To determine the number of virtual users necessary for the performance test:

Total Transactions Needed:

11,700 transactions are required to simulate the operation.

Conditions of Operations:

The simulation should reflect the realistic load of departing passengers accessing the front-end application.

Virtual Users:

The number of virtual users required is equal to the total number of transactions to be generated in the test since each virtual user performs one transaction.

Thus, the correct answer isB. 11,700virtual users will be necessary to achieve the specified number of transactions under the given conditions.

Virtualizing the servers is not typically part of performance test preparation. Performance test preparation generally involves activities such as deploying the test environment, setting up the system under test, and configuring load generation and monitoring tools to ensure accurate data collection. While virtualization can be an aspect of the overall infrastructure setup, it is not a direct step in preparing for performance testing. ISTQB performance testing guidelines emphasize setting up the environment, system, and tools specifically for performance test execution.

Correlation is a critical step in preparing performance test scripts, especially when they are generated from protocol-level recordings. It involves handling dynamic values (such as session IDs or tokens) that change with each user session or transaction. Without correlation, the script fails to handle these dynamic values correctly, leading to playback errors. According to ISTQB principles, ensuring scripts are properly correlated is essential for accurate and functional test execution.
