Which two components are included in a vManage high-availability cluster architecture? (Choose two.)

A vManage high-availability (HA) cluster architecture includes a network configuration system and an application server. The network configuration system is responsible for managing and distributing configurations to devices in the SD-WAN fabric, ensuring consistent policy enforcement. The application server handles the vManage GUI, API interactions, and various operational tasks, providing the user interface and programmatic access to the SD-WAN solution. WAN Edge routers are part of the data plane, not the vManage control plane HA cluster. NAT routers are network infrastructure components, not specific to the vManage HA cluster. While vManage uses messaging for internal communication, "messaging server" is not a distinct, top-level component defining the HA architecture in the same way as the network configuration system and application server.
