ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions (Q173-Q178):

NEW QUESTION # 173
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. b and d
  • B. a and b
  • C. c and e
  • D. a and c

Answer: D

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 # 174
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 no control flow anomalies.
  • C. The Price program contains an infinite loop.
  • D. The Price program contains unreachable code.

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 # 175
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 d
  • B. b and c
  • C. a and c
  • D. d and e

Answer: C

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.

* ISTQB-CTAL-TTA Syllabus
* General knowledge on non-functional testing practices.


NEW QUESTION # 176
You are working for a company that has a product in the field that has reached its capacity. The system cannot handle any more users without a significant degradation in performance and a significant spike in resource requirements. As a result, your new product has strict requirements for performance efficiency and a specific growth requirement that is estimated for the next three years.
What type of testing should you conduct to make sure the future requirements will be met?

  • A. Scalability testing
  • B. Stress testing
  • C. Load testing
  • D. Time-behavior testing

Answer: A

Explanation:
For a product that has reached its capacity limits and requires testing to ensure it can handle projected growth, scalability testing is the most appropriate. Scalability testing evaluates a system's ability to manage an increasing workload without compromising performance or other operational capabilities. This type of testing will help confirm whether the system can handle the estimated increase in load, which is aligned with the strict performance efficiency and growth requirements for the next three years


NEW QUESTION # 177
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. An invalid value is assigned to variable "B".
  • B. Variable "AB is defined but subsequently not used.
  • C. Variable "MIN" is not assigned a value before using it.
  • D. The hard-coded value '2" should not be used.

Answer: C

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 # 178
