Which two statements are true about deploying and using vSphere Replication? (Choose two.)

ESXi hosts managed by a single vCenter Server do not require a connection 'between the two' because there is only one vSphere Replication appliance managing all intra-site replication.

When sites are managed by different vCenter Server instances, the vSphere Replication appliances at each site must be paired via a site connection so replication traffic can flow between them. Without this connection, the source appliance cannot communicate with the target site's appliance to initiate or sustain replication.

Site Recovery Manager is an optional orchestration layer and is not required to deploy or use vSphere Replication - vSphere Replication can operate independently between two vCenter-managed sites.

Within a single vCenter Server instance, only one vSphere Replication appliance is required to manage and coordinate all replication tasks for the ESXi hosts under that vCenter's management domain.
