1Z0-1123-25 Question 62
Single answerYour company needs to migrate its on-premises VMware environment to Oracle Cloud VMware Solution (OCVS). You have a dedicated FastConnect link between your on-premises data center and Oracle Cloud Infrastructure (OCI). The business requires minimal downtime and wants to keep the same IP addresses for the VMs after migration to avoid reconfiguration. Which approach should you implement to meet these requirements?
- A
Use VMware HCX for live migration with an L2 stretched network between on-premises and OCVS.
- B
Export the VMs as OVAs, upload them to OCI Object Storage, then deploy them into OCVS.
- C
Shut down all on-premises VMs, perform a raw data backup using Data Transfer Appliance, and restore in OCVS.
- D
Deploy fresh VMs directly in OCVS and manually copy the data from on-premises VMs.
Show answer and explanation
Correct answer: A
Explanation
The most efficient way to achieve minimal downtime and preserve existing IP addresses when migrating workloads to Oracle Cloud VMware Solution is to use VMware HCX with vMotion and L2 stretched networking. This approach enables near-zero-downtime migrations while maintaining network configuration. For more details on HCX-based migration strategies, refer to the official Oracle Cloud VMware Solution documentation.
- A. Correct.
Correct. Using VMware HCX (Hybrid Cloud Extension) with Layer 2 (L2) stretched networking allows you to maintain the same IP addresses for your VMs while performing vMotion-based live migrations to OCVS, resulting in minimal application downtime.
- B. Incorrect.
Incorrect. Exporting and importing VMs as OVAs requires powering off the VMs, which increases downtime and disrupts business continuity. This option does not meet the requirement of minimal downtime.
- C. Incorrect.
Incorrect. Using Data Transfer Appliance is suitable for large bulk data transfers or offline migrations but involves extended downtime since VMs must be powered off and data physically shipped.
- D. Incorrect.
Incorrect. Spinning up fresh VMs in OCVS and manually copying data is time-consuming and can lead to prolonged downtime or misconfigurations. It also does not preserve existing IP addresses seamlessly.
