3.2 Define the AWS global infrastructure.
Objective 3.2 sits in Cloud Technology and Services, which carries 34% 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 creates a DB instance in eu-west-1 and expects to see it listed in us-east-1. Why does it not appear there?
The concept
Geographic separation only buys fault isolation if the boundary is real. A provider that quietly synchronises state between sites has sold you one large failure domain wearing several names.
Why this answer
Resources belong to the Region they were created in and are not copied elsewhere unless you arrange it. A list call runs against whichever Region you are pointed at and returns only what lives there.
- AThe console reads the same regional endpoint the CLI does. Refreshing will not surface something that was never created in that Region.
- Correct. Each AWS Region is designed to be isolated from the other AWS Regions, and resources are not automatically replicated across them.
- CProvisioning time affects status, not location. The instance would show as creating in its own Region long before it finished.
- DPermissions decide what you may do in a Region. They never merge two Regions into a single view of your inventory.

Sample question 2 of 3

Sample question 3 of 3
A hospital must keep patient processing inside its own building but wants the same AWS APIs it already uses in the Region. Which option fits?
That’s 3 of the full Cloud Practitioner bank.
