An engineer added more APs to newly renovated areas in building.

The Out-of-Sync alarms in Cisco Prime Infrastructure typically indicate that there is a discrepancy between the configuration of the APs as known by Prime Infrastructure and their actual configuration. To resolve this issue, the engineer can either manually synchronize the APs from Cisco Prime Infrastructure (A) or enable automatic synchronization on Cisco Prime Infrastructure © to ensure that the AP configurations are updated automatically. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
