This SOA-C02 practice question tests your understanding of security and compliance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 THREE security best practices should be followed when managing IAM users? (Choose three.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Attach policies directly to users
Why wrong: Policies should be attached to groups or roles for easier management.
Rotate access keys regularly
Limits exposure of compromised keys.
Use the root user for daily administration
Why wrong: Root user should be used only for account-level tasks.
Grant least privilege permissions
Minimizes potential impact of compromised credentials.
Enable MFA for all users
Adds an extra layer of security.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Rotate access keys regularly
Granting least privilege, enabling MFA, and rotating access keys regularly are key security best practices. Option A, Option B, and Option D are correct. Option C is wrong because using the root user for daily tasks is a security risk. Option E is wrong because IAM policies should be attached to groups or roles, not directly to users, to simplify management.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
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.
What to study next
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SOA-C02 questions on access control and AAA configuration.
