NEW QUESTION # 39
A project to replace your company's sales and merchandising system has begun. The old system is still in production but is poorly documented and expensive to maintain: changing it has often produced a large quantity of defects. The new version will be developed using modern techniques and technology.
Requirements include:
* Loading sales data, sent electronically from the stores each evening, into a central database where it is then available for other applications.
* Producing sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Predictions of future demand for each product, based on a combination of sales history and forecasting parameters.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant changes.
Requirement 3 is new: these forecasting reports will be run overnight, and users will request them by entering simple parameters online during the day.
The sales data are loaded in an overnight batch run. There have been problems at peak periods when this run has taken longer than scheduled, so that dependent jobs could not finish before the start of the working day.
As a Technical Test Analyst, you have been asked to contribute to the project's Master Test Plan. The key stakeholders are:
* The Merchandising Manager, who wants parameter entry to be quick and easy.
* The Data Centre Manager, who requires the new batch jobs to take less time than the old ones.
No specific performance requirements have been given, either for the batch jobs or for online parameter entry.
Which TWO of the following will BEST meet the objectives of the stakeholders?
- A. Conduct performance testing on the data load and report creation, in parallel with functional system testing.
- B. Conduct performance testing on the forecasting report parameter data entry features, in parallel with functional system testing.
- C. Agree acceptance criteria for modifiability, modularity, and reusability, and measure these for change requests implemented after development begins.
- D. Agree acceptance criteria for performance of the data load and report creation, based on a quantified improvement over the current system.
- E. Agree acceptance criteria for performance of the forecasting report parameter data entry features, based on operational profile models.
Answer: A,B
Explanation:
In this scenario, the key stakeholders have expressed concerns related to performance, specifically in terms of the batch jobs and the ease of parameter entry for forecasting reports. Given these requirements, performance testing is essential to meet their objectives.
Objectives of the Stakeholders:
* Merchandising Manager: Wants parameter entry to be quick and easy.
* Data Centre Manager: Requires the new batch jobs to take less time than the old ones.
Best Testing Approaches:
* Performance Testing on Forecasting Report Parameter Data Entry Features (Option A):
* Conducting performance testing on the parameter data entry features ensures that the process is quick and efficient, meeting the Merchandising Manager's requirement for ease of use.
* Performance Testing on Data Load and Report Creation (Option B):
* Conducting performance testing on data load and report creation will address the Data Centre Manager's concern by ensuring that the batch jobs complete in less time compared to the old system.
Explanation of Incorrect Options:
* C. Agreeing acceptance criteria for modifiability, modularity, and reusability: These criteria are more related to code quality and maintainability rather than performance, which is not the primary concern of the stakeholders.
* D. Agreeing acceptance criteria for performance based on quantified improvement: While this is important, it's not a testing activity itself but rather a prerequisite to performance testing.
* E. Agreeing acceptance criteria based on operational profile models: This is also more related to planning and less about direct testing activities.

NEW QUESTION # 40
Given the following code:
If x > y and z = 3 statement!
elseif z = 4 statement
endif;
What is the minimum number of tests needed to achieve 100% decision coverage?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
To achieve 100% decision coverage, you must ensure every decision in the code has been evaluated both to true and false. Given the code:
If x > y and z = 3 statement1 elseif z = 4 statement2 endif;
Two tests are required:
* Test 1: Set x > y true and z = 3 to evaluate the first decision as true and execute statement1.
* Test 2: Set z = 4 (ensuring the first condition x > y and z = 3 evaluates to false) to evaluate the elseif condition as true and execute statement2.
This testing ensures that both branches of the decision have been evaluated.
