1Z0-997-26 Workload Migration Practice Question
You are migrating a tiered enterprise application suite to OCI. Certain legacy components require specific static MAC addresses and direct layer 2 broadcast communication, which standard OCI virtual cloud networks (VCNs) do not support by default. Which THREE OCI architectural approaches or features can you utilize to solve this requirement? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy Oracle Cloud VMware Solution (OCVS), which provides a fully dedicated VMware SDDC environment supporting standard VLANs and layer 2 guest networking.
Standard VCN virtual network interfaces (VNICs) have dynamic MAC addresses and do not support layer 2 broadcasts. To support L2 networking or custom MAC requirements, architects can utilize Oracle Cloud VMware Solution (OCVS), Bare Metal instances with SR-IOV, or OCI Flexible Virtual NIC options with spoof checking disabled.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy Oracle Cloud VMware Solution (OCVS), which provides a fully dedicated VMware SDDC environment supporting standard VLANs and layer 2 guest networking.
Why this is correct
OCVS supports VMware NSX and standard VLANs, preserving layer 2 networking requirements.
- ✓
Use OCI Bare Metal compute instances that support SR-IOV (Single Root I/O Virtualization) for direct hardware network access and custom MAC configurations.
Why this is correct
Bare metal instances with SR-IOV allow direct access to physical network adapters and custom configurations.
- ✗
Enable OCI Load Balancer TCP termination without backend health checks.
Why it's wrong here
Load balancing operates at L4/L7 and does not provide layer 2 bridging or custom MAC support.
- ✓
Configure OCI VCN VNICs with customized MAC addresses where supported or utilize secondary private IPs with IP aliasing.
Why this is correct
OCI VNICs allow specifying custom MAC addresses upon creation for certain bare metal and advanced shape configurations.
- ✗
Rely on standard OCI Internet Gateways to bridge layer 2 broadcast domains across the public internet.
Why it's wrong here
Internet Gateways route L3 IP packets; they do not bridge layer 2 broadcast domains.

| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
