   A test manager is planning reliability testing for a new online payment system. The operational profile shows that 'authorize payment' occurs 60% of the time, 'refund' 30%, and 'void' 10%. The team has a budget for 100 test cases. The business has stated that refunds are the most critical operation because errors there cause regulatory fines. How should the test manager allocate the 100 test cases?

   • AAllocate all 100 cases to 'refund' because it is the most critical operation.
   • BAllocate 60 cases to 'authorize payment', 30 to 'refund', and 10 to 'void' to match the operational profile exactly.
   • CAllocate 33 cases to each operation to ensure equal coverage.
   • DAllocate 40 cases to 'authorize payment', 40 to 'refund', and 20 to 'void' to give extra weight to the critical refund operation.

   A test manager wants to construct an operational profile for a mobile banking app. The team has collected data from production for one month, but the data is incomplete: the logging for the 'transfer funds' operation failed for the first two weeks. The team also has access to business analysts who can estimate usage. What is the best way to handle this missing data when constructing the profile?

   • ACombine the partial log data with estimates from business analysts to assign a probability to 'transfer funds', and then normalize all probabilities to sum to 1.
   • BWait until a full month of clean data is available before constructing the profile, even if it delays the testing schedule.
   • CUse the two weeks of available data for 'transfer funds' and extrapolate it to the full month, then calculate probabilities for all operations.
   • DExclude the 'transfer funds' operation from the profile entirely because the data is unreliable.

   A test analyst is constructing an operational profile for a new online banking system. The system has several categories of operations: balance inquiry, fund transfer, bill payment, and customer service chat. The analyst has collected data from a pilot deployment. Which step is essential when constructing the operational profile?

   • AUse only the operations that are considered business-critical, regardless of their frequency, and assign them probabilities.
   • BAssign each operation a probability based on its frequency in the pilot data, ensuring the probabilities sum to 1.
   • CIdentify the most complex operation and assign it the highest probability to ensure it is tested thoroughly.
   • DList all operations in alphabetical order and assign equal probabilities to each.
