1Z0-1123-25 Question 76
Select 2Your company is migrating an on-premises VMware vSphere 7 environment to Oracle Cloud VMware Solution (OCVS). As part of the design phase, you need to ensure the target OCVS environment meets the migration prerequisites. Which two considerations are crucial to confirm before creating your OCVS SDDC to guarantee a successful migration?
- A
Ensure that each ESXi host in OCVS has at least as many vCPUs as on-premises to maintain performance consistency.
- B
Enable hybrid linked mode before deploying the OCVS SDDC so it automatically synchronizes on-premises user roles.
- C
Validate that the on-premises VMware vSphere version is supported by OCVS for replication and vMotion compatibility.
- D
Create and attach an OCI Block Volume group to the OCVS SDDC cluster to handle data replication across regions by default.
- E
Confirm that your existing VCN subnets are sized to accommodate the ESXi hosts, vCenter, and NSX traffic in the OCVS environment.
Show answer and explanation
Correct answers: A, C
Explanation
When designing the target OCVS environment, it is critical to confirm that the VMware version running on-premises is supported by OCVS to avoid compatibility issues during vMotion or replication. In addition, verify that each ESXi host in the cloud will have sufficient CPU resources to match or exceed on-premises performance. These steps ensure there are no major performance regressions or incompatibility problems. For guidance, refer to the official Oracle Cloud VMware Solution documentation, which outlines supported VMware software versions and recommended host shapes: https://docs.oracle.com/en/solutions/vmware-solution-overview
- A. Correct.
Correct. Matching or exceeding on-premises vCPUs in the OCVS environment ensures workloads perform as expected. OCVS hosts come in defined shapes, so verifying compute parity upfront is crucial for a successful migration.
- B. Incorrect.
Incorrect. While hybrid linked mode can link on-premises vCenter with cloud vCenter, it is generally configured after the OCVS SDDC is up and running, not before deployment. Enabling it prematurely is not a migration prerequisite.
- C. Correct.
Correct. OCVS supports specific VMware versions, and ensuring vSphere 7 compatibility with OCVS is mandatory for seamless migrations, including vMotion and replication.
- D. Incorrect.
Incorrect. Attaching an OCI Block Volume group for data replication across regions by default is not a standard approach in OCVS. Typically, additional replication or DR solutions (like VMware Site Recovery Manager) are used if multi-region replication is required.
- E. Incorrect.
Incorrect. While sizing subnets is important, it must account for IP address requirements for ESXi hosts, vCenter, and NSX components. However, this alone is not considered a top prerequisite over verifying vCPU capacity and VMware version compatibility. Subnet sizing is part of network planning rather than a specific migration prerequisite.
