The correct answers are A, B, and E . Versa Operating System, or VOS , is the software platform used for Versa SD-WAN branch and headend functions. Versa troubleshooting documentation explicitly refers to common runtime state across SD-WAN Controller, branch, and hub devices , confirming that VOS is used for Controller and branch-style SD-WAN roles. Versa monitoring documentation also lists SD-WAN branches, SD-WAN Controller nodes, SD-WAN hubs, vCPEs, and uCPEs as assets that are monitored and managed in Versa Director, which aligns with VOS being used as a branch/edge and controller platform.
VOS can also act as a uCPE platform . Versa documentation includes procedures to configure uCPE on a VOS device, showing that VOS can host or support uCPE deployment use cases.
The originally provided answer A, C, D is not correct. A Log Collector or log forwarder function belongs to the Versa Analytics architecture, not the VOS branch role; Versa’s design guide states that the log forwarder is part of the Versa Analytics node or can run as a standalone log-forwarder server. A Zookeeper arbiter is also not a standard VOS SD-WAN device role in this context.
