In Huawei Fusion Computerr, which of the following descriptions about hot migration is incorrect?

Question

Options

• AUse memory data fast copy and shared storage technology during virtual machine live migration to
• BHot migration includes virtual machine hot migration and disk hot migration
• CThe types of virtual machine live migration are divided into changing the host, changing the data
• DStorage live migration can only be migrated within the same storage device under storage

• C

• D

Explanation

Option D is the incorrect statement because storage live migration (disk hot migration) in Huawei FusionCompute is not restricted to the same storage device - it can migrate virtual disk data across different storage devices, which is precisely its key value in real-world scenarios like storage upgrades or load balancing.

Option A is correct: live migration does use memory fast-copy combined with shared storage technology to transfer a running VM's state with minimal downtime. Option B is correct: hot migration is an umbrella term covering both virtual machine live migration (moving a VM's compute workload between hosts) and disk/storage live migration (moving disk data while the VM runs). Option C is correct: VM live migration types are categorized by what changes - the host (compute migration), the datastore (storage migration), or both simultaneously.

Memory tip: Think of the word "only" in option D as a red flag - in exam questions about migration technologies, absolute restrictions like "only within the same device" are almost always false, because the entire purpose of storage live migration is cross-device flexibility.
