Show Suggested Answer

Suggested Answer: A, B, D

For a non-virtual deployment of Oracle Exadata with a single cluster:

Single Client Access Name (SCAN) Listeners: By default, three SCAN listeners are configured on the RDMA over Converged Ethernet (RoCE) network. This setup allows for load balancing and high availability of incoming client connections across the cluster nodes.

Oracle Cluster Registry (OCR) Multiplexing: The OCR is typically stored in multiple locations within the disk groups to enhance reliability and fault tolerance. On Exadata, the OCR is multiplexed across the DATA and RECO disk groups for enhanced resilience.

ora.diskmon Resource: This is an essential component of Oracle Clusterware, responsible for monitoring and managing disk-related cluster resources. It is always enabled and kept online by Oracle Clusterware on Exadata systems.
