[All CTFL-PT_D Questions]

(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

Assuming there is one boarding every 5 minutes, what should be the minimum front-end processing capacity of the system for the "departing passenger* user? It is assumed that there will be 12 peaks or maximums per hour.

Suggested Answer: C

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.

Okay, let's break this down step-by-step. 3,100 departure operations, 465,000 passengers, 30% reconnecting after check-in. Gotta find the peak hourly transactions.

After that, we can find the total number of transactions per hour by considering the boarding rate of one every 5 minutes and the 12 peaks per hour.

Then we need to calculate the number of passengers who will reconnect after check-in, which is 30% of 465,000.

Hmm, looks like a lot of math involved here. The question is asking for the minimum front-end processing capacity, so I'll focus on the calculations.
