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. Select_Client
- B. Exclude_Client
- C. Print_Premium
- D. Remove_Client
- E. Enter_Client
Answer: A,E
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 # 62
You are defining the test approach for an Agile project developing a system to control traffic lights at busy road junctions. The system will use sensors to measure traffic density and flow rates, optimizing traffic flow.
While safety-critical, a risk assessment has deemed the project's risk level as low due to the team's expertise.
Which option below represents the BEST test approach for this project?
Key to symbols:
* + (highly recommended)
* (recommended)
* o (neutral/optional)
* * (not recommended)
* - (not to be used)
SELECT ONE OPTION
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
In the scenario described, the project involves developing a system to control traffic lights at busy road junctions, focusing on safety-critical operations but deemed low-risk due to the team's high level of expertise.
Option B (4), characterized by (recommended) for Test Automation and + (highly recommended) for Exploratory Testing (manual) with (recommended) for Black-box Testing, is the most fitting for this project because:
* Test Automation (Recommended): For a system managing traffic lights, automated tests can efficiently handle repetitive testing of scenarios involving various traffic densities and flow rates, ensuring consistent and thorough checking of system responses under controlled conditions.
* Exploratory Testing (Highly Recommended): Given the critical nature of the system, exploratory testing allows testers to creatively challenge the system beyond pre-defined test cases, identifying potential real-world issues that might not be evident in scripted testing. This is particularly vital in safety-critical systems where unexpected behavior could have severe consequences.
* Black-box Testing (Recommended): Black-box testing will ensure that the system meets its external specifications and behaves correctly as perceived from the outside, without the testers needing to know the internal workings. This is essential for verifying that the system's functionality aligns with its intended use in real-world traffic scenarios.
This approach, combining thorough automation with exploratory insights and specification-based validation, supports the project's safety-critical nature while leveraging the team's expertise to manage the identified low risk .
NEW QUESTION # 63
Your team is developing an e-shop application (the SUT) that will use a third-party service to process payments via an API. This third-party payment gateway is itself still under development Which statement contains a pair of benefits that can BOTH be expected from service virtualization in this circumstance' SELECT ONE OPTION
- A. Earlier testing of the API, reduction in the amount of test data needed
- B. Realistic testing of the SUT before the actual payment gateway is available, simplification of the test environment
- C. Earlier discovery of defects in the SUT; the ability to share code between the SUT and the payment gateway.
- D. Parallel compilation, continuous integration, and test automation; more effective configuration management.
Answer: B
Explanation:
Service virtualization in the context of developing an e-shop application with an external payment gateway (still under development) offers significant benefits. It allows for realistic testing of the System Under Test (SUT) by simulating the behavior of the still-developing payment gateway, thus enabling testing to proceed without the actual service being available. Additionally, it simplifies the test environment by reducing the complexities associated with integrating and maintaining a live external service during development and testing phases .
NEW QUESTION # 64
You work for a small supermarket chain which has successfully operated a product inventory application for several years. It has recently purchased a data warehousing solution which provides tailorable profiling of product purchases with the aim of improving its marketing strategy. The decision has been made to host the data warehousing software and database on the same server used by the product inventory application. Based on this decision, two product risks have been cataloged:
The co-existence of both applications on the same server may introduce resource conflicts, resulting in an unacceptable impact on the functionality of the product inventory application In the event of loss or corruption of product inventory data during transfer to the warehouse, it may not be possible to restore from back-up in the timeframe required, resulting in lost business.
Which TWO non-functional test types should be included in the test plan to mitigate both product risks?
- A. Load testing and Portability testing
- B. Compatibility testing and Reliability testing
- C. Reliability testing and Stress testing
- D. Maintainability testing and Load testing
Answer: C
Explanation:
In this scenario, the small supermarket chain faces two primary risks due to hosting both the data warehousing software and the product inventory application on the same server:
* Resource Conflicts: Co-existence of both applications on the same server may introduce resource conflicts, potentially impacting the functionality of the product inventory application.
* Data Loss/Corruption: In the event of loss or corruption of product inventory data during transfer to the warehouse, it may not be possible to restore from backup in the required timeframe, resulting in lost business.
Appropriate Non-Functional Test Types:
* Reliability Testing (Option C):
* Reliability testing ensures that the system performs consistently and accurately over time, even under load. This will help in identifying potential issues related to data loss or corruption and ensure that backup and restore processes work as expected within the required timeframe.
* Stress Testing (Option C):
* Stress testing evaluates the system's behavior under extreme conditions, such as peak loads. This will help in identifying resource conflicts and the system's ability to handle concurrent operations of both the data warehousing software and the product inventory application without performance degradation.
Explanation of Incorrect Options:
* A. Compatibility Testing and Reliability Testing:
* Compatibility testing is not directly relevant to the identified risks. Reliability testing is correct, but it needs to be paired with stress testing to address resource conflicts effectively.
* B. Load Testing and Portability Testing:
* Load testing alone does not cover the extreme conditions needed to identify resource conflicts.
Portability testing is not relevant to the identified risks.
