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
✓
The root user is being used to perform administrative actions.
The event shows the AWS root user creating a security group. Best practice is to not use root for daily tasks. The source IP is external, but that is not necessarily a concern. The security group name is not the issue. The region is us-east-1, not a concern.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The root user is being used to perform administrative actions.
Why this is correct
Root user should not be used for daily operations; IAM users should be used.

The security group was created with a permissive name.
Why it's wrong here
The name is not a security concern.
- ✗
The event took place in a region that is not used by the company.
Why it's wrong here
There is no indication the region is not used.
- ✗
The event originated from an external IP address.
Why it's wrong here
External IP could be expected if accessing via console.
