Cisco 300-715 Bundle

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: TACACS+ requests must come from a recognized NAD with compatible shared secret, source identity and device administration service configuration.

“Inspect the ISE device administration Live Logs and command authorization details, then correct the specific command set or role conditions if approved” is the supported response when successful TACACS+ authentication does not prove command authorization: shell profile, command set, identity group, and matched device policy may independently restrict commands. Here the decisive response is “Correct the router's source address and TACACS+ shared secret to match the authorized ISE network device definition and retest login”, so that different intervention does not meet the stated requirement.

ISE TACACS+ device administration requires the relevant enabled licensing entitlement and service activation, beyond ordinary RADIUS NAC capabilities. “Verify and enable the supported device administration licensing and persona service before constructing TACACS+ policy rules” applies to that other condition. The reported evidence is a replacement router sends TACACS+ requests to a reachable ISE service but every login fails after a network-device template copied the wrong shared secret; this alternative would address the wrong dependency.

Test members land in the appropriate VLAN with expected DHCP addressing and cannot reach resources outside their group policy. This is a different failure mechanism from the current case, which concerns an approved test PEAP client matches its intended rule and a managed certificate client still follows the stronger certificate policy.

This option instead describes a certificate carrying the expected account identifier resolves to that principal and receives only the approved network authorization. Testing that independent mechanism would not show whether the reported fault has been resolved.

A known managed certificate succeeds while a certificate from an untrusted issuer is still rejected with a clear authentication failure reason. The stem describes legacy managed endpoints use PEAP with an inner password method, but they fail after a policy was changed to allow only certificate-based EAP methods, so this explanation does not account for the observations.

TrustSec classification is useful only when tags or equivalent classification context are preserved across the supported path to enforcement. “Test tag propagation across every changed trunk or device boundary and document supported transport or mapping choices” would remedy that alternative situation, but it would not correct the present issue: MAC addresses are not cryptographic identities, and a permissive default MAB result defeats endpoint inventory controls and enables trivial impersonation.

“Use positive and negative request fixtures to detect shadowed or overbroad policy conditions after every major edit” is the supported response when policy evaluation uses rule order and the first matching conditions at the applicable stage, so a broad earlier rule can shadow a later specific result. Here the decisive response is “Track unknown endpoints in Live Logs and review MAB permissions and device identity group membership regularly”, so that different intervention does not meet the stated requirement.

Wired host modes determine how multiple MAC or voice and data sessions are authenticated on one switchport and must match the connected endpoint topology. “Test phone plus PC boot and reauthentication order before applying host-mode changes to shared access ports” applies to that other condition. The reported evidence is an operations team adds a blanket MAB authorization rule that permits all unknown endpoint MAC addresses onto the corporate user VLAN; this alternative would address the wrong dependency.

Client certificate validity includes its revocation status when policy requires that check; a valid signature and unexpired date alone do not establish current authorization. “Monitor revocation responder availability and document controlled outage behavior instead of disabling checks to hide errors” would remedy that alternative situation, but it would not correct the present issue: android MAC randomization can change the address seen by ISE and break BYOD rules that bind registration to a fixed MAC or MAC-in-certificate value.

“Maintain a per-platform test matrix and retest client onboarding after mobile operating system upgrades” is the supported response when the native supplicant configuration mechanism varies by operating system, so one platform's provisioning wizard or user interaction is not universal. Here the decisive response is “Test modern Android enrollment and private-address behavior separately from older mobile platforms before using MAC-specific conditions”, so that different intervention does not meet the stated requirement.

A registered BYOD device can retain network credentials until its registration status and certificates are revoked or invalidated through the intended lifecycle process. “Train users to report loss promptly and test device-specific revocation independently of account password changes” applies to that other condition. The reported evidence is modern Android phones complete enrollment but the authorized registration rule fails after connection profile creation changes their reported Wi-Fi MAC address; this alternative would address the wrong dependency.

That intervention addresses profiler probe event storm capacity, where Excessive unfiltered profiling telemetry can overload processing queues without improving endpoint identification accuracy. Here, the relevant failure is instead: Supported network device sensors can deliver endpoint metadata to ISE that may strengthen classification beyond a broad vendor address prefix.

That intervention addresses wireless controller profiling data feed, where Wireless profiling depends on the controller and ISE exchanging suitable session and device attributes, which may differ from wired NAD telemetry. In this question the necessary remedy is “Enable the relevant switch device-sensor collection and RADIUS attribute forwarding to an ISE profiler with appropriate policies”, which this alternative does not provide.

That intervention addresses stale endpoint mac identity after replacement, where Endpoint identity records persist across hardware replacement unless cleaned up; MAB classification and permission can be reused by a device claiming the retired MAC. The observed condition is cisco ISE identifies conference-room phones only by MAC OUI, even though access switches can report richer device sensor attributes such as LLDP and CDP information; this mechanism addresses another problem.

Successful portal login authenticates the visitor but does not inherently restrict the final authorization profile to public Internet destinations. “Verify isolation from both wired and wireless guest access paths using positive Internet and negative internal reachability tests” would remedy that alternative situation, but it would not correct the present issue: portal authentication uses the identity source or source sequence selected for that portal, which can be separate from corporate employee authentication policies.

“Recheck WLC software compatibility and supported authorization attributes when duplicating a guest portal design between controller families” is the supported response when ISE must return a network device-compatible RADIUS result, and the controller must map that result into the correct guest authorization behavior. Here the decisive response is “Test guest and employee identity overlaps after portal edits or identity source sequence changes”, so that different intervention does not meet the stated requirement.