* D. Maintainability Testing and Load Testing:
* Maintainability testing is not directly relevant to the immediate operational risks. Load testing is part of the solution but needs to be paired with stress testing.
References:
The ISTQB CTAL-TTA syllabus covers various non-functional testing types and their relevance to different risk scenarios. Reliability and stress testing are crucial in this context to ensure the system can handle concurrent applications and maintain data integrity under load.

NEW QUESTION # 65
Consider the following pseudocode segment:
set a = 1
while a < 12
display "this is loop", a
if a > 10 then
display "loop is > 10'
set a = 5
else
display "loop is < 11*
endif
end while
display "Final value of a is", a
Which of the following issues should be detected in the code review?
- A. Some of the code could be moved to re-usable functions
- B. Rounding errors on the loop counters could cause problems
- C. Loop termination is not achievable
- D. Variables are used before they are initialized
Answer: C
Explanation:
The pseudocode provided includes a while loop that adjusts the loop variable a within the loop's conditional code block. This adjustment, set a = 5, occurs when a > 10. Because the loop checks a < 12 as its continuation condition, and a is reset to 5 repeatedly once it exceeds 10, the loop will execute indefinitely, preventing termination. This creates an infinite loop situation since the condition a < 12 will perpetually remain true once a exceeds 10. This is a critical logic error needing correction for proper execution flow.
NEW QUESTION # 66
Which of the following is NOT a common issue with traditional capture/playback test automation?
- A. Difficult to maintain when software changes.
- B. Execution of the recorded script is difficult outside office hours.
- C. Data and actions are mixed in the recorded script.
- D. Recorded scripts are difficult to maintain by non-technical persons.
Answer: B
Explanation:
Common issues with traditional capture/playback test automation include difficulty in maintaining the scripts when software changes (option A), the challenge for non-technical persons to maintain recorded scripts (option B), and the issue that data and actions are often intertwined within the recorded script (option C), which can make them hard to understand and modify. However, the timing of the execution of the recorded script (option D), such as the difficulty of running scripts outside office hours, is not typically a problem inherent to capture/playback test automation itself but rather an environmental or scheduling issue.
NEW QUESTION # 67
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 2?
- A. Lazy instantiation
- B. Data replication
- C. Connection pooling
- D. Caching
Answer: A
Explanation:
Analysis:
For Change 2, the goal is to prevent unnecessary database calls by delaying the creation of database connections until they are actually needed. This approach is known as lazy instantiation.
C: Lazy instantiation:
* Lazy instantiation is a design pattern that defers the creation of an object until the point at which it is needed. This can help improve performance by reducing unnecessary resource consumption. In the context of database connections, it ensures that connections are only established when required, thus avoiding unnecessary overhead.
Explanation of Incorrect Options:
* A. Connection pooling:
* Connection pooling involves reusing database connections from a pool rather than creating new ones each time. While this improves efficiency, it does not specifically address the issue of deferring database connections until needed.
* B. Data replication:
* Data replication refers to copying data across multiple databases to ensure consistency and availability. It is not directly related to managing when database connections are established.
* D. Caching:
* Caching involves storing frequently accessed data in memory to improve retrieval times. While beneficial for performance, it does not address the specific issue of delaying database connections.
References:
The ISTQB CTAL-TTA syllabus and standard software architecture practices highlight the importance of design patterns such as lazy instantiation for optimizing resource usage and performance.

NEW QUESTION # 68
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. Behavior-based testing
- B. Data-based testing
- C. Keyword-driven testing
- D. Model-driven testing
Answer: C
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 # 69
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=6, B=12, Expected output: Bingo!
- B. No additional test cases are needed to achieve 100% statement coverage.
- C. A=7, B=9, Expected output: 7
- D. A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
Answer: B
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.

NEW QUESTION # 71
Within the world of consumer electronics, the amount of embedded software is growing rapidly. The amount of software in high-end television sets has increased by a factor of about eight over the last six years. In addition, the market of consumer electronics has been faced with a 5 -10% price erosion per year. The price of a product is, among a number of other things, determined by the microcontroller used. Therefore, the use of ROM and RAM remains under high pressure in consumer electronic products, leading to severe restrictions on code size.
Within a new high-end TV project, it has been decided to apply dynamic analysis.
Which of the quality goals listed below is MOST appropriate to the project context?
- A. Improve system performance by providing information on run-time system behaviour.
- B. Analyse system failures which cannot easily be reproduced.
- C. Prevent failures from occurring by detecting wild pointers and loss of system memory.
- D. Evaluate network behaviour.
Answer: A
Explanation:
In the context of consumer electronics, where there is rapid growth in embedded software and pressure to minimize code size due to cost constraints, dynamic analysis can be particularly useful for improving system performance. Dynamic analysis involves examining the system's behavior during execution, which can provide insights into the efficiency of the code at runtime, memory utilization, and processing speed. In a high-end TV project where the use of ROM and RAM is under severe restrictions, dynamic analysis would be most appropriately applied to improve system performance, ensuring that the software runs efficiently within the available hardware resources. This supports the project context by contributing to the optimization of the software to run within the constraints of the microcontroller used, thereby potentially reducing costs.
