Justification |
Implication |
|---|---|---|---|
VCF-EXT-REQD-NET-001 |
Allocate statically assigned IP addresses and host names for all workload domain components. |
Ensures stability across the VMware Cloud Foundation instance, and makes it simpler to maintain, track, and implement a DNS configuration. |
You must provide precise IP address management. |
VCF-EXT-REQD-NET-002 |
Configure forward and reverse DNS records for all workload domain components. |
Ensures that all components are accessible by using a fully qualified domain name instead of by using IP addresses only. It is easier to remember and connect to components across the VMware Cloud Foundation instance. |
You must provide DNS records for each component. |
VCF-EXT-REQD-NET-003 |
Configure time synchronization by using an internal NTP time source for all workload domain components. |
Ensures that all components are synchronized with a valid time source. |
An operational NTP service must be available in the environment. |
VCF-EXT-REQD-NET-004 |
Set the NTP service for all workload domain components to start automatically. |
Ensures that the NTP service remains synchronized after you restart a component. |
None. |
