NEW QUESTION # 103
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. 75%
- B. 80%
- C. 60%
- D. 67%
Answer: D
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.

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: A
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 # 105
Consider the following control flow graph:
The control flow represents a software component of a car navigation system. Within the project the maximum cyclomatic complexity to be allowed is set at 5.
Which of the following statements is correct?
- A. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 4
- B. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 5.
- C. No defect needs to be reported since the cyclomatic complexity of the component is calculated at 3.
- D. A defect needs to be reported since the cyclomatic complexity of the component is calculated at 6.
Answer: D
Explanation:
Cyclomatic complexity is a measure of the number of linearly-independent paths through a program's source code, which is often used as a measure of the complexity of a program. The control flow graph provided represents the logic of a software component and has more than 5 nodes with decision points, indicating that the complexity would exceed the maximum allowed value of 5. The calculation for cyclomatic complexity is V(G) = E - N + 2P, where E is the number of edges, N is the number of nodes, and P is the number of connected components. In this case, the calculated cyclomatic complexity exceeds the allowed threshold, thus a defect should be reported.

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 # 110
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. Unreachable code
- B. Endless loop
- C. Too many nested levels
- D. No defects should be reported, code is correct.
Answer: B
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.

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. Loop termination is not achievable
- B. Rounding errors on the loop counters could cause problems
- C. Some of the code could be moved to re-usable functions
- D. Variables are used before they are initialized
Answer: A
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 # 124
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. Caching
- B. Connection pooling
- C. Lazy instantiation
- D. Data replication
Answer: C
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.
