A Device Template in the Versa Networks platform is a standardized, reusable configuration applied to multiple branch devices to ensure consistency. The template workflow involves defining the fundamental characteristics of the device's role, which includes assigning functions to its physical interfaces (e.g., WAN or LAN ports) and configuring core SD-WAN services and policies, such as how to handle Direct Internet Access (DIA) for local internet breakout. These settings are central to the template's purpose of standardizing branch deployments.

B. Device Group: A Device Group is a logical container to which a template is applied, but the group itself is not an attribute configured within the template.

C. serial number: A serial number is a unique identifier for a specific physical device. Templates are generic and reusable, so they cannot contain device-specific unique information like a serial number.

1. Versa Networks

"Versa Director Configuration Guide" (Version 21.2.2):

Section: Device Templates

Page 112: The guide details the process of creating a device template. It explicitly shows steps for "Configuring Interfaces

" where an administrator assigns roles like WAN or LAN to the physical ports of the selected device model. This directly supports option A.

Section: Configuring Services in a Template

Page 125: This section describes how to enable and configure services within the template. It specifically mentions "Direct Internet Access (DIA)" as a service that is configured here

including the creation of associated policies. This supports option D.

2. Versa Networks

"Zero Touch Provisioning Deployment Guide" (Version 21.2.2):

Section: Onboarding a Device

Page 28: This document outlines the device onboarding workflow. It states

"During onboarding

the device is identified by its serial number and assigned to a Device Group. A pre-configured Device Template is then applied to the device." This clearly separates the serial number (C) and Device Group (B) as elements of the onboarding and assignment process

distinct from the content of the template itself.
