The correct answer is C. The IOPS on the SAN backing the on-premises cluster. As more VMs are migrated simultaneously, the underlying SAN must handle increasing read operations. If the SAN’s IOPS capacity becomes saturated, throughput drops significantly, causing the migration rate to fall from 250Mbps to 25Mbps. This makes storage IOPS the most likely…
Question
A systems engineer is migrating a batch of 25 VMs from an on-premises compute cluster to a public cloud using the public cloud’s migration agent. The migration job shows data copies at a rate of 250Mbps. After five servers migrated, the remaining data copied at a rate of 25Mbps. Which of the following is the most likely cause of the issue?
Options
- AThe local VM host hardware utilization
- BThe ISP throttling rate
- CThe IOPS on the SAN backing the on-premises cluster
- DThe compute utilization of the VMs being migrated

Explanation
As more VMs are migrated simultaneously, the underlying SAN must handle increasing read operations. If the SAN’s IOPS capacity becomes saturated, throughput drops significantly, causing the migration rate to fall from 250Mbps to 25Mbps. This makes storage IOPS the most likely bottleneck.
