The following are the requirements identified as ''critical'':
REQ-SEL-001. The user shall be able to combine all the three products with all the four durations to define an item to purchase
REQ-SEL-002. The user shall be able to add a maximum of six different items to the shopping cart REQ-PUR-001. The user shall be able to purchase all the items in the shopping cart using a credit voucher
REQ-PUR-002. The user shall be able to purchase all the items in the shopping cart using the available credit already charged on the smartcard
REQ-PUR-003. The user shall be able to purchase all the items in the shopping cart using all the accepted credit cards (Visa, MasterCard and Great Wall Card)
REG-LOGO-001. The user shall be able to logout (by clicking the logout button) from both the ''select'' and ''purchase'' pages going back to the ''browse'' page (anonymous navigation)
Moreover the following quality risk item has been identified as ''critical'':
QR-P1. The web customer portal might not be able to provide the expected response time (less than 10 sec) for the purchase transactions under a load of up-to 1000 concurrent users Test analysis for system testing has just begun and the following test conditions have been identified.
TC-SEL-01. Test the combinations of products and durations to define an item to purchase TC-SEL-02. Test the maximum number of items, which can be added to the shopping cart
TC-PUR-01. Test the purchase of an item
TC-PUR-02. Test the purchase of an item with the credit charged on the smartcard
What is the MINIMUM number of test conditions that must be added to fulfill both the EXCR1 and EXCR2 exit criteria?

K2 1 credit
Consider the following test strategies:
Consultative test strategy
Reactive test strategy
Analytical test strategy
Process-compliant test strategy
Consider also the following examples of test activities:
1. Prioritize the test cases, based on the results of a FMEA analysis, to ensure early coverage of the most important areas and discovery of the most important defects during test execution
2. Execute usability testing driven by the guidance of a sample of users (external to the test team)
3. Perform exploratory testing sessions throughout the system test phase
4. On an Agile project, execute tests that cover the test conditions identified for each user story of a feature planned for an iteration
Which of the following correctly matches each test strategy with an appropriate example?

In the test strategy document your organization declares:
- To adopt a V-model development lifecycle, with three formal levels of testing. unit, integration and system testing
- To use a blended risk-based and regression-averse testing strategy for each level of testing The following is an excerpt of the ''approach'' section for the system test plan document of a new project:
''Testing will only use manual tests. Due to the short period of time for test execution, the following activities will be performed in parallel with test execution: Test planning, test analysis and test design.
Basic metrics will be taken for test effort (i.e. person-hours), test cases executed (passed/failed), and incidents (no more metrics, such as code coverage, will be collected).'' In the system test plan, no deviations from the test strategy are described. Based only on the given information, which of the following statements is true?

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
