NEW QUESTION # 78
Consider the following control flow graph:
The control flow represents a software component of a car navigation system. Within the project the maximum cyclomatic complexity to be allowed is set at 5.
Which of the following statements is correct?
- A. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 5.
- B. A defect needs to be reported since the cyclomatic complexity of the component is calculated at 6.
- C. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 3.
- D. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 4
Answer: B
Explanation:
Cyclomatic complexity is a measure of the number of linearly-independent paths through a program's source code, which is often used as a measure of the complexity of a program. The control flow graph provided represents the logic of a software component and has more than 5 nodes with decision points, indicating that the complexity would exceed the maximum allowed value of 5. The calculation for cyclomatic complexity is V(G) = E - N + 2P, where E is the number of edges, N is the number of nodes, and P is the number of connected components. In this case, the calculated cyclomatic complexity exceeds the allowed threshold, thus a defect should be reported.

NEW QUESTION # 80
The following user story has been written:
As a paying hotel guest
I want to see the charges that have been added to my bill
So that I can monitor my expenditure and know In advance how much I will have to pay when I check out The notes that have been added to It mention that It must be possible for the guest to get a printout of the bill, see It In a variety of currencies and set a flag in the hotel's billing system against any Item that they wish to challenge.
The following acceptance criteria have been defined:
1.The user shall be able to choose from the most commonly-used currencies.
2.The application must be accessible on most mobile platforms as well as on the hotel room's smart TV.
3.The hotel manager must be notified whenever a bill item is flagged by a hotel guest.
4.End-to-end response time for any individual request submitted by a user must not exceed 7 seconds.
Applying the INVEST technique to this user story, including its acceptance criteria, which of the following statements is correct?
SELECT ONE OPTION
- A. The Negotiable and Small criteria of INVEST have not been satisfied
- B. The INVEST criteria have all been satisfied by this epic
- C. The Testable and Negotiable criteria of INVEST have not been satisfied
- D. The Testable and Small criteria of INVEST have not been satisfied
Answer: D
Explanation:
According to the INVEST criteria, the Testable and Small criteria have not been satisfied for the user story provided. Option B is correct.
* INVEST Criteria: The INVEST model stipulates that user stories should be Independent, Negotiable, Valuable, Estimable, Small, and Testable.
* Analysis of the User Story: The scope of the user story and its acceptance criteria suggests it is too broad (thus not 'Small') and the details provided, especially regarding response times and system notifications, imply potential challenges in effectively testing the story (thus possibly not 'Testable') without further refinement or breaking down the story into smaller, more manageable pieces.
The size and complexity of the requirements indicate that the story might be better classified as an epic, needing decomposition into smaller, more specific user stories that can be more feasibly addressed within agile iterations .
NEW QUESTION # 81
Below is the pseudo-code for the bingo program:
The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?
- A. Variable "AB is defined but subsequently not used.
- B. The hard-coded value '2" should not be used.
- C. An invalid value is assigned to variable "B".
- D. Variable "MIN" is not assigned a value before using it.
Answer: D
Explanation:
In the provided pseudo-code for the Bingo program, the variable MIN is used in the statement MIN = MIN + A without being initialized with a value beforehand. This represents a classic 'use before define' anomaly, as the variable MIN must have an initial value before any operation like addition can be performed on it.
NEW QUESTION # 82
Which of the following statements about performance testing tools is NOT correct?
- A. Significant factors to consider in the implementation of performance testing tools include the flexibility of the tool to allow different operational profiles to be easily implemented, and the hardware and network bandwidth required to generate the load.
- B. Performance testing tools generate a load by simulating a large number of virtual users following their designated operational profiles to generate specific volumes of input data.
- C. Performance testing tools typically drive the application by simulating user interaction at the graphical user interface level to more accurately measure response times.
- D. Typical metrics and reports provided by performance testing tools include the number of simulated users throughout the test, and the number and type of transactions generated by the simulated users, and the arrival rate of the transactions.
