AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Versioning - Hands On

The video tutorial explains how to enable and manage bucket versioning in AWS S3. It covers uploading files before and after enabling versioning, demonstrating how version IDs are assigned. The tutorial also discusses delete markers, their role in simulating file deletion, and how to permanently delete files. Finally, it explains the implications of disabling versioning and how it affects file versions.

What happens to the version ID of an object uploaded before enabling versioning?

• It does not get a version ID.

• It is assigned the current timestamp as version ID.

• It is assigned a version ID of null.

• It is assigned a random version ID.

What occurs when a file is uploaded again after enabling versioning?

• The file is uploaded without a version ID.

• The file is rejected due to duplication.

• A new version ID is assigned, and previous versions are retained.

• The previous version is overwritten.

What is the purpose of a delete marker in AWS versioning?

• To make it appear as if the file is deleted without actually removing it.

• To archive the file for later retrieval.

• To indicate the file is temporarily unavailable.

• To permanently delete the file.

What is the effect of permanently deleting a specific version ID?

• It removes the delete marker.

• It archives the object version.

• It adds a new delete marker.

• It permanently removes the object version.

How can a file be restored after a delete marker is added?

• By enabling versioning again.

• By uploading the file again.

• By deleting the delete marker.

• By contacting AWS support.

What happens to new objects when versioning is suspended?

• They overwrite existing objects.

• They are not stored in the bucket.

• They are assigned a random version ID.

• They are assigned a version ID of null.

Why is versioning important in preventing unintended deletions?

• It prevents any deletions from occurring.

• It encrypts the files for security.

• It allows for automatic backups.

• It enables the restoration of previous versions.
