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 only once to check in per hour?
SELECT ONE OPTION

• A.187.50 departing passengers / hour
• B.812.50 departing passengers / hour.
• C.1,218.75 departing passengers / hour.
• D.625.00 departing passengers / hour.

Identify the correspondences between architectures (from 1 to 4) and their characteristic risks (from A to D).
1. Dynamlc/cloud-based systems.
2. Client-server systems.
3. Multi-Tier systems.
4. Distributed systems.
1. Potential problems due to firewalls, packet inspection and server load balancing.
2. Critical workflows or dataflows to, from, or through unreliable or unpredictable remote servers, especially when such servers suffer periodic connection problems or intermittent periods of intense load.
3. Failures related to the correct configuration of features such as distribution, virtualization and scaling, during the Initial configuration or subsequent updates.
4. Inadequate bandwidth or capacity on any individual server.
SELECT ONE OPTION

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

Associate each type of performance test (listed from 1 to 5) with part of a description that allows its characterization and/or identification (listed from A to E).
1. Endurance testing
2. Scalability testing
3. Capacity testing
4. Stress testing
5. Concurrency testing
1. Type of testing focused on the ability of a system to meet future efficiency requirements.
2. Type of testing used to evaluate a system's ability to handle reduced availability of resources.
3. Type of testing focused on the stability of the system over a specific time frame.
4. Type of testing used to determine the number of transactions a given system will support while still meeting established performance objectives.
5. Type of testing focused on the impact of situations where specific actions occur simultaneously.
SELECT ONE OPTION

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

Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
Natalie has run a performance test cycle. The following metrics have been collected:
Total virtual users: 10,000.
* Status of the simulated users.
o Total number of users for whom all transactions have been completed: 89%.
* Transaction response time, o Check-in
* Response time < 1 second: 60%
* Response time < 2 seconds: 70%
* Response time < 3 seconds: 88%
* Response time < 5 seconds: 90%
* Response time < 10 seconds: 95%
Question
Given this information, how should Natalie present the results to those involved?
SELECT ONE OPTION

• A.The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check-in are close to the acceptance value, no Improvement is required.
• B.The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check in are below the acceptance value, an improvement is required.
• C.The percentage of completed transactions is close to the acceptance value, no improvement is required. The transactions associated with the check-in are below the acceptance value, no improvement is required.
• D.The percentage of completed transactions is so close to the acceptance value that no improvement is required. The transactions associated with the check-in are below the acceptance value, a minimum improvement is required.

Choose the MOST suitable description of the structure of a performance test script SELECT ONE OPTION

• A.The Initialization section Is the section in which everything Is prepared for the main part, the main sections are executed only once, because If It is necessary to repeat any action the whole script or part of it must be repeated and the clean-up section Is the section where the necessary steps are carried out to finish the test correctly.
• B.The initialization section Is the section in which everything Is prepared for the main part, the main sections can be executed several times and the finalization section is the section in charge of registering the results In the corresponding repository.
• C.The clean-up section Is the section in which everything is prepared for the main part In order to comply with the preconditions, the main sections can be executed several times and the completion section is the section that takes care of recording the results In the corresponding repository.
• D.The Initialization section is the section in which everything Is prepared for the main part, the main sections can be executed several times and the clean-up section is the section where the necessary steps are carried out to finish the test correctly.
