In Huawei Cloud, after uninstalling the cloud hard disk EVS from the elastic cloud server and mounting it to another elastic cloud server, the data on the cloud hard disk will be automatically reset…

Question

Options

• ATrue
• BFalse

• A
  15% (6)
• B
  85% (35)

Explanation

Option B is correct because EVS (Elastic Volume Service) disks are persistent block storage devices - their data exists independently of whichever ECS instance they are currently attached to. Detaching a disk and reattaching it to a different server does not trigger any data wipe; the contents remain exactly as they were when the disk was last unmounted. Option A is incorrect because automatic zeroing on remount does not occur in Huawei Cloud; if it did, EVS would be useless for common real-world scenarios such as migrating data between servers or recovering files after an instance failure.

Memory tip: Think of an EVS disk like a USB flash drive - unplugging it from one computer and plugging it into another leaves all your files untouched. The storage device holds the data, not the machine it is connected to.