Answer: C
Explanation:
The statement about performance testing tools that is NOT correct is that they typically drive the application by simulating user interaction at the graphical user interface (GUI) level to more accurately measure response times. In practice, performance testing tools often simulate user interactions at a protocol or service level rather than the GUI level. This approach allows the tools to generate a high load by simulating many virtual users, which would be challenging to achieve with GUI-level interactions due to the higher resource consumption and slower execution speed associated with GUI automation.
Performance testing tools are designed to assess the performance of a system under a particular load and are not primarily focused on the user interface. They simulate multiple users accessing the system simultaneously, which helps in identifying bottlenecks, understanding the system's behavior under load, and determining how the system scales with increasing load. The tools typically simulate user requests to the server, bypassing the GUI to directly test the backend, APIs, or other service endpoints. This method allows for more efficient and scalable testing, enabling the simulation of thousands of users without the overhead of rendering the GUI.
NEW QUESTION # 83
How many independent paths are shown in the control flow diagram below?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Upon analyzing the control flow diagram provided, there are four distinct paths through the program, considering the flow between decision points and actions. Each path represents a unique sequence of execution through the system logic, dictated by the decision outcomes at various points. This information is critical for ensuring comprehensive testing coverage, as each path may expose different behaviors or outcomes in the application.
NEW QUESTION # 84
You are an experienced tester on an Agile team that is producing a new application. The product backlog has been refined sufficiently to begin development for the first release. This stories in this backlog contain a mixture of functional and non-functional requirements, as well as some technical stories that will provide elements of the application's infrastructure The developers have decided to use TDD as a deveiopment approach but automation of the acceptance tests is not yet planned.
You have been asked to recommend whether or not the team should take an atdd approach as well as TDD.
what would be the BEST recommendation in these circumstances?
SELECT ONE OPTION
- A. YES. use ATTD for all requirements including non-functional and technical stories.
- B. NO. do not use atdd. because it is not compatible with the developers' TDD approach.
- C. YES. use attd, but for the functional requirements only because it cannot be applied to non-functional or technical requirements.
- D. NO. do not use ATDD, because it will not work when the acceptance tests are not automated
Answer: A
Explanation:
Acceptance Test-Driven Development (ATDD) enhances both functional and non-functional aspects of the project, providing a collaborative approach to acceptance criteria that developers, testers, and stakeholders agree upon before development begins. Using ATDD alongside TDD (Test-Driven Development) ensures that both the internal system logic and the user-facing features adhere to the specified requirements, thereby increasing the likelihood of delivering a quality product that meets all stakeholders' expectations .
NEW QUESTION # 85
As a technical test analyst, you are involved in a risk analysis session using the Failure Mode and Effect Analysis technique. You are calculating risk priorities. Which of the following are the major factors in this exercise?
- A. Functionality, reliability, usability, maintainability, efficiency and portability
- B. Likelihood and impact
- C. Severity and priority
- D. Financial damage, frequency of use and external visibility
Answer: B
Explanation:
Failure Mode and Effect Analysis (FMEA) is a structured approach to identify and address potential failures in a system, product, process, or service. The major factors involved in calculating risk priorities in FMEA are typically the severity of the potential failure, its likelihood of occurrence, and the ability to detect it. These factors are usually combined to form a Risk Priority Number (RPN) for each potential failure mode identified.
However, the specific factors mentioned in the options like functionality, reliability, usability, maintainability, efficiency, and portability are quality characteristics that could be considered in an FMEA analysis but are not directly used for calculating risk priorities. Likewise, financial damage, frequency of use, and external visibility might influence the severity or impact of a failure, but they are not standard factors in calculating risk priorities in the context of FMEA. Therefore, the most relevant factors for calculating risk priorities in an FMEA context would typically be the likelihood of the failure occurring and its potential impact, which aligns with option C: Likelihood and impact.
It's important to note that while these explanations are based on general principles and practices related to fault seeding and FMEA, the specifics might vary slightly in different contexts or with different methodologies.
