That result—The repaired link remains stable under load and physical error counters stop increasing unexpectedly—concerns physical layer link fault. Repeated link transitions and frame errors point to Layer 1 quality or negotiation rather than an unseen WLAN authentication issue. It can be healthy even while the current spanning-tree blocked forwarding problem remains.

This would validate access VLAN misassignment, not spanning-tree blocked forwarding. The VLAN used for an untagged or dynamically authorized session determines its broadcast and DHCP context; physical link state is not enough. It is therefore insufficient acceptance evidence for the reported condition.

Separate VRFs maintain distinct forwarding information bases; routes visible in one context do not automatically apply in another. The indicated result—the correct VRF has an installed destination route and permitted traffic uses the intended next hop—checks a different mechanism and would not confirm the required spanning-tree blocked forwarding outcome.

This would validate configuration revision and approval history, not API paging and rate limits. Auditability requires associating control-plane changes with an identity, time, reason and prior state, not just the new value. It is therefore insufficient acceptance evidence for the reported condition.

Recovery decisions based on elapsed time and service impact are more reliable than an operator's improvised judgment under incident pressure. The indicated result—change records show a clear checkpoint decision and a restore test when acceptance thresholds are not met—checks a different mechanism and would not confirm the required API paging and rate limits outcome.

That result—A scoped automation token reads intended resources, fails prohibited write operations and is absent from code repositories—concerns REST API authentication boundaries. API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. It can be healthy even while the current API paging and rate limits problem remains.

RADIUS exchanges rely on correctly configured shared secrets and client definitions; basic IP reachability does not establish a valid AAA relationship. Match the network access device's RADIUS client settings and shared secret to the authorized server definition. would address RADIUS shared-secret consistency, but the reported facts instead point to MAC authentication for headless devices. That change would leave the actual requirement unresolved.

That action—Validate client security-mode capability and stage a compatible secure WLAN migration—is relevant to WPA3 and legacy clients. WLAN security changes can exclude devices with unsupported cipher, authentication or protected-management-frame capabilities. It does not correct the observed MAC authentication for headless devices condition.

The alternative targets OSPF adjacency prerequisites, where OSPF adjacency depends on compatible peer parameters and reachable interfaces; a live link is insufficient when control-plane settings disagree. It does not establish the intended MAC authentication for headless devices behavior described in the scenario.

The alternative targets poE budget planning, where available port count does not establish available power; a switch can have free interfaces while its aggregate PoE budget is exhausted. It does not establish the intended critical application traffic profile behavior described in the scenario.

The low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. Translate business requirements into measurable network acceptance criteria before selecting configurations. would address campus requirements and acceptance criteria, but the reported facts instead point to critical application traffic profile. That change would leave the actual requirement unresolved.

That action—Assign clear access, aggregation and routing roles and validate their traffic and scale requirements—is relevant to access/distribution hierarchy. A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. It does not correct the observed critical application traffic profile condition.

VSF forms a virtual switch with supported stacking members; VSX coordinates two peers while retaining separate control planes, so support and failure domains differ. The indicated result—the selected hardware and architecture documentation match the intended stacking or peer-control behavior and supported model family—checks a different mechanism and would not confirm the required VLAN and subnet segmentation outcome.

This would validate acceptance of WLAN security and mobility, not VLAN and subnet segmentation. An AP advertising a network does not prove that clients can authenticate, receive approved privileges or maintain application continuity while moving. It is therefore insufficient acceptance evidence for the reported condition.

That result—A link or peer failure test keeps supported endpoint traffic forwarded over the surviving upstream path—concerns dual-homed downstream aggregation. Hardware redundancy is ineffective if every downstream path still depends on one forwarding node or unsound Layer 2 topology. It can be healthy even while the current VLAN and subnet segmentation problem remains.

That result—An unauthorized BPDU on the protected access port triggers the configured protective behavior without altering the campus root—concerns BPDU Guard at edge ports. Edge ports should not accept topology-control messages from unauthorized bridges; BPDU Guard can protect the switching domain by restricting offending links. It can be healthy even while the current native VLAN alignment problem remains.

