Question

Storage vMotion can now use one of the two technologies to copy data from source to destination. What are they?

A) Network File Copy (NFC).
B) Changed Block Tracking (CBT).
C) vSphere Replication (VR).
D) Storage vMotion does not copy data.

Answer 1

Storage vMotion utilizes Network File Copy (NFC) and Changed Block Tracking (CBT) to efficiently copy virtual machine disk files between storage locations without downtime.

Step-by-step explanation:

Storage vMotion is a feature in VMware environments that allows for live migration of virtual machine disk files from one storage location to another without downtime. According to the latest capabilities of Storage vMotion, it can use two technologies to copy data from the source to destination:

• Network File Copy (NFC)
• Changed Block Tracking (CBT)

NFC is used to transfer data over the network, while CBT is leveraged to copy only the portions of the file that have changed since the last copy operation. This makes the process more efficient, especially for larger virtual disks or when bandwidth is limited. The correct answers are therefore A) Network File Copy (NFC) and B) Changed Block Tracking (CBT).
