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

• A.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.
• B.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 ensure realistic end-to-end testing
• C.Conduct a network assessment of popular mobile data providers to ensure excessive frame loss and latency do not cause more than 15% of trivia answer arrivals to occur outside acceptable arrival time.
• D.Conduct performance tests on production systems while there are no active quiz events

What test script operating conditions are risks to a performance test's validity?
i. Record insertions align with transaction objective
ii. Component failure within the system under test
iii. Load generator produces low load level
iv. Database log remains synchronized with load generators time source
v. Virtual users authenticate with distinct IDs

• A.i, iii true ii, iv, v false
• B.ii. iii true i. iv, v false
• C.iv, v true i, ii, iii false
• D.ii, v true i, iii, iv false

Which of the following protocols would allow a test script to interact with a web server for ecommerce transaction testing?

• A.IMAP
• B.JDBC
• C.SOAP
• D.HTTPS

Which Is a valid reason for why performance testing load would be applied to the SUT in a ramp-up pattern during a performance test?

• A.Frequent sudden significant increases of load ensures the SUT remains in a transient performance condition as it responds to each new large increase in load thus exhibiting consistent behavior that results in measurements that are more reliable.
• B.Gradually increasing the load ensures the SUT remains in a transient performance condition as it responds to the new increase in load thus exhibiting realistic behavior that improves the realism of the performance test
• C.Gradually increasing the load allows the SUT performance to stablize after each progressive increment of load thus exhibiting consistent behavior that results in measurements that are more reliable
• D.Frequent sudden significant increases of toad allows the SUT performance to stabilize after each |ump in load thus exhibiting consistent behavior that results in measurements that are more reliable