This would validate spanning-tree loop prevention, not native VLAN alignment. Uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It is therefore insufficient acceptance evidence for the reported condition.

Management intent, synchronization status and the running device state are distinct; failed changes or local overrides can leave unintended effective configuration. The indicated result—the audit reports no unresolved deployment errors and the running device setting matches approved intent—checks a different mechanism and would not confirm the required native VLAN alignment outcome.

The alternative targets trunk allowed VLAN list, where a VLAN's existence on each switch is insufficient if the inter-switch trunk omits it, so frames cannot traverse the missing membership. It does not establish the intended classic Central site versus group behavior described in the scenario.

That action—Supply and verify unique per-device variables before applying a reusable provisioning template—is relevant to template variable rendering. Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. It does not correct the observed classic Central site versus group condition.

A device must receive intent appropriate to its product family and role; the wrong group or persona can apply unrelated settings or reject configuration. Assign devices to compatible Central groups or functions before applying shared configurations. would address device group selection, but the reported facts instead point to classic Central site versus group. That change would leave the actual requirement unresolved.

That result—Updated uplink capacity and measured utilization support the busiest expected periods without material drops—concerns uplink oversubscription tuning. Access port sum can greatly exceed distribution bandwidth, so congestion and burst tolerance must be planned rather than inferred from port speed labels. It can be healthy even while the current voice queuing under load problem remains.

This would validate transmit-power balance, not voice queuing under load. Downlink strength from a powerful AP does not increase client transmit capability; asymmetric links and oversized cells can harm roaming. It is therefore insufficient acceptance evidence for the reported condition.

Blindly trusting endpoint markings lets untrusted traffic dominate queues; classification must reflect approved service importance. The indicated result—queue counters and packet markings confirm trusted voice traffic receives priority while guest bulk flows remain appropriately classified—checks a different mechanism and would not confirm the required voice queuing under load outcome.

Access port sum can greatly exceed distribution bandwidth, so congestion and burst tolerance must be planned rather than inferred from port speed labels. The indicated result—updated uplink capacity and measured utilization support the busiest expected periods without material drops—checks a different mechanism and would not confirm the required storm control tuning outcome.

That result—Capture and counters show multicast delivery to joined receiver ports without excess traffic to nonmembers—concerns multicast traffic scope. Subscriber tracking lets a switch direct multicast toward active receivers instead of flooding every port, protecting shared access bandwidth. It can be healthy even while the current storm control tuning problem remains.

This would validate channel reuse planning, not storm control tuning. Co-channel neighbors share airtime when within interference range; thoughtful reuse can reduce contention without simply widening channels. It is therefore insufficient acceptance evidence for the reported condition.

That result—Pilot results meet both targeted improvement and adjacent-service safeguards before broader deployment—concerns optimization with rollback. A change may help one metric while degrading another; phased deployment and recovery thresholds protect production service continuity. It can be healthy even while the current baseline before optimization problem remains.

This would validate periodic baseline refresh, not baseline before optimization. A fixed historical baseline can become misleading as workload mix and client capability change; thresholds should reflect current accepted operating conditions. It is therefore insufficient acceptance evidence for the reported condition.

Fast reliable handoff requires compatible client capabilities, adequate AP overlap and secure authentication continuity rather than just increasing bandwidth. The indicated result—a walk test records acceptable handoff delay and voice packet loss under normal movement paths—checks a different mechanism and would not confirm the required baseline before optimization outcome.

That action—Inspect STP port roles and topology before overriding a blocked redundant link—is relevant to spanning-tree blocked forwarding. A correctly blocked path may be essential loop prevention; unblocking without analyzing topology can trigger broadcasts and MAC instability. It does not correct the observed captive portal redirect fault condition.

Cloud device online status does not prove every radio is active or that target clients can discover the selected channel. Check AP radio administrative state, band and regulatory channel support. would address AP radio disabled or unsupported channel, but the reported facts instead point to captive portal redirect fault. That change would leave the actual requirement unresolved.

The alternative targets 802.1X supplicant disabled, where an authentication server cannot authorize an endpoint that never initiates the intended EAP handshake on the controlled link. It does not establish the intended captive portal redirect fault behavior described in the scenario.
