Which of the following is NOT one of Vault's key features?

Vault is a tool focused primarily on securely storing and managing secrets in a highly controlled manner. One of its key features is Secure Secret Storage, which allows users to safely store sensitive information such as API keys, passwords, and certificates, ensuring that this data is not exposed or compromised.

Dynamic Secrets is another prominent feature, where Vault can generate secrets on-the-fly. This means that instead of using static and potentially long-lived credentials, Vault creates temporary credentials that can expire after a certain period, thereby reducing the risk of credential leakage.

Revocation is also a critical feature of Vault. This allows administrators to invalidate secrets or access tokens that may have been compromised or are no longer needed, ensuring that access is tightly managed and can be swiftly revoked if necessary.

In contrast, Data Visualization is not a core feature of Vault. While there may be associated tools that provide visualization of secrets usage or auditing data, Vault itself does not focus on this aspect as part of its primary functionalities. Vault emphasizes security and management of secrets rather than providing dashboards or visual representations of data.
