Several offices are connected with VPNs using static IPv4 routes. An administrator has been tasked with implementing OSPF to replace static routing. Which step is required to accomplish this goal?
The correct answer is D. Assign OSPF Area 0.0.0.0 to all Ethernet and tunnel interfaces.. Explanation/Reference: OSPF Area Types include the Backbone Area, Area 0, is the core of an OSPF network. The backbone has the reserved area ID of 0.0.0.0. All other areas are connected to it and all traffic between areas must traverse it. All routing between areas is distributed

Explanation
Explanation/Reference: OSPF Area Types include the Backbone Area, Area 0, is the core of an OSPF network. The backbone has the reserved area ID of 0.0.0.0. All other areas are connected to it and all traffic between areas must traverse it. All routing between areas is distributed through the backbone area. While all other OSPF areas must connect to the backbone area, this connection doesn't need to be direct and can be made through a virtual link.
