What are the prerequisites for taking the CTFL-PT_D exam?

Candidates must hold a valid ISTQB Certified Tester Foundation Level (CTFL) certification before attempting the CTFL-PT_D specialist exam. There is no mandatory training requirement, but iSQI recommends candidates have practical experience in performance testing and familiarity with performance testing tools and concepts.

How long is the CTFL-PT_D exam and how many questions does it contain?

The CTFL-PT_D exam is 90 minutes long and consists of 40 questions in multiple-choice format. Each question is worth equal points, and candidates need to achieve a minimum score of 65% to pass the certification.

What topics are covered in the CTFL-PT_D certification exam?

The exam covers performance testing fundamentals including test types, performance objectives, planning, design, execution, and analysis of performance tests. It also includes knowledge of performance testing tools, metrics, reporting, and best practices in performance testing within an Agile environment.

Is the CTFL-PT_D certification valid indefinitely or does it need to be renewed?

The CTFL-PT_D certification is valid for three years from the date of passing the exam. After three years, holders must renew their certification by passing the exam again or through other renewal methods established by ISTQB and iSQI.

What is the difference between CTFL-PT_D and the general CTFL certification?

The CTFL-PT_D is a specialist level certification that focuses specifically on performance testing and requires a foundational CTFL certification as a prerequisite. The general CTFL covers broader software testing fundamentals, while CTFL-PT_D provides advanced knowledge in performance testing methodologies, tools, and practices.

Q1 MultipleChoice

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

AMMS.

BRTE.

CWSCL.

DLDAP.

Correct Answer: B

Explanation:

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.

Q2 MultipleChoice

(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 technical 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 technical stakeholders?

SELECT ONE OPTION

AA 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.

BA 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.

CThe cost of the spike test will be In line with the budget submitted by the cloud service provider. The test must take place within the planned timeframe and use the disassociation algorithm previously agreed.

DA performance test will be conducted to verify the management application s capability to support simultaneous, i.e. concurrent, request peaks. The objective is to check that the system will be able to support the operations.

Correct Answer: B

Explanation:

When presenting to technical stakeholders, it is crucial to provide detailed information about the setup, preparation, and execution of the performance test.

* Option A talks about the test environment and passenger data logistics, which, while technical, is not as focused on the specific setup for the spike test.

* Option B details the specific environment setup by the systems manager and the preparation steps, which are highly relevant to technical stakeholders who will be involved in or overseeing the technical aspects of the test.

* Option C again focuses on budget and timeline, not technical details.

* Option D is more high-level about the purpose of the test, which is not as relevant for technical stakeholders who need the specifics of the test setup.

Thus, Option B is the best fit as it provides the necessary technical details for the spike test environment and preparation steps.

Q3 MultipleChoice

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

AThe 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.

BThe system must be able to support peak attendance of 1,000 users, considering that there cannot be more than two flights with overlapping schedules.

CThe 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.

DThe system must have a completion time of up to three seconds for 2,000 concurrent users for updating passenger check-in data

Correct Answer: A

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.

Q4 MultipleChoice

Select the ONE option that describes the mechanism used to extract metrics associated with deadlocks and multi threading problems

SELECT ONE OPTION

ADirect measurement from a dynamic performance test.

BAnalysis and elaboration of metrics from a dynamic performance test.

CDirect measurement through a performance monitoring tool.

DScan server logs and compile metrics from them.

Correct Answer: C

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.

Q5 MultipleChoice

ich ONE of the following options is a specific performance risk in mobile applications?

ONE OPTION

ANetwork congestion.

BSlow data flow from sensors.

CLimited resources.

DInefficient Implementation of algorithms.

Correct Answer: C

Explanation:

Mobile applications often face performance risks due to the limited resources available on mobile devices, such as CPU, memory, battery, and network bandwidth. These constraints can significantly impact the performance of mobile applications, leading to slower response times and degraded user experiences. ISTQB performance testing guidelines emphasize considering the specific resource limitations of mobile environments to ensure comprehensive performance evaluation and optimization.
