vManage => NETCONF => vSmart => OMP => VEdge
While it's true that the vSmart controllers don't construct the data plane, answers A and B are clearly referencing vSmart.
D - every article I read and note I have suggests the answer is D, but for some reason I have a note that vManage leverages OMP to interface with vEdge and CertyIQ answer is also A. I am sure it is D

A. It leverages the overlay management protocol to interface with WAN Edge devices.
Explanation:
vManage is part of the Cisco SD-WAN solution, serving as the central management platform for configuring, monitoring, and managing SD-WAN edge devices. It uses the Overlay Management Protocol (OMP) to communicate with WAN Edge devices, ensuring that policies and configurations are distributed across the network.
Why other options are incorrect:
B: vManage does not support legacy routing protocols like OSPF directly. Instead, it focuses on SD-WAN protocols and policies.
C: vManage does not require a public IP address for WAN Edge devices to discover fabric components. Discovery typically occurs through a centralized orchestration system (vBond) using secure control plane protocols.
D: vManage does use NETCONF, but it primarily configures WAN Edge devices, not directly vSmart devices, which handle control plane policies. vSmart also communicates with WAN Edge devices using OMP.
For me its C bcoz vManage requires a public IP address to enable WAN Edge devices to discover and communicate with the components of the SD-WAN fabric. This is necessary for the establishment and management of the overlay network.
Option D:- This characteristic is not accurate. vManage primarily uses NETCONF for communication with WAN Edge devices, not vSmart devices, to configure and manage the overlay network.
A:- This characteristic is also not accurate. vManage primarily uses NETCONF, RESTCONF, and other protocols to communicate with WAN Edge devices, rather than overlay management protocols.
What you are referring to is the vBond: (from OCG page 635, vBond section) “It is the only device that must have a public IP address so that all SD-WAN devices in the network can connect to it”
Not D:
Cisco vSmart it is belongs to control plane and it is the brain of the solution. It is responsible for enforcing the policies centrally. These policies are created on the vManage.
OMP is really for vSmart a.k.a. SD-WAN Controllers to communicate with each other and the edge devices.
vManage (now SD-WAN Manager) uses NETCONF for its communications to the controllers, per the below link. Some quotes:
"The NETCONF protocol defines a mechanism through which network devices are managed and configured. The SD-WAN Manager uses NETCONF for communication with SD-WAN devices, primarily over DTLS/TLS, but there are a few situations where NETCONF is used natively before DTLS/TLS connections are formed."
"The Overlay Management Protocol (OMP), a TCP-based protocol similar to BGP, provides the routing for the overlay network. The protocol runs between SD-WAN Controllers and WAN Edge routers where control plane information is exchanged over secure DTLS or TLS connections."

It leverages the overlay management protocol to interface with WAN Edge devices1. Cisco vManage is a highly customizable dashboard that simplifies and automates the deployment, configuration, management, and operation for Cisco SD-WAN2. It uses the overlay management protocol (OMP) to communicate with vSmart controllers and WAN Edge devices, and to exchange routing, policy, and management information3.

vSmart controllers do not directly build the overlay network data plane. The data plane is constructed by the WAN Edge devices (such as vEdge routers), which establish encrypted tunnels between each other to carry traffic across the SD-WAN fabric. These tunnels form the overlay network data plane, allowing efficient and secure communication between sites. So, while vSmart controllers handle control plane functions, the data plane is established by the WAN Edge devices.
