Question 140

During a Cisco ISE postchange review, the following is observed: A wireless 802.1X rollout has successful connections but no traceable per-user session-end accounting in ISE when users disconnect. Which architectural fact determines the appropriate fix?

  1. An existing 802.1X session does not automatically renegotiate its authorization until a supported reauthentication or CoA path occurs.
  2. RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.
  3. 802.1X is the access framework; its selected EAP method determines whether certificates or password-based credential exchange is used.
  4. An AD account authentication does not automatically cause every directory group to become available in ISE authorization rules.

Explanation

Correct Answer

B:

RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured. This behavior directly governs the stated requirement. The recommended action is: Enable supported RADIUS accounting from the controller and confirm the necessary accounting server settings and message path. The acceptance result is: A test wireless session generates a matching accounting start and stop tied to its authenticated identity.

Incorrect Answers

A:

Test SSID and network-device-group conditions in each wireless authorization policy set. The repeat risk here is different: Include CoA reachability and session-identity checks in wireless integration acceptance tests. A directly relevant preventive control is: RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.

C:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The repeat risk here is different: Include CoA reachability and session-identity checks in wireless integration acceptance tests. A directly relevant preventive control is: RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.

D:

Include DNS locator and domain connectivity checks in ISE node renumbering. The repeat risk here is different: Include CoA reachability and session-identity checks in wireless integration acceptance tests. A directly relevant preventive control is: RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.

Question 141

A security policy owner must resolve this specific case: A wireless 802.1X rollout has successful connections but no traceable per-user session-end accounting in ISE when users disconnect. Which postchange outcome demonstrates correct implementation?

  1. A test wireless session generates a matching accounting start and stop tied to its authenticated identity.
  2. The WLC's pilot association creates an ISE live-log entry under its intended NAD object and receives a valid Access-Accept or Reject.
  3. A posture transition triggers reauthorization and the WLC applies the new role without requiring an unrelated controller restart.
  4. The approved printer reaches its print server and an unregistered MAC cannot access the protected network.

Explanation

Correct Answer

A:

A test wireless session generates a matching accounting start and stop tied to its authenticated identity. The required remediation is: Enable supported RADIUS accounting from the controller and confirm the necessary accounting server settings and message path. It works because rADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured.

Incorrect Answers

B:

Verify RADIUS source interfaces after controller failover, redundancy, or interface changes. The actual fault is governed by a different mechanism: Monitor accounting packet delivery separately from successful authentication counts. The needed response is: A test wireless session generates a matching accounting start and stop tied to its authenticated identity.

C:

Include CoA reachability and session-identity checks in wireless integration acceptance tests. The actual fault is governed by a different mechanism: Monitor accounting packet delivery separately from successful authentication counts. The needed response is: A test wireless session generates a matching accounting start and stop tied to its authenticated identity.

D:

Register the printer's endpoint MAC as an authorized internal endpoint and configure a tightly scoped MAB authorization profile. The actual fault is governed by a different mechanism: Monitor accounting packet delivery separately from successful authentication counts. The needed response is: A test wireless session generates a matching accounting start and stop tied to its authenticated identity.

Question 142

A network identity engineer receives the following requirement: A wireless 802.1X rollout has successful connections but no traceable per-user session-end accounting in ISE when users disconnect. What should be added to the maintenance or security review?

  1. Monitor accounting packet delivery separately from successful authentication counts.
  2. Test SSID and network-device-group conditions in each wireless authorization policy set.
  3. Verify RADIUS source interfaces after controller failover, redundancy, or interface changes.
  4. Maintain per-directory schema mapping tests before identity store migrations.

Explanation

Correct Answer

A:

Monitor accounting packet delivery separately from successful authentication counts. This control addresses recurrence of the observed failure. The governing behavior is: RADIUS authentication exchanges grant access, while accounting records session start, stop, and interim usage events when configured. The ongoing acceptance check remains: A test wireless session generates a matching accounting start and stop tied to its authenticated identity.

Incorrect Answers

B:

Monitor accounting packet delivery separately from successful authentication counts. The offered choice instead concerns a different principle: Test SSID and network-device-group conditions in each wireless authorization policy set. Those technical conditions are not interchangeable.

C:

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

D:

Monitor accounting packet delivery separately from successful authentication counts. The offered choice instead concerns a different principle: Maintain per-directory schema mapping tests before identity store migrations. Those technical conditions are not interchangeable.

Question 143

A campus and branch network operator reports: During the first wired 802.1X rollout, administrators want to observe endpoint identity decisions without interrupting production workstations, but the new switch configuration blocks unknown devices immediately. What is the most appropriate next configuration or repair?

  1. Use multi-auth host mode where supported and require each downstream client to authenticate individually.
  2. Select a supported 802.1X host mode such as multi-domain when one voice endpoint and one data endpoint must authenticate separately.
  3. Use a supported session reauthentication or RADIUS CoA after the endpoint identity and profile classification change.
  4. Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization.

