Question 120

An ISE administrator troubleshoots the following: A network-access policy is configured to ignore directory outage and silently authenticate all unknown usernames using a catch-all local account. Which technical behavior is MOST relevant to this design?

  1. The ISE internal identity store can validate accounts without relying on an external AD or LDAP directory for the intended test.
  2. Identity-store ordering and duplicate account representations can change or block authentication when a username exists in multiple databases.
  3. Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.
  4. Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

Explanation

Correct Answer

C:

Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity. This behavior directly governs the stated requirement. The recommended action is: Replace the catch-all fallback with an explicit supported identity-store and failure policy that denies unauthorized identities. The acceptance result is: An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.

Incorrect Answers

A:

Track EAP certificate chain, identity mapping, and renewal as distinct controls. The repeat risk here is different: Document and test certificate naming conventions during enrollment-template changes. A directly relevant preventive control is: Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.

B:

Alert on ISE node time drift and authoritative NTP reachability. The repeat risk here is different: Document and test certificate naming conventions during enrollment-template changes. A directly relevant preventive control is: Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.

D:

Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The repeat risk here is different: Document and test certificate naming conventions during enrollment-template changes. A directly relevant preventive control is: Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.

Question 121

An access-security change request states: A network-access policy is configured to ignore directory outage and silently authenticate all unknown usernames using a catch-all local account. Which readback demonstrates that the actual problem was solved?

  1. A pilot identity is resolved by the intended external or internal source with a traceable authentication result.
  2. An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.
  3. The known `uid` resolves to its proper directory entry while an unknown account does not authenticate.
  4. A managed workstation authenticates via 802.1X while the pre-registered badge reader uses MAB and receives restricted authorization.

Explanation

Correct Answer

B:

An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded. The required remediation is: Replace the catch-all fallback with an explicit supported identity-store and failure policy that denies unauthorized identities. It works because identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.

Incorrect Answers

A:

Audit overlapping account namespaces before modifying identity-source sequences. The actual fault is governed by a different mechanism: Test negative authentication cases during directory-failover policy reviews. The needed response is: An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.

C:

Maintain per-directory schema mapping tests before identity store migrations. The actual fault is governed by a different mechanism: Test negative authentication cases during directory-failover policy reviews. The needed response is: An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.

D:

Add an explicitly authorized MAB method and appropriate event-driven policy handling for devices that cannot perform 802.1X. The actual fault is governed by a different mechanism: Test negative authentication cases during directory-failover policy reviews. The needed response is: An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.

Question 122

During a Cisco ISE postchange review, the following is observed: A network-access policy is configured to ignore directory outage and silently authenticate all unknown usernames using a catch-all local account. What validation should be repeated before subsequent rollouts?

  1. Test external MFA service failures and document secure fail-closed or permitted exception behavior.
  2. Expire temporary local users and prevent test identity stores from matching production requests.
  3. Test negative authentication cases during directory-failover policy reviews.
  4. Include DNS locator and domain connectivity checks in ISE node renumbering.

Explanation

Correct Answer

C:

Test negative authentication cases during directory-failover policy reviews. This control addresses recurrence of the observed failure. The governing behavior is: Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity. The ongoing acceptance check remains: An unknown test principal is denied even when the primary identity source is unavailable, while approved continuity behavior is recorded.

Incorrect Answers

A:

Test negative authentication cases during directory-failover policy reviews. The offered choice instead concerns a different principle: Test external MFA service failures and document secure fail-closed or permitted exception behavior. Those technical conditions are not interchangeable.

B:

Test negative authentication cases during directory-failover policy reviews. The offered choice instead concerns a different principle: Expire temporary local users and prevent test identity stores from matching production requests. Those technical conditions are not interchangeable.

D:

Test negative authentication cases during directory-failover policy reviews. The offered choice instead concerns a different principle: Include DNS locator and domain connectivity checks in ISE node renumbering. Those technical conditions are not interchangeable.

Question 123

In a staged Cisco ISE network access rollout, the team observes: Employees connect to an 802.1X wireless SSID, but the WLC sends RADIUS requests using a source IP not registered as a network device in ISE. What should the team change before declaring this work complete?

