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 During your conversations with stakeholders you determine that an essential transaction was the quiz participant's responses to questions As you prepare to speak to stakeholders regarding their test objectives for this transaction, you develop a collection of prepared questions to ask them.
Which question is best aligned to the types of questions recommended for gathering test objectives information from stakeholders?

• A.What is the projected participation growth rate over the next nine months?
• B.How long should it take before the user becomes aware that their last response was incorrect'
• C.What are the targeted percentages of correct responses for each of the questions asked during a quiz event?
• D.What are the targetfor CPU utilization and memory consumption for the web services platforms receiving question responses?

How does service virtualization contribute to the performance test environment?

• A.Service virtualization enables the system under test to avoid functional error conditions caused by a necessary service being unavailable at the time of the performance test.
• B.Service virtualization allows the database to perform as if it were loaded with a data set many times larger than is actually loaded
• C.Service virtualization allows the load generators to produce more load per virtual instance.
• D.Service virtualization enables load balancers to operate in a distributed environment thereby creating a realistic emulation of a production environment when available system under test equipment is inferior to production.
