ISQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing Sample Questions (Q23-Q28):

NEW QUESTION # 23
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; increase the balance of account P by X Monetary Units. If the increase in account P has been correctly applied, then apply changes.
  • B. 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
  • C. 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.
  • 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 and Increase have been correctly applied, then apply changes.

Answer: B

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 # 24
Select the architecture that, in addition to the virtualized systems, could present performance risks associated with virtualization.
SELECT ONE OPTION

  • A. Client-server systems.
  • B. Dynamic/cloud-based systems.
  • C. Multi Tier systems.
  • D. Distributed systems.

Answer: B

Explanation:
Dynamic and cloud-based systems introduce performance risks associated with virtualization due to the inherent nature of resource allocation and scalability in these environments. Virtualized systems often share physical resources, leading to potential contention and unpredictable performance impacts. These risks are more pronounced in dynamic/cloud-based architectures where resources are frequently allocated and deallocated based on demand, potentially causing latency, resource bottlenecks, and performance variability. ISTQB guidelines on performance testing emphasize understanding these risks to ensure reliable performance outcomes.


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

Answer: A

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.


NEW QUESTION # 26
Identify the correspondences between the communication protocols used most frequently (listed from 1 to 5) in performance testing and the categories to which they belong to (A to C).
1.REST.
2. HTTP.
3. JDBC.
4. SOAP.
5. HTTPS.
1. Web service.
2. Database.
3. Web.
SELECT ONE OPTION

  • A. 1A-2B-3B-4C-5C.
  • B. 1A-2C-3A-4A- 5B.
  • C. 1A-2C-3B-4A-5C.
  • D. 1C - 2C - 3B - 4A - 5A.

Answer: C

Explanation:
* 1A: REST - Web service
* 2C: HTTP - Web
* 3B: JDBC - Database
* 4A: SOAP - Web service
* 5C: HTTPS - Web
This mapping accurately categorizes each protocol according to its common use in performance testing. REST and SOAP are typically used for web services, JDBC for database connectivity, and HTTP/HTTPS for web communications. Understanding these correspondences helps testers select the appropriate protocols for performance testing scenarios, as outlined in ISTQB guidelines.


NEW QUESTION # 27

2. Scalability.
3. Understandability.
4. Monitoring.
1. Level of technical knowledge needed to use the tool.
2. Correlation of the monitoring with the defined transactions.
3. Protocols.
4. Ability to generate load from multiple points of presence.
SELECT ONE OPTION

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

Answer: D

Explanation:
The correct associations between the aspects and factors to be considered when selecting performance testing tools are:
1. Compatibility: Protocols. (C)
2. Scalability: Ability to generate load from multiple points of presence. (D)
3. Understandability: Level of technical knowledge needed to use the tool. (A)
4. Monitoring: Correlation of the monitoring with the defined transactions. (B) Reference:
* ISTQB Performance Testing Syllabus
