220-1102 Question #663: Real Exam Question with Answer & Explanation

Question

A user authenticates to Windows with a complex password. The user frequently makes errors when entering the password and gets locked out. Which of the following can ensure security while reducing user error? (Choose two.)

Options

• ASingle sign-on
• BPersonal identification number
• CFingerprint
• DFacial recognition
• EHardware token
• FMultifactor authentication

Explanation

To improve security and reduce user errors with complex passwords, biometric authentication methods offer convenient and secure alternatives.

Common mistakes.

• A. Single sign-on simplifies access to multiple applications but still relies on an initial authentication method, which could still be a complex password.
• B. A Personal Identification Number (PIN) is a shorter password and can reduce typing errors but offers less security than a complex password and is not a biometric method.
• E. A hardware token typically generates a one-time password or provides a cryptographic key, which still often requires user interaction or is used in conjunction with a password for multi-factor authentication.
• F. While enhancing security, multi-factor authentication (MFA) typically adds another factor in addition to the password, which doesn't directly reduce the error rate of typing the initial complex password.
