Wide channels can improve peak rates per connection yet shrink available channel separation, raising cochannel contention in dense networks. The indicated result—peak-load tests show better aggregate throughput and fewer collisions with the selected width—checks a different mechanism and would not confirm the required interference spectrum diagnosis outcome.

That result—The report contrasts like-for-like baseline and post-change throughput, latency, retries and error statistics—concerns baseline before optimization. Optimization claims require equivalent loads, test methods and service metrics before and after; otherwise changes in demand confound comparison. It can be healthy even while the current interference spectrum diagnosis problem remains.

This would validate legacy low-rate airtime overhead, not interference spectrum diagnosis. Low PHY data rates use more airtime per transmitted bit; rate changes must be constrained by coverage and device support. It is therefore insufficient acceptance evidence for the reported condition.

That result—The AAA collector receives accurate start/stop accounting records for the authorized client session—concerns RADIUS accounting versus authorization. Authentication and authorization can work while accounting packets are missing; reliable session tracking needs the additional accounting path. It can be healthy even while the current firmware-induced configuration drift problem remains.

This would validate RADIUS server reachability, not firmware-induced configuration drift. A silent RADIUS transport failure prevents normal authentication regardless of whether the user certificate or role rules are correct. It is therefore insufficient acceptance evidence for the reported condition.

An ACL can block selected Layer 4 flows while other connectivity remains healthy; removing all controls is an unsafe shortcut. The indicated result—policy logs or counters identify the matching rule and the repaired rule permits only the approved service—checks a different mechanism and would not confirm the required firmware-induced configuration drift outcome.

The alternative targets route redistribution filters, where unfiltered redistribution can expose unintended paths, create loops and carry unnecessary routes between otherwise isolated segments. It does not establish the intended management connectivity and DNS behavior described in the scenario.

That action—Distinguish Central's site/location assignment from the group-based configuration scope in Classic Central—is relevant to classic Central site versus group. Classic Central uses groups to distribute shared configuration while sites provide physical-location organization, so modifying location alone need not change running intent. It does not correct the observed management connectivity and DNS condition.

Management intent, synchronization status and the running device state are distinct; failed changes or local overrides can leave unintended effective configuration. Inspect configuration audit and effective device state rather than assuming an issued change was applied. would address central configuration audit, but the reported facts instead point to management connectivity and DNS. That change would leave the actual requirement unresolved.

A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. The indicated result—the low-level topology labels uplink capacity, device roles, VLAN boundaries and redundant forwarding paths—checks a different mechanism and would not confirm the required OSPF area design outcome.

That result—The projected and tested peak traffic remains within the chosen uplink design's acceptable utilization and loss bounds—concerns uplink bandwidth capacity. Aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. It can be healthy even while the current OSPF area design problem remains.

This would validate inventory and dependency discovery, not OSPF area design. Missing uplink, power, VLAN, routing and identity dependencies cause apparently successful device replacements to disconnect applications or clients unexpectedly. It is therefore insufficient acceptance evidence for the reported condition.

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.

This would validate REST API authentication boundaries, not alert correlation and noise reduction. API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. It is therefore insufficient acceptance evidence for the reported condition.

That result—The monitoring platform receives correct operational interface states and counters under its approved access rights—concerns SNMP monitoring scope. Monitoring requires authorized protocol access and device-supported counters; the existence of a monitoring server alone produces no reliable telemetry. It can be healthy even while the current alert correlation and noise reduction problem remains.

This would validate VSF versus VSX platform planning, not access/distribution hierarchy. 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 is therefore insufficient acceptance evidence for the reported condition.

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 access/distribution hierarchy problem remains.

VLANs divide Layer 2 domains, whereas VRFs maintain separate Layer 3 routing contexts; any intentional crossing needs controlled connectivity. The indicated result—the route inventory shows distinct VRF tables and only documented cross-VRF communication paths—checks a different mechanism and would not confirm the required access/distribution hierarchy outcome.

A guest can associate and receive a lease without completing the portal flow; redirect and pre-auth policy must permit necessary portal dependencies. Check captive-portal redirect path, DNS and allowed pre-authentication services. would address captive portal redirect fault, but the reported facts instead point to MAC learning and unintended loops. 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 MAC learning and unintended loops condition.

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 MAC learning and unintended loops behavior described in the scenario.

Authentication and authorization can work while accounting packets are missing; reliable session tracking needs the additional accounting path. The indicated result—the AAA collector receives accurate start/stop accounting records for the authorized client session—checks a different mechanism and would not confirm the required wrong Central scope override 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 wrong Central scope override problem remains.

This would validate captive portal redirect fault, not wrong Central scope override. A guest can associate and receive a lease without completing the portal flow; redirect and pre-auth policy must permit necessary portal dependencies. It is therefore insufficient acceptance evidence for the reported condition.

This would validate firmware compatibility dependency, not config drift after manual overrides. Release-specific feature and compatibility constraints can break management or forwarding despite a successful image installation. It is therefore insufficient acceptance evidence for the reported condition.

That result—A pilot validates critical services and the production plan provides checkpoints, maintenance windows and restoration conditions—concerns firmware rollout staging. Software changes can alter forwarding, management or authentication behavior, so a limited pilot provides evidence before broad deployment. It can be healthy even while the current config drift after manual overrides problem remains.

Network device health does not establish application experience; end-to-end synthetic tests expose DNS, transport and service delays along the client path. The indicated result—sensor results report reachability and response timing for the designated application from the relevant location—checks a different mechanism and would not confirm the required config drift after manual overrides outcome.

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 network asset lifecycle. That change would leave the actual requirement unresolved.

That action—Update topology, ownership and change documentation alongside effective network changes—is relevant to topology and documentation currency. Operational documents are useful only when they reflect the running state and its change history; stale diagrams waste troubleshooting effort. It does not correct the observed network asset lifecycle condition.

The alternative targets NTP clock alignment, where accurate time supports certificate validation, event correlation and change records; unsynchronized clocks obscure cause and effect. It does not establish the intended network asset lifecycle behavior described in the scenario.

That action—Inspect token scopes and endpoint authorization when the API returns a forbidden response—is relevant to central API unauthorized response. A valid login or token does not imply access to every management resource; 403 generally indicates denied permissions rather than a switch port failure. It does not correct the observed incorrect RADIUS role result condition.

The alternative targets wireless DHCP failure stage, where client association and 802.1X success occur before address allocation; VLAN or relay faults can prevent DHCP without an RF fault. It does not establish the intended incorrect RADIUS role result behavior described in the scenario.

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 incorrect RADIUS role result. That change would leave the actual requirement unresolved.
