Which of the following types of physical security features a passcode generated from an algorithm?

The correct answer is D. RSA Token. An RSA Token (such as RSA SecurID) is a hardware or software security token that generates a time-based one-time password (TOTP) using a cryptographic algorithm, typically synchronized with a server. The code changes at set intervals (e.g., every 60 seconds) and is valid only…

Explanation

An RSA Token (such as RSA SecurID) is a hardware or software security token that generates a time-based one-time password (TOTP) using a cryptographic algorithm, typically synchronized with a server. The code changes at set intervals (e.g., every 60 seconds) and is valid only once. A Key Fob (A) can sometimes generate codes but is a broader, less specific term often associated with proximity access rather than algorithmic passcode generation. An RFID Badge (B) transmits a stored identifier via radio frequency and does not generate algorithmic codes. Biometrics (C) uses physical characteristics like fingerprints, not generated passcodes.
