1Z0-1123-25 Question 74
Select 3An organization plans to migrate 200 virtual machines from an on-premises data center to Oracle Cloud VMware Solution (OCVS). They have verified their on-premises environment meets the minimum hardware requirements and VMware versions. Which three design considerations should they adopt to ensure a successful target OCVS environment that aligns with migration prerequisites?
- A
Align on-premises vSphere version with OCVS-supported versions to ensure compatibility.
- B
Assign public subnets to your vSphere cluster management components in OCVS to enable remote console sessions over the internet.
- C
Retain valid software licensing or use bring-your-own-license (BYOL) models for VMs to remain compliant in the new environment.
- D
Implement secure connectivity between on-premises and Oracle Cloud using IPSec VPN or FastConnect for data replication and management.
- E
Extend existing on-premises VLANs into OCVS by disabling NSX-T segments for simplified networking.
Show answer and explanation
Correct answers: A, C, D
Explanation
When designing the target OCVS environment for migration, key considerations include version compatibility with vSphere, abiding by software licensing requirements, and establishing secure connectivity (IPSec VPN or FastConnect) between on-premises and the cloud. Refer to Oracle's documentation on OCVS design best practices, which highlights the importance of private subnets for management traffic and underscores NSX-T's integral role in the OCVS networking stack.
- A. Correct.
Correct. Ensuring that the on-premises vSphere version matches what Oracle Cloud VMware Solution supports is critical. Running an unsupported version prevents the use of certain features, can break compatibility with OCVS, and is against best practice guidelines.
- B. Incorrect.
Incorrect. Management components (e.g., vCenter, NSX Manager) in OCVS typically reside in private subnets to reduce exposure to the internet. Remote console access usually happens through a VPN or bastion access. Placing them on public subnets is not a recommended design.
- C. Correct.
Correct. BYOL or ensuring existing licenses are valid is a core prerequisite. Many software vendors require proper licensing in the cloud, and failing to verify license portability introduces compliance risks.
- D. Correct.
Correct. IPSec VPN or FastConnect are standard methods to securely connect on-premises networks with OCVS. They provide reliable, low-latency, and encrypted connections for migration, replication, and administrative traffic.
- E. Incorrect.
Incorrect. You cannot simply disable NSX-T segments in OCVS to extend your on-premises VLANs into the cloud. NSX-T underpins the software-defined networking in OCVS, and extending VLANs directly is neither supported nor advisable from a design perspective.
