Which type of Vault replication copies all data from Vault, including K/V data, policies, and client tokens?
A . DR replication
B . performance replication
C . failover replication
D . online replication
Answer: A
Explanation:
Vault Enterprise supports multi-datacenter deployment where you can replicate data across data centers for performance as well as disaster recovery.
In DR replication, secondary clusters do not forward service read or write requests until they are elevated and become a new primary.
DR replicated cluster will replicate all data from the primary cluster, including tokens. A performance replicated cluster, however, will not replicate the tokens from the primary, as the performance replicated cluster will generate its own client tokens for requests made directly to it.
In performance replication, secondaries keep track of their own tokens and leases but share the underlying configuration, policies, and supporting secrets (K/V values, encryption keys for transit, etc).
Note: Failover and Online replication, there is no such replication exist in hashicorp vault.
