What are the two AAA methods for user authentication when configuring the IKEv2 profile? (Choose two.)

user is not a valid keyword in the IKEv2 profile authentication command syntax and is not a recognized AAA authentication method in Cisco IOS.

EAP is used in IKEv2 profiles to delegate user authentication to an AAA server, supporting methods such as EAP-MSCHAPv2 for username and password verification, making it a primary AAA user authentication method in IKEv2 profile configuration.

rsa-sig uses RSA digital signatures for certificate-based peer or device authentication and is not classified as an AAA user authentication method in the IKEv2 profile context.

cert is not a standard keyword in Cisco IOS IKEv2 profile authentication configuration - certificate-based authentication is specified using rsa-sig or ecdsa-sig, not cert.

Pre-share configures a pre-shared key as the authentication credential within the IKEv2 profile, and it is recognized as a valid AAA authentication method in the authentication command syntax of an IKEv2 profile.
