Question 1

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.

Before your team begins testing, the team needs to present the performance test plan to business stakeholders

Which of the following sets of plan attributes would you recommend be part of this presentation?

ADuring the actual quiz, users logon gradually but play simultaneously. The load injection of quiz responses will not ramp up. therefore nearly 5 million quiz responses will need to be generated in a 4 second time frame with no opportunity to reach steady state. Test plans have been discussed with Operations Development and Data Center representatives and we believe the tests will tax the quiz application consistent with actual use. The JMeter monitoring system has been tuned however, with 5 million service requests over 4 seconds there is concern that the services queue measurements may be off by 25%

BThere is a less then10% chance of missing a scheduled quiz session due to performance test activities, which will likely cost the company $50,000 in lost sponsor revenue and brand damage To avoid this risk, we are scheduling Operations and Development representatives to be available during test execution We will require that the RAID 5+1 LUNs associated with the database server cluster be broken at 22 30 and the RAID 5+1 LUNs restored, ensuring the offline set mirrors back to the RAID 5 set that was under test, at 03:00

CSince the client uses an asynchronous REST web services based sessions back to the QUZRAC services cluster, the load profile will consist of virtual users running programmed load scripts based in C# that will randomly select the correct answer following a normal distribution thus modeling the typical success distribution among users The strict 4 second cap on user responses will translate into think times that are randomly selected between 1/2 second and just under 4 seconds using a uniform distribution

DIf the quiz application drops more than 1% of quiz sessions, users will likely write bad reviews on app stores and other gaming sites
Performance tests will verify that system can support at least 4 95 million users Planned tests, which include the simultaneous sessions test, will cost $350,000 Since only two quizzes are scheduled a day, performance tests on the production system during the 'down' times should be representative of what users experience. There is a 10% chance that the production system will not restored in time for a quiz.

Answer : C

Question 2

Which of the following Is a valid reason for aggregating performance test results?

ABusiness stakeholders work with detailed technical status indicators when evaluating an application's performance

BBusiness stakeholders can evaluate an application's overall performance status.

CTechnical stakeholders work with aggregated data when isolating causes of performance problems

DTechnical stakeholders work with detailed technical status indicators when evaluating an application's performance

Answer : A

Question 3

How Is transaction elapsed time determined?

Aresponse time - think time

Bresponse time + think time

Cresponse time + think time + nest time

Dresponse time + think time - nest time

Answer : B

A coworker has located various test plan elements under the standard PTP sections in a draft You have been asked to analyze the quality of the draft. The complete PTP draft cannot be provided here A content sampling of the PTP is provided.

Based on the content sample below, what is the quality of the draft document when only considering the alignment of content under standard PTP sections?

A0 misalignments, good

B1 misalignments, good

C2 misalignments good

D3 misalignments needs improvement

Answer : B

Question 5

Which of the following activities Is a valid performance oriented static testing activity?

AEvaluating resource utilization of unit level test objects

BTesting end-to-end behaviors under various load conditions.

CApplying use cases and workflows as features are integrated

DModeling of system resource requirements and/or behavior using spreadsheets or capacity planning tools

Answer : C

Question 6

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

In order to avoid cooperation among quiz participants, the answers to the multiple choice questions 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.

What input data type is most critical for the test script to incorporate to ensure that the concurrency objective will be properly tested?

AIn order to property test the concurrency objective, the test script must answer each trivia question with the same answer as every other virtual user

BIn order to property test the concurrency objective, the test script must provide a random password to the application's login system

CIn order to properly test the concurrency objective, the test script must present a unique user name to the application's login system

DIn order to properly test the concurrency objectives the test script must supply the system provided unique session ID with each answer provided

Answer : B

Question 7

Which of the following protocols would allow a test script to interact with a database management system directly?

AJDBC

BSOAP

CHTTPS

DIMAP