Explanation

Correct Answer

D:

Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization. This is appropriate because monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt. It should be verified by this evidence: Access logs show which endpoint identities would authenticate while pilot users retain the defined non-disruptive connectivity.

Incorrect Answers

A:

Use multi-auth host mode where supported and require each downstream client to authenticate individually. In the case being tested, Monitor accounting packet delivery separately from successful authentication counts. The necessary acceptance evidence is: Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization.

B:

Select a supported 802.1X host mode such as multi-domain when one voice endpoint and one data endpoint must authenticate separately. In the case being tested, Monitor accounting packet delivery separately from successful authentication counts. The necessary acceptance evidence is: Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization.

C:

Use a supported session reauthentication or RADIUS CoA after the endpoint identity and profile classification change. In the case being tested, Monitor accounting packet delivery separately from successful authentication counts. The necessary acceptance evidence is: Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization.

Question 144

A Cisco ISE operations team investigates this site issue: During the first wired 802.1X rollout, administrators want to observe endpoint identity decisions without interrupting production workstations, but the new switch configuration blocks unknown devices immediately. What is the key technical principle in this situation?

  1. An authentication-server-unavailable event can invoke configured IBNS 2.0 service templates; it should not be confused with a successful identity decision.
  2. IBNS 2.0 authentication policy can orchestrate multiple methods; an endpoint without EAPOL support needs an alternate admission mechanism.
  3. Kerberos and certificate-related authentication paths depend on appropriate time consistency; network reachability alone does not eliminate clock-related failures.
  4. Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt.

Explanation

Correct Answer

D:

Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt. This behavior directly governs the stated requirement. The recommended action is: Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization. The acceptance result is: Access logs show which endpoint identities would authenticate while pilot users retain the defined non-disruptive connectivity.

Incorrect Answers

A:

Define an explicit critical-authentication event action and constrained access policy for loss of all authorized RADIUS servers. The repeat risk here is different: Monitor accounting packet delivery separately from successful authentication counts. A directly relevant preventive control is: Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt.

B:

Add an explicitly authorized MAB method and appropriate event-driven policy handling for devices that cannot perform 802.1X. The repeat risk here is different: Monitor accounting packet delivery separately from successful authentication counts. A directly relevant preventive control is: Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt.

C:

Run cross-domain sign-in regression tests when adding or replacing PSNs. The repeat risk here is different: Monitor accounting packet delivery separately from successful authentication counts. A directly relevant preventive control is: Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt.

Question 145

At a distributed Cisco ISE deployment, a security review finds: During the first wired 802.1X rollout, administrators want to observe endpoint identity decisions without interrupting production workstations, but the new switch configuration blocks unknown devices immediately. Which ongoing practice is most appropriate for this failure mode?

  1. Maintain explicit exit criteria and a dated transition from monitor to enforced modes.
  2. Standardize host-mode profiles for phone-plus-PC access ports.
  3. Test essential control-plane exceptions before enforcing closed mode at scale.
  4. Test external MFA service failures and document secure fail-closed or permitted exception behavior.

Explanation

Correct Answer

A:

Maintain explicit exit criteria and a dated transition from monitor to enforced modes. This control addresses recurrence of the observed failure. The governing behavior is: Monitor mode allows phased assessment of client and policy readiness without immediately denying productive access on every failed attempt. The ongoing acceptance check remains: Access logs show which endpoint identities would authenticate while pilot users retain the defined non-disruptive connectivity.

Incorrect Answers

B:

Use multi-auth host mode where supported and require each downstream client to authenticate individually. The actual fault is governed by a different mechanism: Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The needed response is: Maintain explicit exit criteria and a dated transition from monitor to enforced modes.

C:

Select a supported 802.1X host mode such as multi-domain when one voice endpoint and one data endpoint must authenticate separately. The actual fault is governed by a different mechanism: Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The needed response is: Maintain explicit exit criteria and a dated transition from monitor to enforced modes.

D:

Test external MFA service failures and document secure fail-closed or permitted exception behavior. The actual fault is governed by a different mechanism: Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The needed response is: Maintain explicit exit criteria and a dated transition from monitor to enforced modes.

Question 146

A network identity engineer receives the following requirement: A migration pilot must allow only DHCP, DNS, and the ISE onboarding portal before authentication, yet unauthorized clients currently reach all enterprise subnets. Which implementation decision directly satisfies the stated requirement?

  1. Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions.
  2. Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services.
  3. Define an explicit critical-authentication event action and constrained access policy for loss of all authorized RADIUS servers.
  4. Use approved TrustSec policy distribution and verify that devices receive and enforce the current SGACL definition and matrix updates.

Explanation

Correct Answer

B:

Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. This is appropriate because low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision. It should be verified by this evidence: An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision.

Incorrect Answers

A:

Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The offered choice instead concerns a different principle: Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. Those technical conditions are not interchangeable.

C:

Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The offered choice instead concerns a different principle: Define an explicit critical-authentication event action and constrained access policy for loss of all authorized RADIUS servers. Those technical conditions are not interchangeable.

