Which two are examples of server role?

According to the Avaya Workforce Engagement Support Installation Guide, server roles are components that provide specific functions and services for Avaya Workforce Engagement Support. Some examples of server roles are Recorder Integration Service and Avaya Contact Recorder. Recorder Integration Service is a server role that enables the recorder to communicate with the switch and receive call signaling and metadata. Avaya Contact Recorder is a server role that provides the recording, search, playback, and storage of voice interactions. The other options, such as Enterprise Manager and Framework Integration Service, are not server roles, but applications that run on servers. References: Avaya Workforce Engagement Support Installation Guide, page 18.
