When registering Cisco UCS Manager to Cisco UCS Central, there are several prerequisites that need to be met. The registration process uses HTTPS and relies on specific network ports and protocols to communicate between the two devices. In this scenario, the engineer can ping Cisco UCS Central from UCS Manager, but the registration still fails. This indicates that there is a network connectivity issue between the two devices, which can be resolved by performing the following actions:

A. Synchronize the date and time to NTP for Cisco UCS Central and the Cisco UCS domains.

One of the most common causes of registration failure is the difference in time between the two devices. Therefore, it is recommended to configure Network Time Protocol (NTP) on both Cisco UCS Manager and Cisco UCS Central to ensure that the time is synchronized. This helps to ensure that the communication between the two devices is not hindered by discrepancies in the time.

B. Allow port 9443 between Cisco UCS Manager and Cisco UCS Central.

Another common cause of registration failure is the blocked network ports between the two devices. In this case, the engineer should allow port 9443 between Cisco UCS Manager and Cisco UCS Central. Port 9443 is used for HTTPS traffic between Cisco UCS Manager and Cisco UCS Central. By allowing this port, the communication between the two devices is no longer restricted, and registration can proceed.

Therefore, the correct answers to this question are A and E: synchronize the date and time to NTP for Cisco UCS Central and the Cisco UCS domains, and allow port 9443 between Cisco UCS Manager and Cisco UCS Central.
