iSQI CTFL-AT Exam - Topic 1 Question 3 Discussion

Actual exam question for iSQI's CTFL-AT exam

Question #: 3
Topic #: 1

Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:

"As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car:

* If the power of the vehicle is less than 20 kW, then the annual car tax is free

* If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros

* If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros"

What is the MOST suitable use of a black-box test design technique for this user story?

ADecision table testing. Test the following conditions:
Conditions=registered user logged in; inserted power of the vehicle=20kW;
Action=Car tax paid

BState transition testing. Test the transitions between the following states:
logging in, inserting the power of the vehicle, making payment, logging out.

CEquivalence partitioning. Test the annual car tax value for the following partitions:
[power of the vehicle<20 kW ; 20 kW power of the vehicles150 kW; power of the vehicle>150 kW]

DUse case testing
Test the following use case (Actor=registered user):
Pre-condition=registered user logged in
Scenario=registered user inserts the power of the vehicle, making payment and logs out
Post-condition=car tax paid and registered user logged out

Not sure if equivalence partitioning covers all edge cases properly.

Wait, does anyone actually have a car under 20 kW?

Decision table testing seems too limited for this scenario.

The tax is free for vehicles under 20 kW!

Use case testing could work, but I feel like it might be too broad for just focusing on the tax calculation part.

State transition testing sounds relevant, but I wonder if it really captures the tax calculation logic as well as the other options.

I remember practicing with equivalence partitioning, and it seems like a good fit for testing the different power ranges for the car tax.

I think decision table testing might be useful here, but I'm not entirely sure if it covers all the conditions effectively.

I'm a bit unsure about this one. There are a few different codes that could potentially apply. I'll need to double-check my notes to make sure I select the right option.

I feel like SSL 2.0 is really outdated and probably the least secure. Did we cover that in our last practice exam?

Okay, I've got this. Service profiles can definitely have different capabilities assigned to different custodians, so the answer must be True.

High availability seems like the obvious choice here. Azure's SLA and redundancy features are designed to prevent single points of failure and keep services running even with hardware or network issues.
