最新的 Performance Testing CTFL-PT_D 免費考試真題 (Q36-Q41):

問題 #36
Choose the VALID description of the ramp-up concept.
SELECT ONE OPTION

  • A. Stage of finishing the test.
  • B. Stage of exit from a stationary state by increasing the number of concurrent users.
  • C. Stage of reaching the stationary state.
  • D. Technique in which the load on the system is increased to a certain value in the shortest possible time.

答案:B

解題說明:
Ramp-up in performance testing refers to the phase where the number of virtual users is gradually increased to simulate the increase in load on the system. This is essential for determining how the system behaves under varying levels of stress. The correct description of the ramp-up concept aligns with option C, which involves increasing the number of concurrent users to simulate a transition from a steady state to a higher load scenario.

問題 #37
Identify the correspondences between the aspects (listed from 1 to 4) and factors to be considered (listed from A to D) when selecting performance testing tools.
1. Compatibility.
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. 1C-2D-3A-4B.
  • D. 1B-2D-3A-4C.

答案:C

解題說明:
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
* ISTQB Glossary


問題 #38
In this question, consider that test scripts are generated from a protocol level recording. At the end of the recording, an attempt was made to execute the recorded scripts without any processing, and it was not possible to play them back.
Question
What could be the reason why it is not possible to play back the script?
SELECT ONE OPTION

  • A. The length of the script.
  • B. The lack of business logic.
  • C. The missing Initialization section.
  • D. The test script has not been correlated.

答案:D


問題 #39
Choose the option that BEST describes valid opportunities for the dynamic performance testing.
SELECT ONE OPTION

  • A. During component Integration testing, across any kind of use cases and workflows, especially when integrating different use case features or Integrating with the "backbone" structure of a workflow.
  • B. During acceptance testing, especially for data flows and workflows across key inter-system interfaces. In system integration testing, it is not uncommon for the "user* to be another system or machine (e.g. inputs from sensor inputs and other systems).
  • C. During unit testing, including using or not profiling information to determine potential bottlenecks and white box techniques to evaluate resource utilization.
  • D. During system testing of overall end-to-end behaviors under various load conditions.

答案:D

解題說明:
System testing of overall end-to-end behaviors under various load conditions provides a comprehensive view of how the system performs in real-world scenarios. This type of testing captures interactions between components, identifies potential bottlenecks, and ensures that the system meets performance requirements under expected load conditions. ISTQB performance testing principles highlight the importance of end-to-end testing to validate that the system can handle the intended workloads effectively.


問題 #40
If a performance test is testing the response time of an application to be connected through remote access, which protocol is being used?
SELECT ONE OPTION

  • A. RTE.
  • B. WSCL.
  • C. LDAP.
  • D. MMS.

答案:A

解題說明:
RTE (Remote Terminal Emulation) protocol is used when testing the response time of an application connected through remote access. It simulates interactions with applications over a network as if they were being accessed locally, making it suitable for remote access scenarios.