NEW QUESTION # 72
Consider the following specification:
If you are flying with an economy ticket, there is a possibility that you may get upgraded to business class, especially if you hold a gold card in the airline's frequent flier program. If you don't hold a gold card, there is a possibility that you will get 'bumped' off the flight if it is full when you check in late.
This is shown in the control flow graph below. Note that each box (i.e., statement, decision) has been numbered.
Three tests have been run:
Test 1: Gold card holder who gets upgraded to business class
Test 2: Non-gold card holder who stays in economy
Test 3: A person who is bumped from the flight
What is the level of decision coverage achieved by these three tests?
- A. 67%
- B. 75%
- C. 80%
- D. 60%
Answer: A
Explanation:
The control flow graph provided illustrates the decision points for an airline's upgrade and boarding process.
Decision coverage is a measure of the percentage of decision points executed during testing:
* Test 1 covers the decision points: Gold card? (Yes) and Business full? (No).
* Test 2 covers: Gold card? (No) and Economy full? (No).
* Test 3 covers the decision that leads to being bumped from the flight, which is Economy full? (Yes) and Business full? (Yes).
From the given tests, the decision points for Gold card? (No) and Business full? (No) are not tested, leaving us with 4 out of 6 decision points covered, which is approximately 67% decision coverage.
NEW QUESTION # 73
Which of the following is true regarding maintainability?
- A. This factor will influence the performance of the system
- B. This factor affects resource utilization
- C. This factor becomes more Important the longer the system remains in the production environment
- D. This factor Is critical for the initial success of the product launch
Answer: C
Explanation:
Maintainability refers to how easily software can be maintained over time to correct faults, improve performance, or adapt to a changed environment. This quality factor becomes increasingly important the longer the system remains in the production environment because as systems age, they often require updates and modifications to continue meeting user needs effectively. This factor is critical for ensuring the system can be efficiently updated without causing downtime or significant expense.
NEW QUESTION # 74
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 'A" is not assigned a value before using it.
- B. Variable 'D" is defined but subsequently not used.
- 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: B
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 # 75
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 "MIN" is not assigned a value before using it.
- B. Variable "AB is defined but subsequently not used.
- C. The hard-coded value '2" should not be used.
- D. An invalid value is assigned to variable "B".
Answer: A
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 # 76
In what circumstances should you use a simulator instead of an emulator when testing a mobile application?
- A. When security is not a consideration
- B. When a model of the runtime environment Is sufficient for testing
- C. When there is a need to assess the usability of the application
- D. When the hardware device and the runtime environment must be modeled
Answer: B
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 # 77
When planning and specifying security tests which of the following is NOT likely to be a useful part of the approach?
- A. Ensuring that appropriate tools will be available for static analysis
- B. Planning extra performance efficiency and reliability tests
- C. Identifying those from whom permission might be needed to run the tests
- D. Re-assuring the (non-technical) Test Analysts that they will not need to be involved
Answer: D
Explanation:
Analysis:
When planning and specifying security tests, it's essential to consider several critical aspects:
A: Identifying those from whom permission might be needed to run the tests:
* True. It is crucial to get the necessary permissions, especially for penetration testing or other security tests that could be intrusive.
B: Re-assuring the (non-technical) Test Analysts that they will not need to be involved:
* False. Security testing often requires a coordinated effort, and non-technical test analysts might still have roles, such as documentation, coordination, or assisting in test preparation. Excluding them entirely could lead to gaps in understanding and execution.
C: Ensuring that appropriate tools will be available for static analysis:
* True. Having the right tools is vital for effective security testing, including static analysis tools for identifying vulnerabilities in the code.
D: Planning extra performance efficiency and reliability tests:
* True. Performance efficiency and reliability are often linked to security (e.g., DoS attacks), so planning these tests is useful.
Explanation of Incorrect Option:
* B: Excluding non-technical test analysts might undermine the testing process as they can still contribute in various supportive roles.
References:
The ISTQB CTAL-TTA syllabus covers security testing and the planning required, highlighting the need for comprehensive involvement of all relevant stakeholders.

NEW QUESTION # 78
Consider the pseudo code for the Answer program:
Which of the following statements about the Answer program BEST describes the control flow anomalies to be found in the program?
- A. The Answer program contains unreachable code.
- B. The Answer program contains no control flow anomalies.
- C. The Answer program contains unreachable code and an infinite loop.
- D. The Answer program contains an infinite loop.
Answer: C
Explanation:
The provided pseudo code for the Answer program shows a WHILE loop that will always execute because the condition for the loop to terminate (a >= d) is never met within the loop's body. This results in an infinite loop.
Additionally, since the value of 'b' is initialized with 'a + 10' and 'a' starts from a value that is read and then set to 2, 'b' will never be equal to 12. Therefore, the 'THEN' branch of the IF statement, which includes 'print(b)', is unreachable. These are control flow anomalies because they represent logic in the code that will not function as presumably intended.
