CPSA Quality Attributes and Scenarios 3

Question 1

Which ISO 25010 quality characteristic encompasses sub-characteristics such as co-existence and interoperability?

Accepted Answer

Compatibility

Answer

Compatibility in ISO 25010 includes co-existence (sharing an environment without interference) and interoperability (exchanging information with other systems).

Question 2

A quality scenario specifying 'under normal operations' is describing which scenario component?

Accepted Answer

Environment

Answer

The environment component of a quality scenario describes the operational context or state of the system when the stimulus occurs.

Question 3

Testability as a quality attribute is MOST directly related to which architectural concern?

Accepted Answer

Enabling isolation of components so they can be tested independently

Answer

Testability requires that components can be observed and controlled in isolation, which directly shapes architectural decisions like separation of concerns.

Question 4

Which of the following BEST describes a 'concrete quality scenario' in iSAQB terms?

Accepted Answer

A scenario with all six parts filled in with specific, measurable values

Answer

Concrete scenarios specify all six parts (source, stimulus, artifact, environment, response, response measure) with precise, measurable details.

Question 5

Mean Time To Recover (MTTR) is a response measure most associated with which quality attribute?

Accepted Answer

Recoverability (sub-characteristic of Reliability)

Answer

MTTR measures how quickly a system recovers after a failure, which is the core concern of the recoverability sub-characteristic.
