1Z0-997-25 Question 121
Select 2Your financial services company hosts a critical on-premises VMware vSphere environment and plans to extend capacity into Oracle Cloud Infrastructure (OCI) using Oracle Cloud VMware Solution. The goal is seamless workload mobility with minimal downtime and secure network connectivity. Which two design considerations are crucial for achieving these requirements?
- A
Use VMware HCX for Layer 2 extension and migration of on-premises virtual machines to OCI, preserving the same IP addressing scheme across both environments.
- B
Rely on a site-to-site IPSec VPN over the public Internet as your primary production connectivity to save on bandwidth costs.
- C
Leverage Oracle Cloud FastConnect or an IPSec VPN with sufficient bandwidth to minimize latency for real-time replication and workload migration.
- D
Manage cross-environment vMotion directly by merging on-premises and OCI vCenter Servers into a single instance without VMware HCX.
Show answer and explanation
Correct answers: A, C
Explanation
When designing a hybrid solution with Oracle Cloud VMware Solution, it is vital to use VMware HCX for workload mobility and consistent L2 networking, as well as to establish robust connectivity over FastConnect or an efficiently provisioned IPSec VPN to handle production traffic. Reliance on public Internet routes for critical workloads can lead to performance and reliability issues. For more details, see the official Oracle Cloud VMware Solution documentation: https://docs.oracle.com/en-us/iaas/Content/VMware/Concepts/oci_vmware.htm.
- A. Correct.
Correct. VMware HCX supports seamless migrations and Layer 2 network extension, allowing on-premises virtual machines to keep their IP addresses when moving to or from the Oracle Cloud VMware environment.
- B. Incorrect.
Incorrect. Although an IPSec VPN can be used if FastConnect is not available, relying solely on the public Internet for production workloads typically introduces unpredictable latency and bandwidth constraints, which can disrupt critical applications.
- C. Correct.
Correct. FastConnect or an appropriately configured IPSec VPN provides dedicated, lower-latency connectivity essential for real-time replication and stable migration between your on-premises data center and OCI.
- D. Incorrect.
Incorrect. You cannot simply merge vCenter Servers across on-premises and OCI environments for cross-environment vMotion. Hybrid Linked Mode is possible, but VMware HCX is the recommended approach to support seamless migrations and workload mobility.