NEW QUESTION # 41

NEW QUESTION # 43
Which TWO of the following are generic PRODUCT risk factors that should be considered by a Technical Test Analyst?
a)A high number of performance efficiency defects in the software
b)Inaccurate arithmetic calculations in key business areas cj Particularly complex code d) Communication issues with geographically distributed teams e) Usability-' issues with the design of the user interface
- A. a and c
- B. a and b
- C. b and d
- D. c and e
Answer: A
Explanation:
The question asks for generic product risk factors that should be considered by a Technical Test Analyst. Here are the detailed reasons for each of the options:
* a) A high number of performance efficiency defects in the software: This is indeed a significant product risk. Performance efficiency defects can severely affect the user experience and the overall performance of the system, making it a crucial factor for technical test analysts to consider.
* b) Inaccurate arithmetic calculations in key business areas: While this is critical, it is more of a functional risk specific to the business domain rather than a generic product risk. It concerns the accuracy of the system's operations rather than its overall quality attributes.
* c) Particularly complex code: Complex code is a generic product risk factor because it can lead to increased chances of defects, difficulties in maintenance, and challenges in achieving good test coverage. Complex code often requires more rigorous testing to ensure reliability.
* d) Communication issues with geographically distributed teams: This is a project risk rather than a product risk. While it can affect the testing process and coordination, it does not directly relate to the inherent risks in the product itself.
* e) Usability issues with the design of the user interface: Usability issues are indeed significant but are more specific to the user experience aspect rather than being a broad product risk factor.
From the analysis, the generic product risk factors that stand out are "a high number of performance efficiency defects" and "particularly complex code," making the correct answer B. a and c.
This answer is validated by referring to the ISTQB CTAL-TTA syllabus and sample exam answers, which emphasize the importance of performance efficiency defects and code complexity as key product risk factors.
NEW QUESTION # 44
The last release of a hotel booking website resulted in poor system performance when hotel searches reached peak volumes. To address these problems in the forthcoming release, changes to the system architecture are to be implemented as follows:
Change 1 - Provision of a single Internet service using multiple servers, rather than a single server, to maximize throughput and minimize response time during peak volumes Change 2 - Prevention of unnecessary database calls for objects that were not immediately needed by the calling applications. Achieved by not automatically creating database connections at the start of processing, instead only just before the data is required.
The system architecture document has been drafted and as Technical Test Analyst you have been invited to participate in its review. Which of the following review checklist items is MOST likely to identify any defects in the proposed system architecture for Change 1?
- A. Connection pooling
- B. Caching
- C. Distributed processing
- D. Load balancing
Answer: D
Explanation:
Analysis:
For Change 1, which involves using multiple servers to maximize throughput and minimize response time, the key concern is how the load is distributed across these servers.
B: Load balancing:
* Load balancing is the process of distributing network or application traffic across multiple servers to ensure no single server becomes overwhelmed. It is crucial for maximizing throughput and minimizing response times, particularly during peak volumes.
Explanation of Incorrect Options:
* A: Connection pooling:
* This is related to managing database connections efficiently but is not directly relevant to distributing web server traffic.
* C: Distributed processing:
* This refers to dividing processing tasks across multiple processors or machines but is not specific to managing web server load.
* D: Caching:
* Caching helps improve performance by storing frequently accessed data in memory, reducing the need to retrieve it from the database, but it does not address load distribution across servers.
References:
The ISTQB CTAL-TTA syllabus and standard practices in reviewing system architecture emphasize the importance of load balancing for managing server traffic and ensuring optimal performance during peak loads.

NEW QUESTION # 45
A new reusable software component that handles sensor management has been developed. It will be used in manufacturing processes that work at SIL 2 and avionics systems where failure could lead to a "major" incident. The code contains no loops but does contain decisions with multiple conditions. Which of the following would be the BEST structure-based testing option for the new software?
- A. Statement coverage
- B. API coverage
- C. Decision coverage
- D. MC/DC coverage
Answer: D
Explanation:
* Context of the Problem:
* The software component handles sensor management.
* It is used in manufacturing processes that work at SIL 2 and avionics systems.
* Failure could lead to a "major" incident.
* The code contains decisions with multiple conditions and no loops.
