1Z0-997-25 Question 125
Select 2Your company runs critical workloads on an on-premises VMware environment and wants to migrate them to Oracle Cloud VMware Solution (OCVS) while maintaining a consistent security posture and minimizing downtime. You are designing a hybrid cloud architecture to ensure seamless connectivity and workload portability between on-premises and OCVS. Which two approaches should you include in your design?
- A
Use Oracle Cloud Infrastructure FastConnect or IPSec VPN to establish secure, reliable connectivity between the on-premises data center and OCVS
- B
Implement VMware HCX to extend Layer 2 networks and perform live migrations of virtual machines to OCVS
- C
Assign ephemeral public IP addresses directly to each migrated VM to bypass on-premises VLAN constraints
- D
Rely on manual VM export and import methods to replicate on-premises VMs into OCVS
Show answer and explanation
Correct answers: A, B
Explanation
When designing a hybrid cloud architecture with Oracle Cloud VMware Solution, secure connectivity and minimal downtime are paramount. FastConnect or IPSec VPN ensures reliable and secure network connectivity between on-premises environments and OCVS. VMware HCX offers seamless, often near-zero-downtime migrations and network extension to maintain existing IP addressing, reducing complexity. Detailed guidance and best practices can be found in the Oracle Cloud VMware Solution documentation (https://docs.oracle.com/en-us/iaas/Content/VMware/Concepts/ocvsoverview.htm).
- A. Correct.
Correct � Leveraging FastConnect or IPSec VPN is a recommended best practice for establishing secure hybrid connectivity. FastConnect provides dedicated, high-bandwidth connectivity, while IPSec VPN offers an encrypted tunnel over public internet. Both ensure reliable performance and security between on-premises networks and OCVS.
- B. Correct.
Correct � VMware HCX is designed to facilitate live or staged migration of workloads from on-premises VMware environments to OCVS. It provides Layer 2 extension and migration tools that help maintain the same IP addresses for VMs, minimizing downtime and ensuring network consistency.
- C. Incorrect.
Incorrect � Assigning ephemeral public IPs to each migrated VM is not a best practice for creating a hybrid cloud architecture with consistent on-premises and cloud networking. This approach could compromise security and lead to disjointed network configurations.
- D. Incorrect.
Incorrect � Manually exporting and importing VMs is time-consuming, can lead to extended downtime, and lacks the automation required for large-scale or frequent migrations. This method does not effectively support a well-architected minimal-downtime strategy.
