requirements: transaction processing must be completed in under 150 milliseconds (Performance), and every transaction attempt, successful or not, must be immutably logged for regulatory compliance (Auditability/Security).
Initial analysis reveals that the intensive logging mechanism required for auditability introduces a 50ms latency, threatening the performance target.
What is the most appropriate initial action for the architect?

Accepted Answer

Document the conflict and ask the business stakeholders to prioritize one quality attribute over the other.

Answer

Select a high-throughput, low-latency logging framework and proceed with the design.

Answer

Implement an asynchronous logging mechanism to decouple it from the main transaction thread.

Answer

Proceed with a design that meets the performance target by logging only successful transactions.

Question 2

During a Quality Attribute Workshop (QAW) for a new cloud-based healthcare portal, stakeholders are brainstorming scenarios. Which of the following represents the MOST well-formed, testable quality attribute scenario for availability?

Accepted Answer

Under normal operational conditions, the system must achieve 99.99% uptime, measured monthly, with any unplanned outage lasting no more than 4 minutes.

Answer

The system should be highly available and resilient to failures.

Answer

The system must utilize redundant servers and automated failover in the cloud.

Answer

In case of a database failure, the system should recover quickly to prevent data loss.

Question 3

Which of the following best describes the primary purpose of the Attribute-Driven Design (ADD) method?

Accepted Answer

To use quality attribute requirements as the primary input for making and iterating on architectural decisions.

Answer

To evaluate a completed architecture to find risks and sensitivity points.

Answer

To create a detailed project plan and timeline based on functional requirements.

Answer

To document stakeholder business goals before any technical work begins.

Question 4

In quality attribute analysis, a design decision that improves security by adding multi-layered encryption and extensive validation often leads to increased latency and CPU usage. This situation is a prime example of a(n):
