NEW QUESTION # 47
Which of the following defect types is NOT an example of a defect type typically found with API testing?
- A. Loss of transactions
- B. High architectural structural complexity
- C. Data handling issues
- D. Timing problems
Answer: B
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.

You are reviewing the following Java function that determines whether a number input by the user is even or odd:
import java.util.Scanner;
public class OddOrEven {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
System.out.print("Please enter a number: ");
int number = reader.nextInt();
if (number % 2 == 0) {
System.out.println("Your input number '" + number + "' is even.");
} else {
System.out.println("Your input number '" + number + "' is odd.");
}
}
}
You are guided by the following checklist:
*All variables must start with a Capital letter
*All output messages must start with a Capita letter
*There must be a clear comment when explaining the purpose of the dress
How many checklist items Mve been fuelled7
SELECT ONE OPTION
- A. 0
- B. 1
- C. None
- D. 2
Answer: B
Explanation:
Only one of the checklist items has been fulfilled in the Java function provided. Option C is correct.
* Checklist Review:
* Capitalization of Variables: The variable 'Number' does start with a capital letter, fulfilling this checklist item.
* Capitalization of Output Messages: The output messages do not start with a capital letter following the prompt text (e.g., 'your input number...'), failing this checklist item.
* Comment Line: There is no comment line explaining the purpose of the class or method, failing this checklist item.
Thus, only the requirement regarding the capitalization of the variable is met, indicating a partial adherence to the specified coding standards .
NEW QUESTION # 49
Subject to testing is a software system (COTS) for Project Administration and Control (PACS). PACS is a multi-project system for controlling the project time, e.g., in terms of scheduling and tracking, and managing the productivity of projects, e.g., in terms of effort and deliverables.
During various interviews with stakeholders the following information was gathered:
* Using PACS is not business critical. There is no impact such as high financial losses or problems to the operational continuity of an organization. Its application is not critical since the software package does not support directly the operational, or the primary, business processes of an organization. It supports (project) management in the project planning and tracking process. Of course, it will be highly annoying for users if the system "goes down" from time to time. Although this does not have a high impact for the business process as a whole, the Mean Time Between Failures (MTBF) still needs to be at a good level to be successful in the market.
* Users of PACS typically have an academic educational level, but have no prior experience with this particular type of project management software. The system will be used by a large number of users within an organization.
* The system will be used on a regular basis, e.g., several times per day by project managers and several times per week by project employees. This means that the system will not be used very intensively, often only for some data input or an information request. Its usage is not considered to be very time-critical.
* The data is recorded on-line and real-time. The system is expected to run in multiple hardware environments in various network environments. It is also expected that changes in the operational environments will happen in the upcoming period that also need to be supported.
Based on the information provided by the stakeholder, which combination of non-functional quality characteristics should you propose to test as part of your test approach?
- A. Reliability and Performance efficiency
- B. Performance efficiency and Portability
- C. Security and Reliability
- D. Reliability and Portability
Answer: D
Explanation:
Given the stakeholder information provided:
Reliability is important because the system, while not business-critical, still needs a good MTBF to be successful in the market. This is directly mentioned in the stakeholder information.
Portability is essential as the system is expected to run in multiple hardware environments and various network environments, with changes anticipated in the operational environments.
Security is not highlighted as a concern, and performance efficiency, while generally important, is less critical as the system is not used intensively and is not time-critical. Therefore, reliability and portability are the most relevant non-functional quality characteristics to test in this scenario.
NEW QUESTION # 50
Which statement correctly describes continuous testing'
SELECT ONE OPTION
- A. Each modification made to the system is automatically tested and then automatically made implemented in live
- B. Each new build of the system triggers a pre-defined set of tests to be executed automatically.
- C. Each modification made to the system triggers the tests that cover that change to be executed automatically.
- D. Each new build of the system triggers deployment into a testing environment.
Answer: B
Explanation:
The correct description of continuous testing is that each new build of the system triggers a pre-defined set of tests to be executed automatically. This approach ensures that any changes or additions to the system are immediately validated, helping to catch issues early and streamline the development process .
