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
Answer : B

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?

Answer : B
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? K3 3 credits
Answer : D
Consider the following skills assessment spreadsheet for your test team (consisting of four team members):
This spreadsheet has three sections: technical expertise, testing skills and professionalism.
The skill levels for each skill area for both the ''technical expertise'' and ''testing skills'' sections have been rated on a four-point scale:
- E (Expert): indicates that a person has expert knowledge and experience in the skill area
- B (Beginner): indicates that a person has some knowledge and experience in the skill area but he/she is not autonomous
- W (Wants to learn): indicates that a person has no knowledge or experience in the skill area but he/she wants to learn that skill
- NI (Not Interested): indicates that a person has no knowledge or experience in the skill area and he/she is not interested to learn that skill
The skill levels for each skill area of the ''professionalism'' section have been rated on a three point scale (H=High, M=Medium, L=Low).
You are using this skills assessment spreadsheet in order to define a training development plan for your test team.
Your objective is to fill the skill gaps by having at least a team member rated as an expert for each skill identified for the ''technical expertise'' and ''testing skills'' sections, and with the ability to train the other team members.
Considering the budget constraints you can send only one person to a training course.
Based only on the given information, which of the following answers would you expect to be the best option to achieve your objective?

Answer : B
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?

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? K2 1 credit
