NEW QUESTION # 77
Which two statements are accurate regarding the placement of VM Clusters within an Exadata Cloud Infrastructure?

A. Multiple VM Clusters can be created within a single Exadata Cloud Infrastructure, allowing for workload isolation.
B. Each VM Cluster must be associated with its own dedicated VCN, isolating network traffic between clusters.
C. VM Clusters within the same Exadata Infrastructure can share a single VCN, simplifying network management.
D. Only one VM Cluster can exist within an Exadata Cloud Infrastructure.
E. VM Clusters can span multiple Exadata Cloud Infrastructures, providing a single, unified database environment.
