VCP-VCF Administrator 2024 Question 295
Select 2You are tasked with migrating a set of virtual machines from a legacy data center to a VMware Cloud Foundation environment using VMware HCX. The legacy data center has limited bandwidth, and the migration must minimize downtime while ensuring data consistency. Which HCX migration method(s) would best meet these requirements?
- A
HCX vMotion
- B
HCX Bulk Migration
- C
HCX Cold Migration
- D
HCX Replication-Assisted vMotion (RAV)
- E
HCX OS Assisted Migration (OSAM)
Show answer and explanation
Correct answers: B, D
Explanation
In this scenario, HCX Bulk Migration and HCX Replication-Assisted vMotion (RAV) are the best options. HCX Bulk Migration uses a replication process to handle limited bandwidth and ensures minimal downtime during the switchover. HCX RAV also leverages replication but provides even lower downtime by combining it with vMotion. Other methods, such as HCX vMotion, require higher bandwidth, while HCX Cold Migration introduces significant downtime, and HCX OSAM is not applicable to pre-virtualized workloads.
- A. Incorrect.
HCX vMotion is a live migration method that minimizes downtime, but it requires high bandwidth and low latency, which is not suitable for the scenario with limited bandwidth.
- B. Correct.
HCX Bulk Migration is designed for scenarios with limited bandwidth. It uses a replication process to transfer data during off-peak hours and switches over the VMs with minimal downtime, making it a suitable option.
- C. Incorrect.
HCX Cold Migration requires the VM to be powered off for the entire duration of the migration. This would result in significant downtime, which does not meet the requirement of minimizing downtime.
- D. Correct.
HCX Replication-Assisted vMotion (RAV) combines the benefits of replication and live migration. It reduces downtime by pre-replicating the VM data and then performing a quick switchover, making it a good fit for this scenario.
- E. Incorrect.
HCX OS Assisted Migration (OSAM) is used for migrating non-vSphere workloads or physical servers to vSphere. It is not applicable in this scenario, as the workload is already virtualized.
