Explanation
A: Oracle Clusterware Daemon (CRSD) CRS daemon (Oracle Cluster Ready Services Daemon) internode connection. The port number is assigned automatically during installation. You cannot view or modify it afterward. This port is used exclusively with the cluster interconnect. D: To set up an Oracle 11g R2 RAC installation using Oracle Grid Naming Services (GNS) the following requirements need to be met: * At least two interfaces configured on each node, one for the private IP address and one for the public IP address. * A Domain Naming Server (DNS) running in the network for the address resolution of the GNS virtual IP address and hostname. * The DNS entry to configure the GNS sub-domain delegation * A DHCP server running on the same public network as your Oracle RAC cluster. Within the subdomain, the GNS uses multicast Domain Name Service (mDNS) (not B), included with Oracle Clusterware (not E), to enable the cluster to map host names and IP addresses dynamically as nodes are added and removed from the cluster, without requiring additional host configuration in the DNS.
