ISTQB ATM Exam Questions Instant Access - No Installation Required

Question 1

You can count on well-written requirements, but you can't count on an adequate contribution of the stakeholders to the quality risk analysis. You have to mitigate the insufficient contribution of the stakeholders because the risk-based testing approach shall minimize the product risks. Your test team has one expert tester in security testing. Which of the following test activities would you expect to be the less important in this context? K4 3 credits

AExtract from the defect tracking system of the previous project all the security defects and failures, and classify them to support design and execution of specific tests

BAutomate all functional and non-functional system tests

CApply systematic and exploratory testing for integration and system test

DPerform exploratory testing sessions with adequate charters covering security aspects

Answer : B

Question 2

Which of the following statements describing how identified product quality risks should be mitigated and managed, is true?

K2 1 credit

AThe extent of re-testing and regression testing activities should be based on the risk level

BThe identification of new risks, the re-assessment of the level of existing risks and the evaluation of the effectiveness of risk mitigation activities should only occur at the very beginning of a project

CRisk mitigation of product quality risks can be effective only after starting test execution

DThe priority of the development and execution of tests should not be based on the risk level but only on the likelihood

Answer : A

Question 3

Assume you are working on a CAS (Conditional Access System) for Pay-TV that allows the access, selection and transfer of services and media to authorized users. Authorized users can choose their services through different channels: Web Customer Portal, IVR (Interactive Voice Response), Call Centre and SMS. The system uses a Smart Card to receive and decrypt the broadcasted encrypted control words which allow decrypting pay-per-view TV. Every authorized user must have a Smart Card and a Set-Top Box to view the contents.

The following is an excerpt from the product risk analysis document:

Both likelihood and impact have been rated on the following scale: (1 -- Very low, 2 -- Low, 3 --Medium, 4 -- High, 5 -- Very High).

The required test environment and code have been delivered. All test cases for each identified product risk item have been written and are ready to be executed. The Database used to contain the Smart Cards is empty and so only new Smart Cards can be used during test execution.

A Smart Card can only be activated if it has been previously pre-activated. This means the postconditions for the execution of the test cases to test the pre-activation of the Smart Card are the pre-conditions for activation of the Smart Card.

Which of the following statements represents the most effective contribution of the stakeholders to the completion of the failure mode analysis table?

K4 3 credits

AThe aircraft pilot and the customer representative should contribute to assess the detection. The chief software engineer, the system architect and the expert tester should contribute to assess the priority.

BThe aircraft pilot and the customer representative should contribute to assess the priority. The chief software engineer, the system architect and the expert tester should contribute to assess the detection.

CThe system architect and the chief software engineer should contribute to assess the priority. The expert tester is the only one who should contribute to assess the detection.

DThe aircraft pilot is the only one qualified to contribute to assess the priority and thus should be assigned this task. The customer representative should contribute to assess the detection.

Answer : B

Question 4

In the next two months some new features will be constantly added to new releases of a project you are working on as Test Manager.

You have identified as one of the main project risks, that the requirements specification will still be incomplete when your team starts the test design and implementation phase.

Some requirements will most likely be completed too late to allow a proper test preparation. You and your test team have already worked on several similar past projects in the same organization.

Which one of the following options would you expect to be the most effective at mitigating this risk?

K4 3 credits

ADon't prepare any test and just run the regression test suite to check that the new features don't introduce regression

BMake reasonable assumptions about the missing details and design lightweight tests that can be easily updated during test execution

CDon't design any test until the test execution starts, then communicate that test execution is blocked due to incomplete requirements

DEven if there are only few details missing, escalate the risk to the project manager without preparing any tests

Answer : B

Question 5

The following are the exit criteria described in the test plan of a software product:

EX1. The test suite for the product must ensure that at least each quality risk item is covered by at least one test case (a quality risk item can be covered by more test cases).

EX2. All test cases in the test suite must be run during the execution phase.

EX3. Defects are classified into two categories: ''C'' (critical defect) and ''NC'' (non-critical defect).

No known C defects shall exist in the product at the end of the test execution phase.

Which of the following information is useless when the specified exit criteria is evaluated? K2 1 credit

AA traceability matrix showing the relationships between the product risk items and the test cases

BA list of all the open defects with the associated classification information extracted from the defect tracking system

CA chart, showing the trend in the lag time from defect reporting to resolution, extracted from the defect tracking system

DThe execution status of all the test cases extracted from the test management tool

Answer : C

Question 6

Which of the following statements describing the consequences of specifying test conditions at a detailed level is NOT true?

K2 1 credit

AIn an environment where the test basis is continuously changing, it is recommended to specify test conditions at a detailed level in order to achieve a better maintainability

BThe specification of test conditions at a detailed level can be effective when no formal requirements or other development work products are available

CThe specification of test conditions at a detailed level can require the implementation of an adequate level of formality across the team

DFor system testing, the specification of test conditions at a detailed level, carried out early in the project as soon as the test basis is established, can contribute to defect prevention

Answer : A

Question 7

Assume you have some data related to confirmation testing during system testing of a past project.

In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three times.

You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 personhours.

Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?

K3 2 credits

A300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

B340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of external failure

C340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure

D300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of detection
