The alternative targets MAC authentication fallback fault, where endpoints without a supported supplicant need a deliberate alternative classification mechanism, not general unrestricted VLAN access. It does not establish the intended unauthorized DHCP server behavior described in the scenario.

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 unauthorized DHCP server. That change would leave the actual requirement unresolved.

That action—Trace VLAN membership across each intervening trunk and restore the missing permitted VLAN—is relevant to missing trunk VLAN. A frame cannot traverse a trunk on which its tagged VLAN is not allowed; local endpoint configuration can be fully correct. It does not correct the observed unauthorized DHCP server condition.

EAP-TLS verifies certificate-based identities through the configured authentication system; a shared PSK does not give per-device certificate identity. The indicated result—a representative approved device completes certificate-based enterprise authentication and receives its authorized network role—checks a different mechanism and would not confirm the required dynamic role enforcement outcome.

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 dynamic role enforcement problem remains.

This would validate MAC authentication for headless devices, not dynamic role enforcement. MAC authentication can support devices without a supplicant but is weaker than cryptographic identity, so narrow policy and inventory are essential. It is therefore insufficient acceptance evidence for the reported condition.

This would validate port mirroring for packet capture, not alert correlation and noise reduction. A capture tool sees only frames delivered to it; a correctly scoped mirror copies relevant ingress or egress traffic without changing production forwarding. It is therefore insufficient acceptance evidence for the reported condition.

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 alert correlation and noise reduction problem remains.

Centralized time-stamped records preserve context for multi-device analysis and avoid relying on volatile local event buffers. The indicated result—the collector receives attributable device events with usable timestamps and appropriate retention settings—checks a different mechanism and would not confirm the required alert correlation and noise reduction outcome.

That action—Inspect matching route prefixes and prefer the longest matching prefix in path analysis—is relevant to longest-prefix route selection. IP forwarding selects the most specific matching destination prefix before comparing less-specific alternatives; a summary route does not override a more-specific match. It does not correct the observed route missing in correct VRF condition.

The alternative targets ACL deny versus service outage, where an ACL can block selected Layer 4 flows while other connectivity remains healthy; removing all controls is an unsafe shortcut. It does not establish the intended route missing in correct VRF behavior described in the scenario.

Traffic bound for other subnets needs a reachable Layer 3 next hop; a functioning local broadcast domain does not provide routing. Verify the endpoint's default gateway and local first-hop reachability. would address missing default gateway, but the reported facts instead point to route missing in correct VRF. That change would leave the actual requirement unresolved.

An AP online indicator does not prove successful client onboarding; stage-specific events narrow diagnosis to radio, identity, addressing or portal dependencies. Review per-client connection health and failure-stage telemetry in Aruba Central. would address central client health visibility, but the reported facts instead point to SNMP monitoring scope. That change would leave the actual requirement unresolved.

That action—Capture a restorable configuration checkpoint and change record before modifying network intent—is relevant to configuration backup before changes. Reversible change management requires knowing the previous effective state, not merely retaining a screenshot of intended edits. It does not correct the observed SNMP monitoring scope condition.

The alternative targets alert correlation and noise reduction, where dependency-aware grouping prevents alert floods from hiding the primary failure and makes operational response more focused. It does not establish the intended SNMP monitoring scope behavior described in the scenario.

That result—A representative approved device completes certificate-based enterprise authentication and receives its authorized network role—concerns corporate EAP-TLS SSID. EAP-TLS verifies certificate-based identities through the configured authentication system; a shared PSK does not give per-device certificate identity. It can be healthy even while the current new Central scoped inheritance problem remains.

Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. The indicated result—rendered configurations contain the intended unique addresses and device settings with no unresolved placeholder values—checks a different mechanism and would not confirm the required new Central scoped inheritance outcome.

This would validate gateway role deployment, not new Central scoped inheritance. Gateway responsibilities such as tunnel termination and role enforcement depend on the chosen software architecture and supported role. It is therefore insufficient acceptance evidence for the reported condition.

That action—Verify the AP's negotiated Ethernet link and available PoE power meet its installed feature requirements—is relevant to AP uplink power and negotiation. Wireless features depend on the wired uplink and power available to the AP; sufficient coverage does not prove the device is operating at full capacity. It does not correct the observed dynamic role enforcement condition.

The alternative targets VRF route-context configuration, where routes and interfaces are looked up within the relevant VRF; a default route in a different table cannot repair a missing path. It does not establish the intended dynamic role enforcement behavior described in the scenario.

Association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. Implement the authorized guest captive-portal workflow and associated access policy. would address guest captive-portal flow, but the reported facts instead point to dynamic role enforcement. That change would leave the actual requirement unresolved.

This would validate dual-homed downstream aggregation, not failure-domain isolation. Hardware redundancy is ineffective if every downstream path still depends on one forwarding node or unsound Layer 2 topology. It is therefore insufficient acceptance evidence for the reported condition.

Separate segments help control broadcast reachability and policy scope; a VLAN label alone is not an authorization policy. The indicated result—the logical design maps each user or device class to its VLAN or routed segment and approved inter-segment access—checks a different mechanism and would not confirm the required failure-domain isolation outcome.

That result—The implementation schedule contains bounded change groups, checkpoint tests and explicit reversal criteria before wider rollout—concerns change-risk classification. Changing many dependent control planes at once obscures root causes and enlarges outage blast radius; staging supplies evidence and rollback points. It can be healthy even while the current failure-domain isolation problem remains.

This would validate RF survey and building materials, not address pool capacity. Propagation and attenuation vary with walls, shelving and device environments; a diagram alone cannot establish coverage or service quality. It is therefore insufficient acceptance evidence for the reported condition.

The low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. The indicated result—the signed acceptance matrix associates each campus requirement with a measurable test, expected result and responsible owner—checks a different mechanism and would not confirm the required address pool capacity outcome.

That result—The identity design includes certificate enrollment, renewal, revocation and a successful mutual-trust authentication test—concerns EAP-TLS certificate lifecycle. EAP-TLS authenticates with certificates, so healthy network transport alone cannot correct absent trust, expired credentials or unmanaged key lifecycle. It can be healthy even while the current address pool capacity problem remains.

That action—Choose antenna pattern and placement for the coverage geometry and client distribution—is relevant to directional antenna selection. Directional gain shapes energy into target areas and can reduce unwanted spill, but a poorly aimed directional antenna creates coverage holes elsewhere. It does not correct the observed coverage versus capacity tradeoff condition.

Two logical paths do not provide independent availability when they share a single cable route, power supply or upstream component. Identify shared failure domains and separate critical links, power and devices where feasible. would address failure-domain isolation, but the reported facts instead point to coverage versus capacity tradeoff. That change would leave the actual requirement unresolved.

The alternative targets 6 GHz WLAN compatibility, where 6 GHz operation requires capable client hardware and supported regulatory and security settings; enabling the band does not upgrade legacy adapters. It does not establish the intended coverage versus capacity tradeoff behavior described in the scenario.

Hardware redundancy is ineffective if every downstream path still depends on one forwarding node or unsound Layer 2 topology. The indicated result—a link or peer failure test keeps supported endpoint traffic forwarded over the surviving upstream path—checks a different mechanism and would not confirm the required failure-domain isolation outcome.

This would validate acceptance of WLAN security and mobility, not failure-domain isolation. 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—The selected hardware and architecture documentation match the intended stacking or peer-control behavior and supported model family—concerns VSF versus VSX platform planning. VSF forms a virtual switch with supported stacking members; VSX coordinates two peers while retaining separate control planes, so support and failure domains differ. It can be healthy even while the current failure-domain isolation problem remains.
