Which two items are components of a PKI? (Choose two.)

A Public Key Infrastructure (PKI) relies on a Certificate Authority (CA) to issue and manage digital certificates, which bind public keys to entities. The CA is a trusted third party that verifies the identity of certificate requesters. Certificate Revocation Lists (CRLs) are also essential components of a PKI. CRLs are lists of certificates that have been revoked before their expiration date, ensuring that compromised or invalid certificates are no longer trusted. Preshared keys and clear-text passwords are used for authentication but are not components of a PKI itself; PKI uses certificates for authentication. An RSA token is a type of hardware token often used for multi-factor authentication, but it's not a core component of the PKI framework.
