ISTQB-ATM Practice Questions

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

You are the Test Manager on a project following an iterative life-cycle model. The project should consist of nine iterations of one month duration each. It is planned to develop the most important features to have a stable core of the application in the first three iterations and to add the additional features in the last six iterations. At the beginning of the first iteration, only a draft version of the requirements specification document for the core features is available. Assume that during each of the first three iterations, the chosen features are fully completed and unit tested. Which of the following statements is true in this context? K4 3 credits

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

You are the Test Manager of a new project aimed at developing a software system that must be certified at level B of the DO-178B standard. The project will follow a V-Model software development life cycle and it will have four formal levels of testing: component, integration, system and acceptance testing. You must produce the test plan documentation for this project by providing an adequate coordination across the four levels of testing in order to assure audit ability. Which of the following answers would you expect to best describe how to organize the test plan? K3 2 credits

The main objectives the senior management team wants to achieve are: - to reduce the costs associated with dynamic testing - to use reviews to ensure that the project is on course for success and following the plan - to use reviews as a well-documented and effective bug-removal activity following a formal process with well-defined roles - to determine the effectiveness of reviews in terms of phase containment - to improve phase containment effectiveness Which of the following answers would you expect to describe the best way to achieve these objectives? K4 3 credits

Assume that the following test cases have been executed at the end of the first week of test execution: TC-001, TC-002 and TC-007. All these tests are ‘passes’. What is the MINIMUM number of the remaining test cases that must be successfully executed to fulfill the EX1 exit criteria? K3 2 credits

During the system testing phase a tester from your test team observes a failure in the system under test and he/she decides to create an incident report. The incident report is currently in a “new” state, indicating it needs to be investigated. Which THREE of the following information items can’t yet be present in the incident report? K3 2 credits (2 credits out of 3 credits correct, 1 credit point)

You are working on a project to develop an authentication system for an e-commerce website. This system provides two features: Registration and authentication. Two different development teams develop these two features. There is a high likelihood that the delivery of the authentication feature to the test team will be three weeks later. To complete the registration the user must provide the following registration inputs: Name, surname, birth date, fiscal code and he/she can select a username and a password. A registered user can be a special user or a normal user. To be identified as a special user, he/she must also provide, during the registration process, a voucher possibly received from the IT department. Access is granted only if a user is registered and the password is correct: In all other cases access is denied. If the registered user is a special user and the password is wrong, a special warning is shown on the system console. You are currently performing a quality risk analysis using FMEA . Based only on the given information, which of the following is NOT a product risk that could be identified during the quality risk analysis? K4 3 credits

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
