Configuring key/value pairs on a RADIUS server is associated with deploying which of the following?

WPA2-Enterprise relies on the 802.1X authentication framework, which uses a RADIUS server as the AAA (Authentication, Authorization, and Accounting) backend. RADIUS communicates using attribute-value pairs - also called key/value pairs - to convey authentication data such as usernames, passwords, VLAN assignments, and session policies between the wireless access point and the authentication server. Configuring these pairs on the RADIUS server is a standard and required step in deploying WPA2-Enterprise.

DNS secondary zones are configured on DNS servers to provide zone redundancy and have no relationship to RADIUS servers or key/value pair configuration.

Digital certificates are issued and managed by a Certificate Authority within a PKI infrastructure, not configured through RADIUS attribute-value pairs.

Intrusion detection systems are configured to analyze network traffic and event signatures for threats and are not deployed or configured via RADIUS.
