ISQI CTFL-PT Exam : ISTQB Certified Tester Foundation Level-Performance Testing

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 storesserving 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 systemthroughput if that assumptions hold?

• A. 200.000 transactions/second
• B. 1.667 million transactions/second
• C. 1 million transactions/millisecond
• D. 1 million transactions/second

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

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

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 promiseda 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 In order to avoid cooperation among quiz participants, the answers to the multiple choice questions are listed randomly Confidence in the game's fairness requires that a registered user originate from only one quiz client device Every user must respond over the same short window of time in order to avoid external assistance and learning the official answer before responding.Only participants who respond correctly may answer the next question Any activity that appears to violate expected behavior of a rule-following participant will cause the client session to be rejected.
You are developing test script code that handles quiz question responses. To do this you need to ensure that the script emulates the production quiz app client's logic in terms of rule following and client-backend interface specification.
Based on the question description provided, which is one test script behavior you would implement in order to ensure the test script successfully delivers the operational and load profile of a quiz participant?

• A. Use the date-time clock in order to submit question responses on a synchronized schedule with each instance
• B. Recognize whether the previous question response was correct
• C. Set the device identifier as a constant to ensure all virtual user instances use the set value
• D. Randomly select the maximum think time limit used to delay question responses.

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.
Which of thefollowingIs a proper load profilefor thequiz participants?

• A. Steady ramp-up of quiz response transactions from one million until the design maximum is reached within the first three questions.The maximum is sustained until question twelve
• B. 240.000,000 question responses per hour
• C. Stepped ramp-up of quiz response transactions from one million increasing by a one million after each question until the design maximum is reached.The minimum is sustained until question twelve.
• D. Maximum number of planned concurrent quiz responses will occur at the first question with a steppedramp-down after each question.The size of each step and the final number of nearly simultaneous quiz responses are random values within historical ranges observed over the last three

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

• A. clean-up section
• B. main section
• C. timer section
• D. initialization section
