NEW QUESTION # 27
Which of the following defect types is NOT an example of a defect type typically found with API testing?
- A. High architectural structural complexity
- B. Data handling issues
- C. Timing problems
- D. Loss of transactions
Answer: A
Explanation:
In the context of API testing, the defect types generally found are related to the specific interactions with the API, such as issues with data formatting, handling, validation, and the sequencing or timing of API calls.
Architectural structural complexity is not typically a defect that would be identified at the API testing level.
API tests are concerned with the interface and immediate integration points, not the overarching system architecture, which would be more relevant to design or system-level testing.
NEW QUESTION # 28
At which test level would performance efficiency testing most likely be performed?
- A. Integration testing
- B. System testing
- C. Component testing
- D. User acceptance testing
Answer: B
Explanation:
Performance efficiency testing is most commonly associated with system testing. This is the level at which the complete, integrated system is evaluated, and it is typically where performance, load, and stress testing are conducted to assess the system's behavior under various conditions and loads. Performance efficiency testing at this level helps to ensure that the system meets the necessary performance criteria as a whole.
NEW QUESTION # 29
You have been assigned to perform a review on code provided below:
Which type of defect should you report as part of the code review?
- A. Endless loop
- B. Unreachable code
- C. Too many nested levels
- D. No defects should be reported, code is correct.
Answer: A
Explanation:
The code provided contains a potential endless loop. The loop is conditioned on the variable 'E' being less than 1 (IF E < 1), but within the loop, there is no operation that modifies the value of 'E'. Therefore, once the loop is entered, if the condition A > B holds true, the value of 'E' remains unchanged, leading to an endless loop situation. The decrement of 'A' in line 15 does not guarantee an exit condition for the loop, as it does not affect the value of 'E'. This is a control flow defect that could cause the program to hang or crash.
NEW QUESTION # 30
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. Likelihood and impact
- B. Financial damage, frequency of use and external visibility
- C. Functionality, reliability, usability, maintainability, efficiency and portability
- D. Severity and priority
Answer: A
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 # 31
Assume you are involved in testing a Health Insurance Calculation system.
At the main screen one can enter information for a new client. The information to be provided consists of last name, first name and date of birth. After confirmation of the information, the system checks the age of the potential new client and calculates a proposed premium.
The system also has the option to request information for an existing client, using the client's ID number.
A keyword-driven automation approach is being used to automate most of the regression testing.
Based on the information provided, which TWO of the options provided would be the MOST LIKELY keywords for this application? (Choose two.)
- A. Exclude_Client
- B. Enter_Client
- C. Remove_Client
- D. Select_Client
- E. Print_Premium
Answer: B,D
Explanation:
Considering the functionalities described for the Health Insurance Calculation system, the keywords would represent the main actions that can be performed in the system. 'Enter_Client' would be a keyword for entering new client information, which is a primary feature of the system as described. 'Select_Client' would be used to retrieve information for an existing client using the client's ID number, which is another main functionality. Other options such as 'Remove_Client', 'Print_Premium', and 'Exclude_Client' are not explicitly mentioned in the provided system functionalities, therefore, 'Enter_Client' and 'Select_Client' are the most likely keywords for automation.
NEW QUESTION # 32
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. (4,5. 0); {5, 4, 5)
- C. (5. 4, 0); (3, 2, 5); (4, 5, 0)
- D. (5. 3, 2); (6, 4, 2); (5, 4, 0)
Answer: D
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.
NEW QUESTION # 33
You are working on project where re-use of software is an objective. You are involved in the project as a Technical Test Analyst and have been given the task to develop a checklist for code reviews.
Which question from the list below should you implement as part of the code review checklist?
- A. Are all modules, data, and interfaces uniquely identified?
- B. Can each item be implemented with the techniques, tools, and resources available?
- C. Is it possible during acceptance testing to verity whether the item has been satisfied?
- D. Are all variables defined with meaningful, consistent and clear names?
Answer: A
Explanation:
For a project where the reuse of software components is a key objective, it is essential to ensure that all modules, data, and interfaces are uniquely identified. This facilitates the tracking, maintenance, and reuse of these components in different parts of the software or in other projects. Unique identification helps in preventing confusion and conflicts that may arise due to the reuse of components that have the same name but different functionalities or interfaces.
NEW QUESTION # 34
Consider the pseudo code for the Price program:
Which of the following statements about the Price program describes a control flow anomaly to be found in the program?
- A. The Price program contains data flow defects.
- B. The Price program contains unreachable code.
- C. The Price program contains an infinite loop.
- D. The Price program contains no control flow anomalies.
