Objective 1.4 sits in Cloud Concepts, which carries 24% of the Cloud Practitioner exam. The questions below are original, written from the official objective title above, and each explanation cites the AWS page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team's development and test environments run around the clock but are used only during business hours on weekdays. Which cost optimization principle applies?
The concept
Paying by the hour only helps if you switch things off. The saving is not automatic, it comes from matching how long a resource runs to how long anyone needs it.
Why this answer
Stopping non-production resources outside working hours takes 168 paid hours a week down to 40, which is roughly three quarters off the bill for those environments.
- ACloud financial management is the organisational capability: the people, programmes and processes. It is the wrapper around a decision like this one.
- Correct. AWS puts the saving from stopping development and test resources when they are not in use at around 75 percent.
- CMeasuring efficiency compares business output against delivery cost. It would tell you the schedule worked, once you had set one.
- DAttributing expenditure tells you whose budget these environments land in. Knowing the owner does not switch anything off.

Sample question 1 of 3
A team asks what stopping spend on undifferentiated heavy lifting means in practice. What does AWS take on there?
Sample question 2 of 3
A team needs a cost estimate for a design that has not been built yet, to take to the budget owner. Which tool gives that?
Sample question 3 of 3
A finance team's review finds EC2 instances sitting at 4 percent CPU for months. Which service recommends a smaller instance from that utilisation history?
That’s 3 of the full Cloud Practitioner bank.
