What is Object Versioning in Google Cloud Storage?

Object Versioning is a feature that keeps multiple versions of an object in a storage bucket. When enabled, every time you overwrite or delete an object, the old version is saved and can be restored later.

How does enabling Object Versioning help protect data?

It protects data by keeping previous versions of objects. If you accidentally delete or overwrite a file, you can recover the older version instead of losing it permanently.

What happens when you delete an object in a bucket with Object Versioning enabled?

The object is not permanently deleted. Instead, a 'delete marker' is added, and the old versions remain stored. You can restore the object by removing the delete marker or accessing previous versions.

How do you enable Object Versioning on a Google Cloud Storage bucket?

You enable it by setting the bucket's versioning configuration to 'enabled' using the Cloud Console, gsutil command, or API. For example, with gsutil: `gsutil versioning set on gs://your-bucket-name`.

What is a practical example of using Object Versioning?

Imagine you have a photo album stored in a bucket. If you accidentally overwrite a photo, Object Versioning lets you restore the original photo from an earlier version, preventing data loss.

What does Object Versioning do in Google Cloud Storage?

A Keeps multiple versions of objects when they are changed or deleted

B Deletes objects permanently immediately

C Compresses objects to save space

D Encrypts objects automatically

Object Versioning keeps old versions of objects so you can recover them if overwritten or deleted.

How can you enable Object Versioning on a bucket?

A By uploading a special file

B By setting the bucket's versioning configuration to 'enabled'

C By deleting the bucket

D By changing the bucket's location

You enable Object Versioning by setting the bucket's versioning to 'enabled' via console, gsutil, or API.

If you delete an object in a versioned bucket, what happens?

A A delete marker is added and old versions remain

B The object is permanently removed immediately

C The bucket is deleted

D The object is moved to another bucket

Deleting an object adds a delete marker; previous versions are kept for recovery.

Why is Object Versioning useful?

A It reduces storage costs

B It speeds up file uploads

C It helps recover accidentally deleted or overwritten files

D It automatically backs up your entire project

Object Versioning helps recover files by keeping older versions.

Which command enables Object Versioning using gsutil?

A gsutil enable version gs://bucket-name

B gsutil set versioning true gs://bucket-name

C gsutil bucket version on

D gsutil versioning set on gs://bucket-name

The correct gsutil command is `gsutil versioning set on gs://bucket-name`.
