Question No. 2

Base Scenario 1: This Base Scenario 1 is used for 2 questions throughout this exam. When you refer to Base Scenario 1, you are referring to this description and only this description, without any modification.

k given project for the development of a management software that will have a multilayer architecture will enable Its users to Install it in multiple locations, nationally and internationally - each installation can operate Independently and communicate with other instances in a selective way. Each installation shall have a high processing capacity.

Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).

* The project follows a sequential development life cycle model.

Question

Which is the right moment in the project to analyze and evaluate the performance risks?

SELECT ONE OPTION

AAfter design but before coding.

BDuring the requirements activities and again before running the performance test.

CDuring the analysis and design activities as well as, again, before each performance test cycle.

DRepeatedly throughout the development phases (including requirements activities) and the performance test itself.

Show Answer

Correct Answer: D

Performance risks should be analyzed and evaluated continuously throughout the development lifecycle, especially in projects with high processing capacity and independent operation across multiple locations. This ongoing evaluation helps to identify and mitigate risks early and adapt to any changes that occur during development.

Question No. 3

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

ATrue statements: IV.

BTrue statements: III, IV.

CTrue statements: II, III.

DTrue statements: I, III.

Show Answer

Correct Answer: B

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.

Question No. 4

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

Show Answer

Correct Answer: A

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.

Question No. 5

(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

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.

BThe 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.

CA 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.

DA 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.

Show Answer

Correct Answer: C

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.
