1Z0-1123-25 Question 66
Select 2Your organization is migrating virtual machines from an on-premises VMware environment to Oracle Cloud VMware Solution (OCVS). You must maintain the same IP addresses for these VMs after the migration to minimize downtime and application reconfiguration. Which TWO steps are required to achieve this using VMware HCX?
- A
A. Set up an HCX Network Extension (L2 extension) from on premises to OCVS.
- B
B. Reassign VM IP addresses to the new subnet in OCVS before the migration.
- C
C. Establish secure connectivity (via IPSec VPN or FastConnect) between on premises and OCVS.
- D
D. Modify the OCVS vCenter to create a NAT rule for each VM.
Show answer and explanation
Correct answers: A, C
Explanation
To retain the same IP addresses after migrating VMs to Oracle Cloud VMware Solution (OCVS), you must leverage VMware HCX network extension (L2 extension) and ensure secure connectivity between on-premises and OCI. HCX Network Extension preserves IP addresses by stretching the on-prem subnet into the OCVS SDDC, and either IPSec VPN or FastConnect establishes a secure communication channel for data transfer. Refer to the Oracle Cloud VMware Solution documentation for guidance on configuring HCX and networks for seamless hybrid deployments.
- A. Correct.
A. Correct. An HCX Network Extension (also known as L2 extension) allows VMs to retain their original IP addresses while migrating between on-prem and the OCVS environment, helping avoid DNS or routing changes.
- B. Incorrect.
B. Incorrect. Reassigning IP addresses to use a new subnet in OCVS would not preserve the existing addresses. This option conflicts with the requirement to keep the original IP addresses.
- C. Correct.
C. Correct. You must have secure and reliable network connectivity (IPSec VPN or Oracle FastConnect) between on premises and OCVS for HCX to perform live migrations. Without this connection, HCX cannot transfer VM data or extend networks.
- D. Incorrect.
D. Incorrect. NAT rules are not required for preserving on-prem IP addresses. NAT translates IP addresses rather than extending the same subnet end to end.
