NEW QUESTION # 268
Which ONE of the following options is aPRODUCT riskand NOT aPROJECT risk?
Answer: B
Explanation:
Product risksare risks thatimpact the quality or functionality of the software, whereasproject risksaffect theprocess, resources, or timeline.
* (A) is correctbecause incorrect calculations impact software correctness.
* (B), (C), and (D) are project risksas they relate toteam coordination, staffing, and schedulingrather than software defects.
Identifyingproduct risksearlyimproves defect detection and ensures better coverage for high-risk areas.
NEW QUESTION # 269
Which of the following applications will be the MOST suitable for testing by Use Cases
Answer: A
Explanation:
A new navigation system compared with a previous system is the most suitable application for testing by use cases, because it involves a high level of interaction between the user and the system, and the expected behavior and outcomes of the system are based on the user's needs and goals. Use cases can help to specify the functional requirements of the new navigation system, such as the ability to enter a destination, select a route, follow the directions, receive alerts, etc. Use cases can also help to compare the accuracy and usability of the new system with the previous system, by defining the success and failure scenarios, the preconditions and postconditions, and the alternative flows of each use case. Use cases can also help to design and execute test cases that cover the main and exceptional paths of each use case, and to verify the satisfaction of the user's expectations.
The other options are not the most suitable applications for testing by use cases, because they do not involve a high level of interaction between the user and the system, or the expected behavior and outcomes of the system are not based on the user's needs and goals. A billing system used to calculate monthly charge based on a large number of subscriber parameters is more suitable for testing by data-driven testing, which is a technique for testing the functionality and performance of a system or component by using a large set of input and output data. The ability of an antivirus package to detect and quarantine a new threat is more suitable for testing by exploratory testing, which is a technique for testing the functionality and security of a system or component by using an informal and flexible approach, based on the tester's experience and intuition. The suitability and performance of a multimedia (audio video based) system to a new operating system is more suitable for testing by compatibility testing, which is a technique for testing the functionality and performance of a system or component by using different hardware, software, or network environments.

NEW QUESTION # 270
Following a risk-based testing approach you have designed 10 tests to cover a product risk with a high-risk level. You want to estimate, adopting the three-point test estimation technique, the test effort required to reduce the risk level to zero by executing those 10 tests. You made the following three initial estimates:
* most optimistic = 6 person hours
* most likely = 30 person hours
* most pessimistic = 54 person hours
Based only on the given information, which of the following answers about the three-point test estimation technique applied to this problem is true?
Answer: A
Explanation:
Explanation
The three-point test estimation technique is a method of estimating the test effort based on three initial estimates: the most optimistic, the most likely, and the most pessimistic. The technique uses a weighted average of these three estimates to calculate the final estimate, which is also known as the expected value. The formula for the expected value is:
Expected value = (most optimistic + 4 * most likely + most pessimistic) / 6 Using the given values, the expected value is:
Expected value = (6 + 4 * 30 + 54) / 6 Expected value = 30 person hours However, the expected value is not the only factor to consider when estimating the test effort. The technique also calculates the standard deviation, which is a measure of the variability or uncertainty of the estimates. The formula for the standard deviation is:
Standard deviation = (most pessimistic - most optimistic) / 6
Using the given values, the standard deviation is:
Standard deviation = (54 - 6) / 6 Standard deviation = 8 person hours
The standard deviation can be used to determine a range of possible values for the test effort, based on a certain level of confidence. For example, using a 68% confidence level, the range is:
Expected value ± standard deviation
Using the calculated values, the range is:
30±8 person hours
Therefore, the final estimate is between 22 person hours and 38 person hours, which is option A.

NEW QUESTION # 271
Which of the following is a task the Author is responsible for, as part of a typical formal review?
Answer: D
Explanation:
This answer is correct because identifying potential anomalies in the work product under review is one of the tasks the Author is responsible for, as part of a typical formal review. The Author is the person who creates the work product to be reviewed, such as a requirement specification, a design document, or a test case. The Author's tasks include preparing the work product for the review, identifying potential anomalies in the work product, and fixing the anomalies found in the work product after the review.

NEW QUESTION # 272
Your organization's test strategy states that it is desirable to usemore than one method for estimating test effort. You are responsible for estimating test effort for the next project. Based on historical data, the development-to-test effort ratiois5:3.
The initial estimate for thedevelopment effort is 450 person-days.
Which ONE of the following options corresponds to the estimatedtest effortusing the ratio-based method?
Answer: A
Explanation:
Theratio-based estimation methodrelies on historical relationships betweendevelopment and testing effort.
Using the given5:3 ratio:
Thus, the correct answer is270 person-days (D).
* (A) and (C) are incorrectas they overestimate the effort.
* (B) underestimates the testing effort based on the ratio.
Ratio-based estimationhelps allocate resources effectively based on past project data.
