5. What type of high order test subjects the system to large loads over a short period of time?

Usability testing

Security testing

Volume testing

Stress testing

Stress testing is a type of high order test that subjects the system to large loads over a short period of time. This testing is done to evaluate the system's performance and stability under extreme conditions and determine its breaking point. It helps identify any weaknesses or bottlenecks in the system and ensures that it can handle heavy loads and stress without compromising its functionality or reliability.

13. Deciding how much testing is enough should take into account: i) Level of risk, including technical and business product and project risk ii) Project constraints such as time and budget iii) Size of the testing team iv) Size of the development team

I, ii, & iii are true; iv is false

I & iv are true; ii & iii are false

I & ii are true; iii & iv are false

Ii, iii & iv are true; i is false

"Size of the development team" is false because this will not necessarily determine how complex the software is and/or how much testing it needs.
"Size of the testing team" is false because this gives no indication of how much testing is needed (it relates only to our capacity to do the testing).

I & iii

Ii, iii & iv

I, ii & iii

Iv

The factor that sticks out as being wrong is iv, because it's extremely important to pay attention to people issues so the process will be a positive experience. This eliminates B & D. Then it's just a question of deciding between A & C, which are the same except that C includes "checklists". Since checklists are important, we choose C.

17. One person has been dominating the current SCRUM. Which of the following techniques should the facilitator use to bring other team members into the discussion?

Confront the person and ask that other team members be allowed to express their opinions.

Wait for the person to pause, acknowledge the person's opinion, and ask for someone else's opinion.

Switch the topic to an issue about which the person does not have a strong opinion.

Express an opinion that differs from the person's opinion in order to encourage others to express their ideas.

To prevent conflict we need to acknowledge the dominant person and then give somebody else a chance to contribute.

18. Which of the following is non-incremental test?

Top-down testing

Bottom-up testing

Big bang testing

Stab testing

Big bang testing is a non-incremental test because it involves testing the entire system as a whole, without breaking it down into smaller components or modules. In this approach, all the modules are integrated and tested together at once. This method is usually used when there are time constraints or when it is not feasible to perform incremental testing. Unlike top-down and bottom-up testing, where testing is done incrementally by gradually integrating and testing smaller units, big bang testing skips the incremental approach and tests the entire system at once. Stab testing is not a recognized term in software testing, so it cannot be considered as a valid option.

20. Before shifting into the Operational Phase, what must be done to ensure that all processes are working as planned and that the customer is ready to proceed?

Installation

Testing and Sign-Off

Process Mapping

All answer are correct

Before shifting into the Operational Phase, it is important to ensure that all processes are working as planned and that the customer is ready to proceed. This can be achieved through testing and sign-off. Testing involves checking all the processes and functionalities to ensure they are working correctly and meeting the requirements. Sign-off, on the other hand, is the formal approval from the customer indicating their satisfaction with the tested processes and readiness to proceed with the operational phase. Therefore, testing and sign-off are necessary steps to ensure the smooth transition into the operational phase.

Black Box test design techniques rely on deriving test cases based on the specification, without reference to the internal structure of the system. Decision testing relies on knowledge of the code (i.e. the internal structure), to test all the decision paths, and is a White Box technique. The other three are Black Box techniques.

22. Which of the following could be a disadvantage of independent testing?

Developer testing and independent testing will overlap and waste resources.

Communication is limited between independent testers and developers.

Independent testers are too slow and delay the project schedule.

Developers can lose a sense of responsibility for quality.

C is nonsense. A & B have some truth in them, but D is far more significant. It has certainly been shown in several organisations that when developers feel they can just "throw their work over the wall to the independent testing team", they may test a lot less.
