1Z0-902 Exam Question 1

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 cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.

D.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.
