B. Procedures and standards

Explanation
Procedures and standards are used within individual workbenches to produce the right output products. Procedures provide a step-by-step guide on how to perform a specific task, ensuring consistency and accuracy in the output. Standards, on the other hand, define the criteria and guidelines that need to be followed during the process to maintain quality and meet the desired outcome. By utilizing procedures and standards, individuals can ensure that their work is done correctly and in accordance with established guidelines, resulting in the production of the right output products.

Which is not the testing objectives
- A.
  
  Finding defects
- B.
  
  Gaining confidence about the level of quality and providing information
- C.
  
  Preventing defects
- D.
  
  Debugging defects
Correct Answer
D. Debugging defects

Explanation
The objective of testing is to find defects, gain confidence about the level of quality, and provide information. Preventing defects is also an objective of testing as it aims to identify and fix issues before they occur. However, debugging defects is not a testing objective. Debugging is the process of identifying and fixing defects after they have been found, which is typically done by developers rather than testers.

Bug life cycle
- A.
  
  Open, Assigned, Fixed, Closed
- B.
  
  Open, Fixed, Assigned, Closed
- C.
  
  Assigned, Open, Closed, Fixed
- D.
  
  Assigned, Open, Fixed, Closed
Correct Answer
A. Open, Assigned, Fixed, Closed

Explanation
The correct answer is "Open, Assigned, Fixed, Closed." In the bug life cycle, the first step is to identify and report the bug, which is represented by the "Open" status. Once the bug is acknowledged and assigned to a developer, it moves to the "Assigned" status. The developer then works on fixing the bug, which leads to the "Fixed" status. Finally, after the bug is verified and confirmed to be resolved, it is marked as "Closed." This sequence represents the typical flow of a bug through its life cycle.

Which is not the software characteristics
- A.
  
  Reliability
- B.
  
  Usability
- C.
  
  Scalability
- D.
  
  Maintainability
Correct Answer
C. Scalability

Explanation
Scalability is not a software characteristic because it refers to the ability of a system to handle increasing workloads by adding more resources. While scalability is an important consideration for software systems, it is not a characteristic of the software itself. Reliability, usability, and maintainability, on the other hand, are all software characteristics. Reliability refers to the software's ability to perform its intended functions without failure, usability refers to the ease of use for end-users, and maintainability refers to the software's ability to be easily modified and updated.

Which is not a testing principle
- A.
  
  Early testing
- B.
  
  Defect clustering
- C.
  
  Pesticide paradox
- D.
  
  Exhaustive testing
Correct Answer
D. Exhaustive testing

Explanation
Exhaustive testing is not a testing principle because it is practically impossible to test all possible combinations and inputs of a system. It is not feasible to test every single scenario due to time, resources, and budget constraints. Instead, testing efforts should be focused on critical areas and high-risk scenarios to ensure maximum coverage and effectiveness.

‘X’ has given a data on a person age, which should be between 1 to 99. Using BVA which is the appropriate one
- A.
  
  0,1,2,99
- B.
  
  1, 99, 100, 98
- C.
  
  0, 1, 99, 100
- D.
  
  –1, 0, 1, 99
Correct Answer
C. 0, 1, 99, 100

Explanation
Using Boundary Value Analysis (BVA), the appropriate values to test for a person's age, which should be between 1 to 99, would be the minimum value (0), the minimum valid value (1), the maximum valid value (99), and the maximum value (100). This is because BVA focuses on testing the boundaries and values just outside of them to ensure that the system handles them correctly. By including these specific values, we can verify if the system properly handles the age limits and any potential edge cases.

- A.
  
  Planning and control
- B.
  
  Test closure activities
- C.
  
  Analysis and design
- D.
  
  None
Correct Answer
D. None

Explanation
The given options are all fundamental test processes except for "None". "None" does not represent a specific test process, but rather indicates that there is no fundamental test process missing from the options provided. Therefore, "None" is not a fundamental test process.

- A.
  
  Check the memory leaks
- B.
  
  Check the robustness
- C.
  
  Check the branch coverage
- D.
  
  Check the decision tables
Correct Answer
D. Check the decision tables

Explanation
Component testing is a type of testing that focuses on testing individual components or units of a software system. It involves testing the functionality and behavior of each component in isolation. Checking the decision tables, on the other hand, is not a specific type of component testing. Decision tables are used for designing and documenting complex business rules or logic, but they are not directly related to testing the functionality or behavior of individual components. Therefore, checking the decision tables would not be considered a component testing activity.

  Plan, Do, Correct, Act
- C.
  
  Plan, Debug, Check, Act
- D.
  
  Plan, Do, Check, Accept
Correct Answer
A. Plan, Do, Check, Act

Explanation
PDCA stands for Plan, Do, Check, Act. This is a four-step management method used for continuous improvement of processes and products. The first step, Plan, involves setting objectives and creating a plan to achieve them. The second step, Do, involves implementing the plan and carrying out the necessary actions. The third step, Check, involves evaluating the results and comparing them to the objectives. The final step, Act, involves taking corrective actions based on the evaluation and making necessary adjustments for improvement. This cycle is repeated continuously to ensure ongoing improvement.

- A.
  
  System testing
- B.
  
  Acceptance testing
- C.
  
  Integration testing
- D.
  
  Smoke testing
Correct Answer
B. Acceptance testing

Explanation
Acceptance testing is the process of evaluating a system's compliance with business requirements and determining if it meets the needs of the end-users. Contract and regulation testing, as part of acceptance testing, ensures that the system adheres to specific contractual agreements and regulatory standards. This type of testing verifies if the system meets legal and industry-specific requirements, such as data privacy laws or financial regulations. Therefore, the correct answer is acceptance testing.
