You are building a new 12c cluster to accommodate the upcoming projects.You arecurrently working with the networkadmin team to define the requirementsneeded. Currently, thenetworkteam wouldlike to get cleared on the protocols beingused by the various network interface needed. Which three statements about Clusterware communication are correct?

A. For the private network,thenetworkadapters must use high-speed network adapters and switches that support TCP/IP. This requirement holds true inthe Microsoft Windows environment

B. For the public network, each network adapter must support TCP/IP. This requirement holds true for both Microsoft Windows and Linux/Unix environments
