MFA requires two or more different types of authentication factors from the following categories:
Something you know (e.g., password, PIN)
Something you have (e.g., smart card, security token)
Something you are (e.g., fingerprint, retina scan)
Using a smart card (something you have) and a password (something you know) fulfills the requirement of MFA by combining two different types of factors.
Multifactor authentication can be performed using a multifactor authenticator or by a combination of authenticators that provide different factors. The three authentication factors are something you know, something you have, and something you are
This question is related to something you have and something you know! TestOut thinks it's PIN and password which I disagree on because PIN and password are both something you know! D is the one.
The example of MFA (Multi-Factor Authentication) is A. Fingerprint scan and retina scan.
MFA is a security mechanism that requires the user to provide two or more authentication factors to verify their identity. These factors are typically categorized into three types:
Something the user knows, such as a password or PIN.
Something the user has, such as a smart card or token.
Something the user is, such as a fingerprint, retina scan, or other biometric data.
In this example, the user is required to provide two different biometric factors, a fingerprint scan and a retina scan, to verify their identity. This provides a high level of security since it is difficult for an attacker to fake both biometric factors.
Your answer and example are not right. Please understand MFA before leaving comments.
CompTIA CertMaster Learn for A+ 220-1102, the definition of MFA is as follows:
Authentication scheme that requires the user to present at least two different factors as credentials; for example, something you know, something you have, something you are, something you do, and SOMEWHERE you are. Specifying two factors is known as 2FA.
Also, there are 5 categories. Researching is important in IT. This will continue throughout your career, especially if you plan to pursue a career in penetration testing.
Because password and pin are both something you know . For MFA you need 2 different authentications. D is the correct answer
