Question #: 18
Topic #: 2
I want to configure automatic migration of pinned services from an unhealthy server to another target in the cluster. I wish to configure consensus leasing for this purpose.
Which two statements are true in this scenario? (Choose two.)
A.
Set the cluster “Migration Basis” policy to Consensus.
B.
Migratable server should be associated with a node manager.
C.
Set the server “Migration Basis” policy to Consensus.
D.
A high availability database must be configured to manage consensus leasing information.
A: Using the Automatic Migration option requires setting a cluster’s Migration Basis policy to either Database or Consensus leasing.
C: Setting Migration Basis to Consensus leasing means that the member servers maintain leasing information in-memory, which removes the requirement of having a high-availability database to use leasing. This version of leasing requires that you use Node Manager to control servers within the cluster.