D:

The offered choice instead concerns a different principle: Use approved TrustSec policy distribution and verify that devices receive and enforce the current SGACL definition and matrix updates. Those technical conditions are not interchangeable.

Question 147

An enterprise access-control incident describes: A migration pilot must allow only DHCP, DNS, and the ISE onboarding portal before authentication, yet unauthorized clients currently reach all enterprise subnets. Which technical behavior is MOST relevant to this design?

  1. Host mode governs how many endpoint sessions and traffic domains may coexist on one access port; single-host can reject additional devices.
  2. Event-driven IBNS 2.0 control policy governs how authentication state changes after RADIUS events; a static VLAN command alone does not define transitions.
  3. Authentication establishes identity, whereas ordered authorization policy selects an access result based on conditions; rule precedence is decisive.
  4. Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

Explanation

Correct Answer

D:

Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision. This behavior directly governs the stated requirement. The recommended action is: Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The acceptance result is: An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision.

Incorrect Answers

A:

Select a supported 802.1X host mode such as multi-domain when one voice endpoint and one data endpoint must authenticate separately. In the case being tested, Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The necessary acceptance evidence is: Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

B:

Inspect the IBNS 2.0 event and action mapping for reauthentication and apply a supported CoA-triggered session transition. In the case being tested, Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The necessary acceptance evidence is: Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

C:

Reorder and constrain the ISE authorization rules so the intended matching condition precedes the broad fallback deny. In the case being tested, Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. The necessary acceptance evidence is: Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

Question 148

In a staged Cisco ISE network access rollout, the team observes: A migration pilot must allow only DHCP, DNS, and the ISE onboarding portal before authentication, yet unauthorized clients currently reach all enterprise subnets. Which readback demonstrates that the actual problem was solved?

  1. During a controlled PSN outage, the port applies only the approved critical-access template and returns to normal authorization afterward.
  2. An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision.
  3. An approved CoA request causes the target port session to reauthenticate and receive fresh ISE authorization.
  4. The PSN joins the intended domain and a known AD test account authenticates through the correct identity source.

Explanation

Correct Answer

B:

An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision. The required remediation is: Use a carefully scoped low-impact 802.1X design with a preauthentication ACL limited to required bootstrap services. It works because low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision.

A directly relevant preventive control is: An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision.

Question 149

An identity and device-administration engineer evaluates: A migration pilot must allow only DHCP, DNS, and the ISE onboarding portal before authentication, yet unauthorized clients currently reach all enterprise subnets. What validation should be repeated before subsequent rollouts?

  1. Review host-mode risk before permitting attached mini-switches.
  2. Audit preauthentication ACL exceptions as the rollout moves from low impact to closed enforcement.
  3. Maintain explicit exit criteria and a dated transition from monitor to enforced modes.
  4. Track EAP certificate chain, identity mapping, and renewal as distinct controls.

Explanation

Correct Answer

B:

Audit preauthentication ACL exceptions as the rollout moves from low impact to closed enforcement. This control addresses recurrence of the observed failure. The governing behavior is: Low-impact mode permits constrained preliminary access while authentication completes, unlike granting unrestricted traffic before the ISE decision. The ongoing acceptance check remains: An unauthenticated client obtains only approved bootstrap services and receives full permitted access after a successful 802.1X decision.

Incorrect Answers

A:

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: Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The needed response is: Audit preauthentication ACL exceptions as the rollout moves from low impact to closed enforcement.

C:

The actual fault is governed by a different mechanism: Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The needed response is: Audit preauthentication ACL exceptions as the rollout moves from low impact to closed enforcement.

D:

The actual fault is governed by a different mechanism: Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The needed response is: Audit preauthentication ACL exceptions as the rollout moves from low impact to closed enforcement.

Question 150

An ISE administrator troubleshoots the following: A regulated lab requires all regular user traffic denied until an endpoint has successfully completed authentication; the current open authorization permits unverified traffic. What should the team change before declaring this work complete?

  1. Use a supported monitor-mode 802.1X deployment to collect authentication evidence before enforcing restrictive authorization.
  2. Use multi-auth host mode where supported and require each downstream client to authenticate individually.
  3. Configure supported LDAP over TLS with a trusted server certificate and the correct bind identity and search configuration.
  4. Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions.

Explanation

Correct Answer

D:

Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. This is appropriate because closed mode restricts ordinary data access before a valid authentication result, enforcing the port's intended admission barrier. It should be verified by this evidence: An unrecognized laptop cannot reach protected destinations, and a managed authenticated laptop obtains its authorized access.

Incorrect Answers

A:

Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The offered choice instead concerns a different principle: Monitor accounting packet delivery separately from successful authentication counts. Those technical conditions are not interchangeable.

B:

Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The offered choice instead concerns a different principle: Use multi-auth host mode where supported and require each downstream client to authenticate individually. Those technical conditions are not interchangeable.

C:

Apply an appropriate closed-mode wired 802.1X configuration with necessary tightly controlled exceptions. The offered choice instead concerns a different principle: Validate directory organizational-unit moves against ISE LDAP search filters before cutover. Those technical conditions are not interchangeable.
