Question No. 3
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?

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 currently preparing test scripts to function as a quiz participant.
