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.

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 system throughput if that assumptions hold?

A1.667 million transactions/second

B1 million transactions/second

C1 million transactions/millisecond

D200.000 transactions/second

Answer : B

Question 2

Which tool is ideally the only source of execution burden experienced by the system under test?

Aload generator

Bmanagement console

Clog analysis tool

Dmonitoring tool

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

Question 4

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

The performance test team is assembling criteria for tool selection. They have identified the following criteria

* Must be able to reliably generate 5 million concurrent virtual quiz participants from multiple data centers with centralized control

* Must be compatible with REST based web services and have tight integration with RESTful APIs' OData and OpenAPI.

* Must be able to support nested transaction timers, provide centralized performance data collection and reporting, and integrate with platform monitoring agents used by the Operations team.

Which of the following criterion would best complete the provided set of criteria?

AMust protect undesirable performance results from being viewed from unauthorized users

BMust provide shell checking that checks spelling within test script comments

CMust be supported with documentation, training materials, books from known publishers, and an IDE that behaves similarly to popular in-house IDEs.

DMust have technical and software maintenance support for product versions two major revisions behind current revision

Answer : C

Question 5

How does service virtualization contribute to the performance test environment?

AService virtualization allows the load generators to produce more load per virtual instance.

BService 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.

CService 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.

DService virtualization allows the database to perform as if it were loaded with a data set many times larger than is actually loaded

Answer : B

Based on this scenario, when is It best time within this software and system update project to analyze and assess performance risks?

ADuring the requirements phase

BAfter design phase but prior to implementation phase

CRevisited over the course of the development Lifecycles

DDuring user acceptance testing and subsequent regression testing
:,

Answer : D

Question 7

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?

AFrequent 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

BGradually 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

CGradually 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

DFrequent 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.
