What is one of the benefits of using dynamic secrets provided by Vault?

• A. They are completely static and never change
• B. They expire after a specified time
• C. They can only be generated manually
• D. They are always stored unencrypted

Answer: (B)

Using dynamic secrets provided by HashiCorp Vault offers several advantages, one of which is that they expire after a specified time. This feature enhances security by limiting the lifespan of sensitive credentials. Dynamic secrets are generated on-the-fly when requested and are tied to specific requests or sessions, ensuring that they are not persistent. Once they reach their expiration time, they are automatically revoked, meaning they cannot be reused or exploited after that period. This approach significantly reduces the window of opportunity for potential attackers who might intercept or misuse the credentials. The other options do not accurately represent the characteristics of dynamic secrets. For instance, they are not static or manually generated, and they are always stored securely, typically in an encrypted format, rather than unencrypted. This ephemeral nature of dynamic secrets aligns well with modern security practices, making them a valuable feature in Vault's secret management capabilities.
