1Z0-1123-25 Question 65
Select 2A large financial services company needs to migrate a mission-critical VMware environment from their on-premises data center to Oracle Cloud VMware Solution (OCVS). They require minimal downtime for applications handling real-time transactions. Which two design decisions should be implemented to achieve a seamless migration with limited disruption? (Choose two)
- A
Use HCX Bulk Migration over the Internet to transfer VMs in batches
- B
Rely only on an IPsec VPN tunnel for live vMotion traffic between on-premises and OCVS
- C
Implement HCX Enterprise with WAN optimization to support vMotion-based migrations
- D
Leverage Oracle Cloud Infrastructure FastConnect to establish a dedicated, low-latency network
Show answer and explanation
Correct answers: C, D
Explanation
In most production environments, minimizing downtime for critical applications requires robust connectivity and efficient migration tools. HCX Enterprise enables live workload migrations (vMotion) with WAN optimization, while Oracle FastConnect provides the dedicated bandwidth and low latency needed to avoid migration failures or bottlenecks. These solutions align with Oracle Cloud best practices for seamlessly migrating VMware workloads to OCVS. Refer to Oracle� �Deploying Oracle Cloud VMware Solution� documentation for specific implementation guidelines.
- A. Incorrect.
Option A: Use HCX Bulk Migration over the Internet to transfer VMs in batches. (Incorrect) HCX Bulk Migration is useful for scheduling large-scale migrations, but it usually requires a brief downtime window during the final cutover. Also, using only the public Internet for critical, latency-sensitive traffic can introduce unpredictable performance and does not ensure minimal downtime if the network becomes a bottleneck.
- B. Incorrect.
Option B: Rely only on an IPsec VPN tunnel for live vMotion traffic between on-premises and OCVS. (Incorrect) While an IPsec VPN tunnel can provide a secure connection, it often does not guarantee the low-latency, high-bandwidth conditions needed for reliable live vMotion of mission-critical workloads. This can lead to migration failures or significantly increased cutover times.
- C. Correct.
Option C: Implement HCX Enterprise with WAN optimization to support vMotion-based migrations. (Correct) HCX Enterprise supports live vMotion capabilities and includes WAN optimization features to reduce bandwidth requirements and latency. This approach helps keep applications running with minimal downtime by allowing active workloads to be transferred with minimal disruption.
- D. Correct.
Option D: Leverage Oracle Cloud Infrastructure FastConnect to establish a dedicated, low-latency network. (Correct) FastConnect provides a dedicated, private connection between on-premises and OCI. For large-scale, mission-critical VMware workloads, FastConnect is recommended for high performance, reduced latency, and more predictable network throughput during live migrations.
