Maintenance testing is performed to ensure that the application continues to function correctly after changes have been made. These changes can include modifications due to new regulations, bug fixes, enhancements, or any other updates. In this case, the change in the protocol for connecting to the payment gateway due to new regulations falls under maintenance testing, as itinvolves testing the application to ensure it works correctly after the implementation of the required changes​​.

Boundary Value Analysis (BVA)focuses on test cases at the edges of partitions because defects often occur at boundaries. The temperature ranges are:

≤7 (Too cold → W)

[8-21] (Standstill → X)

[22-29] (Ideal → Y)

≥30 (Too hot → Z)

Atwo-point BVAmeans testing both thelower and upper boundary valuesof each partition.The correct selection{7,8,21,22,29,30}includes:

7 → Boundary of Too Cold (W)

8 → Lower boundary of Standstill (X)

21 → Upper boundary of Standstill (X)

22 → Lower boundary of Ideal (Y)

29 → Upper boundary of Ideal (Y)

30 → Lower boundary of Too Hot (Z)

This ensures maximum boundary coverage.

When a document management system is decommissioned, maintenance testing must include data migration testing to ensure that all documents are correctly transferred to a state archive, meeting legal requirements for long-term storage. This process verifies that data integrity is maintained during migration.

Confirmation testing is performed after a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed. Confirmation testing, also known as re-testing, is the process of verifying that a defect has been resolved by running the test case that originally detected the defect. Confirmation testing is usually done before regression testing, which is the process of verifying that no new defects have been introduced in the software as a result of changes or fixes. Therefore, option D is the correct answer.
