Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Compartment boundaries
Why it's wrong here
Compartments are logical IAM organization tools, not physical or virtualization boundaries on Exadata hardware.
- ✓
Exadata VM Clusters
Why this is correct
Exadata VM clusters allow you to partition a single Exadata infrastructure rack into multiple isolated virtual machine environments.
- ✗
Oracle Multitenant container databases with PDB isolation
Why it's wrong here
PDBs isolate schemas within a single database instance, but do not provide separate VM cluster OS boundaries.
- ✗
Dynamic Routing Gateways (DRG)
Why it's wrong here
DRGs handle routing between VCNs and on-premises networks, not hypervisor clustering.
