The answer is enabling multi-factor authentication (MFA) for the root user and using a strong password. These two measures directly protect the AWS root user because the root account has unrestricted access to all AWS resources and billing, making it the highest-value target for attackers. MFA adds a second layer of security beyond the password, while a strong, complex password resists brute-force or credential-stuffing attacks. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this concept tests your understanding of the AWS shared responsibility model and the principle of least privilege—specifically that the root user should never be used for daily tasks, only for a limited set of account-level actions. A common trap is confusing “creating an access key for the root user” with a security measure; in reality, AWS strongly discourages root access keys because they cannot be rotated or scoped. Memory tip: think “MFA + strong password = root user fortress,” and remember that any other action, like delegating tasks to IAM users, reduces root usage but is not a direct protective measure for the root account itself.
SOA-C02 Security and Compliance Practice Question
This SOA-C02 practice question tests your understanding of security and compliance. 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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO measures help protect an AWS account root user? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a strong, complex password for the root user.
Options A and B are correct. Enabling MFA and using a strong password are basic security measures for the root user. Option C is wrong because creating an access key for the root user is not recommended. Option D is wrong because using root user regularly is not a security measure. Option E is wrong because delegating admin tasks to IAM users reduces root user usage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use the root user regularly for administrative tasks.
Why it's wrong here
Root user should be used only for limited tasks; daily use increases risk.
✗
Create an access key for the root user for programmatic access.
Why it's wrong here
Access keys for root user are discouraged because they cannot be restricted.
✗
Grant other IAM users full administrator access.
Why it's wrong here
This is a best practice to avoid root user usage, but it is not a direct measure for protecting root user.
✓
Use a strong, complex password for the root user.
Why this is correct
A strong password reduces the risk of unauthorized access.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