An existing guest network session needs a supported authorization refresh such as RADIUS CoA for its final access result to replace the redirection permissions. “Test both portal success and NAD post-login policy in guest acceptance checks, not merely the browser success page” applies to that other condition. The reported evidence is the visitor portal exists and accepts a username, but its authentication identity source points to enterprise AD instead of the internal guest users created by sponsors; this alternative would address the wrong dependency.

A compliant test laptop passes while a test laptop with missing or disabled required protection becomes noncompliant and receives remediation access. This is a different failure mechanism from the current case, which concerns a test unencrypted laptop is classified noncompliant while an otherwise comparable encrypted laptop passes the requirement.

This option instead describes a test endpoint reports actual checks and a compliance state in ISE rather than remaining unassessed after successful identity authentication. Testing that independent mechanism would not show whether the reported fault has been resolved.

A noncompliant test endpoint retrieves the approved update but cannot reach restricted data until it reports compliant posture. The stem describes a regulated laptop must use full-disk encryption, but it passes posture even when the protected volume is not encrypted because no matching requirement was enabled, so this explanation does not account for the observations.

The ISE allowed protocol profile controls which EAP methods are permitted for a selected authentication rule independently of the client's own capabilities. “Review protocol-set assignments and positive and negative EAP method tests whenever copying wireless policy sets” would remedy that alternative situation, but it would not correct the present issue: closed mode prevents ordinary data-plane access until a supported authentication or fallback policy grants authorization; a missing supplicant has no successful 802.1X exchange.

“Review failed authentication populations, voice devices, and access-switch support before transitioning from monitor to enforcement mode” is the supported response when monitor mode gathers identity and authentication evidence while minimizing enforcement impact, whereas closed mode can deny unauthenticated traffic immediately. Here the decisive response is “Inventory unsupported endpoints and test fallback order, critical access, and failure behavior before enabling closed mode across production ports”, so that different intervention does not meet the stated requirement.

Cisco ISE identifies incoming RADIUS clients by their source IP and configured network device definition, not by SSID name alone. “Audit WLAN controller RADIUS source addresses and secrets during HA, NAT, or controller replacement changes” applies to that other condition. The reported evidence is a plant access switch enforces 802.1X in closed mode, and unmanaged legacy devices have no supplicant, so they cannot reach the approved authentication process; this alternative would address the wrong dependency.

Successful Sponsor Portal sign-in does not imply the account has privileges to create the requested guest type or use the intended portal scope. “Assign the receptionist an approved sponsor group with the specific guest account creation permissions and time limits needed for the lobby workflow” would remedy that alternative situation, but it would not correct the present issue: guest identity validity and account lifetime policy control when guest credentials should stop authorizing new sessions; indefinite access contradicts temporary sponsorship.

“Configure a supported hotspot guest portal and redirect policy that requires the published terms acceptance before granting visitor Internet authorization” is the supported response when a hotspot guest portal can enforce an acceptable-use acceptance flow separately from individual credential-based guest login or sponsored account creation. Here the decisive response is “Use a guest type with the approved validity window, expire the account, and ensure active-session handling respects the access policy”, so that different intervention does not meet the stated requirement.

Sponsor group authorization controls the permitted guest account types and durations rather than a portal login alone granting universal sponsorship rights. “Define separate authorized sponsor groups and guest-type privileges matching daily visitor and extended contractor access requirements” applies to that other condition. The reported evidence is a contractor was issued a two-day visitor credential but can still reconnect to the guest WLAN several weeks later after its visit ended; this alternative would address the wrong dependency.

Successful Sponsor Portal sign-in does not imply the account has privileges to create the requested guest type or use the intended portal scope. “Assign the receptionist an approved sponsor group with the specific guest account creation permissions and time limits needed for the lobby workflow” would remedy that alternative situation, but it would not correct the present issue: browsers validate the portal server certificate trust chain and subject alternative names independently of the RADIUS authentication decision.

“Allow only the needed DNS, DHCP, portal, and support service destinations in the redirect or preauthentication access path” is the supported response when the redirect ACL must permit the specific network prerequisites for the portal while restricting ordinary data-plane access until a user is authenticated. Here the decisive response is “Bind a trusted portal certificate with an appropriate SAN and ensure guest clients can validate its issuing CA through the chosen DNS name”, so that different intervention does not meet the stated requirement.

Centralized Web Authentication needs the NAD to receive and enforce an ISE authorization result that includes a supported portal redirection mechanism. “Create an appropriate CWA authorization profile with portal URL and redirection ACL and ensure the controller is configured for the intended web-auth flow” applies to that other condition. The reported evidence is visitors are redirected to the correct guest portal yet their browsers display an untrusted certificate warning because the portal certificate does not cover the advertised hostname; this alternative would address the wrong dependency.

That intervention addresses tacacs plus aaa for network device administrators, where RADIUS network access authorization and TACACS+ device administration offer different policy and command-control capabilities in ISE. Here, the relevant failure is instead: Command authorization must have an effective explicit deny or allowlist design that is evaluated as configured; a broad permit can undermine restrictions.

That intervention addresses tacacs command accounting audit trail, where Authentication records identify login attempts, whereas TACACS+ command accounting needs separate device configuration to report executed administrative actions. In this question the necessary remedy is “Refine the applicable TACACS command set to deny the unwanted command and test the matched arguments without granting broad bypass”, which this alternative does not provide.

That intervention addresses tacacs shell profile privilege level, where An ISE TACACS shell profile can return session privilege attributes, which must match the operator's role and device requirements. The observed condition is an administrator tries to block a high-risk erase command while using a permissive default command set, but the dangerous command still succeeds; this mechanism addresses another problem.
