That intervention addresses guest device maximum registration limit, where Guest account and portal settings determine how many devices one guest identity can register, so a permissive limit undermines approved device quotas. Here, the relevant failure is instead: Sponsor group authorization controls the permitted guest account types and durations rather than a portal login alone granting universal sponsorship rights.

That intervention addresses guest account expiration after visit, where Guest identity validity and account lifetime policy control when guest credentials should stop authorizing new sessions; indefinite access contradicts temporary sponsorship. In this question the necessary remedy is “Define separate authorized sponsor groups and guest-type privileges matching daily visitor and extended contractor access requirements”, which this alternative does not provide.

That intervention addresses hotspot acceptable use guest experience, where A hotspot guest portal can enforce an acceptable-use acceptance flow separately from individual credential-based guest login or sponsored account creation. The observed condition is two sponsor teams use the same portal; a facilities receptionist should issue only short daily credentials, while security managers may approve longer contractor accounts; this mechanism addresses another problem.

Authentication requests alone may not supply the session and endpoint context available through appropriately configured RADIUS accounting telemetry. “Validate accounting source, updates, and endpoint IP correlation independently of successful network access authentication” would remedy that alternative situation, but it would not correct the present issue: the DHCP probe needs visibility into DHCP traffic or forwarded metadata to learn client parameters such as vendor class and hostname.

“Inspect privacy and performance implications before expanding application-layer profiling probes into production segments” is the supported response when MAC OUI alone is a broad manufacturer hint; supported HTTP metadata and other probe attributes can improve endpoint identification confidence. Here the decisive response is “Coordinate DHCP relay changes with ISE profiler coverage so new VLANs do not silently lose classification inputs”, so that different intervention does not meet the stated requirement.

SNMP traps can provide timely device-change signals to a profiler but require correct destinations, event types, and ISE trap processing. “Audit trap delivery and source security when switches or ISE policy nodes are replaced” applies to that other condition. The reported evidence is a campus wants Cisco ISE to distinguish common printers and laptops through DHCP client metadata but profiling has only their MAC addresses; this alternative would address the wrong dependency.

Authentication records identify login attempts, whereas TACACS+ command accounting needs separate device configuration to report executed administrative actions. “Confirm command accounting and log retention on each device platform after configuration templates are updated” would remedy that alternative situation, but it would not correct the present issue: administrative AAA needs a tightly controlled fallback access design for total external server unavailability without broadly bypassing central policy in normal operation.

“Test role and network device combinations as a matrix whenever new groups or NADs are introduced” is the supported response when device administration policy-set selection and authorization conditions must scope identities and network device groups so unrelated equipment does not inherit privileges. Here the decisive response is “Guard emergency credentials and periodically simulate AAA unavailability so a failed remote service does not strand network operations”, so that different intervention does not meet the stated requirement.

TACACS+ requests must come from a recognized NAD with compatible shared secret, source identity and device administration service configuration. “Coordinate secret rotations between network-device templates and ISE records with immediate test access and rollback plans” applies to that other condition. The reported evidence is a switch is managed through TACACS+ only, and its administrators are locked out during an authorized maintenance outage that makes both ISE servers unreachable; this alternative would address the wrong dependency.

The phone authenticates to its intended voice domain and the workstation independently receives the permitted data authorization. This is a different failure mechanism from the current case, which concerns live Logs show authentication success and a final authorization profile granting the correct employee access instead of the contractor result.

This option instead describes a registered device matches its intended limited access and an unknown or spoofed address fails to obtain unrestricted user network access. Testing that independent mechanism would not show whether the reported fault has been resolved.

The registered printer obtains its specific print VLAN or ACL while an unknown MAC on the same port does not inherit that access. The stem describes a user authenticates successfully to AD using a wired 802.1X connection, but the workstation receives a restrictive VLAN because its authorization profile matches a contractor rule, so this explanation does not account for the observations.

Certificate-based BYOD requires an appropriate issuing CA and working certificate provisioning chain; a portal alone cannot create trusted device credentials. “Monitor issuing CA health, certificate validity, and renewal capacity before enabling large-scale device onboarding” would remedy that alternative situation, but it would not correct the present issue: the supported native supplicant provisioning workflow installs the approved wireless settings and device credential; portal registration alone does not configure EAP-TLS.

“Revalidate certificate identity mapping and BYOD registration conditions when importing CA chains or modifying authentication profiles” is the supported response when certificate chain trust establishes authenticity but does not substitute for the registered BYOD attributes and identity conditions required by the access policy. Here the decisive response is “Pilot supplicant provisioning across client operating system releases and maintain support instructions for installation restrictions”, so that different intervention does not meet the stated requirement.

Single-SSID onboarding requires a distinct initial authorization state and registration flow before an enrolled device can receive its final trusted access result. “Test both first-time and returning-device sessions and verify that an unknown device cannot skip the onboarding conditions” applies to that other condition. The reported evidence is windows laptops redirect to the BYOD portal but users install no supplicant settings and attempt password authentication on the secure SSID afterward; this alternative would address the wrong dependency.

TrustSec classification is useful only when tags or equivalent classification context are preserved across the supported path to enforcement. “Verify supported inline tagging or SGT exchange mechanisms and configure the downstream device to receive accurate group context” would remedy that alternative situation, but it would not correct the present issue: identity source sequences control where ISE looks up a principal and how defined source selection and not-found behavior are handled.

