Which of the following is a valid reason for including performance testing in a test approach?

• A.To mitigate the risk of long response times to defects reported by users and/or customers.
• B.To evaluate the ability of a system to handle increasing levels of load.
• C.To reduce the threat of code insertion into a web page which may be exercised by subsequent users.
• D.To evaluate the system's tolerance to faults in terms of handling unexpected input values.

The following characteristics were identified during an early product risk-assessment for a software system:
* the software system needs to manage synchronization between various processes
* microcontrollers will be used that will limit product performance
* the hardware that will be used will make use of timeslots
* the number of tasks supported in parallel by the software system is large and are often highly complex.
Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?

• A.Portability testing
• B.Time-behaviour testing
• C.Security testing
• D.Maintainability testing

Within an embedded software project, the maintainability of the software is considered to be critical. It has been decided to use static analysis on each delivered software component.
Which of the following metrics is NOT a maintainability metric typically used with static analysis?

• A.Number of Lines of Code (LOG)
• B.Number of Function Calls
• C.Mean Time Between Failures
• D.Comment Frequency

A software company based in Spain that develops mobile applications expects many small updates in the future, e.g., due to changing configurations and customer feedback. The company also wants to focus on being able to change the software effectively and efficiently during initial development without introducing new defects.
Which maintainability sub-characteristic should be covered by the test approach during the initial development?

• A.Re-usability
• B.Modifiability
• C.Modularity
• D.Analysability

Which of the following is a valid reason for including security testing in a test approach?

• A.Software changes will be frequent after it enters production.
• B.To evaluate the ability of a system to handle peak loads at or beyond the limits of its anticipated or specified workloads
• C.To provide measurements from which an overall level of availability can be obtained.
• D.There is a threat of unauthorized copying of applications or data.
