What is the process of validating a user to provide access?

• A. Authentication
• B. Authorization
• C. Attenuation
• D. Backup

Answer: (A)

Authentication is the process of validating a user’s claimed identity before granting access. It answers “Are you who you say you are?” by using credentials or proofs such as a username and password, a fingerprint or facial scan, a hardware token, or a one-time code. Once authentication succeeds, the system recognizes who you are and can apply appropriate permissions (authorization) to determine what you’re allowed to do. The other options don’t fit because attenuation relates to signal loss in networks, and backup is about making copies of data for protection, not verifying identity for access.
