Question No. 1

What is the benefit of transaction nesting for performance testing?

SELECT ONE OPTION

AThe possibility to measure the evolution of response time with the load.

BThe ability to measure individual and aggregate activities.

CThe possibility to measure the time elapsed for the transaction.

DThe ability to measure reflection time to better represent when a real user performs an action.

Show Answer

Correct Answer: B

Transaction nesting allows performance testers to measure both individual activities within a transaction and the aggregate performance of the entire transaction. This is beneficial because it helps identify specific areas where performance issues may be occurring. By understanding both the granular and overall performance, testers can better pinpoint bottlenecks and optimize the system. This aligns with the ISTQB principles of comprehensive performance measurement and analysis to ensure system reliability and efficiency.

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

A1C-2D-3A-4B.

B1B-2D-3A-4C.

C1D-2C-3A-4B.

Question No. 3

(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

A625.00 departing passengers / hour.

B1,425.00 departing passengers / hour

C1,700 00 departing passengers / hour.

D812.50 departing passengers / hour.

Show Answer

Correct Answer: A

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.

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

Choose the ONE option that describes the example of a transaction. The scenario for this question is the transfer of an amount of money from one bank account to another.

SELECT ONE OPTION

ARequest transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; Increase the balance of account P by X Monetary Units. If the reduction and Increase have been correctly applied, then apply changes.

BRequest transfer of X Monetary Units from account K to account P; increase the balance of account P by X Monetary Units. If the increase in account P has been correctly applied, then apply changes.

CRequest transfer of X Monetary Units from account K to account P; decrease the balance of account K by X Monetary Units. If the reduction in account K has been correctly applied, then apply changes.

DRequest transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; increase the balance of account P by X Monetary Units. If the reduction or increase has been correctly applied, then apply changes

Show Answer

Correct Answer: D

A transaction in performance testing involves a series of actions that need to be completed to ensure data consistency and correctness. Option D captures the complete and atomic nature of a transaction by ensuring that both the reduction in account K and the increase in account P are correctly applied before committing the changes. This reflects the principles of ACID (Atomicity, Consistency, Isolation, Durability) in database transactions, which are crucial for ensuring reliability and correctness in financial operations as covered in ISTQB performance testing standards.
