Question 1

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

Ai, iii true ii, iv, v false

Bii. iii true i. iv, v false

Cii, v true i, iii, iv false

Div, v true i, ii, iii false

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 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

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

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 5

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 6

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.

Given this information, what is missing to construct the operational profile for the quiz participant?

AThe network bandwidth requirements of the video stream intermissions between questions is unknown. The network bandwidth requirements of the video stream intermissions between questions is unknown

BNo survey results from past quiz winners that explore how they won No survey results from past quiz winners that explore how they won.

CThe quiz response time limit is not specified. The quiz response time limit is not specified

DThe design maximum number of users within quiz participant user class is unknown. The design maximum number of users within quiz participant user class is unknown

Answer : A

Question 7

You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application.

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?

AReview 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.

BConduct 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.

CEnable 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

DConduct performance tests on production systems while there are no active quiz events
