Question
Which statement is true of persistent disks?Persistent disks are always HDDs (magnetic spinning disks).Persistent disks are physical hardware devices connected directly to VMs.Persistent disks are encrypted by default.Once created, a persistent disk cannot be resized.
Solution
The statement that is true of persistent disks is: "Persistent disks are encrypted by default."
Here's why:
-
Persistent disks are not always HDDs (magnetic spinning disks). They can also be SSDs (Solid State Drives).
-
Persistent disks are not physical hardware devices connected directly to VMs. They are network storage devices that can be attached to VMs.
-
Persistent disks are indeed encrypted by default. Google encrypts all data at rest in Google Cloud Storage, including persistent disks.
-
Once created, a persistent disk can be resized. You can increase the size of a persistent disk without needing to restart the associated instances.
