NEW QUESTION # 59
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. Will the system use n-version programming for critical components?
C. Will the user interface be implemented independently from the other software modules?
D. Does the system have user-friendly error messages?

Answer: C

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 # 60
A project to develop a new system has performance efficiency listed as a critical requirement. Which of the following describes how and when the Technical Test Analyst should FIRST be involved in performance test activities for the new system?

A. Participating in code reviews that focus on database and component interactions as well as error handling
B. Implementing the performance tool's load test scripts, for execution in a production-like environment during system test
C. Assisting the developers in determining CPU utilization for critical components during component testing
D. Designing an operational profile that does not exceed hardware, software, and network bandwidth test environment budgets

Answer: D

Explanation:
Analysis:
When performance efficiency is a critical requirement, the involvement of the Technical Test Analyst (TTA) is crucial from the early stages of the project to ensure performance goals are met.
Key Activity:
A: Designing an operational profile that does not exceed hardware, software, and network bandwidth test environment budgets:
* This activity involves creating a realistic operational profile that reflects how the system will be used in production. It ensures that performance testing is aligned with actual usage patterns and resource
* constraints. By doing this early, TTAs can identify potential performance issues and make necessary adjustments before development progresses too far.
Explanation of Incorrect Options:
* B: Participating in code reviews that focus on database and component interactions as well as error handling:
* While useful, this is more relevant to ensuring code quality and correctness rather than the first step in addressing performance efficiency.
* C: Assisting the developers in determining CPU utilization for critical components during component testing:
* This is a more detailed activity that follows the establishment of the operational profile and overall performance requirements.
* D: Implementing the performance tool's load test scripts for execution in a production-like environment during system test:
* This occurs later in the testing process, after the operational profile has been designed and the initial performance considerations have been addressed.
References:
The ISTQB CTAL-TTA syllabus highlights the importance of designing operational profiles and understanding resource constraints as initial steps in performance testing.

NEW QUESTION # 61
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 5
B. Set 3
C. Set 1
D. Set 2

Answer: C

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 # 62
When conducting a data flow analysis of following section of pseudo code:
Declare Function_Biggest integer (inputl integer. Input2 Integer) }
Declare output Integer
Set output = inputl
If input2 > output then
Set output = input2
Endif
Return output
}
Which of the variables utilized above has a potential anomalie?

A. Inputl and input2
B. Function_Biggest
C. None of the variables
D. output

Answer: D

Explanation:
In the data flow analysis of the pseudocode, the variable output presents a potential anomaly. Initially, output is set to input1, but it may be overwritten if input2 is greater. The anomaly, specifically a 'definition-use' (du-path) issue, arises because there might be scenarios where output does not adequately reflect changes depending on the dynamic data flow influenced by the conditional. Proper testing and validation of such conditional structures are crucial to ensure that output consistently represents the largest of the two inputs as intended.

NEW QUESTION # 63
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 # 64
You have been given this piece of pseudocode to review Assume that the variables have been declared set and validated in code that precedes this piece that you are reviewing Looking only at this part of the code what requires further discussion?
If a < b then
If a > 12 then
seta = 21
else
set a = 23
endif
If b < 17 then
set a = 24
endif
lfb> 14
set a = 25
set b = 10
else
set a = 5
endif
else
set a = 7
endif

A. A loop should have been used rather than the embedded if statements
B. An else statement may be missing
C. A variable should not be set to multiple values within one code segment
D. Embedded if statements should not be used

Answer: B

Explanation:
The pseudocode presented for review exhibits a likely issue with the control structure, particularly a missing else statement. This inference is drawn from the unbalanced opening and closing of conditional statements.
The inner conditional structures suggest alternative outcomes based on several conditions, but the snippet likely misses an else statement associated with the condition lfb > 14, which could lead to ambiguous or unintended code behavior when lfb <= 14. Such issues can make the code difficult to maintain and could introduce bugs if not addressed. Ensuring each if has a corresponding else can prevent such potential errors in branching logic.

NEW QUESTION # 66
BestFor Incorporated is a rapidly growing online financial services company that offers guidance to its customers on a range of financial products. Its first website, BestForMortgages, was launched two years ago, shortly followed by BestForPensions. The popularity of both sites has driven the company to expand its offerings into other sectors and a third website, BestForFood, is currently under development.
The first two websites have proven to be functionally robust but suffered from performance issues due to:
Underestimation of concurrent user access at peak times in its original operational profiles Data volumes rapidly growing beyond expectations on a single database shared by both sites.
All three websites will share the same web server.
In consideration of the problems encountered with the first two websites, which TWO of the following types of testing should be performed on the BestForFood website to see whether similar defects exist?
A) Load Testing
B) Stress Testing
C) Scalability testing
D) Portability Testing
E) Recoverability testing

A. b and c
B. a and c
C. d and e
D. b and d

Answer: B

Explanation:
Analysis:
Given the problems encountered with the first two websites, the types of testing needed for the BestForFood website should address similar issues related to performance under peak load and data volume growth.
* Load Testing:
* Load testing helps identify the behavior of the website under expected user load conditions. It simulates multiple users accessing the website simultaneously to ensure it can handle peak traffic without performance degradation. This is essential given the underestimation of concurrent user access for the first two websites.
* Scalability Testing:
* Scalability testing evaluates how well the system can handle increased loads by scaling up its resources, such as adding more servers or increasing database capacity. This is crucial for ensuring that the website can manage rapid data volume growth and increased user traffic over time.
Explanation of Incorrect Options:
* B. Stress Testing:
* Stress testing pushes the system beyond its normal operational capacity to identify breaking points. While important, it is more extreme than necessary for addressing the issues of underestimated user access and data volume growth.
* D. Portability Testing:
* Portability testing assesses how well the software can be moved from one environment to another, which is not directly related to the performance issues described.
* E. Recoverability Testing:
* Recoverability testing ensures the system can recover from failures, which is not the primary concern here.
References:
The ISTQB CTAL-TTA syllabus covers different types of non-functional testing and their relevance. Load and scalability testing are emphasized for addressing performance and capacity-related risks.

NEW QUESTION # 68
Which of the following is true regarding maintainability?

A. This factor will influence the performance of the system
B. This factor becomes more Important the longer the system remains in the production environment
C. This factor affects resource utilization
D. This factor Is critical for the initial success of the product launch

Answer: B

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 # 69
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. 4 test cases
B. 8 test cases
C. 6 test cases
D. 2 test cases

Answer: A

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 # 70
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. Data-based testing
B. Keyword-driven testing
C. Model-driven testing
D. Behavior-based testing

Answer: B

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 # 73
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. An invalid value is assigned to variable "B".
D. The hard-coded value '2" should not be used.

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 # 74
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. b and d
C. c and e
D. a and b

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 # 75
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 # 76
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. 4 test cases
