ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions (Q119-Q124):

NEW QUESTION # 119
You are responsible for the non-functional testing of a website supporting a popular restaurant chain. Due to the rapid expansion of the number of restaurants in the chain, the company is expecting the peak number of concurrent website views to more than triple in the next 6 months. As a result, it has purchased two further production servers to support the existing one. A new hardware release has been scheduled for which the following product risk has been recorded:
(Insert Table 2)
Which one of the following non-functional test typos would be BEST to mitigate this risk?

A. Adaptability testing
B. Load testing
C. Reliability testing
D. Scalability testing

Answer: D

Explanation:
In this scenario, the risk is related to the anticipated increase in concurrent website views and whether the additional servers will be sufficient to handle the increased load. This situation requires a specific type of non-functional testing to ensure that the system can effectively scale with the increased demand.
Analysis of Options:
* Load Testing:
* Load testing involves simulating a specified number of users to see how the system performs under expected loads. While this is useful, it is not the best fit for this scenario where the primary concern is future scaling capacity.
* Adaptability Testing:
* Adaptability testing assesses how well the system adapts to different environments or conditions.
This is not directly related to the risk of handling increased concurrent users and is therefore not the best choice.
* Scalability Testing (Option C):
* Scalability testing specifically evaluates how well the system can scale up or down in response to an increase in load. This type of testing is designed to verify that the system can handle growth in users and data volume effectively, making it the best choice to mitigate the risk described.
* Reliability Testing:
* Reliability testing focuses on the system's ability to function correctly over time under certain conditions. While reliability is important, it does not directly address the issue of handling increased concurrent usage.
Mitigating the Risk:
Given the risk of the servers potentially not being adequate to handle the increased concurrent website views, scalability testing is the most appropriate type of non-functional testing. It will help determine if the two additional servers, along with the existing one, can support the anticipated growth in user traffic without performance degradation.
References:
The ISTQB CTAL-TTA syllabus and standard non-functional testing practices emphasize the importance of scalability testing when assessing the ability of a system to handle increased load and user concurrency.
Sources:
* ISTQB-CTAL-TTA Syllabus
* General knowledge on non-functional testing types and their applications.

NEW QUESTION # 120
You need to implement a Java class that validates a password entry field. The validation critena states that the password must:
1. be a minimum of 8 characters
2 contain at least one special character.
You are focusing on validation criterion 1 and have written a test class that checks that a 7 character password entry will fail validation.
You have written code designed to make this test class pass, however, on first execution of the test class it has failed What should you do next9 SELECT ONE OPTION

A. Develop a test class with a 9 character password containing one special character and re-execute the code
B. Repair the failing code and re-execute it for the test class
C. Refactor the failing code to improve its design and structure
D. Add code to cover special character validation criterion 2

Answer: B

Explanation:
When a test class that validates a specific criterion (such as the minimum length of a password) fails, the immediate next step is to repair the failing code and re-execute the test. This approach adheres to the test-driven development (TDD) practices, where the cycle of writing a failing test, making it pass, and then refactoring is repeated. It ensures that each validation criterion is correctly implemented before moving on to additional functionalities or validations .

NEW QUESTION # 121
What is the earliest stage in the application's SDLC at which performance efficiency testing can be performed?

A. During system testing
B. During unit testing
C. During beta testing
D. During requirements analysis

Answer: D

Explanation:
The earliest stage in the application's SDLC at which performance efficiency testing can be performed is during requirements analysis. At this stage, performance requirements and goals are established, providing a baseline for what needs to be tested and verified throughout the later stages of development.

NEW QUESTION # 122
You are working on a project to develop an application that allows users to collaborate via bespoke, online whiteboards. The first release, delivering core functionality, highlighted misunderstandings of the user stories between testers, developers and the product owner during sprint development Since that release, the developers have agreed to implement a TDD approach for future software development.
Creation of the product backlog for the second release is underway and you have recommended to the project stakeholders that an atdd approach be adopted for the backlog's user stories. What would be a GOOD REASON for making this recommendation?
SELECT ONE OPTION

A. TDD can only work effectively when an ATDD approach is used for the user stories use of attd examples will help address the misunderstandings encountered in release 1
B. The test strategy states that automation shall be used to minimize effort for execution of acceptance tests
C. The team wants to start using BDD and therefore atdd must also be used

Answer: A

Explanation:
Adopting an Acceptance Test-Driven Development (ATDD) approach can be particularly beneficial in scenarios where previous releases have suffered from misunderstandings among the development team and stakeholders regarding user story requirements. ATDD involves creating executable specifications before coding begins, which clarifies expectations and ensures alignment across the team. This method helps prevent issues seen in earlier stages by providing a clear, agreed-upon criteria for acceptance, thereby reducing the chances of future misunderstandings .

NEW QUESTION # 123
The following user story has been written:
As a paying hotel guest
I want to see the charges that have been added to my bill
So that I can monitor my expenditure and know In advance how much I will have to pay when I check out The notes that have been added to It mention that It must be possible for the guest to get a printout of the bill, see It In a variety of currencies and set a flag in the hotel's billing system against any Item that they wish to challenge.
The following acceptance criteria have been defined:
1.The user shall be able to choose from the most commonly-used currencies.
2.The application must be accessible on most mobile platforms as well as on the hotel room's smart TV.
3.The hotel manager must be notified whenever a bill item is flagged by a hotel guest.
4.End-to-end response time for any individual request submitted by a user must not exceed 7 seconds.
Applying the INVEST technique to this user story, including its acceptance criteria, which of the following statements is correct?
SELECT ONE OPTION

A. The Negotiable and Small criteria of INVEST have not been satisfied
B. The Testable and Negotiable criteria of INVEST have not been satisfied
C. The Testable and Small criteria of INVEST have not been satisfied
D. The INVEST criteria have all been satisfied by this epic

Answer: C

Explanation:
According to the INVEST criteria, the Testable and Small criteria have not been satisfied for the user story provided. Option B is correct.
* INVEST Criteria: The INVEST model stipulates that user stories should be Independent, Negotiable, Valuable, Estimable, Small, and Testable.
* Analysis of the User Story: The scope of the user story and its acceptance criteria suggests it is too broad (thus not 'Small') and the details provided, especially regarding response times and system notifications, imply potential challenges in effectively testing the story (thus possibly not 'Testable') without further refinement or breaking down the story into smaller, more manageable pieces.
The size and complexity of the requirements indicate that the story might be better classified as an epic, needing decomposition into smaller, more specific user stories that can be more feasibly addressed within agile iterations .
