As part of a multisite Single Sign-On (SSO) deployment what two steps are required to ensure that a change to one Single Sign-On instance is propagated to the other instances? (Choose two.)

Scheduling a Replication Task on the primary SSO instance activates the synchronization mechanism that pushes identity and configuration data to all other instances in the topology. Without this task, changes made on the primary instance will not be propagated to peer instances.

Simply selecting the first instance during a subsequent installation does not configure replication - the explicit Linked-Mode option is the installer step that joins an instance to the SSO topology.

Selecting Linked-Mode during the installation of each additional SSO instance registers that instance into the existing SSO replication group, establishing the trust and communication channel required for data to flow between instances.

Synchronize to Active Directory controls how a single SSO instance pulls identity data from an AD source, and it has no effect on replication of SSO configuration between multiple SSO instances.
