CTAL-TM_SYLL2012 Online Practice Questions and Answers

You are the Test Manager for a project to develop a web customer portal of a Pay-TV company that allows customers (with a smartcard and a set-top box) to purchase digital contents.

In the "select" page the system displays a dialogue where the customer can select the items (digital contents) he/she is interested in. In this page he/she can add one or more items to a shopping cart. An item consists of a product and a

duration.

There are three types of products: Movie, sport and premium (movie and sport).

There are four possible durations: 1 months, 2 months, winter (from the beginning of January to end of March) and summer (from the beginning of July to end of September).

All the combinations of products and durations are allowed to define an item. Thus there are twelve possible items. A maximum of six different items can be added to the shopping cart at a time.

When the customer decides to check out he/she goes to the "purchase" page where he/she can pay the total amount of the shopping cart in three different ways:

-

using a credit voucher

-

using a credit already charged on the smartcard

-

using a credit card (accepted credit cards are. Visa, MasterCard and Great Wall Card)

The customer can logout from both the "select" and "purchase" pages. In this case no purchase is made.

You decide to apply a blended risk-based and reactive testing strategy and the following is a subset of the exit criteria for system testing:

EXCR1- Each "critical" quality risk item must be covered by at least one test condition

EXCR2- Each "critical" requirement must be covered by at least one test condition

You are following a risk-based testing strategy. The test execution time is very limited. Assume that all the product risk items require more or less the same level of test effort.

Which of the following answers describes the best execution schedule in this scenario?

A. 1- Test the acceptance of transactions coming from the IVR channel 2- Test the correct charge of the Smart Card with the required contents 3- Test the correct pre-activation of the Smart Card 4- Test the correct activation of the Smart Card

B. 1- Test the correct pre-activation of the Smart Card 2- Test the correct charge of the Smart Card with the required contents 3- Test the correct activation of the Smart Card 4- Test the acceptance of transactions coming from the IVR channel

C. 1- Test the correct activation of the Smart Card 2- Test the correct pre-activation of the Smart Card 3- Test the correct charge of the Smart Card with the required contents 4- Test the acceptance of transactions coming from the IVR channel

D. 1- Test the correct pre-activation of the Smart Card 2- Test the correct activation of the Smart Card 3- Test the correct charge of the Smart Card with the required contents 4- Test the acceptance of transactions coming from the IVR channel

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 post- conditions 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?

A. The 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.

B. The 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.

C. The 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.

D. The 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.

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?

A. 4

B. 5

C. 6

D. 7

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?

A. Extract 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

B. Automate all functional and non-functional system tests

C. Apply systematic and exploratory testing for integration and system test

D. Perform exploratory testing sessions with adequate charters covering security aspects

You are performing a quality risk analysis for a CSCI (Computer Software Configuration Item) used to implement a CBIT (Continuous Built-In Test) module of a safety-critical system.

During the quality risk analysis you are trying to identify the ways in which failures of the CBIT module can occur, for each of them trying to determine the potential causes and likely effects, and the risk level (calculated as the product of three

factors: severity, occurrence and detection).

Which of the following risk analysis techniques are you working with?

A. A lightweight product risk analysis technique

B. Failure Mode and Effect Analysis

C. Wide Band Delphi

D. Cost of Exposure

You are the Test Manager of a project that adopts a V-model with four formal levels of testinG.

unit, integration, system and acceptance testing.

On this project reviews have been conducted for each development phase prior to testing, which is to say that reviews of requirements, functional specification, high-level design, low-level design and code have been performed prior to

testing.

Assume that no requirements defects have been reported after the release of the product.

Which TWO of the following metrics do you need in order to evaluate the requirements reviews in terms of phase containment effectiveness?

A. Number of defects found during the requirements review

B. Total number of defects attributable to requirements found during unit, integration, system and acceptance testing

C. Total number of defects found during functional specification review, high-level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing

D. Time to conduct the requirements review

E. Total number of defects attributable to requirements, found during functional specification review, high-level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing

Which of the following statements about the STEP test process improvement model is true?

A. In the STEP model, tests validate the requirements and use cases when they are developed

B. The STEP model stresses defect detection and demonstration of capability, whereas the defect prevention is a secondary potential goal of testing

C. The STEP model assures that the system requirements specification and the test design specification processes don't overlap

D. In the STEP model, testware design occurs after coding

Assume you are managing a test automation project for a mission-critical system.

Because vendor provided tools and open source solutions don't meet the needs of this project, you ask your test team to develop a custom automation framework.

Which of the following management issues associated to the development of this custom automation framework is least likely to manage?

A. Proper testing for the custom automation framework must be performed

B. The custom automation framework will require an adequate documentation

C. The changes to the custom automation framework should be communicated to all external users of this tool under the GNU license

D. The custom automation framework will need proper maintenance

After a selection process you have selected a test management tool that is going be introduced in your organization and used by your test team in a pilot project.

You have already identified the member of your test team who will be the administrator of the tool, since he/she has a significant experience with the administration of test management tools and so he/she is able to make effective and efficient

up-front decisions about "how" the tool will be used. You have also developed a training plan for the other members of your test team.

In collaboration with the administrator of the tool you have also devised standard ways of managing, storing and maintaining the tool and its assets including backup/restore procedures.

You have also analyzed standard formats supported by the tool (CSV, XLS, XML, etc.) to export, import and archive all the information managed by the tool itself (requirements, test case specifications, test plans etc.) for compliance with the

most important test management tools, in order to minimize the impacts of migrating this information to a new tool that could replace the existing one in the future.

Which of the following phases in the lifecycle of the new tool has NOT been adequately considered in this description?

A. Acquisition

B. Support and maintenance

C. Evolution

D. Retirement