Answer: C
Explanation:
The pseudo code provided for the Price program shows a potential for an infinite loop due to the way the
'Del_Charge' variable is being manipulated. The loop is set to continue 'WHILE Del_Charge > 0', and within the loop, 'Del_Charge' is initially set to 5 and then potentially decreased by 2 if 'Sale_Value > 60000'.
However, at the end of each loop iteration, 'Del_Charge' is increased by 1. This means that if 'Sale_Value' is not greater than 60000, 'Del_Charge' will not decrease and will instead increment indefinitely, causing an infinite loop. Even if 'Sale_Value' is greater than 60000, the decrement by 2 could be negated by the subsequent increments if the loop runs enough times, potentially leading to an infinite loop situation. There is no guaranteed exit condition once the loop is entered, which is a control flow anomaly.
NEW QUESTION # 35
Which of the following is a valid reason for including performance testing in a test approach?
- A. To mitigate the risk of long response times to defects reported by users and/or customers.
- B. To evaluate the ability of a system to handle increasing levels of load.
- C. To reduce the threat of code insertion into a web page which may be exercised by subsequent users.
- D. To evaluate the system's tolerance to faults in terms of handling unexpected input values.
Answer: B
Explanation:
Performance testing is a key part of ensuring that a system can handle the expected load and perform well under high demand. This type of testing is designed to test the robustness, speed, scalability, and stability of the system under a given workload. It is not primarily concerned with security threats such as code insertion (Option A), nor with fault tolerance in terms of unexpected input values (Option B), nor with the speed of addressing user-reported defects (Option C), although these may be tangential benefits. Performance testing is focused on ensuring that the system meets performance criteria and can handle increasing loads without degradation of service, which is essential for providing a good user experience and for the system's reliability.

You are working on project where re-use of software is an objective. You are involved in the project as a Technical Test Analyst and have been given the task to develop a checklist for code reviews.
Which question from the list below should you implement as part of the code review checklist?
- A. Are all modules, data, and interfaces uniquely identified?
- B. Can each item be implemented with the techniques, tools, and resources available?
- C. Is it possible during acceptance testing to verity whether the item has been satisfied?
- D. Are all variables defined with meaningful, consistent and clear names?
Answer: A
NEW QUESTION # 37
Consider the code fragment provided below:
The comment frequency of the code fragment is 13%.
To which non-functional quality characteristic does a good level of comment frequency especially contribute?
- A. Portability
- B. Performance Efficiency
- C. Maintainability
- D. Usability
Answer: C
Explanation:
The comment frequency in a code fragment relates to the number of comments in relation to the code size. A good level of comment frequency can significantly contribute to the maintainability of the software.
Maintainability is a non-functional quality characteristic that refers to the ease with which a software system can be modified to correct defects, update features, improve performance or other attributes, or adapt to a changed environment. Comments in the code help developers understand the logic, purpose, and functionality of the code, which is crucial when modifications are required. This does not directly contribute to portability, usability, or performance efficiency, which are concerned with different aspects of the software's operation and user interaction.
NEW QUESTION # 38
Which of the following is a valid reason for including security testing in a test approach?
- A. To provide measurements from which an overall level of availability can be obtained.
- B. There is a threat of unauthorized copying of applications or data.
- C. To evaluate the ability of a system to handle peak loads at or beyond the limits of its anticipated or specified workloads
- D. Software changes will be frequent after it enters production.
Answer: B
Explanation:
Including security testing in a test approach is valid when there are concerns about unauthorized access or activities, such as the threat of unauthorized copying of applications or data (option A). This type of testing aims to uncover vulnerabilities that could be exploited to compromise the confidentiality, integrity, or availability of the system. The other options listed-availability measurements (option B), system's peak load handling (option C), and frequent software changes (option D)-relate to different aspects of testing, such as reliability, performance, and maintainability, which are not directly associated with security testing.
NEW QUESTION # 39
The following characteristics were identified during an early product risk-assessment for a software system:
* the software system needs to manage synchronization between various processes
* microcontrollers will be used that will limit product performance
* the hardware that will be used will make use of timeslots
* the number of tasks supported in parallel by the software system is large and are often highly complex.
Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?
- A. Portability testing
- B. Security testing
- C. Maintainability testing
- D. Time-behaviour testing
Answer: D
Explanation:
The characteristics listed in the question point towards the need to manage synchronization between processes and make efficient use of limited hardware resources, such as microcontrollers and timeslots.
