Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
An SCP that denies ec2:RunInstances when the instance type is not t2.micro.
An SCP that denies ec2:RunInstances when the instance type is not t2.micro will prevent launching any instance type other than t2.micro. SCPs are centralized and can be applied to OUs. Option A is incorrect because IAM policies are per-account and not centralized. Option B is incorrect because an allow SCP by itself would only allow t2.micro but would not prevent other instance types unless the default is to deny all, which is not the case. Option D is incorrect because AWS Config rules are reactive and do not prevent actions; they only detect and can remediate after the fact.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An IAM policy applied to each account's admin role to restrict instance types.

IAM policies are not centralized across accounts.
- ✗
An SCP that allows ec2:RunInstances only for t2.micro.

- ✓
An SCP that denies ec2:RunInstances when the instance type is not t2.micro.
