Examine this command, which executes successfully: cluster.addInstance(‘<user>@<host>:<port>’, {recoveryMethod: ‘clone’}) Which three statements are true? (Choose three.)
A.
The account used to perform this recovery needs the BACKUP_ADMIN privilege.
B.
A target instance must exist, then it will be provisioned with data from an instance already in the cluster and joined to the cluster.
C.
InnoDB tablespaces outside the datadir are able to be cloned.
D.
It is always slower than {recoveryMethod: ‘incremental’}.
E.
A new instance is installed, initialized, and provisioned with data from an instance already in the cluster and joined to the cluster.
F.
InnoDB redo logs must not rotate for the duration of the execution; otherwise, the recovery will fail.
A) clone pligin requires BACKUP_ADMIN
B) Instance must already exists and configure with clone plugin.
C) InnoDB outside of datadir can be clonned since it is remote clonning operation, not local.
D) not always.
C) Clone plugin or cluster replication do not INSTALL mysql instances. Instance must be already installed and running to join a cluster
F) Redo rotation is internally handled. No worries here .
sorry, keep changing my mind
A. true
B. False, target instance is not part of the cluster at first
C. True
D. false, Not always if there was no data in the first place.
E. True, initiated and previous node must exist.
F. False
A is right. Not E because is is already installed, just needs data copied.
