1Z0-1123-25 Question 77
Select 2You are planning to migrate a multi-tier application from your on-premises VMware vSphere 7.x environment to Oracle Cloud VMware Solution (OCVS). The application requires consistent IP addresses, ensures compliance with ESXi patch prerequisites, and must minimize downtime. Which two actions should you include when designing the target OCVS environment based on these migration prerequisites?
- A
Create a dedicated private subnet for the application in OCVS and configure a Layer 2 extension to preserve IP addresses during migration.
- B
Enable VMware vCenter Enhanced Linked Mode (ELM) across on-premises and OCVS environments to synchronize inventory objects in real time.
- C
Select an OCVS SDDC version that is compatible with your existing ESXi patch level, ensuring seamless vMotion and HCX operations after cutover.
- D
Use Oracle Identity Cloud Service (IDCS) exclusively for local account management to maintain granular role-based access control (RBAC).
Show answer and explanation
Correct answers: A, C
Explanation
When designing an OCVS environment for migration, you must ensure compatibility between the on-premises ESXi version and the target OCVS SDDC to avoid any operational or migration issues. Additionally, if workloads need to retain their IP addresses and minimize configuration changes, extending Layer 2 networks (for example with VMware HCX) is critical. See the Oracle Cloud VMware Solution documentation for best practices on networking setup (such as Layer 2 extension) and supported vSphere versions: https://docs.oracle.com/en/solutions/learn-oracle-cloud-vmware-solution. By following these guidelines, you can ensure a smooth migration with minimal downtime and maintenance risk.
- A. Correct.
Correct. Preserving IP addresses via a Layer 2 extension (for example, using VMware HCX Network Extension) ensures minimal application reconfiguration and reduces downtime. Creating a dedicated subnet in OCVS allows you to meet address consistency requirements and isolate traffic effectively.
- B. Incorrect.
Incorrect. Enhanced Linked Mode (ELM) can help when linking multiple vCenter Server instances, but it is not typically used to synchronize on-prem vCenter with an OCVS vCenter. In addition, OCVS operation does not rely on ELM for migration readiness. The standard approach involves HCX and sometimes Hybrid Linked Mode, not ELM.
- C. Correct.
Correct. Matching or ensuring compatibility between on-premises ESXi patch levels and the target OCVS SDDC version helps you avoid incompatibilities during live migrations (e.g., vMotion or HCX vMotion). Oracle Cloud VMware Solution supports specific versions that must align with your current vSphere environment.
- D. Incorrect.
Incorrect. While Oracle Identity Cloud Service (IDCS) can be used for authentication and SSO, it is not the exclusive means of managing permissions for OCVS. VMware� built-in vCenter roles and permissions still apply, and IDCS is not a prerequisite for preserving workloads� IP addresses or meeting ESXi compliance.
