AWS account quiz · Level 0 · Todo.io Learns AWS

Question 1Why does Todo.io put Prod and Dev in separate AWS accounts rather than in one account?

An account is the strongest isolation boundary in AWS. Nothing in Dev can touch Prod unless it is explicitly allowed.Correct. A mistake, a leaked key or a runaway script in Dev stays in Dev. Separate accounts also give separate bills and quotas.Separate accounts are cheaper than one.Not this one. Accounts are free, but splitting doesn't lower the price of what runs in them.One account can only hold one VPC.Not this one. An account can have several VPCs in every Region.IAM can't tell Prod and Dev resources apart in one account.Not this one. It can, with careful policies, but it's easy to get wrong. The account boundary is far simpler and stronger.

Question 2What does "AWS account" mean?

A container for AWS resources, with its own identities and its own bill.Correct. Think of it as: A flat in an apartment building. Separate locks, separate meter.The identity you sign in as with the account's email address. It can do almost anything; only an SCP can limit it.Not this one. That describes Root user.A second proof of identity, like a code from an app or a security key, on top of a password.Not this one. That describes MFA (multi-factor authentication).Groups many AWS accounts under one management account, with one bill and shared guardrails.Not this one. That describes AWS Organizations.
