In Apstra 5.1, the Active view represents the operational state of the deployed fabric (as opposed to the intended state being edited in Staged). Within Active, the Query function is designed for day-2 operations where an operator needs to quickly locate endpoint-related information and validate forwarding/neighbor state derived from the fabric. The query choices exposed in the UI are focused on operational lookup primitives rather than design objects. Specifically, Apstra supports querying MAC and ARP (and also VMs when virtual infrastructure integration is present).
MAC queries help identify where a Layer 2 endpoint is being learned in the fabric—useful for troubleshooting EVPN-VXLAN fabrics where MAC learning and advertisement can determine reachability and mobility behavior. ARP queries help identify IP-to-MAC bindings and validate whether hosts are being resolved correctly, which is critical when troubleshooting first-hop behavior (for example, IRB gateway adjacency, endpoint onboarding, or unexpected IP conflicts).
By contrast, “Virtual Network” and “Routing Zone” (VRF) are primarily design constructs managed in Staged and validated/assured by analytics and intent checks; they are not the direct query selectors in the Active > Query tool. Therefore, the two correct Active-query aspects from the given options are ARP and MAC.
