An organization recently introduced a new network segment. Administrators confirmed that each system in the new segment has the correct addresses, but resources in the new segment cannot communicate with workloads in a separate segment. Which approach best resolves the connectivity challenge?
Open or close specific firewall rules for that segment
Configure DNS records for hosts in the new segment
Create or update a routing entry that forwards traffic for the new segment
Change the addresses of the systems in the new segment
Adding a new entry to direct traffic for the new segment ensures that packets can travel between segments. Adapting firewall rules may help if there's a policy issue, but it will not help if there is no valid path. Changing DNS settings would correct name resolution but not solve the underlying traffic path issue. Adjusting the default gateway may be required if the default route is incorrect, yet it is not as direct as assigning a specific path through an updated routing record.
