What is a description of vManage NMS?
The correct answer is B. A cluster requires device templates to be created on and attached to the same server. In a vManage cluster, device templates must be created on and attached to the same vManage server instance, which is a key operational constraint of the clustering architecture.

Why each option
In a vManage cluster, device templates must be created on and attached to the same vManage server instance, which is a key operational constraint of the clustering architecture.
vManage is accessible via VPN 512 (out-of-band management) but is not restricted exclusively to VPN 512; in-band management access is also possible.
In a vManage cluster, each node manages its own subset of attached devices, and device templates must be created and applied on the same cluster node to which the devices are attached. This per-node affinity constraint affects how template management and device attachment are distributed across cluster members.
vManage is a dedicated network management system controller appliance or VM, not a software process running on a WAN Edge router.
A vManage cluster requires a minimum of three nodes - an odd number to support proper quorum and consensus - not a minimum of two.