  1. Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules.
  2. Inspect the matched wireless policy set and authorization condition, then return the appropriate supported VLAN or role attributes to the WLC.
  3. Return the supported VLAN or role authorization attributes through an appropriate ISE profile selected for contractors.
  4. Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols.

Explanation

Correct Answer

D:

Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols. This is appropriate because iSE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy. It should be verified by this evidence: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

Incorrect Answers

A:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. In the case being tested, Test negative authentication cases during directory-failover policy reviews. The necessary acceptance evidence is: Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols.

B:

Audit EAP method availability and certificate trust before deploying new WLANs. In the case being tested, Test negative authentication cases during directory-failover policy reviews. The necessary acceptance evidence is: Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols.

C:

Return the supported VLAN or role authorization attributes through an appropriate ISE profile selected for contractors. In the case being tested, Test negative authentication cases during directory-failover policy reviews. The necessary acceptance evidence is: Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols.

Question 124

An identity and device-administration engineer evaluates: Employees connect to an 802.1X wireless SSID, but the WLC sends RADIUS requests using a source IP not registered as a network device in ISE. What underlying Cisco ISE dependency explains this result?

  1. 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.
  2. RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.
  3. ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy.
  4. ISE's native AD integration depends on DNS discovery and communication with eligible domain services, not just a username and password.

Explanation

Correct Answer

C:

ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy. This behavior directly governs the stated requirement. The recommended action is: Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols. The acceptance result is: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

Incorrect Answers

A:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The repeat risk here is different: Test negative authentication cases during directory-failover policy reviews. A directly relevant preventive control is: ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy.

B:

Include CoA reachability and session-identity checks in wireless integration acceptance tests. The repeat risk here is different: Test negative authentication cases during directory-failover policy reviews. A directly relevant preventive control is: ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy.

D:

Separate initial-node bootstrap rights from production policy-administration privileges. The repeat risk here is different: Test negative authentication cases during directory-failover policy reviews. A directly relevant preventive control is: ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy.

Question 125

A campus and branch network operator reports: Employees connect to an 802.1X wireless SSID, but the WLC sends RADIUS requests using a source IP not registered as a network device in ISE. Which measurable outcome proves the intended behavior?

  1. The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.
  2. A posture transition triggers reauthorization and the WLC applies the new role without requiring an unrelated controller restart.
  3. A test wireless session generates a matching accounting start and stop tied to its authenticated identity.
  4. An unrecognized laptop cannot reach protected destinations, and a managed authenticated laptop obtains its authorized access.

Explanation

Correct Answer

A:

The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject. The required remediation is: Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols. It works because iSE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy.

Incorrect Answers

B:

Include CoA reachability and session-identity checks in wireless integration acceptance tests. The actual fault is governed by a different mechanism: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The needed response is: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

C:

Monitor accounting packet delivery separately from successful authentication counts. The actual fault is governed by a different mechanism: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The needed response is: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

D:

Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The actual fault is governed by a different mechanism: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The needed response is: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

Question 126

A Cisco ISE operations team investigates this site issue: Employees connect to an 802.1X wireless SSID, but the WLC sends RADIUS requests using a source IP not registered as a network device in ISE. Which ongoing practice is most appropriate for this failure mode?

  1. Monitor accounting packet delivery separately from successful authentication counts.
  2. Include CoA reachability and session-identity checks in wireless integration acceptance tests.
  3. Verify RADIUS source interfaces after controller failover, redundancy, or interface changes.
  4. Test policy-set selection on each NAD and access medium before enabling broad changes.

Explanation

Correct Answer

C:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. This control addresses recurrence of the observed failure. The governing behavior is: ISE uses the sending network access device's identity and shared secret to validate RADIUS requests before applying wireless authentication policy. The ongoing acceptance check remains: The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.

Incorrect Answers

A:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The offered choice instead concerns a different principle: Monitor accounting packet delivery separately from successful authentication counts. Those technical conditions are not interchangeable.

B:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The offered choice instead concerns a different principle: Include CoA reachability and session-identity checks in wireless integration acceptance tests. Those technical conditions are not interchangeable.

D:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The offered choice instead concerns a different principle: Change the authentication and authorization exception actions to controlled denial or strictly limited approved critical access. Those technical conditions are not interchangeable.

Question 127

During a Cisco ISE postchange review, the following is observed: A campus mandates certificate-only corporate Wi-Fi, but its pilot SSID still allows password-based PEAP in an overly broad allowed-protocol set. Which response most directly corrects the described failure?

  1. Enable supported RADIUS accounting from the controller and confirm the necessary accounting server settings and message path.
  2. Register the actual controller RADIUS source address in ISE, configure matching shared secrets, and associate the correct allowed protocols.
  3. Retrieve the eligible AD groups and include the correct group in ISE's configured AD identity-source group selections and authorization conditions.
  4. Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules.

Explanation

Correct Answer

D:

Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules. This is appropriate because 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used. It should be verified by this evidence: A valid managed EAP-TLS client joins and a password-only test client does not meet the secure SSID policy.

Incorrect Answers

A:

Include CoA reachability and session-identity checks in wireless integration acceptance tests. In the case being tested, Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The necessary acceptance evidence is: Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules.

B:

Test negative authentication cases during directory-failover policy reviews. In the case being tested, Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The necessary acceptance evidence is: Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules.

C:

Include DNS locator and domain connectivity checks in ISE node renumbering. In the case being tested, Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The necessary acceptance evidence is: Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules.

Question 128

A security policy owner must resolve this specific case: A campus mandates certificate-only corporate Wi-Fi, but its pilot SSID still allows password-based PEAP in an overly broad allowed-protocol set. Which statement best explains why the correct response works?

  1. RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.
  2. An existing 802.1X session does not automatically renegotiate its authorization until a supported reauthentication or CoA path occurs.
  3. Identity-source failover must not turn a directory error into unconditional account acceptance; the authorization decision still requires validated identity.
  4. 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.

Explanation

Correct Answer

D:

802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used. This behavior directly governs the stated requirement. The recommended action is: Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules. The acceptance result is: A valid managed EAP-TLS client joins and a password-only test client does not meet the secure SSID policy.

Incorrect Answers

A:

Include CoA reachability and session-identity checks in wireless integration acceptance tests. The repeat risk here is different: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. A directly relevant preventive control is: 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.

B:

Test SSID and network-device-group conditions in each wireless authorization policy set. The repeat risk here is different: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. A directly relevant preventive control is: 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.

C:

Document and test certificate naming conventions during enrollment-template changes. The repeat risk here is different: Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. A directly relevant preventive control is: 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.

Question 129

A network identity engineer receives the following requirement: A campus mandates certificate-only corporate Wi-Fi, but its pilot SSID still allows password-based PEAP in an overly broad allowed-protocol set. Which observation would BEST verify successful remediation?

  1. The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.
  2. A valid managed EAP-TLS client joins and a password-only test client does not meet the secure SSID policy.
  3. A test wireless session generates a matching accounting start and stop tied to its authenticated identity.
  4. The PSN joins the intended domain and a known AD test account authenticates through the correct identity source.

Explanation

Correct Answer

B:

A valid managed EAP-TLS client joins and a password-only test client does not meet the secure SSID policy. The required remediation is: Scope the wireless 802.1X policy to approved EAP-TLS methods and compatible client certificate trust and identity rules. It works because 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.

Incorrect Answers

Question 130

An enterprise access-control incident describes: A campus mandates certificate-only corporate Wi-Fi, but its pilot SSID still allows password-based PEAP in an overly broad allowed-protocol set. What should be incorporated into the change checklist?

  1. Test SSID and network-device-group conditions in each wireless authorization policy set.
  2. Include CoA reachability and session-identity checks in wireless integration acceptance tests.
  3. Test policy-set selection on each NAD and access medium before enabling broad changes.
  4. Audit EAP method availability and certificate trust before deploying new WLANs.

Explanation

Correct Answer

D:

Audit EAP method availability and certificate trust before deploying new WLANs. This control addresses recurrence of the observed failure. The governing behavior is: 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used. The ongoing acceptance check remains: A valid managed EAP-TLS client joins and a password-only test client does not meet the secure SSID policy.
