In which of the following SaaS apps can you protect data at rest via Zscaler...

Out-of-band CASB protects data at rest in supported SaaS repositories by connecting to the provider through APIs. Google Drive is a supported cloud storage/collaboration application where files, sharing links, and sensitive content can be inspected and remediated after storage. Option C (Google Drive) is correct because Google Drive is a SaaS data-at-rest use case.

Why the other options are incorrect:

A. Yahoo Mail: Yahoo Mail is webmail. It can be controlled by ZIA, but the scenario’s target is Google Drive cloud storage.

B. Twitter: Twitter/X is a social media service. It is not the cloud file-sharing destination used in the scenario.

D. Facebook: Facebook is a social platform. It does not represent the Google Drive storage action being tested.