Additionally, the complexity and concurrency of tasks highlight the importance of the software's performance over time. Time-behaviour testing is the most appropriate non-functional test type to perform in this scenario as it focuses on evaluating the timing aspects of the system, such as response times, processing times, and throughput rates. It ensures that the system meets its time-related requirements, which is critical for systems reliant on synchronization and limited by hardware performance constraints.
NEW QUESTION # 40
Which of the following statements BEST describes how tools support model-based testing?
- A. Finite state machines are used to describe the intended execution-time behavior of a software-controlled system.
- B. An engine is provided that allows the user to execute the model.
- C. Large sets of test cases are generated to provide full code coverage.
- D. Random sets of threads of execution are generated as test cases.
Answer: A
Explanation:
Model-based testing tools support the creation and execution of tests based on models of the system under test. Finite state machines (FSMs) are often used in model-based testing to describe the expected behavior of a system during execution. FSMs help in defining the states of the system and the transitions between these states based on events, which can then be used to generate test cases that validate the system's behavior against the model.
NEW QUESTION # 41
Consider the code fragment provided below:
How many test cases are needed for the code fragment lines 26 - 37 to achieve 100% modified condition/decision coverage?
- A. 8 test cases
- B. 4 test cases
- C. 6 test cases
- D. 2 test cases
Answer: B
Explanation:
Modified condition/decision coverage (MC/DC) requires each condition in a decision to be shown to independently affect the decision's outcome. For the code fragment provided, we have three independent conditions that need to be evaluated both as true and false. The minimum number of test cases needed to satisfy MC/DC for three conditions is four, which would allow each condition to be shown to independently affect the outcome of the decision.
NEW QUESTION # 42
A component has been analysed during a risk-assessment and rated as highly critical. Which of the following white-box test techniques provides the highest level of coverage and could therefore be used to test this component?
- A. Modified condition/decision testing
- B. Statement testing
- C. Decision testing
- D. Multiple condition testing
Answer: A
Explanation:
Modified condition/decision testing (MC/DC) provides a higher level of coverage compared to other white-box testing techniques because it requires each condition in a decision to be shown to independently affect that decision's outcome. It is more rigorous than both decision testing (which only requires each decision's possible outcomes to be tested) and statement testing (which requires only each executable statement to be executed). Therefore, for a highly critical component, MC/DC is more appropriate as it ensures a more thorough assessment of the logic in the software component.
NEW QUESTION # 43
You are working on an internet banking project. Your company is offering this product to the financial market. For each new customer, some customization will typically be needed. To make the product successful there is a strong focus during development on a reliable and maintainable architecture. To support architectural reviews, a checklist will be developed. Within the checklist specific sections will be attributed to reliability and maintainability.
Which question from the list below should you include in the maintainability section of the architectural review checklist?
- A. Does the password protection of the system adhere to the latest regulations?
- B. Does the system have user-friendly error messages?
- C. Will the system use n-version programming for critical components?
- D. Will the user interface be implemented independently from the other software modules?
Answer: D
Explanation:
In the context of an internet banking project where reliability and maintainability are emphasized, a key factor for maintainability is the modularity of the system. Implementing the user interface independently from other software modules (answer B) can significantly enhance maintainability. This is because it allows changes to be made to the user interface without impacting the underlying business logic or data access layers, making the system more adaptable to change. This kind of separation of concerns is a recognized best practice in software design for maintainability. The other options (A, C, and D) relate more to reliability and security aspects than to maintainability.
NEW QUESTION # 44
Which of the following does NOT contribute to a more effective review preparation by the Technical Test Analyst?
- A. The usage of review checklists.
- B. Ensure that participants spend enough time during preparation, e.g.. by managing checking rate (number of pages checked per hour during review preparation).
- C. Managing logging rate (number of defects logged per minute during the meeting).
- D. Review training for the Technical Test Analyst.
Answer: C
Explanation:
An effective review preparation by a Technical Test Analyst includes ensuring that participants are well-prepared and that they spend enough time on preparation, which can be managed by checking the rate (option A). The use of review checklists (option C) and providing review training (option D) are also methods that contribute to more effective review preparation. However, managing the logging rate (option B), or the number of defects logged per minute during the meeting, is not related to the preparation phase but rather to the defect detection and logging phase during the actual review meeting. It is not a preparation activity but a review execution activity.
NEW QUESTION # 45
Consider the pseudo code provided below:
Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5
- A. A=7, B=9, Expected output: 7
- B. A=6, B=12, Expected output: Bingo!
- C. No additional test cases are needed to achieve 100% statement coverage.
- D. A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
Answer: C
Explanation:
100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:
Test 1 executes the MIN = B statement when A and B are equal.
Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.
All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.
