ISQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing Sample Questions (Q18-Q23):

NEW QUESTION # 18
Select the ONE option that describes the mechanism used to extract metrics associated with deadlocks and multi threading problems SELECT ONE OPTION

  • A. Direct measurement through a performance monitoring tool.
  • B. Scan server logs and compile metrics from them.
  • C. Analysis and elaboration of metrics from a dynamic performance test.
  • D. Direct measurement from a dynamic performance test.

Answer: A

Explanation:
Direct measurement through a performance monitoring tool is the most effective mechanism for extracting metrics associated with deadlocks and multithreading problems. These tools can provide real-time insights into the system's performance, highlighting issues such as thread contention, deadlocks, and resource bottlenecks. ISTQB performance testing principles advocate the use of specialized monitoring tools to capture detailed performance metrics, facilitating the identification and resolution of complex multithreading issues.


NEW QUESTION # 19
Refer to Base Scenario 1: When you refer to Base Scenario 1, 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).
* The project follows an iterative and Incremental development life cycle model.
* Development approach: Agile.
Question
Which of the statement(s) below is (are) TRUE regarding how the performance test is undertaken7
1. The performance test can have a dedicated iteration in a specific way.
2. Performance testing should be performed in a cloud-based performance test environment
3. The performance test may be conducted by a specific team.
4. A performance test cycle must be performed in each iteration by the development team (Agile).
SELECT ONE OPTION

  • A. True statements: II, III.
  • B. True statements: I, III.
  • C. True statements: III, IV.
  • D. True statements: IV.

Answer: C

Explanation:
In an Agile, iterative, and incremental development model:
* III: The performance test may be conducted by a specific team. This is true as dedicated performance testing teams often handle complex performance testing tasks.
* IV: A performance test cycle must be performed in each iteration by the development team (Agile). This ensures that performance testing is integrated into each iteration to catch performance issues early.
Statements I and II are not necessarily true:
* I: While possible, it is not always the case that there will be a dedicated iteration for performance testing.
* II: Performance testing in a cloud-based environment is beneficial but not mandatory.
Reference:
* ISTQB Performance Testing Syllabus
* ISTQB Agile Tester Extension Syllabus


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).
* Natalie should make a presentation to the business stakeholders In order to explain the performance test plan.
Question
Which ONE of the following options contains information that should be included in Natalie's presentation to the business stakeholders?
SELECT ONE OPTION

  • A. The cost of the spike test will be in line with the budget submitted by the cloud service provider. The test must take place in the planned timeframe and use the disassociation algorithm, that were previously agreed on.
  • B. A spike test shall be conducted in a test environment equivalent to the production environment. Passengers shall be removed from the production environment, disassociated and imported Into the test environment.
  • C. A performance test will be conducted to verify the management applications capability to support simultaneous, i.e concurrent, request peaks. The objective of this test (spike test) is to check that the system will be able to support the operations.
  • D. A spike test shall be conducted in the performance test environment set up by the systems manager. Preparation includes installation from the clone of the virtual machine identified for this purpose.

Answer: C

Explanation:
When preparing a presentation for business stakeholders, it is essential to focus on high-level objectives and outcomes that align with business goals. In the context of performance testing, the stakeholders are primarily concerned with ensuring that the system can handle peak loads and maintain operational integrity.
* Option A talks about the setup of the test environment and the logistics of passenger data, which is too technical for business stakeholders.
* Option B focuses on budget and timeline, which are relevant but do not directly address the performance test's purpose and objectives.
* Option C clearly states the purpose of the performance test (spike test) and its objective, which is to verify that the system can support concurrent request peaks, directly aligning with business interests.
* Option D again focuses on technical details about the test environment setup, which is not the primary concern for business stakeholders.
Therefore, Option C is the most appropriate choice as it succinctly communicates the performance test's objective and its relevance to business operations.


NEW QUESTION # 21
(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 per hour?
SELECT ONE OPTION

  • A. 625.00 departing passengers / hour.
  • B. 812.50 departing passengers / hour.
  • C. 1,425.00 departing passengers / hour
  • D. 1,700 00 departing passengers / hour.

Answer: A

Explanation:
To determine how many departing passengers access the front-end per hour, including those reconnecting:
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. Including Reconnecting Passengers:
o 30% of departing passengers reconnect for a boarding pass.
o Reconnecting passengers: 30% of 937.5 passengers/hour = 0.30 * 937.5 = 281.25 passengers/hour.
o Total front-end accesses per hour: 937.5 + 281.25 = 1,218.75 passengers/hour.
Given the available options, the closest correct value is A. 1,425.00 departing passengers / hour.


NEW QUESTION # 22
Which elements are the MOST important parts of a performance testing environment?
1. Test scripts.
2. Software configuration.
3. Test data.
4. The type of environment (physical, cloud-based, virtualized).
5. Hardware configuration.
SELECT ONE OPTION

  • A. III, V are the most important parts of the test environment.
  • B. II. IV are the most important parts of the test environment.
  • C. II. III. V are the most important parts of the test environment.
  • D. II, V are the most important parts of the test environment.

Answer: C

Explanation:
* II. Software configuration: Ensures the software under test is set up correctly, mirroring the production environment as closely as possible.
* III. Test data: Provides the necessary inputs to simulate real-world scenarios and workloads.
* V. Hardware configuration: Ensures the physical resources are adequately represented to gauge performance metrics accurately.
These elements are crucial for creating a realistic and effective performance testing environment. According to ISTQB standards, these components ensure that the testing environment accurately reflects production conditions, which is critical for obtaining valid and reliable performance test results.
