Which two statements distinguish authentication from accounting? (Choose two.)

User activity audits are a core function of accounting, which logs what resources were accessed and when, not authentication.

Authentication is the process that verifies a user's identity by challenging them for credentials, such as a username and password, and then granting or denying access based on the verification.

The primary purpose of authentication is to validate who a user or device claims to be, establishing their identity before granting network access.

Recording the duration of a user's connection is an accounting function, as accounting tracks resource consumption and session details.

Providing supporting information for billing users is a function of accounting, which monitors and records resource usage for financial or administrative purposes.
