Bdataset

Csnapshot

Dclone

Epool

Show Suggested Answer

Suggested Answer: C

A snapshot is a read-only point-in-time copy of a file system. The copy-on-write design

of ZFS makes them essentially ''free'' - They are space efficient and instantaneous, providing an invaluable part of backup strategies and synchronizing data between systems.

Incorrect:

Not A: A ZFS vdev (aka 'virtual device') is either:

a single disk, or

two or more disks that are mirrored, or

a group of disks that are organized using RAID-Z.

There are also special kinds of vdevs like hot-spares, ZIL or cache devices, etc.

Not D:

Clones are writeable snapshots, ideal for storing many private

copies of shared data for operations such as data migration, test

and development, or backup.

Ahh, C) snapshot, of course! I should have known that. It's like the file system version of a selfie - quick, easy, and not too demanding on resources.

This question is a real brain-teaser. I'm going to throw caution to the wind and say E) pool, just to see if I can stump the test-makers.

I'll go with D) clone. It sounds like it could be a read-only copy, but I'm not entirely sure. Perhaps I should have paid more attention in my file system management class.

I believe it's C) snapshot because clones are independent copies that do consume additional space.

Definitely C) snapshot. I've used these before, and they're super handy for quickly preserving the state of a file system without taking up much space.

Hmm, this is a tricky one. I'm guessing C) snapshot is the correct answer, since it fits the description of a read-only copy that's quick and easy to create.
