Which of the following statements are true about the intranet-only SC cluster network?

The intranet registration SC cluster provides only SIP registration.

The intranet SC cluster supports two distribution modes: single-active distribution and multi-active distribution.

A standalone SC should be deployed to provide registration services specifically for H.323 endpoints.

If a large number of SIP hard endpoints or soft clients are located on the intranet, you can deploy a registration SC cluster on the intranet.
