- A
Disable AWS CloudTrail to reduce costs
Why wrong: CloudTrail is essential for auditing.
- B
Disable password rotation to avoid user inconvenience
Why wrong: Password rotation is a security best practice.
- C
Use the root user for daily administrative tasks
Why wrong: Root user should be reserved for limited tasks.
- D
Enable multi-factor authentication (MFA) for privileged users
MFA adds an extra layer of security.
- E
Use IAM roles for applications that run on EC2 instances
IAM roles provide temporary credentials and are secure.

DVA-C02 Multi-Factor Authentication (MFA) Practice Question
This DVA-C02 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: multi-Factor Authentication (MFA).

Correct answer & explanation
✓
Enable multi-factor authentication (MFA) for privileged users
The best practices for securing an AWS account include enabling multi-factor authentication (MFA) for privileged users (Option D) and using IAM roles for applications that run on EC2 instances (Option E). Option A is incorrect because disabling CloudTrail reduces visibility into API activity, which is a security risk. Option B is incorrect because disabling password rotation weakens security posture. Option C is incorrect because the root user should be reserved for a limited set of tasks and not used daily.

Key takeaway
Multi-Factor Authentication (MFA)
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
