A performance test team is testing a chat application that uses WebSocket for real-time messaging and HTTPS for user authentication. The test tool supports both protocols. What is the most important consideration when designing the test to accurately measure user experience?

Use only WebSocket for the test because it is the primary communication method.

Ensure the test script includes both HTTPS and WebSocket interactions in the same user session.

Measure the response time of the HTTPS authentication separately from the WebSocket messaging.

Use only HTTPS for the test because WebSocket is not a standard protocol for performance testing.

What is the purpose of identifying an operational profile in performance testing?

To document the test team's roles and responsibilities.

To understand how users actually use the system, so that realistic load can be simulated.

To determine the exact number of servers needed for the production environment.

To define the security requirements for the application.

A performance test team is defining transactions for an online banking application. The business has identified the following user actions: login, view account balance, transfer funds, and logout. Which of the following is the most appropriate way to define a transaction for the 'transfer funds' process?

Combine 'transfer funds' with 'view account balance' into one transaction to reduce test execution time.

Treat the entire 'transfer funds' process as a single transaction, including all steps from initiation to confirmation.

Define 'transfer funds' as a single transaction that includes only the final confirmation step.

Break 'transfer funds' into separate transactions for each HTTP request to get more granular data.

An SLA states that 'the system must support 1,000 concurrent users with an average response time of less than 2 seconds.' Which of the following is the most appropriate measurable performance test objective derived from this SLA?

Ensure the system is reliable and performs well under normal conditions.

Verify that the system can handle 1,000 concurrent users with an average response time below 2 seconds.

Test the system with as many users as possible to find the maximum capacity.

Check that the system does not return errors during peak usage.

When communicating performance test results to stakeholders, which of the following is the most effective approach?

Present raw performance data and detailed technical logs to all stakeholders.

Only share results if the test passes; otherwise, keep failures internal to avoid alarm.

Send a lengthy email with all test scripts and configuration details.

Summarize results in terms of business impact, such as whether SLAs were met and risks identified.

Part of the Performance Testing Tasks domain, which makes up ~20% of our current practice bank. ISTQB does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 2–3 from this objective — we provide 23 practice questions to prepare you well beyond it.
