How does a performance test script determine the duration of a request?

• Starting a counter when the result is received and stopping the counter when the request is made
• Entering an interrupt service routine when the request is made and returning when the result is received.
• Forking a child of itself and then blocking when the request is made and resuming operations when the result is received
• Starting a timer when the request is made and stopping the timer when a result for the request is received.

During design discussions the performance test team observed that database stored procedures for several popular use cases may be badly coded. Which of the following common performance failures would best confirm the team's confirm was justified?

• Slow response under all load levels
• Slow response fader moderate-to-heavy load levels
• Degraded response over time
• Inadequate or graceless error handling under heavy or over-limit load

Which section of a performance test script is typically responsible for ensuring the script will have the right values and communication settings during execution?

• main section
• clean-up section
• initialization section
• timer section

Which of the following activities Is a valid performance oriented static testing activity?

• Evaluating resource utilization of unit level test objects
• Testing end-to-end behaviors under various load conditions.
• Applying use cases and workflows as features are integrated
• Modeling of system resource requirements and/or behavior using spreadsheets or capacity planning tools

What is normally performed within the principal performance testing activity called Test Planning and Control?i. Determine scope of performance testingii. Organize test cases into performance test proceduresiii. Create the test environmentiv. Identify risks to the performance testsv. Determine load levels, timing parameters, and transactions to be tested

You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application. The quiz app is available on major app stores serving English-speaking users. The number of concurrent users planned for is 5 million. Winning quiz participants are promised a share of an allocated cash prize Once participants start playing, their quiz sessions must not be lost especially if all previous questions were answered correctly. The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4 95 million sessions) until the last answer has been successfully recorded.An essential operational profile you identified is the quiz participant. Your operational profile discovery efforts have yielded a number of profile attributes. A quiz participant will answer twelve questions if they manage to answer the first eleven correctly Every user is made aware of a new question nearly simultaneously. The quiz user has limited time to respond using a mobile application. They are unable to respond to subsequent questions after they incorrectly answer a question. However, the quiz participant continues to see new questions even though they may have responded incorrectly to a previous question If they manage to answer all twelve questions correctly, the quiz application notifies them that they have tentatively won (subject to formal verification) an equal share of a cash prize of an amount set for the particular quiz event In addition to this individualized interaction, a broadcast video stream is presented in the quiz app providing entertaining commentary quiz event coordination, event status and answer explanations.The average quiz event duration when measured from when the first question is presented to the last answer is reviewed is fifteen minutes. Over the fifteen minutes, twelve questions are presented to quiz participants. After making the following assumptions:1. Questions must be responded to within a four second window;2. Question responses will be sent evenly across this window of time (resulting in an average responder time of two seconds);3. The designed maximum number of concurrent users will attempt the first question;4. There will be no functional issues when handling the load.5. The average time from response reception to database commitment is 1000 milliseconds under maximum concurrent usage.What is the approximate maximum average system throughput if that assumptions hold?

• 1.667 million transactions/second
• 1 million transactions/second
• 1 million transactions/millisecond
• 200.000 transactions/second