“Create and assign a narrowly scoped ISE downloadable ACL in the contractor authorization result and verify the device applies it” is the supported response when a downloadable ACL can provide session-specific access restrictions through supported RADIUS authorization to a capable network device. Here the decisive response is “Configure the approved identity source sequence to evaluate the appropriate AD and internal identity sources for the correct access policy”, so that different intervention does not meet the stated requirement.

Cisco TrustSec security group tags and group-based policy can carry identity classification independent of transient endpoint IP address. “Assign the intended SGT in ISE authorization and configure supported NAD propagation and enforcement with approved group-based policies” applies to that other condition. The reported evidence is an ISE policy authenticates internal employees and a separate internal guest population, but an identity source sequence checks only the guest database for corporate usernames; this alternative would address the wrong dependency.

A controlled primary outage is recovered with one active write-capable administration node and consistent policy replication to service nodes. This is a different failure mechanism from the current case, which concerns a test guest completes the portal flow through the intended PSN path and receives authorized access without an unexpected repeated redirect.

This option instead describes a simulated policy service outage leaves other supported access paths operational and administration and monitoring remain accessible through their intended nodes. Testing that independent mechanism would not show whether the reported fault has been resolved.

Supplicants validate the presented EAP server name and trust chain, and a known user authenticates through the replacement PSN. The stem describes a guest authentication deployment uses multiple PSNs, but after an access change a device is redirected back to a different session node and repeatedly sees an onboarding portal, so this explanation does not account for the observations.

The guest receives a notification with only the approved account details, and delivery logs no longer report authentication failure. This is a different failure mechanism from the current case, which concerns the authorized receptionist creates a time-limited guest account while a user without sponsorship privileges cannot create new visitor access.

This option instead describes a self-registered test guest remains unauthenticated for production access until a designated sponsor approves the request. Testing that independent mechanism would not show whether the reported fault has been resolved.

Guest browsers open the designated HTTPS portal without certificate-name or issuer warnings while a fake hostname still fails validation. The stem describes a lobby visitor needs temporary Wi-Fi access, but the receptionist cannot issue an account even though the sponsor web page opens successfully, so this explanation does not account for the observations.

Device administration policy-set selection and authorization conditions must scope identities and network device groups so unrelated equipment does not inherit privileges. “Build correctly ordered TACACS device administration policy sets using approved NAD groups and administrator identity roles” would remedy that alternative situation, but it would not correct the present issue: successful TACACS+ authentication does not prove command authorization: shell profile, command set, identity group, and matched device policy may independently restrict commands.

“Verify and enable the supported device administration licensing and persona service before constructing TACACS+ policy rules” is the supported response when ISE TACACS+ device administration requires the relevant enabled licensing entitlement and service activation, beyond ordinary RADIUS NAC capabilities. Here the decisive response is “Inspect the ISE device administration Live Logs and command authorization details, then correct the specific command set or role conditions if approved”, so that different intervention does not meet the stated requirement.

Administrative AAA needs a tightly controlled fallback access design for total external server unavailability without broadly bypassing central policy in normal operation. “Configure a protected local break-glass account or method list fallback that applies only under the approved AAA server failure condition” applies to that other condition. The reported evidence is an authorized switch engineer can log in over TACACS+ and run show commands but receives authorization failures for an approved interface configuration command; this alternative would address the wrong dependency.

The same test scanner matches the specific restricted profile while an ordinary Android handset remains in the generic device class. This is a different failure mechanism from the current case, which concerns the replacement receives its restricted scanner authorization and a device using the old retired identifier does not pass the previous allow rule.

This option instead describes an approved phone generates expected LLDP or CDP derived attributes in the endpoint record and matches the correct phone profile. Testing that independent mechanism would not show whether the reported fault has been resolved.

A representative device is still accurately classified while profiler processing backlog remains within its healthy operating range. The stem describes a scanner is replaced by new hardware but ISE retains the previous scanner MAC in an allowed group, enabling an unknown device with that old address to receive scanner permissions, so this explanation does not account for the observations.

Identity source sequences control where ISE looks up a principal and how defined source selection and not-found behavior are handled. “Test duplicate usernames and identity-store selection after adding or changing local and external identity providers” would remedy that alternative situation, but it would not correct the present issue: an authorization change in ISE does not necessarily alter an already established NAD session until reauthentication or Change of Authorization takes effect.

“Rotate RADIUS secrets using a coordinated change procedure and validate authentication on both primary and backup policy servers” is the supported response when RADIUS client message validation depends on compatible shared secrets and endpoint identity settings at both ISE and the network device. Here the decisive response is “Validate RADIUS CoA reachability and session identification during registration and posture design reviews”, so that different intervention does not meet the stated requirement.

A broad policy set selection condition can group unrelated WLANs, causing later authentication and authorization rules to use the wrong service assumptions. “Test multiple SSIDs from each controller against explicit policy-set conditions after wireless migrations” applies to that other condition. The reported evidence is a newly enrolled employee must leave a temporary registration VLAN and receive normal corporate access, but the switch keeps using the original session authorization; this alternative would address the wrong dependency.
