Which of the following is an example of dynamic credentialing in Vault?

Dynamic credentialing in HashiCorp Vault refers to the ability to generate credentials on-demand for accessing various services or platforms. This process enhances security by providing short-lived credentials that can be revoked when not needed, minimizing the risk of long-lived static credentials being compromised.

The example of dynamic credentialing for message queues fits this definition perfectly. In this case, Vault can dynamically generate credentials for accessing resources such as message queues, providing temporary access that is tailored to specific applications or users. These credentials can also be configured to have a limited lifespan, ensuring they are automatically invalidated after use.

Generating temporary SSH keys is an important feature, but it's more specific to SSH access rather than dynamic credentialing across a broader range of systems. Processing data in real-time does not inherently pertain to credential management, and storing static passwords is the opposite of dynamic credentialing, as it involves keeping fixed secrets instead of generating them on-the-fly.
