In Huawei FusionCompute, the function that disk thin provisioning can achieve is? (Multiple choice)

Question

Options

• AVirtual storage thin provisioning has nothing to do with the operating system and hardware, so as
• BProvide virtual disk space monitoring and recycling functions
• CRecycling virtual machine disks in NTFS format is currently not supported
• DProvide early warning of data storage capacity, you can set the threshold, and generate an alarm

• A
  28% (15)
• B
  72% (39)

Explanation

Huawei FusionCompute's thin provisioning is a storage management feature that allocates disk space dynamically rather than up front, and options B, C, and D correctly describe its real capabilities and limitations.

Why B, C, D are correct:

• B is correct because thin provisioning inherently includes monitoring virtual disk usage and reclaiming space that is no longer actively used by VMs.
• C is correct because FusionCompute's disk recycling function has a known limitation - it cannot reclaim space from NTFS-formatted virtual disks, which is an important constraint to know.
• D is correct because thin provisioning in FusionCompute supports configurable capacity thresholds that trigger alarms when storage usage approaches defined limits, enabling proactive management.

Why A is wrong: Option A claims thin provisioning is independent of the OS and hardware, but this is false. As option C itself demonstrates, the guest OS file system format (NTFS vs. others) directly affects what thin provisioning can do - proving OS dependency is real.

Memory tip: Think of thin provisioning as a "smart landlord": it monitors space (B), warns you before the storage fills up (D), but has rules about what it can clean up - specifically, it can't reclaim NTFS-formatted disks (C). Option A breaks the analogy because the landlord absolutely cares what kind of tenant (OS/hardware) is in the unit.