NEW QUESTION # 86
Which of the following is a reason for the Technical Test Analyst to take the time to prepare for a code review?
- A. Allows time to plan the design and implementation of the item being reviewed
- B. Allows time to gather the test metrics for management review
- C. Allows the reviewer time to consider the Interaction of the item being reviewed with other items In the system
- D. Allows time to prepare the test data
Answer: C
Explanation:
Preparing for a code review is essential for understanding how the specific item under review interacts with other system components. This preparation allows the reviewer to identify potential integration issues or dependencies that could affect system functionality or performance. Adequate preparation ensures that the review is thorough and considers the broader system context, which is critical for ensuring that the system operates cohesively and according to specifications.
NEW QUESTION # 87
A unit test should be isolated Which option correctly describes the meaning of 'isolated' as a characteristic of a unit test?
SELECT ONE OPTION
Whenever it is run under the same conditions, it should produce the same results.
- A. It should test only the code for which it was originally written
- B. it should provide immediate feedback.
- C. It should only test the functionality related to it.
Answer: A
Explanation:
The term 'isolated' as a characteristic of a unit test means that it should test only the code for which it was originally written. This ensures that the unit test is focused, minimizes dependencies on other parts of the codebase, and errors can be traced back to specific units without ambiguity .
NEW QUESTION # 88
In what circumstances should you use a simulator instead of an emulator when testing a mobile application?
- A. When a model of the runtime environment Is sufficient for testing
- B. When the hardware device and the runtime environment must be modeled
- C. When security is not a consideration
- D. When there is a need to assess the usability of the application
Answer: A
Explanation:
Simulators and emulators are tools used for testing mobile applications under different conditions. A simulator mimics the software environment but does not emulate hardware. Thus, it is suitable when the test objectives are focused on the application's internal behavior within the context of the software environment, not requiring an exact replica of the hardware conditions. This makes simulators particularly useful for scenarios where the primary concern is how the application runs in the software environment, rather than how it interacts with the underlying hardware.
NEW QUESTION # 89
How many test cases need to be designed to achieve 100% decision coverage in the following piece of pseudo-code which applies discount rates to hotel room bookings?
Read (Loyalty_level)
Read (Room_price)
IF (Room_price > 200)
IF (Loyalty_level = Platinum)
Discount_factor = 80%
ELSE
IF (Loyalty_level = Gold)
Discount_factor = 85%
ELSE
Discount_factor = 95%
ENDIF
ENDIF
ELSE
IF (Room_price > 150)
IF (Loyalty_level = Platinum)
Discount_factor = 85%
ELSE
Discount_factor = 95%
ENDIF
ELSE
Discount_factor = 100%
ENDIF
ENDIF
Room_price = Room_price * Discount_factor
IF (Discount_factor < 100%)
Show message "Congratulations - you have received a discount!"
ENDIF
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
To achieve 100% decision coverage, we need to ensure that every decision (if statement) in the code has been tested for both true and false outcomes. Let's analyze the code and count the decisions:
* IF (Room_price > 200)
* IF (Loyalty_level = Platinum) inside Room_price > 200
* ELSE within the same decision above
* IF (Loyalty_level = Gold) inside the ELSE of decision 2
* IF (Room_price > 150)
* IF (Loyalty_level = Platinum) inside Room_price > 150
* ELSE within the same decision above
* IF (Discount_factor < 100%)
To cover all these decisions, we need test cases for each possible combination:
* Room_price > 200 and Loyalty_level = Platinum.
* Room_price > 200 and Loyalty_level = Gold.
* Room_price > 200 and Loyalty_level not Platinum or Gold.
* Room_price <= 200 and Room_price > 150, and Loyalty_level = Platinum.
* Room_price <= 200 and Room_price > 150, and Loyalty_level not Platinum.
* Room_price <= 150.
From these scenarios, we can see that the minimum number of test cases required to achieve 100% decision coverage is four:
* Test with Room_price > 200 and Loyalty_level = Platinum (tests decision 1 true, 2 true, and 8 true).
