The alternative targets static route and next-hop reachability, where a route must identify the desired prefix and a valid forwarding path; a configured but unresolved next hop does not deliver packets. It does not establish the intended SVI inter-VLAN gateway behavior described in the scenario.

That action—Keep an appropriate spanning-tree or supported loop-free design across redundant Layer 2 paths—is relevant to spanning-tree loop prevention. Uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It does not correct the observed SVI inter-VLAN gateway condition.

A virtual first-hop gateway provides a stable client next-hop while authorized peers coordinate active forwarding after failure. Configure a supported redundant virtual gateway mechanism with correct priorities and tracking. would address VRRP gateway resilience, but the reported facts instead point to SVI inter-VLAN gateway. That change would leave the actual requirement unresolved.

That result—STP topology is stable, with intentional root and port roles and no recurring MAC-flap or broadcast-storm indications—concerns spanning-tree loop prevention. Uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It can be healthy even while the current LACP bundled links problem remains.

When connected trunk ports disagree about how untagged frames are classified, management and user traffic can land in unintended segments. The indicated result—both ends of the link agree on intended tagged and untagged handling and the untagged test frame enters only the approved VLAN—checks a different mechanism and would not confirm the required LACP bundled links outcome.

This would validate new Central scoped inheritance, not LACP bundled links. New Central includes global, collection, site and device scopes; more specific applicable configuration can override broader inherited values. It is therefore insufficient acceptance evidence for the reported condition.

The alternative targets MAC learning and unintended loops, where rapid MAC moves and broadcast amplification indicate switching topology instability, not a problem fixed by adding a default route. It does not establish the intended roaming reassociation delay behavior described in the scenario.

That action—Check the endpoint's 802.1X supplicant configuration and initial EAPOL exchange—is relevant to 802.1X supplicant disabled. An authentication server cannot authorize an endpoint that never initiates the intended EAP handshake on the controlled link. It does not correct the observed roaming reassociation delay condition.

A silent RADIUS transport failure prevents normal authentication regardless of whether the user certificate or role rules are correct. Validate the AAA server path, UDP service and allowed transport before changing identity policies. would address RADIUS server reachability, but the reported facts instead point to roaming reassociation delay. That change would leave the actual requirement unresolved.

IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. Apply appropriate IPv6 RA protection on untrusted access ports. would address IPv6 router-advertisement spoofing, but the reported facts instead point to EAP-TLS trust-chain failure. That change would leave the actual requirement unresolved.

That action—Trace DHCP relay, VLAN forwarding and server responses after successful WLAN authentication—is relevant to wireless DHCP failure stage. Client association and 802.1X success occur before address allocation; VLAN or relay faults can prevent DHCP without an RF fault. It does not correct the observed EAP-TLS trust-chain failure condition.

The alternative targets AP radio disabled or unsupported channel, where cloud device online status does not prove every radio is active or that target clients can discover the selected channel. It does not establish the intended EAP-TLS trust-chain failure behavior described in the scenario.

This would validate management connectivity and DNS, not DHCP relay on routed segments. Central enrollment requires correctly routed and resolved management traffic; a working user VLAN does not guarantee reachability of the management plane. It is therefore insufficient acceptance evidence for the reported condition.

That result—The LAG status shows intended active members with consistent partner identifiers and forwarding behavior—concerns LACP bundled links. Aggregated links require compatible control and interface parameters; mismatched LACP or VLAN settings can prevent members from joining. It can be healthy even while the current DHCP relay on routed segments problem remains.

When connected trunk ports disagree about how untagged frames are classified, management and user traffic can land in unintended segments. The indicated result—both ends of the link agree on intended tagged and untagged handling and the untagged test frame enters only the approved VLAN—checks a different mechanism and would not confirm the required DHCP relay on routed segments outcome.

Association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. The indicated result—a first-time visitor is presented the expected portal and gains only the approved access after completing it—checks a different mechanism and would not confirm the required gateway role deployment outcome.

This would validate central configuration audit, not gateway role deployment. Management intent, synchronization status and the running device state are distinct; failed changes or local overrides can leave unintended effective configuration. It is therefore insufficient acceptance evidence for the reported condition.

That result—Rendered configurations contain the intended unique addresses and device settings with no unresolved placeholder values—concerns template variable rendering. Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. It can be healthy even while the current gateway role deployment problem remains.

Resilience depends on recovery behavior, routing/bridging convergence and application tolerance, not the number of installed redundant devices. The indicated result—a forced component failure restores approved traffic within a measured recovery-time objective—checks a different mechanism and would not confirm the required baseline before optimization outcome.

This would validate voice queuing under load, not baseline before optimization. QoS can prioritize selected packets when contention occurs but cannot create bandwidth; correct queue treatment reduces latency for critical applications. It is therefore insufficient acceptance evidence for the reported condition.

That result—Post-change tests show better permitted-traffic performance and unchanged denial of prohibited flows—concerns 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 can be healthy even while the current baseline before optimization problem remains.

Access port sum can greatly exceed distribution bandwidth, so congestion and burst tolerance must be planned rather than inferred from port speed labels. Reassess traffic mix and oversubscription ratio against measured peak uplink utilization. would address uplink oversubscription tuning, but the reported facts instead point to storm control tuning. That change would leave the actual requirement unresolved.

That action—Establish QoS trust boundaries and classify traffic according to validated application policy—is relevant to trust and QoS marking boundary. Blindly trusting endpoint markings lets untrusted traffic dominate queues; classification must reflect approved service importance. It does not correct the observed storm control tuning condition.

The alternative targets failure recovery time objective, where resilience depends on recovery behavior, routing/bridging convergence and application tolerance, not the number of installed redundant devices. It does not establish the intended storm control tuning behavior described in the scenario.

That action—Handle API pagination, response codes and provider rate controls in monitoring automation—is relevant to 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 does not correct the observed config drift after manual overrides condition.

Healthy RF and RADIUS reachability cannot compensate for an expired or untrusted certificate that fails the authentication handshake. Monitor and renew EAP-TLS trust-chain certificates before their validity ends. would address certificate expiry monitoring, but the reported facts instead point to config drift after manual overrides. That change would leave the actual requirement unresolved.

The alternative targets access-control change verification, where successful application traffic is only half of policy correctness; overbroad authorization can create exposure while the reported symptom appears resolved. It does not establish the intended config drift after manual overrides behavior described in the scenario.

The alternative targets peak WLAN concurrency, where RF coverage establishes reception, whereas channel contention and client airtime demand govern usable capacity in dense spaces. It does not establish the intended poE budget planning behavior described in the scenario.

Aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. Model oversubscription and dimension distribution uplinks for peak traffic patterns. would address uplink bandwidth capacity, but the reported facts instead point to poE budget planning. That change would leave the actual requirement unresolved.

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 poE budget planning condition.

Fast reliable handoff requires compatible client capabilities, adequate AP overlap and secure authentication continuity rather than just increasing bandwidth. Tune and validate supported roaming and reauthentication behavior for mobile voice clients. would address roaming voice latency, but the reported facts instead point to storm control tuning. That change would leave the actual requirement unresolved.

That action—Reassess traffic mix and oversubscription ratio against measured peak uplink utilization—is relevant to 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 does not correct the observed storm control tuning condition.

The alternative targets LAG capacity and hash distribution, where standard link aggregation typically hashes an individual flow onto one member to avoid reordering; aggregate bandwidth benefits many flows more than one. It does not establish the intended storm control tuning behavior described in the scenario.
