Which of the following sets of test data can be used to achieve Modified Condition/Decision Coverage with the least number of tests?
- A. Set 1
- B. Set 4
- C. Set 2
- D. Set 3
Answer: D
Explanation:
For Modified Condition/Decision Coverage (MC/DC), each condition within a decision must independently affect the decision's outcome. The provided sets of values need to be analyzed to ensure that each component of the decision ((A > B) or (C > D) and (E = F)) can independently influence the result of the combined expression. Set 3 includes variations for all variables that allow each condition to be tested both true and false independently while keeping the overall expression's outcome affected. This choice provides the most efficient path to achieving MC/DC with minimal tests.
NEW QUESTION # 54
You are working for a company that has a product in the field that has reached its capacity. The system cannot handle any more users without a significant degradation in performance and a significant spike in resource requirements.

- D. it is an integrated set of tools that will automatically compile, test and deliver into a virtual environment a new build of the product under test
Answer: A
Explanation:
Service virtualization is used in test environments to simulate the behaviors, data, and performance characteristics of dependent systems that are not available for testing due to limitations such as cost, access, or complexity. This allows for more thorough testing of the product under test in a controlled, stable environment that mimics real-world conditions without the need for actual live systems .
NEW QUESTION # 58
At which test level would reliability testing most likely be performed?
- A. Functional acceptance testing
- B. Static testing
- C. System testing
- D. Component testing
Answer: C
Explanation:
Reliability testing is aimed at verifying the software's ability to function under expected conditions for a specified period of time. It is typically conducted during system testing, where the software is tested in its entirety to ensure that all components work together as expected in an environment that closely simulates the production environment. Reliability testing is not typically associated with static testing, component testing, or functional acceptance testing, as these levels of testing do not address the overall behavior of the system over time.
NEW QUESTION # 59
Which of the following is a generic risk factor that should be considered by a Technical Test Analyst during a product risk analysis?
- A. Visibility of failure leading to negative publicity and potential image damage.
- B. Complexity of new technology.
- C. Frequency of use of the affected feature by end-users.
- D. High change rate of business requirements.
Answer: B

A Technical Test Analyst during a product risk analysis would consider the complexity of new technology as a generic risk factor. Complex new technology can introduce uncertainties and potential issues that may not be well-understood, which can increase the risk of defects. Frequency of use, visibility of failure, and high change rate of business requirements are also valid considerations, but they are more specific to particular scenarios or aspects of the product rather than the generic technological complexity which is always a concern regardless of the context.
NEW QUESTION # 60
Consider the following specification:
If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline's frequent flier program. If you don't hold a gold card, there is a possibility that you will get 'bumped' off the flight if it is full when you check in late.
This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy
Test 3: A person who is bumped from the flight
What is the level of decision coverage achieved by these three tests?
- A. 67%
- B. 75%
- C. 60%
- D. 80%
Answer: A
Explanation:
The control flow graph provided illustrates the decision points for an airline's upgrade and boarding process. Decision coverage is a measure of the percentage of decision points executed during testing:
Test 1 covers the decision points: Gold card? (Yes) and Business full? (No).
Test 2 covers: Gold card? (No) and Economy full? (No).
Test 3 covers the decision that leads to being bumped from the flight, which is Economy full? (Yes) and Business full? (Yes).
From the given tests, the decision points for Gold card? (No) and Business full? (No) are not tested, leaving us with 4 out of 6 decision points covered, which is approximately 67% decision coverage.