* Test with Room_price > 200 and Loyalty_level = Gold (tests decision 1 true, 2 false, 4 true, and 8 true).
* Test with Room_price > 200 and Loyalty_level not Platinum or Gold (tests decision 1 true, 2 false, 4 false, and 8 true).
* Test with Room_price <= 200 and Room_price > 150, and Loyalty_level = Platinum (tests decision 1 false, 5 true, 6 true, and 8 true).
* Test with Room_price <= 200 and Room_price > 150, and Loyalty_level not Platinum (tests decision 1 false, 5 true, 6 false, and 8 true).
* Test with Room_price <= 150 (tests decision 1 false, 5 false, and 8 false).
Given that these six cases test all branches, four test cases are required to ensure that all decisions are covered at least once.
Therefore, the correct answer is A. 4.

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 2
- B. Set 4
- C. Set 1
- 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 # 91
You are asked to provide a practical and pragmatic testing solution for a commercial system where the main user interface is via the Internet. It is critical that the company's existing good name and market profile are not damaged in any way. Time to market is not a critical issue when appropriate testing solutions are identified to mitigate business risks.
A product risk assessment has revealed the following product risk:
* Abnormal application termination due to connection failure of the main interface.
Which of the following is the appropriate test type to address this risk?
- A. Reliability testing
- B. Portability testing
- C. Operability testing
- D. Performance efficiency testing
Answer: A
Explanation:
Reliability testing is the process of checking whether the software consistently performs according to its specifications. For a commercial system with a critical internet-based user interface, ensuring that the application can handle connection failures without abnormal terminations is essential. Reliability testing would include testing the system's ability to recover from failures and continue operating, which directly addresses the risk identified.
NEW QUESTION # 92
You are a Technical Test Analyst preparing load test scripts. You have been invited to a technical review of the system's operational profile document produced by the business. The meeting is next week, during your preparation you notice that volumetric data covering projected transaction volumes will be held in a separate document that will not be available before the meeting. What would be the BEST course of action?
- A. Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers
- B. To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting
- C. Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting
- D. State that you are not a mandatory reviewer but request that both documents be sent to you once agreed
Answer: B
Explanation:
Analysis:
When faced with incomplete documentation during test preparation, it is important to balance the need for thoroughness with the need to maintain project schedules.
B: To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting:
* This option ensures that the review proceeds as planned, preventing project delays. By raising the issue during the meeting, you can highlight the importance of the missing volumetric data and ensure it is addressed promptly.
Explanation of Incorrect Options:
* A: Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers:
* Delaying the meeting might cause project delays and may not be necessary if the issue can be addressed in the meeting.
* C: State that you are not a mandatory reviewer but request that both documents be sent to you once agreed:
* This might cause you to miss important discussions in the review meeting.
* D: Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting:
* This could still result in delays and does not ensure that all necessary information is reviewed in a timely manner.

NEW QUESTION # 93
Consider the pseudo code provided below:
Which of the following options provides a set of test cases that achieves 100% decision coverage for this code fragment, with the minimum number of test cases?
Assume that in the options, each of the three numbers in parenthesis represent the inputs for a test case, where the first number represents variable "a", the second number represents variable "b", and the third number represents variable "c".
- A. (5. 3,2)
- B. (5. 4, 0); (3, 2, 5); (4, 5, 0)
- C. (5. 3, 2); (6, 4, 2); (5, 4, 0)
- D. (4,5. 0); {5, 4, 5)
Answer: C
Explanation:
To achieve 100% decision coverage with the minimum number of test cases, we need to ensure that every branch of the decision is taken at least once. For the code provided:
* The first condition (a>b) is true for the first two test cases and false for the third.
* The second condition (b>c) is true for the first test case, false for the second, and does not matter for the third since the first condition is false.
Therefore, with these three test cases, we cover all possible outcomes of the decision, ensuring 100% decision coverage.
