ISQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing Sample Questions (Q22-Q27):

NEW QUESTION # 22
(REFER TO BASE SCENARIO 2): IV/rerj 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
A performance test will be carried out for which 11,700 transactions will be necessary to simulate an operation similar to that described in the base scenario and the restrictions of this question. How many virtual users will be necessary to achieve this number of transactions and the conditions of the operations?
SELECT ONE OPTION

  • A. 8,500
  • B. 9,000
  • C. 23,400
  • D. 11,700

Answer: D

Explanation:
To determine the number of virtual users necessary for the performance test:
1. Total Transactions Needed:
o 11,700 transactions are required to simulate the operation.
2. Conditions of Operations:
o The simulation should reflect the realistic load of departing passengers accessing the front-end application.
3. Virtual Users:
o The number of virtual users required is equal to the total number of transactions to be generated in the test since each virtual user performs one transaction.
Thus, the correct answer is B. 11,700 virtual users will be necessary to achieve the specified number of transactions under the given conditions.


NEW QUESTION # 23
(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).
Natalie has run a performance test cycle. The following metrics have been collected:
Total virtual users: 10,000.
* Status of the simulated users.
o Total number of users for whom all transactions have been completed: 89%.
* Transaction response time, o Check-in
* Response time < 1 second: 60%
* Response time < 2 seconds: 70%
* Response time < 3 seconds: 88%
* Response time < 5 seconds: 90%
* Response time < 10 seconds: 95%
Question
Given this information, how should Natalie present the results to those involved?
SELECT ONE OPTION

  • A. The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check-in are close to the acceptance value, no Improvement is required.
  • B. The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check in are below the acceptance value, an improvement is required.
  • C. The percentage of completed transactions is so close to the acceptance value that no improvement is required. The transactions associated with the check-in are below the acceptance value, a minimum improvement is required.
  • D. The percentage of completed transactions is close to the acceptance value, no improvement is required. The transactions associated with the check-in are below the acceptance value, no improvement is required.

Answer: B

Explanation:
When presenting performance test results, it is vital to compare the collected metrics against the predefined acceptance criteria and highlight areas needing improvement.
* Option A incorrectly suggests that no improvement is required for completed transactions, even though the acceptance value isn't met.
* Option B rightly states that improvements are required for completed transactions but incorrectly suggests no improvement is needed for check-in transactions.
* Option C suggests no improvements are needed for either metric, which is incorrect as both are below the acceptance values.
* Option D correctly identifies that both the percentage of completed transactions and the check-in transactions are below the acceptance values and require improvement.
Therefore, Option D accurately reflects the need for improvements in both metrics to meet the acceptance criteria.


NEW QUESTION # 24
Choose the ONE option that describes the example of a transaction. The scenario for this question is the transfer of an amount of money from one bank account to another.
SELECT ONE OPTION

  • A. Request transfer of X Monetary Units from account K to account P; decrease the balance of account K by X Monetary Units. If the reduction in account K has been correctly applied, then apply changes.
  • B. Request transfer of X Monetary Units from account K to account P; increase the balance of account P by X Monetary Units. If the increase in account P has been correctly applied, then apply changes.
  • C. Request transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; Increase the balance of account P by X Monetary Units. If the reduction and Increase have been correctly applied, then apply changes.
  • D. Request transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; increase the balance of account P by X Monetary Units. If the reduction or increase has been correctly applied, then apply changes

Answer: D

Explanation:
A transaction in performance testing involves a series of actions that need to be completed to ensure data consistency and correctness. Option D captures the complete and atomic nature of a transaction by ensuring that both the reduction in account K and the increase in account P are correctly applied before committing the changes. This reflects the principles of ACID (Atomicity, Consistency, Isolation, Durability) in database transactions, which are crucial for ensuring reliability and correctness in financial operations as covered in ISTQB performance testing standards.


NEW QUESTION # 25
(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
How many departing passengers access the front-end only once to check in per hour?
SELECT ONE OPTION

  • A. 1,218.75 departing passengers / hour.
  • B. 187.50 departing passengers / hour
  • C. 812.50 departing passengers / hour.
  • D. 625.00 departing passengers / hour.

Answer: D

Explanation:
To calculate the number of departing passengers accessing the front-end only once to check in per hour, we follow these steps:
1. Total Departing Passengers in January:
o 465,000 passengers transported throughout January.
2. Duration of Operations in January:
o Operating hours: 07:00 to 23:00, which equals 16 hours per day.
o Total days in January: 31 days.
o Total operating hours in January: 31 days * 16 hours/day = 496 hours.
3. Passengers Per Hour:
o Total passengers: 465,000.
o Total hours of operation: 496 hours.
o Passengers per hour: 465,000 passengers / 496 hours = 937.5 passengers/hour.
4. Passengers Accessing Only Once for Check-In:
o 30% of departing passengers reconnect for a boarding pass, which means 70% access only once.
o Passengers accessing only once: 70% of 937.5 passengers/hour = 0.70 * 937.5 = 656.25 passengers/hour.
Given the available options, the closest correct value is C. 625.00 departing passengers / hour.


NEW QUESTION # 26
Which ONE of the following mechanisms is used to make the load test represent a load situation in a real production environment?
SELECT ONE OPTION

  • A. Configure environments with multiple points of presence.
  • B. Generate load through the Application Programming Interface (API).
  • C. Generate load through the User Interface.
  • D. Gradually restrict system resources during the load test.

Answer: C

Explanation:
Generating load through the User Interface (UI) is essential to replicate a real production environment accurately. This approach simulates real user interactions with the system, providing a more realistic assessment of how the system performs under actual usage conditions. According to ISTQB standards, using the UI to generate load helps identify performance issues that users might experience, ensuring that the test results are relevant and actionable.