* Safety Integrity Level (SIL) 2:
* SIL 2 indicates that the software must adhere to stringent safety standards.
* Avionics systems also require high safety standards due to the potential consequences of failure.
* Testing Options:
* MC/DC (Modified Condition/Decision Coverage):
* MC/DC is essential for high-integrity and safety-critical systems like avionics.
* Ensures each condition in a decision has been shown to independently affect the outcome.
* Required by standards such as DO-178C for avionics software at certain levels.
* API Coverage:
* Focuses on testing the interfaces between components.
* Important but not sufficient alone for high-integrity, safety-critical systems.
* Decision Coverage:
* Ensures that each decision point (i.e., if statements) is evaluated as both true and false.
* Less comprehensive than MC/DC for safety-critical applications.
* Statement Coverage:
* Ensures that each statement in the code has been executed at least once.
* Basic level of coverage, insufficient for safety-critical systems like those at SIL 2.
* Best Option:
* Given the high safety requirements (SIL 2, major incident potential), MC/DC coverage is the best option. It provides a thorough level of testing needed to meet safety standards.
NEW QUESTION # 46
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. Multiple condition testing
- B. Decision testing
- C. Statement testing
- D. Modified condition/decision testing
Answer: D
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 # 47
Consider the simplified logic below for crediting money to a bank account.
Receive money and account number to be credited
IF account number is valid
IF customer account is active
Store current account balance as oldBalance
Credit money to account
IF oldBalance < zero
IF balance now >= zero
Set message "Overdraft cleared"
ELSE
Set message "A/c overdrawn"
ENDIF
ELSE
Set message = "You have more money"
ENDIF
IF account holder is VIP customer
Send message by email to customer
ENDIF
ELSE
Set message "A/c inactive"
Send message by email to supervisor
ENDIF
ELSE
Add 1 to count of invalid inputs
ENDIF
What percentage of decision testing coverage has been achieved by the following suite of test cases?
Test Case A - Account number valid, account is active, oldBalance = -100, balance now = +200, not a VIP customer Test Case B - Account number valid, account is active, oldBalance = -100, balance now = -50, is a VIP customer
- A. 60%
- B. 40%
- C. 80%
- D. 70%
Answer: A
Explanation:
To determine the percentage of decision testing coverage achieved by the given suite of test cases, we need to analyze the decisions and outcomes in the provided logic.
Detailed Analysis
* Identify all decisions in the logic:
* IF account number is valid
* IF customer account is active
* IF oldBalance < zero
* IF balance now >= zero
* IF account holder is VIP customer
* Calculate the number of unique decisions:
* There are 5 unique decision points in the logic.
* Determine the possible outcomes for each decision:
* IF account number is valid 2 outcomes (True, False)
* IF customer account is active 2 outcomes (True, False)
* IF oldBalance < zero 2 outcomes (True, False)
* IF balance now >= zero 2 outcomes (True, False)
* IF account holder is VIP customer 2 outcomes (True, False)
Test Cases Analysis
Test Case A
* Account number valid True
* Account is active True
* OldBalance = -100 True (less than zero)
* Balance now = +200 True (greater than zero)
* Not a VIP customer False
Test Case B
* Account number valid True
* Account is active True
* OldBalance = -100 True (less than zero)
* Balance now = -50 False (less than zero)
* Is a VIP customer True
Coverage Calculation
To calculate the decision coverage, we need to see how many of the possible outcomes are covered by the test cases:
* IF account number is valid (True in both A and B, False not tested)
* IF customer account is active (True in both A and B, False not tested)
* IF oldBalance < zero (True in both A and B, False not tested)
* IF balance now >= zero (True in A, False in B, both outcomes tested)
* IF account holder is VIP customer (False in A, True in B, both outcomes tested) Out of the 10 possible outcomes (2 for each decision), the given test cases cover 6 outcomes:
* Account number valid True
* Account number valid False (not covered)
* Customer account active True
* Customer account active False (not covered)
* OldBalance < zero True
* OldBalance < zero False (not covered)
* Balance now >= zero True
* Balance now >= zero False
* Account holder is VIP True
* Account holder is VIP False
Thus, 6 out of the 10 outcomes are covered by the test cases, giving us a decision coverage percentage of:
Decision Coverage=(610)×100%=60%\text{Decision Coverage} = \left(\frac{6}{10}\right) \times 100\% =
60\%Decision Coverage=(106)×100%=60%
References:
* The sample questions and answers provided in the ISTQB CTAL-TTA documentation confirm this calculation method and the expected coverage percentage for similar logical scenarios.
NEW QUESTION # 48
The following epic has been written:
As a vehicle driver
I want to find an available space In a car park
So that I can pay in advance to reserve that space
This epic will be used to develop user stories for a new National Car Parking application Both public and private car park owners will be able to utilise the system, allowing drivers of all kinds to guarantee an available car parking space on arrival at their chosen car park, according to the kind of vehicle that they may drive There will be multiple stakeholders including different car park owners, different user groups including disabled drivers and different vehicle types such as car. van and motorbike.
From this epic, multiple user stories will be written. The following acceptance criteria have been written for the epic, and will be applicable to all user stories (each user story will also have its own acceptance cntena):
1.End-to-end response time for any individual request submitted by a user must not exceed 5 seconds
2.All correspondence with stakeholders must be via email and text message
3.The application must be accessible on most mobile technology
4.A user cannot submit a form unless all mandatory fields are entered
5.Payment method can be made using the most popular electronic options
Applying the INVEST technique to this epic, including its acceptance criteria, which of the following statements is correct?
SELECT ONE OPTION
- A. The Testable and Small criteria of INVEST have not been satisfied
- B. The invest criteria have all been satisfied by this epic
- C. The Independent and Small criteria of INVEST have not been satisfied
- D. The Testable and Valuable criteria of INVEST have not been satisfied
Answer: C
Explanation:
The epic described has broad and overarching objectives that span multiple user groups and stakeholders, making it inherently dependent on other functionalities within the same system. This fails the 'Independent' criterion of INVEST, which suggests features should be self-contained. Moreover, the epic's scope suggests it's quite large, likely requiring splitting into smaller, more manageable stories, thus not meeting the 'Small' criterion. INVEST aims for manageable, independent increments that can be developed and validated quickly .
NEW QUESTION # 49
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. 2 test cases
- D. 6 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 # 50
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. Security and Reliability
- B. Performance efficiency and Portability
- C. Reliability and Portability
- D. Reliability and Performance efficiency
Answer: C
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 # 51
You have conducted static analysis on several new modules for an existing product. You are now executing test cases and are seeing inconsistent problems including crashes. Intermittent error messages are appearing.
Despite all your best efforts, you are not able to find reproducible scenarios to force these errors.
What problem in the code are you likely seeing?
- A. Instrumented code
- B. Wild pointers
- C. Poor error handling
- D. Undefined variables
Answer: B
Explanation:
Experiencing inconsistent problems such as crashes and intermittent error messages that do not have reproducible scenarios likely points to an issue with wild pointers. Wild pointers are pointers that do not point to a valid object of the appropriate type, often due to being uninitialized, pointing to deallocated memory, or having been overwritten accidentally.
* Explanation: Wild pointers can lead to unpredictable behavior because they may point to random or previously freed memory locations, causing the application to crash or behave erratically when these pointers are dereferenced.
NEW QUESTION # 52
A unit test should be deterministic. Which option correctly describes the meaning of 'deterministic' as a characteristic of a unit test9 SELECT ONE OPTION
- A. it should not depend on any other test.
- B. It should be small so that many tests can be run in a short period of time
- C. It should only test the functionality related to it.
- D. Whenever it is run under the same conditions, it should produce the same results.
