The statement is false. The Vault encryption key is not stored in Vault’s backend storage, but rather in Vault’s memory. The Vault encryption key is the key that is used to encrypt and decrypt the data that is stored in Vault’s backend storage, such as secrets, tokens, policies, etc. The Vault encryption key is derived from the master key, which is generated when Vault is initialized. The master key is split into unseal keys using Shamir’s secret sharing algorithm, and the unseal keys are distributed to trusted operators. To start Vault, a quorum of unseal keys is required to reconstruct the master key and derive the encryption key. The encryption key is then kept in memory and used to protect the data in Vault’s backend storage. The encryption key is never written to disk or exposed via the API. References: Seal/Unseal | Vault | HashiCorp Developer, Key Rotation | Vault | HashiCorp Developer

The payload.json file that has the correct contents is C. This file contains a JSON object with a single key, “plaintext”, and a value that is the base64-encoded string of the data to be encrypted. This is the format that the Vault API expects for the transit encrypt endpoint1. The other files are not correct because they either have the wrong key name, the wrong value format, or the wrong JSON syntax.

The replication methods available in Vault Enterprise are performance replication and disaster recovery replication. These methods allow critical data to be replicated across clusters to support horizontally scaling and disaster recovery workloads.

• Performance replication enables a primary cluster to replicate data to one or more secondary clusters, which can handle client requests and improve performance and availability. Performance replication replicates most Vault data, such as secrets, policies, auth methods, and leases, but not tokens. Performance secondaries generate their own tokens and leases, which are not replicated back to the primary. Performance replication also supports filtering, which allows selective replication of data based on namespaces or paths.
• Disaster recovery replication enables a primary cluster to replicate data to one or more secondary clusters, which act as standby clusters in case of a failure or outage of the primary. Disaster recovery replication replicates all Vault data, including tokens and leases, and maintains the same configuration and state as the primary. Disaster recovery secondaries do not handle client requests, but they can be promoted to a primary in a disaster recovery scenario. References: Replication - Vault Enterprise | Vault | HashiCorp Developer, Performance Replication - Vault Enterprise | Vault | HashiCorp Developer, Disaster Recovery Replication - Vault Enterprise | Vault | HashiCorp Developer
