What is a limitation of the Databricks Secrets module?

The limitation of the Databricks Secrets module primarily revolves around the handling and exposure of sensitive information. In this context, the correct statement highlights that iterating through a stored secret can inadvertently reveal its contents in plain text. This means that while secrets are intended to secure sensitive information, improper handling or processes that expose secrets can lead to unintentional data leaks.

Secrets in Databricks are designed to be accessed securely through specific APIs and are meant to be managed carefully to maintain their confidentiality. However, if a user adopts a method that involves manipulating or iterating through secrets in a way that doesn't respect the intended encapsulation, it may expose the underlying sensitive information.

The other options touch on different aspects of how secrets are managed or perceived, but they do not directly describe the risk linked to secret exposure through iteration, making the statement about iteration the most relevant limitation regarding the security of the secrets mechanism within Databricks.
