iSQI CTFL-PT_D Exam - Topic 1 Question 20 Discussion

Actual exam question for iSQI's CTFL-PT_D exam

Question #: 20
Topic #: 1

(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.

SELECT ONE OPTION

A100 * 12 + (60-12) *4.69 = 1,425.12 transactlons/hour

B100 12 + (60 -12) * (10.42 - 4.69) = 1.475.04 transactions/hour

C100 * 12 + (60 -12) * 15.10 = 1,924.80 transactions/hour

D100 * 12 + (60 -12) * 10.42 = 1.700.16 transactions/hour

Show Suggested Answer

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.

I think option D makes the most sense.

Are we sure about those transaction numbers? Feels off.

I recall that we need to account for the boarding every 5 minutes, which gives us a specific number of transactions. I think I lean towards option A, but I’m not entirely confident.

I’m confused about the 30% of passengers reconnecting. Does that factor into the total transactions, or is it just for the boarding pass requests?

I think we practiced a similar question where we had to calculate processing capacity based on peak times. I feel like option D might be the right choice, but I need to double-check my calculations.

I remember we discussed the peak hours and how to calculate the transactions per hour, but I'm a bit unsure about the exact formula to use here.

This seems straightforward enough. I'll just plug the numbers into the formula and select the corresponding option. As long as I don't make any silly mistakes, I should be able to nail this one.

I'm a bit confused by the different options provided. I'll need to work through the calculations carefully to make sure I select the right answer. Glad I have some time to really think this through.

I think I've got this. The key is to calculate the peak transactions per hour and then add in the additional reconnections. Time to put my math skills to the test!

Okay, let me break this down step-by-step. We have the total number of departures, the hours of operation, and the percentage of passengers who need to reconnect. Now I just need to figure out the right formula to calculate the minimum front-end processing capacity.

Hmm, this looks like a tricky one. I'll need to carefully read through the details and make sure I understand all the constraints before attempting to solve it.

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.
