Question 3

You have been asked to test the performance of a softwareand 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 shareof 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

What is the best way to address the performance testing for concurrency?

Select an option, then click Submit answer.

  • ○

    Review the asynchronous session management algorithm, review the production systems implementation including load balancing and m-memory database schema, and conduct performance tests on these production systems while there are no active quiz events.

  • ○

    Conduct a network assessment of popular mobile data providers to ensure excessive frame loss and latency do not causemore than 15% of trivia answer arrivals to occur outside acceptable arrival time.

  • ○

    Enable and schedule the quiz app to act as a virtual user on users' mobile devices while the production system is in-between quiz events. This will ensurerealistic end-to-end testing

  • ○

    Conduct performance tests on production systems while there are no active quiz events
