A routing protocol's internal adjacency does not guarantee a usable route for unknown destinations; a valid and authorized default egress is needed. Configure a controlled default route and distribute it only where the campus topology requires. would address default-route propagation, but the reported facts instead point to AP country-code and RF regulatory setting. That change would leave the actual requirement unresolved.

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 AP country-code and RF regulatory setting condition.

The alternative targets central configuration audit, where management intent, synchronization status and the running device state are distinct; failed changes or local overrides can leave unintended effective configuration. It does not establish the intended AP country-code and RF regulatory setting behavior described in the scenario.

That action—Bind returned authorization roles to correct local or downloadable enforcement behavior—is relevant to dynamic role enforcement. A RADIUS Access-Accept alone does not prove the switch or gateway applied the intended role policy to user sessions. It does not correct the observed corporate EAP-TLS SSID condition.

A functioning Ethernet link does not establish cloud-management ownership; onboarding requires the correct device identity, management association and supported connectivity. Register and assign each device to the correct authorized Central organization and inventory before configuring it. would address central device inventory onboarding, but the reported facts instead point to corporate EAP-TLS SSID. That change would leave the actual requirement unresolved.

The alternative targets RADIUS shared-secret consistency, where RADIUS exchanges rely on correctly configured shared secrets and client definitions; basic IP reachability does not establish a valid AAA relationship. It does not establish the intended corporate EAP-TLS SSID behavior described in the scenario.

The alternative targets acceptance of WLAN security and mobility, where an AP advertising a network does not prove that clients can authenticate, receive approved privileges or maintain application continuity while moving. It does not establish the intended RADIUS service resilience behavior described in the scenario.

That action—Plan an RF site survey that incorporates floor materials, interference and required client behavior—is relevant to RF survey and building materials. Propagation and attenuation vary with walls, shelving and device environments; a diagram alone cannot establish coverage or service quality. It does not correct the observed RADIUS service resilience condition.

Product capabilities and configuration syntax depend on supported hardware and software releases; a feature described in another model's guide may be unavailable. Verify platform model, software release and licensed-feature compatibility in the design. would address firmware feature-support planning, but the reported facts instead point to RADIUS service resilience. That change would leave the actual requirement unresolved.

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 duplex and speed negotiation condition.

A healthy neighbor relationship does not imply every desired route is present; network statements, redistribution and policy can omit a prefix. Verify that the intended connected subnet is advertised and permitted by OSPF configuration and filters. would address OSPF prefix advertisement omission, but the reported facts instead point to duplex and speed negotiation. That change would leave the actual requirement unresolved.

The alternative targets missing trunk VLAN, where a frame cannot traverse a trunk on which its tagged VLAN is not allowed; local endpoint configuration can be fully correct. It does not establish the intended duplex and speed negotiation behavior described in the scenario.

The alternative targets baseline before optimization, where optimization claims require equivalent loads, test methods and service metrics before and after; otherwise changes in demand confound comparison. It does not establish the intended optimization with rollback behavior described in the scenario.

That action—Retain mandatory authorization and segmentation controls while optimizing forwarding or QoS—is relevant to security-preserving optimization. A performance gain is not acceptable if it weakens required access boundaries; improvements must meet both service and security acceptance criteria. It does not correct the observed optimization with rollback condition.

Subscriber tracking lets a switch direct multicast toward active receivers instead of flooding every port, protecting shared access bandwidth. Enable and validate IGMP-based multicast receiver forwarding where supported. would address multicast traffic scope, but the reported facts instead point to optimization with rollback. That change would leave the actual requirement unresolved.

That result—The stack reports the expected active members and resilient forwarding across an intended member failure—concerns VSF member management. VSF presents supported physical members as a virtual switch while retaining operational requirements for healthy stacking links and member state. It can be healthy even while the current VSX keepalive isolation problem remains.

This would validate VSX peer synchronization, not VSX keepalive isolation. VSX peers retain independent control planes and only designated supported feature sets synchronize; unchecked settings may diverge. It is therefore insufficient acceptance evidence for the reported condition.

VLAN configuration creates Layer 2 separation; inter-subnet communication requires appropriate Layer 3 interfaces, addressing and policy. The indicated result—representative clients can reach their configured gateways and only permitted inter-VLAN routes operate—checks a different mechanism and would not confirm the required VSX keepalive isolation outcome.

That result—The collector receives attributable device events with usable timestamps and appropriate retention settings—concerns syslog event centralization. Centralized time-stamped records preserve context for multi-device analysis and avoid relying on volatile local event buffers. It can be healthy even while the current central client health visibility problem remains.

This would validate API paging and rate limits, not central client health visibility. Management APIs may return segmented data or throttle callers, so automation must recognize incomplete and transient outcomes instead of silently succeeding. It is therefore insufficient acceptance evidence for the reported condition.

A capture tool sees only frames delivered to it; a correctly scoped mirror copies relevant ingress or egress traffic without changing production forwarding. The indicated result—the capture workstation receives the expected test flow and does not inadvertently mirror unrelated sensitive traffic—checks a different mechanism and would not confirm the required central client health visibility outcome.

Repeated link transitions and frame errors point to Layer 1 quality or negotiation rather than an unseen WLAN authentication issue. The indicated result—the repaired link remains stable under load and physical error counters stop increasing unexpectedly—checks a different mechanism and would not confirm the required duplex and speed negotiation outcome.

That result—Policy logs or counters identify the matching rule and the repaired rule permits only the approved service—concerns ACL deny versus service outage. An ACL can block selected Layer 4 flows while other connectivity remains healthy; removing all controls is an unsafe shortcut. It can be healthy even while the current duplex and speed negotiation problem remains.

This would validate optics compatibility and signal levels, not duplex and speed negotiation. An unsupported or poorly coupled optical path prevents reliable Ethernet signalling regardless of correct routing or authentication configuration. It is therefore insufficient acceptance evidence for the reported condition.

That result—The revised performance baseline includes recent peak usage and documented changes to client mix, application load and network capacity—concerns periodic baseline refresh. A fixed historical baseline can become misleading as workload mix and client capability change; thresholds should reflect current accepted operating conditions. It can be healthy even while the current uplink oversubscription tuning problem remains.

This would validate multicast traffic scope, not uplink oversubscription tuning. Subscriber tracking lets a switch direct multicast toward active receivers instead of flooding every port, protecting shared access bandwidth. It is therefore insufficient acceptance evidence for the reported condition.

QoS can prioritize selected packets when contention occurs but cannot create bandwidth; correct queue treatment reduces latency for critical applications. The indicated result—under a reproducible congestion test, voice latency and jitter meet targets while other traffic remains serviceable—checks a different mechanism and would not confirm the required uplink oversubscription tuning outcome.

This would validate syslog event centralization, not configuration revision and approval history. Centralized time-stamped records preserve context for multi-device analysis and avoid relying on volatile local event buffers. It is therefore insufficient acceptance evidence for the reported condition.

API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. The indicated result—a scoped automation token reads intended resources, fails prohibited write operations and is absent from code repositories—checks a different mechanism and would not confirm the required configuration revision and approval history outcome.

That result—A controlled test retrieves all expected records and handles pagination or retryable response codes without data loss—concerns API paging and rate limits. Management APIs may return segmented data or throttle callers, so automation must recognize incomplete and transient outcomes instead of silently succeeding. It can be healthy even while the current configuration revision and approval history problem remains.

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.
