1. Configuration of New DNS Server
1.1. Prerequisites
The new DNS server to be configured should be reachable from SDDC components.
DNS resolution (forward and reverse lookup) for all management VMs and ESXi hosts in place
All SDDC components should be reachable from SDDC manager.
All SDDC components state should be "ACTIVE" in VCF inventory.
1.2. Steps
- Validate the DnsConfiguration input before configuration.

In case of no errors in the validation , the "executionStatus" is "COMPLETED" and "resultStatus" is "SUCCEEDED".
In case of errors in the input specification, the "executionStatus" is "COMPLETED" and "resultStatus" is "FAILED".
Note : Make changes to the input specification and re-validate using a new API invocation.
- Trigger the task using the valid input specification.

2. Configuration of New NTP Server
2.1. Prerequisites
The new NTP server(s) to be configured should be reachable from SDDC components.
The new NTP server(s) should be able to do NTP sync from SDDC Manager.
All SDDC components should be reachable from SDDC manager.
All SDDC components state should be active as per SDDC Manager.
The new server should be NTP synced from the SDDC Manager.
2.2. Steps
- Perform the validation step for the desired NTP configuration before applying the same.
