Cisco Finesse primary and secondary servers accept both self-signed certificates and certificate authority certificates when HTTPS protocol is used to access the administration console or agent desktop in Cisco Finesse. A self-signed certificate is a certificate that is generated by the server itself and is not verified by a trusted third-party. A certificate authority certificate is a certificate that is issued by a trusted third-party vendor and is used to establish a secure connection between the server and the client. Cisco Finesse supports both types of certificates for HTTPS connections, but recommends using certificate authority certificates for better security and compatibility. Domain validation certificates, digital certificates, and root certificates are not valid options for this question. A domain validation certificate is a type of certificate authority certificate that only verifies the ownership of the domain name, but not the identity of the organization. A digital certificate is a general term that refers to any certificate that uses public key cryptography to authenticate the identity of the sender and the integrity of the data. A root certificate is a certificate that is used to validate other certificates in a chain of trust, but it is not directly used for HTTPS connections. References: Cisco Finesse Administration Guide, Release 12.6 (2) - Getting Started [Cisco Finesse] - Cisco1, Solved: Finesse Certificate Issue - Cisco Community2, Cisco Finesse Administration Guide Release 11.6(1)3, Cisco Finesse Administration Guide, Release 12.0 (1)4, Cisco Finesse Administration Guide, Release 12.6 (1)5
