You are managing the system testing for a SOA based system. The integrated system consists of several subsystems:
- A SOA middleware
- A CRM (Customer Relationship Management) system
- A BRM (Billing and Revenue Management) system
- A SMS (Subscriber Management System) system and you performed a risk analysis based on these subsystems.
At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue:

In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04.
Which of the following subsystems, based on the risk scores of the table, is most risky?

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?

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?

Which one of the following metrics to be produced needs traceability between the test cases and each item in a proper test basis?
