Multiple Choice

PEAP is a popular extended EAP protocol.

Explanation:
PEAP is a widely deployed EAP method for wireless networks. It protects credentials by creating a TLS tunnel before the inner authentication, so the user’s username/password (or other inner methods) are transmitted securely over the network. This combination makes PEAP highly practical for enterprise environments, as it works with existing PKI infrastructure (server certificates) and central RADIUS-based authentication, enabling secure access without requiring client certificates on every device. Its broad compatibility and balance of security and ease of deployment explain why it’s considered a popular extended EAP protocol. The other options contradict its established, widespread use.
