iSQI CTFL-PT_D Exam - Topic 5 Question 21 Discussion

Actual exam question for iSQI's CTFL-PT_D exam

Question #: 21
Topic #: 5

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 Suggested Answer

Suggested Answer: A

The correct associations between the aspects and factors to be considered when selecting performance testing tools are:

1. Compatibility: Protocols. (C)

2. Scalability: Ability to generate load from multiple points of presence. (D)

3. Understandability: Level of technical knowledge needed to use the tool. (A)

4. Monitoring: Correlation of the monitoring with the defined transactions. (B)

I agree with A, we need to handle those peak times effectively.

Option B feels too low, we need to aim higher for performance!

Wait, 2,000 concurrent users? That sounds a bit too high!

Option A seems solid, 6,000 users is a good target.

I keep thinking about the response times we studied, and option C seems off because it mentions a different number of users than what we need for check-in.

I practiced a similar question where we had to determine user capacity, and I think option B doesn't really fit since it limits the number of flights.

I'm not entirely sure, but I feel like option A might be too high for the peak users mentioned in the scenario.

I remember we discussed performance objectives in class, and I think option D aligns with the requirement of a three-second completion time.

This is a tricky one. The scenario gives a lot of specific details, and I want to make sure I'm interpreting them correctly. I think I'll start by identifying the key performance requirements, like the 3-second time constraint and the peak user load, and then see which option best matches those.

Option D looks promising - it mentions a 3-second completion time for 2,000 concurrent users, which seems to align with the requirements in the scenario. I'll double-check the other options, but this one seems like a good fit.

Hmm, I'm a bit confused by the details in this question. It mentions a 3-second time constraint for 90% of transactions, but the options seem to have different performance targets. I'll need to carefully read through the details to make sure I understand the requirements before selecting an answer.

This question is asking for a performance-related business objective, so I need to focus on things like scalability, response time, and throughput. Option A seems to address the peak concurrent users and performance degradation, which is relevant.

Option B? Really? 1,000 users? That's like a tiny airline. This is a major international carrier we're talking about here!

I'm going with Option C. One second response time for boarding pass issuance is a reasonable and achievable goal.

Option A seems the most relevant to the performance requirements stated in the scenario. The system needs to handle peak concurrent users efficiently.
