1Z0-997-25 Question 120
Select 2Your organization is planning a hybrid cloud architecture that extends its on-premises VMware environment into Oracle Cloud VMware Solution (OCVS) on Oracle Cloud Infrastructure (OCI). You must ensure secure, low-latency connectivity for critical workloads and minimal downtime during workload migrations. You also want to maintain unified administration for your VMware resources. Which two actions should you take to meet these requirements?
- A
A. Establish secure connectivity by using an IPSec VPN or OCI FastConnect link to connect your on-premises data center to the Oracle Cloud VMware environment.
- B
B. Migrate workloads using Oracle Data Guard integration for VMware Virtual Machines to achieve near-zero downtime.
- C
C. Deploy a single vCenter instance that simultaneously manages both your on-premises ESXi hosts and OCVS ESXi hosts within OCI.
- D
D. Enable VMware HCX to facilitate migration of on-premises Virtual Machines to OCVS with minimal downtime and consistent network configurations.
Show answer and explanation
Correct answers: A, D
Explanation
When designing a hybrid cloud with Oracle Cloud VMware Solution, you must establish secure network connectivity (e.g., IPSec VPN or OCI FastConnect) and leverage modern VMware tools such as HCX for workload migrations. HCX enables minimal downtime migrations and preserves network settings, making it ideal for mission-critical environments. Oracle Data Guard replication specifically handles Oracle databases and is not suitable for migrating entire VMware deployments. Meanwhile, the OCVS vCenter remains separate from your on-premises vCenter, but features like Hybrid Linked Mode can provide limited unified visibility without merging the two vCenters into one.
- A. Correct.
A. Correct. IPSec VPN or OCI FastConnect is used to secure and optimize connectivity between on-premises and OCVS. FastConnect offers dedicated bandwidth and improved latency, suitable for mission-critical VMware workloads. IPSec VPN is a cost-effective and secure alternative for smaller or less latency-sensitive environments.
- B. Incorrect.
B. Incorrect. Oracle Data Guard is a replication solution for Oracle Databases, not for generic VMware Virtual Machines. While Data Guard can protect Oracle Database workloads within VMs, it does not provide near-zero downtime migration for VMware Virtual Machines themselves.
- C. Incorrect.
C. Incorrect. OCVS manages ESXi hosts using a separate vCenter instance provisioned in OCI. You cannot combine your on-premises ESXi hosts and OCVS ESXi hosts under a single vCenter instance directly. You can, however, use Hybrid Linked Mode for limited cross-environment management, but they remain distinct vCenter deployments.
- D. Correct.
D. Correct. VMware HCX can migrate on-premises Virtual Machines to OCVS with minimal downtime. It also preserves VM networking configurations, aiding in seamless migrations and consistent operations as part of a hybrid cloud strategy.