Answer: D
Explanation:
A unit test being 'deterministic' means that whenever it is run under the same conditions, it should produce the same results. This characteristic is crucial for reliable, repeatable testing outcomes that are not influenced by external factors or previous test states .
NEW QUESTION # 53
You are testing software that will be used in nuclear power plants. The particular piece of code you are testing has been classified as SIL 2. The following section of code falls under this classification:
If ((A > B) or (C > D)) and (E = F) then print A
Endif
Which of the following sets of test data would supply the minimum tests needed to achieve the "highly recommended" level of coverage?
- A. Set 3
- B. Set 5
- C. Set 2
- D. Set 1
Answer: D
Explanation:
In software testing, especially within contexts like nuclear power plants, achieving a "highly recommended" level of coverage often requires strategic test case selection to verify all logical conditions are accurately assessed. For the condition "If ((A > B) or (C > D)) and (E = F) then print A", the critical tests involve evaluating the boolean logic.
* Test Case Analysis: Test Set 1 is selected because it should ideally include scenarios where:
* Both conditions (A > B) and (C > D) are true, and (E = F) is true to ensure the print statement executes.
* One of the conditions (A > B) or (C > D) is false while the other is true, combined with (E = F) being true, to test the OR logic.
* Both conditions (A > B) and (C > D) are false with (E = F) being true, which should not trigger the print statement, testing the AND logic.
* Condition where (E != F), irrespective of other conditions, to confirm that the print statement does not execute.
NEW QUESTION # 54
How many independent paths are shown in the control flow diagram below?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
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 # 56
What is the common name for a type of automated testing technique that separates test input data and expected test results from the control script used to execute all of the tests?
- A. Keyword-driven testing
- B. Data-based testing
- C. Model-driven testing
- D. Behavior-based testing
Answer: A
Explanation:
The common name for the automated testing technique that separates test input data and expected results from the control script is Keyword-driven testing. In this approach, test scripts are written using keywords related to the application under test, which are easy to read and can be interpreted by a script engine to perform testing actions.
* Explanation: This methodology allows for the reusability of scripts and easier maintenance because the test data and the scripts that use the data are maintained separately.
NEW QUESTION # 57
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. Performance Efficiency
- B. Usability
- C. Maintainability
- D. Portability
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 # 58
Below is the pseudo-code for the Win program:
The bingo program contains a data flow anomaly. Which data flow anomaly can be found in this program?
- A. Variable 'D" is defined but subsequently not used.
- B. Variable 'A" is not assigned a value before using it.
- C. The program does not contain any comments.
- D. It is recommended to use a variable instead of the hard-coded print results "Win" and *Loose".
Answer: A
Explanation:
The pseudo-code provided for the "Win" program reads in variables A, B, C, and D. However, only variables A, B, and C are used in the conditional statements to determine if the output will be "Win" or "Loose".
Variable 'D' is never used after it is read, which is a classic example of a 'defined but not used' data flow anomaly. This means that while there is an instruction to read a value into variable 'D', there is no subsequent use of this variable in the program's logic or output.
NEW QUESTION # 59
A new web site has been launched for a testing conference. There are a number of links to other related web sites for information purposes. Participants like the new site but complaints are being made that some (not all) of the links to other sites do not work.
Which type of test tool is most appropriate in helping to identify the causes of these failures?
- A. Static analysis tool
- B. Review tool
- C. Hyperlink tool
- D. Dynamic analysis tool
Answer: C
Explanation:
When users complain about issues with links on a website, the most appropriate test tool to identify the causes of these failures is a hyperlink tool (answer B). Hyperlink tools are specifically designed to check the validity of links on web pages. They can automatically identify broken or dead links, which is essential for maintaining the quality and user experience of a website. Review tools, static analysis tools, and dynamic analysis tools do not primarily focus on hyperlink verification.
NEW QUESTION # 60
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. Replaceability
- C. In stall ability
- D. Adaptability
Answer: B
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.
