ISQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing Sample Questions (Q17-Q22):

NEW QUESTION # 17
Base Scenario 2 : This Base Scenario 2 is used for 8 questions throughout this exam. When you refer to Base Scenario 2, you are referring to this description and only this description, without any modification.
Natalie works for a company that develops an online check-in management software for a major international airline.
Online check-in is available for passenger check-in from 24 to 1 hour before boarding time.
Once the registration is confirmed by the customer and the system, the information must be available to the rest of the types of users (flight managers, among others) in a maximum time of 3 seconds (it is expected that this temporal constraint is met in 90% of the transactions and that 90% of the transactions are completed at 100%).
At the beginning of the check-in window, there are peaks of 100 users per minute, for one minute.
Question
Which of the following options is a performance-related business objective that could be suitable for this project?
SELECT ONE OPTION

  • A. The system must be able to support peak attendance of 1,000 users, considering that there cannot be more than two flights with overlapping schedules.
  • B. The system must have a completion time of up to three seconds for 2,000 concurrent users for updating passenger check-in data
  • C. The system must be able to support 200 concurrent users with a response time of one second for the issuance of the boarding pass, considering that the fleet is likely to have a very high percentage of medium size aircraft.
  • D. The system must be capable of supporting peak concurrent users in excess of 6,000 users per hour for one minute, accessing check-in without performance degradation, considering that peaks must not exceed a value that exceeds the processing capacity of the system.

Answer: D

Explanation:
Given the scenario of online check-in with peak user activity, the most suitable performance-related business objective would be to ensure that the system can handle a high number of concurrent users within a short period without performance degradation. Option A directly addresses the requirement to support peak loads while maintaining system performance, which aligns with the specified peak of 100 users per minute.

NEW QUESTION # 18
If George is testing in order to check the stability of a system for a specific period of time in an operational system context, what type of testing is MOST appropriate?
SELECT ONE OPTION

  • A. Endurance testing.
  • B. Capacity testing.
  • C. Spike testing.
  • D. Load testing.

Answer: A

Explanation:
Endurance testing, also known as soak testing, evaluates the stability and performance of a system over an extended period under a significant load. This type of testing is designed to identify issues such as memory leaks, resource depletion, and other long-term stability problems that may not be evident in shorter testing durations. According to ISTQB guidelines, endurance testing is essential for ensuring that the system can maintain performance and stability over time, especially in operational contexts.


NEW QUESTION # 19
Identify the activity that is NOT part of the performance test preparation.
SELECT ONE OPTION

  • A. Virtualizing the servers.
  • B. Setting up the load generation and monitoring tools and making sure that all the necessary information will be collected.
  • C. Setting up the system under test.
  • D. Deploying the environment.

Answer: A

Explanation:
Virtualizing the servers is not typically part of performance test preparation. Performance test preparation generally involves activities such as deploying the test environment, setting up the system under test, and configuring load generation and monitoring tools to ensure accurate data collection. While virtualization can be an aspect of the overall infrastructure setup, it is not a direct step in preparing for performance testing. ISTQB performance testing guidelines emphasize setting up the environment, system, and tools specifically for performance test execution.


NEW QUESTION # 20
(REFER TO BASE SCENARIO 2): When you refer to Base Scenario 2, you are referring to the description and only the description, without any modification.
Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
Throughout the month of January (31 days), the company performed 3,100 departure operations from the Capital City Airport. These departure operations transported 465,000 passengers during the hours of operation, from 07:00 to 23:00.
The departing passengers (one of the most relevant operational profiles) will access the front-end of the application to check in for their flight. It is known that 30% of departing passengers reconnect after checking in to request the boarding pass to be resent or printed.
Question
Assuming there is one boarding every 5 minutes, what should be the minimum front-end processing capacity of the system for the "departing passenger* user? It is assumed that there will be 12 peaks or maximums per hour.
SELECT ONE OPTION

  • A. 100 * 12 + (60 -12) * (10.42 - 4.69) = 1.475.04 transactions/hour
  • B. 100 * 12 + (60-12) *4.69 = 1,425.12 transactlons/hour
  • C. 100 * 12 + (60 -12) * 15.10 = 1,924.80 transactions/hour
  • D. 100 * 12 + (60 -12) * 10.42 = 1.700.16 transactions/hour

Answer: D

Explanation:
To calculate the minimum front-end processing capacity, we need to account for the peak and off-peak transactions:
1. Peak Transactions:
o Assume 12 peak periods per hour.
o During peak times, the transaction rate is 100 transactions/minute.
2. Off-Peak Transactions:
o There are 60 - 12 = 48 minutes of off-peak periods per hour.
o Off-peak transaction rate is 10.42 transactions/minute.
3. Total Transactions Per Hour:
o Peak transactions: 12 * 100 = 1,200 transactions.
o Off-peak transactions: 48 * 10.42 = 500.16 transactions.
o Total transactions per hour: 1,200 + 500.16 = 1,700.16 transactions/hour.
Thus, the correct answer is D. 100 * 12 + (60 - 12) * 10.42 = 1,700.16 transactions/hour.

3. Failures related to the correct configuration of features such as distribution, virtualization and scaling, during the Initial configuration or subsequent updates.
4. Inadequate bandwidth or capacity on any individual server.
SELECT ONE OPTION

  • A. 1C-2A-3D-4B.
  • B. 1A-2C-3D-4B.
  • C. 1D-2A-3C-4B
  • D. 1C - 2B - 3D - 4A.

Answer: A

Explanation:
