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.

You are working on an internet banking project. Your company is offering this product to the financial market. For each new customer, some customization will typically be needed. To make the product successful there is a strong focus during development on a reliable and maintainable architecture. To support architectural reviews, a checklist will be developed. Within the checklist specific sections will be attributed to reliability and maintainability.
Which question from the list below should you include in the maintainability section of the architectural review checklist?

• A. Will the system use n-version programming for critical components?
• B. Does the password protection of the system adhere to the latest regulations?
• C. Will the user interface be implemented independently from the other software modules?
• D. Does the system have user-friendly error messages?

Which of the following statements about performance testing tools is NOT correct?

• A. Performance testing tools generate a load by simulating a large number of virtual users following their designated operational profiles to generate specific volumes of input data.
• B. Typical metrics and reports provided by performance testing tools include the number of simulated users throughout the test, and the number and type of transactions generated by the simulated users, and the arrival rate of the transactions.
• C. Performance testing tools typically drive the application by simulating user interaction at the graphical user interface level to more accurately measure response times.
• D. Significant factors to consider in the implementation of performance testing tools include the flexibility of the tool to allow different operational profiles to be easily implemented, and the hardware and network bandwidth required to generate the load.

Subject to testing is a software system (COTS) for Project Administration and Control (PACS). PACS is a multi-project system for controlling the project time, e.g., in terms of scheduling and tracking, and managing the productivity of projects, e.g., in terms of effort and deliverables.
During various interviews with stakeholders the following information was gathered:
* Using PACS is not business critical. There is no impact such as high financial losses or problems to the operational continuity of an organization. Its application is not critical since the software package does not support directly the operational, or the primary, business processes of an organization. It supports (project) management in the project planning and tracking process. Of course, it will be highly annoying for users if the system "goes down" from time to time. Although this does not have a high impact for the business process as a whole, the Mean Time Between Failures (MTBF) still needs to be at a good level to be successful in the market.
* Users of PACS typically have an academic educational level, but have no prior experience with this particular type of project management software. The system will be used by a large number of users within an organization.
* The system will be used on a regular basis, e.g., several times per day by project managers and several times per week by project employees. This means that the system will not be used very intensively, often only for some data input or an information request. Its usage is not considered to be very time-critical.
* The data is recorded on-line and real-time. The system is expected to run in multiple hardware environments in various network environments. It is also expected that changes in the operational environments will happen in the upcoming period that also need to be supported.
Based on the information provided by the stakeholder, which combination of non-functional quality characteristics should you propose to test as part of your test approach?

• A. Performance efficiency and Portability
• B. Reliability and Performance efficiency
• C. Reliability and Portability
• D. Security and Reliability
