What type of replication is used for vault availability in a Cold state?

The scenario describes a cold state for vault availability, which typically refers to a situation where the data needs to be replicated to ensure that it can be accessed securely even when the primary vault is unavailable. In this context, secure replication of encrypted data is the correct choice because it highlights the essence of maintaining data integrity and confidentiality during the replication process.

When data is replicated in a cold state, it involves transferring encrypted information to ensure that sensitive data remains secure against unauthorized access. This method safeguards the data during transmission and storage in secondary vaults, allowing organizations to meet compliance requirements and protect against data breaches.

In contrast, the other options suggest different methods or access types that may not specifically address the need for secure replication in a cold state. For example, read-only access to local data does not provide a mechanism for redundancy or secure data transfer. High Availability (HA) clustering typically involves active server operations to maintain immediate access and redundancy, which doesn't align with the cold state concept. Lastly, multiple concurrent server operations imply simultaneous processes or transactions that do not focus on the secure replication of data, especially when handling data in a cold state scenario.
