- A
AWS Shield
Why wrong: AWS Shield is a DDoS protection service. It protects applications from distributed denial of service attacks and has no role in multi-factor authentication for console access.
- B
Multi-Factor Authentication (MFA)
MFA requires users to provide a second authentication factor — a time-based one-time password (TOTP) from an authenticator app — in addition to their password. This significantly reduces the risk of compromised credentials.
- C
AWS WAF
Why wrong: AWS WAF is a web application firewall that protects web applications from common exploits. It operates at the HTTP layer and does not control AWS console authentication.
- D
Amazon Cognito
Why wrong: Amazon Cognito manages user authentication for customer-facing applications. IAM console MFA is a separate feature built into IAM itself, not managed through Cognito.
Quick Answer
The answer is Multi-Factor Authentication (MFA). This is the correct security control because it enforces the principle of verifying identity using two independent factors: something the user knows, like a password, and something the user has, such as a one-time code generated by an authenticator app. By requiring both a password and that temporary code, MFA directly satisfies the company’s need for layered verification before granting console access, dramatically reducing the risk of unauthorized entry even if a password is stolen. On the AWS Certified Cloud Practitioner CLF-C02 exam, this concept tests your understanding of the shared responsibility model and basic IAM security features; a common trap is confusing MFA with a simple password policy or a security group rule. Remember that MFA always combines two different categories—knowledge and possession—so a useful memory tip is “know + have = MFA,” where the authenticator app provides the “have” factor.
CLF-C02 Security and Compliance Practice Question
This CLF-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.
A company wants all IAM users to verify their identity with both a password and a one-time code from an authenticator app before accessing the AWS Management Console. Which security control should the company enable?

Correct answer & explanation
Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is the correct security control because it requires users to present two independent factors: something they know (password) and something they have (a one-time code from an authenticator app). This satisfies the company's requirement for both a password and a one-time code before accessing the AWS Management Console, significantly reducing the risk of unauthorized access even if a password is compromised.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS WAF or Amazon Cognito with IAM MFA, but the question specifically asks for the security control that enforces both a password and a one-time code for IAM users, which is exclusively Multi-Factor Authentication (MFA) within IAM.
Detailed technical explanation
How to think about this question
Under the hood, AWS IAM MFA leverages Time-based One-Time Password (TOTP) as defined in RFC 6238, where the authenticator app generates a 6-digit code that changes every 30 seconds. When an IAM user signs in, AWS validates the password against the stored hash and then verifies the TOTP code against the shared secret key provisioned during MFA device setup. In a real-world scenario, if a user's password is leaked via phishing, MFA prevents the attacker from accessing the console because they lack the physical authenticator device.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- 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.
