How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

A. With Secure Fabric isolation, each Database VM Guest uses a dedicated network partition and VLAN ID for client networking between application servers. This improves security by preventing man in the middle attacks.

B. With Secure Fabric isolation, each Storage Server runs multiple KVM guests each dedicated to a Database VM cluster using a dedicated network partition and VLAN ID. This provides security and isolation between multiple tenants or VM clusters.

C. With Secure Fabric isolation, each Database VM Cluster uses a dedicated network partition and VLAN ID for Data Guard networking between the primary and disaster recovery Exadata racks. This improves security by isolating data guard traffic onto an encrypted network between data centers.

D. With Secure Fabric isolation, each Database VM cluster uses a dedicated network partition and VLAN ID for cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.

Which statement is true about the Persistent Memory Commit Accelerator?

A. Persistent Memory Commit Accelerator contains logging information from all tiers of the software stack for rapid triage and diagnostics.

B. Persistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.

C. Persistent Memory Commit Accelerator copies redo log data from disk for faster redo apply on Data Guard Standby Databases.

D. Persistent Memory Commit Accelerator helps to further reduce redo log write latency by using Persistent Memory and Remote Direct Memory Access (RDMA).

E. Persistent Memory Commit Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash.