NEW QUESTION # 51
Given the following pseudocode:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?
- A. No unreachable code
- B. Unreachable code at line 17
- C. Unreachable code at line 15
- D. Infinite loop from line 7 to line 13
Answer: B
Explanation:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
Explanation of Control Flow:
* Initialization:
* tax% := 0
* Get Tax Rate:
* GET (tax_rate)
* While Loop:
* Loop runs while tax_rate > 0.
* Inside the loop:
* If tax_rate > 3, set tax_rate to 3.
* Update tax% by adding tax_rate / 10.
* Decrement tax_rate by 1.
* Post-Loop Condition Checks:
* After the loop, check the value of tax%:
* If tax% > 0.6, print "tax rate is high".
* Else if tax% < 0.1, print "tax rate is zero".
* Otherwise, print "tax rate is low".
Unreachable Code Analysis:
* The ELSEIF tax% < 0.1 THEN condition (line 17) is unreachable.
* In the loop, tax% is incremented by a minimum of 0.1 each time tax_rate is greater than 0.
* Therefore, tax% cannot be less than 0.1 after the loop.
Conclusion:
* Line 17 (ELSEIF tax% < 0.1 THEN) will never be true given the logic of the loop.
NEW QUESTION # 52
Which statement about test automation is TRUE?
SELECT ONE OPTION
- A. Minimizing the test suite by selecting, preparing and running only a subset of tests by using risk analysis should always be an objective
- B. Increasing test automation levels will eliminate the need for manual testing during continuous deployment
- C. Increasing test automation levels to increase the frequency of continuous deployment should always be an objective
- D. Increasing test automation levels may decrease the frequency at which continuous deployments to production can be made
Answer: C
Explanation:
The true statement about test automation, particularly in contexts aiming for continuous deployment, is that increasing automation levels is generally pursued to increase deployment frequency. Automated tests can be executed faster and more frequently than manual tests, thereby supporting rapid iterative development and continuous integration practices. This accelerates the overall software development process, allowing for quicker deployments to production .

NEW QUESTION # 54
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 unreachable code.
- B. The Price program contains an infinite loop.
- C. The Price program contains no control flow anomalies.
- D. The Price program contains data flow defects.
Answer: B
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 # 57
Given the following code:
If x > y and z = 3 statement!
elself z = 4
statement2
endif;
What is the minimum number of tests needed to achieve 100% statement coverage?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
To achieve 100% statement coverage, you need to ensure every executable statement in the code is executed at least once during testing. Given the code:
If x > y and z = 3 statement1 elseif z = 4 statement2 endif;
Two tests are required:
* Test 1: Set x > y and z = 3 to execute statement1.
* Test 2: Set z = 4 (irrespective of the condition x > y) to execute statement2.
With these two tests, both conditions that lead to the execution of statement1 and statement2 are covered.
NEW QUESTION # 58
Given the following pseudocode:
Program tax check
BEGIN
yearly := 0
tax := 0
get (monthly)
get (tax_rate)
for I = 1..12 loop
yearly := yearly + monthly
tax := tax - (tax_rate * monthly)
ENDLOOP
salary := monthly * 12
IF salary = yearly THEN
print ("Salary OK")
ELSE
print ("Salary not OK")
ENDIF
year_tax := salary * tax_rate
IF year_tax = tax THEN
print ("Tax Problem")
ENDIF
END tax check
If control flow analysis is performed on the pseudocode, which of the following results is MOST likely?
- A. No unreachable code
- B. Unreachable code at line 19
- C. Unreachable code at lines 15 and 19
- D. Unreachable code at line 15
Answer: B
Explanation:
Control flow analysis is a technique used to examine the sequence in which instructions or statements are executed within a program. In the given pseudocode, the key aspects to consider are the logical flow and any conditional branches that may lead to unreachable code.
