1.1 Define the benefits of the AWS Cloud.
Objective 1.1 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.
Demand on an internal app peaks midweek and is low the rest of the week, but the team runs enough servers for the peak every day. What does adding EC2 Auto Scaling change?
The concept
Capacity fixed at the peak sits idle most of the time, and capacity fixed at the average breaks under load. Renting by the hour removes that choice.
Why this answer
Scaling policies add servers as demand climbs and remove them as it falls, so you pay for peak-sized capacity only for the hours the peak actually exists.
- AReserved Instances and Savings Plans lower the rate, but the extra servers still run all week and stay idle on the quiet days.
- Correct. New instances are added only when necessary and terminated when they are no longer needed, so the midweek peak costs money while it lasts.
- CLoad balancing shares requests between healthy instances. It answers how work is distributed, not how many servers exist at 3am on Sunday.
- DNo AWS discount applies to an unused instance. Billing counts the hours an instance runs, whatever its CPU is doing.

Sample question 1 of 3
What does CloudFront use to deliver a file to a viewer with the lowest possible latency?
Sample question 2 of 3
A team runs an Auto Scaling group in one Availability Zone. What do they gain by adding two more zones to the group?
Sample question 3 of 3
A team asks why their on-premises platform keeps falling over under load spikes while the AWS version does not. Which cause does AWS name?
