A network administrator is tasked with enabling SO-WAN at three branch locations. A topology has been provided for reference. For each site, the administrator is having issues bringing edges online, as another administrator has gone ahead and created a configuration ahead of time. The organization has several branch sites. One is an Internet-only site and two are Hybrid locations with both internet and MPLS. The last location is MPLS only. There are hub data center locations in this environment as well. Please refer to the topology.
After the network administrator has determined the problem with the Edge not being able to access the Internet, the administrator receives another error stating that the SD-WAN Orchestrator is still not reachable.
The VCO’s address is Amer-vcoOl.velocloud.net.
Refer to the Exhibit(s).

A . The SD-WAN Orchestrator specified is incorrect, and a new activation email needs to be sent.
B . The local firewall that the Edge uses to reach externally is blocking UDP Port 53 in both directions.
C . The SD-WAN Orchestrator has a limited 60-second window for the Edge to come online.
D . The SD-WAN Orchestrator is not being resolved for DN
