1Z0-1123-25 Question 63
Single answerYour company needs to migrate a critical production workload from its on-premises VMware environment to Oracle Cloud VMware Solution (OCVS). The workload consists of multiple large virtual machines (VMs) running business-critical applications that must remain online as long as possible. You want to minimize downtime and ensure the shortest cutover window. Which approach should you use to achieve a near-seamless migration with minimal service disruption?
- A
Use VMware HCX to replicate the VMs in the background and perform a planned cutover during a maintenance window.
- B
Use Oracle Database Migration to copy disk images directly from on-premises to OCVS.
- C
Power off on-premises VMs and manually copy VMDK files to Object Storage, then import them into OCVS.
- D
Deploy Oracle Container Engine for Kubernetes (OKE) to containerize the VMs before moving them to OCVS.
Show answer and explanation
Correct answer: A
Explanation
VMware HCX is the recommended solution for migrating VMware-based workloads to Oracle Cloud VMware Solution with minimal downtime. By replicating VMs in the background and performing a final synchronization and cutover, HCX drastically reduces outage windows. Oracle's documentation and best practices emphasize HCX as the primary tool for efficient, low-disruption migrations to OCVS.
- A. Correct.
Correct. HCX is designed for live migrations and replication from on-premises VMware environments to OCVS. It replicates VMs in the background, allowing a scheduled cutover with minimal downtime.
- B. Incorrect.
Incorrect. Oracle Database Migration is specifically intended for database transfers, not the migration of entire VMware workloads with multiple VMs.
- C. Incorrect.
Incorrect. Manually copying VMDK files requires extended downtime and involves a more error-prone, labor-intensive process that does not minimize disruption for critical workloads.
- D. Incorrect.
Incorrect. Converting VMs to containers in OKE does not apply to standard VMware migrations. It would also require significant re-architecting of the applications, which is not ideal when minimal downtime is required.
