CMA Quality Attribute Analysis 2

Question 1

Which quality attribute scenario component describes the stimulus that triggers a system response?

Accepted Answer

Source

Answer

The source is the entity (person, system, or event) that generates the stimulus in a quality attribute scenario.

Question 2

A system must recover from a database failure and resume normal operations within 30 seconds. Which quality attribute does this scenario primarily address?

Accepted Answer

Availability

Answer

Availability is concerned with system uptime and recovery time from failures, measured here by a 30-second recovery window.

Question 3

What is the primary purpose of a quality attribute utility tree in architecture evaluation?

Accepted Answer

To prioritize quality attributes by business value and risk

Answer

A utility tree organizes and prioritizes quality attribute scenarios based on their business importance and technical risk.

Question 4

Which architectural tactic directly addresses the modifiability quality attribute by reducing dependencies between modules?

Accepted Answer

Encapsulation

Answer

Encapsulation hides internal implementation details, reducing coupling and making modules easier to modify independently.

Question 5

In the context of quality attribute analysis, what does 'response measure' define?

Accepted Answer

The quantifiable criterion used to assess whether a response is acceptable

Answer

The response measure provides a testable, quantifiable criterion — such as latency in milliseconds — to determine if the system's response meets requirements.