The pseudocode provided is:
Program tax check
BEGIN
yearly := 0
tax := 0
get (monthly)
get (tax_rate)
for I = 1..12 loop
yearly := yearly + monthly
tax := tax - (tax_rate * monthly)
ENDLOOP
salary := monthly * 12
IF salary = yearly THEN
print ("Salary OK")
ELSE
print ("Salary not OK")
ENDIF
year_tax := salary * tax_rate
IF year_tax = tax THEN
print ("Tax Problem")
ENDIF
END tax check
Analysis:
* Initialization and Input:yearly and tax are initialized to 0. The program takes monthly and tax_rate as
* input.
* Loop Execution:The loop runs from 1 to 12, accumulating monthly into yearly and adjusting tax accordingly.
* Salary Calculation and Check:After the loop, salary is calculated as monthly * 12. The program then checks if salary is equal to yearly. Given the loop accumulates monthly into yearly 12 times, salary will always equal yearly, making the IF salary = yearly condition always true. Thus, the "Salary OK" message will always be printed, and the ELSE branch will never be executed.
* Yearly Tax Calculation and Check:year_tax is calculated as salary * tax_rate. Then, it checks if year_tax is equal to tax. However, due to the accumulation and subtraction inside the loop, tax would likely not equal year_tax, making the condition IF year_tax = tax false in most practical scenarios.
Therefore, the "Tax Problem" message at line 19 is unlikely to be printed.
Conclusion:
Given this flow, the ELSE block associated with the IF salary = yearly condition (line 15) is unreachable.
However, the critical analysis indicates that the code at line 19, which prints "Tax Problem", is also unreachable due to the logic flow where the condition is rarely true.
Thus, the result is that line 19 is more certainly unreachable.

NEW QUESTION # 61
Which of the following statements is TRUE regarding tools that support component testing and the build process?
- A. Component testing and build automation tools are only used by developers.
- B. Component testing tools are typically specific to the programming language and may be used to automate unit testing.
- C. Build automations tools facilitate manual testing at a low level by allowing the change of variables values during test execution.
- D. Component testing tools are the basis for a continuous integration environment.
Answer: B
Explanation:
Component testing tools, which are often specific to a programming language, are used to automate unit tests (answer C). These tools help to validate the functionality of individual components or units of code in isolation from the rest of the application. While build automation tools are indeed used by developers and are related to continuous integration (answers A and D), and they can facilitate testing at various levels (answer B), component testing tools' primary purpose is to support the testing of individual components, often through automated unit tests, which can be specific to the language in which the components are written.
NEW QUESTION # 62
A major Caribbean bank typically develops their own banking software using an Agile methodology. However, for some specific components COTS software is acquired and used. The bank does not want to create a dependency on any external COTS supplier.
As part of the test approach, portability testing will be performed. Which portability sub-characteristic is especially relevant for the Caribbean bank?
- A. Co-existence
- B. In stall ability
- C. Replaceability
- D. Adaptability
Answer: C
Explanation:
Portability testing is concerned with how well software can be transferred from one environment to another. In the context of a bank using COTS (Commercial Off-The-Shelf) software, the sub-characteristic of replaceability becomes particularly relevant. This is because the bank does not want to create a dependency on any external COTS supplier, meaning it should be able to replace the software with another product without significant effort or operational disruption. Replaceability ensures that if needed, the bank can switch to different software, thereby mitigating the risk of supplier dependency.
NEW QUESTION # 63

Which maintainability sub-characteristic should be covered by the test approach during the initial development?
- A. Analysability
- B. Re-usability
- C. Modularity
- D. Modifiability
Answer: D
Explanation:
In the context of a software company in Spain developing mobile applications with an expectation of many small updates due to changing configurations and customer feedback, focusing on being able to change the software effectively and efficiently during initial development without introducing new defects is crucial. The maintainability sub-characteristic that should be covered by the test approach during the initial development is Modifiability.
Modifiability refers to the ease with which a software product can be modified to correct faults, improve performance or other attributes, or adapt to a changed environment. In a scenario where frequent and small updates are anticipated, ensuring that the software architecture and design support easy modification is vital.
This not only aids in implementing changes more rapidly but also helps in maintaining the stability and integrity of the application, thereby preventing the introduction of new defects. The focus on modifiability ensures that the software remains responsive to customer feedback and evolving requirements without compromising on quality or performance.
