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 toad allows the SUT performance to stabilize after each |ump 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 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.

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.

How long should it take before the user becomes aware that their last response was incorrect'

B.

What are the targeted percentages of correct responses for each of the questions asked during a quiz event?

C.

What are the targetfor CPU utilization and memory consumption for the web services platforms receiving question responses?

D.

What is the projected participation growth rate over the next nine months?

What is normally performed within the principal performance testing activity called Test Analysis and Design?

i.Determine scope of performance testing

ii.Establish action plans should performance issues arise

iii.in Create the test environment

iv.Identify risks to the performance tests

v. Determine load levels, tiring parameters, and transactions to be tested

A.

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

You performed 100 test runs that provided 5 million virtual concurrent users.You have measurements of participant concurrency at the last question for each test run In your analysis, you order all the concurrency test results by measured concurrency value from best to worst.You determine 85%. 90%. 95% and 100% values by selecting the 85th. 90th. 95th and 100th (last and worst) measured values by counting list positions starting from the best value going towards the worst until you reach the desired list position (ex. 85). Keep in mind, the results in lower list positions are as good or better than the results chosen for reporting.

After analyzing the results of the performance tests, you present the following results

85% 4.92 million valid concurrent users

90% 4.90 million valid concurrent users

95%: 4.0 millionvalid concurrent users

100%. 3.8 million valid concurrent users

Based on these results, what should you report to thestakeholders?

A.

The performance tests clearly have failed to produce a realistic and compatible load.The results should confirm the test oracle in that the 99% of five million participants concurrency objective has been achieved.If the performance test plan had worked correctly, the reported values should have been 85% 4.95, 90% 4.95, 95% 4 95 and 100% 4.95 million valid concurrent users.

B.

These results clearly show that the system update successfully supports 99% of five million participants

C.

Four samples from the first fifteen ordered test results are presented. The system update performed much worse than what is presented here. The system update has failed to meet the 99% of five million participants concurrency objective.

D.

If we pick 85 out of 100 test runs as the minimum level of reliability, thesystem update does not reliabilitymeet the 99% of five million participants concurrency target,However not all results are as bad as these

During designdiscussions the performance testteam observed that database stored procedures for several popular use casesmay be badly coded.Which of thefollowing common performance failures would bestconfirm the team's confirmwas justified?

A.

Slow response under all load levels

B.

Slow response fader moderate-to-heavy load levels

C.

Degraded response over time

D.

Inadequate or graceless error handling under heavy or over-limit load

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.

1.667 million transactions/second

B.

1 million transactions/second

C.

1 million transactions/millisecond

D.

200.000 transactions/second

How Is transaction elapsed time determined?

A.

response time - think time

B.

response time + think time

C.

response time + think time + nest time

D.

response time + think time - nest time
