Quick Answer
The answer is authentication. In the AAA framework, authentication is the component responsible for verifying a user’s identity, and requiring both a password (something you know) and a one-time code from a token (something you have) directly strengthens this process by implementing multi-factor authentication (MFA). This layered approach ensures that even if a password is compromised, an attacker cannot authenticate without the physical token, making the authentication component more robust. On the Cisco CyberOps Associate 200-201 exam, this concept tests your understanding of how AAA components map to security controls—a common trap is confusing authentication with authorization, which governs access rights after identity is verified. Remember, authentication answers “who you are,” while authorization answers “what you can do.” A useful memory tip: think of “AUTHentication” as proving your identity with multiple AUTHenticators, like a password plus a token.
This 200-201 practice question tests your understanding of security concepts. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company implements a policy where users must authenticate with a password and a one-time code from a token. Which AAA component is strengthened by this policy?
Authentication
Multi-factor authentication strengthens the authentication component of AAA.
Accounting
Why wrong: Accounting logs activities, not the authentication process.
Auditing
Why wrong: Auditing is not a core AAA component; it relates to review of logs.
Authorization
Why wrong: Authorization is about permissions, not the authentication method.

Correct answer & explanation
Authentication
Authentication is the AAA component that verifies the identity of a user. By requiring both a password (something you know) and a one-time code from a token (something you have), the policy implements multi-factor authentication (MFA), which directly strengthens the authentication process. This ensures that even if a password is compromised, an attacker cannot authenticate without the token.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Authentication
Why this is correct
Multi-factor authentication strengthens the authentication component of AAA.

Authorization
Why it's wrong here
Authorization is about permissions, not the authentication method.
Common exam traps
Cisco often tests the distinction between authentication and authorization, where candidates mistakenly think that adding a token strengthens authorization (access control) rather than the identity verification step.
Detailed technical explanation
Under the hood, this policy implements two-factor authentication (2FA) using a time-based one-time password (TOTP) algorithm (RFC 6238) or a hardware token generating OTPs. The AAA framework (e.g., RADIUS or TACACS+) processes the authentication request by validating both the static password (often via LDAP or Active Directory) and the dynamic token code, typically against a shared secret or seed. In real-world deployments, this mitigates credential theft attacks like phishing or password reuse, as the token code changes every 30–60 seconds.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
