Refer to the exhibit.

The exhibit indicates that the overlay-factories zone currently contains no SD-WAN member. In the GUI, zones containing members can be expanded to display their member interfaces; for example, HUB1 is expanded and shows HUB1-VPN1, HUB1-VPN2, and HUB1-VPN3. The overlay-factories entry does not display any member beneath it. The SD-WAN study material explains that an SD-WAN zone uses one or more interface members and that a zone used for traffic steering must contain at least one member. SD-WAN_7.6_Enterprise_Administr… The exhibit alone does not establish that overlay-factories can safely be deleted because other configuration references can prevent deletion. Likewise, virtual-wan-link is the default SD-WAN zone and cannot simply be treated as a removable user-created zone. Therefore, the directly supported conclusion is that overlay-factories has no member .
