1Z0-1123-25 Question 75
Select 2Your organization is planning to migrate an on-premises VMware environment running a supported vSphere version (e.g., vSphere 7.0) to Oracle Cloud VMware Solution (OCVS). Management wants minimal downtime and seamless workload transfer. As part of designing the target OCVS environment based on migration pre-requisites, which two actions must be included to ensure a successful migration?
- A
Ensure the on-premises vSphere version is supported by OCVS and validate network connectivity for VMware HCX.
- B
Disable VLAN trunking on the OCVS environment to minimize overhead and simplify port-group assignments.
- C
Rely solely on on-premises storage for all workload data and keep the vSAN service disabled in OCVS.
- D
Plan adequate CPU, memory, and storage capacity in OCVS to match or exceed on-premises resource usage.
Show answer and explanation
Correct answers: A, D
Explanation
Before migrating to Oracle Cloud VMware Solution, it is essential to confirm that your on-premises environment is on a supported vSphere version and that you have enabled the correct networking (e.g., VLAN trunking and HCX readiness). Additionally, proper resource sizing (CPU, memory, and storage) in the OCVS environment must meet or exceed on-premises usage to avoid performance bottlenecks. Refer to the official Oracle Cloud VMware Solution documentation for details on supported versions, networking design, and capacity planning best practices.
- A. Correct.
Ensuring a supported vSphere version and proper network connectivity for VMware HCX is crucial. OCVS relies on a compatible VMware stack and HCX for smooth live migrations and minimal downtime. Without HCX, certain migrations would require more manual steps or downtime.
- B. Incorrect.
Disabling VLAN trunking on the OCVS environment is not a best practice. You need VLAN trunking or virtual networking constructs for extending on-premises networks, especially for live migration scenarios that rely on layer 2 network extension.
- C. Incorrect.
Relying exclusively on on-premises storage defeats the purpose of deploying OCVS, which includes vSAN for local storage. Maintaining vSAN in OCVS is a fundamental part of the VMware infrastructure in the cloud. Simply disabling it can lead to unsupported configurations and hinder performance.
- D. Correct.
Planning adequate CPU, memory, and storage capacity in OCVS to match or exceed on-premises usage is essential. Migrated workloads require enough resources in the cloud environment to accommodate normal and peak load operations without performance degradation.
