Answer options:
A.ReplicationLatency and PendingReplicationCount metrics provide information about the issue B.PendingReplicationLatency and ReplicationCount metrics provide information about the issue C.To resolve ReplicationLatency, verify that the read capacity units (RCUs) and write capacity units (WCUs) are identical for each of the replica tables D.To resolve ReplicationCount, verify that the provisioned write capacity settings are sufficient for your current workload. E.To resolve PendingReplicationLatency, verify that the read capacity units (RCUs) and write capacity units (WCUs) are identical for each of the replica tables F.To resolve PendingReplicationCount, verify that the provisioned write capacity settings are sufficient for your current workload.
