Question 30

An enterprise access-control incident describes: A regional ISE deployment uses a primary and secondary PSN but the load balancer health check passes when HTTPS is up even though RADIUS processing has stopped. Which postchange outcome demonstrates correct implementation?

  1. A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.
  2. When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out.
  3. Sizing records show supported node capacities and a representative peak-load trial meets the authentication latency objective.
  4. The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

Explanation

Correct Answer

B:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The required remediation is: Use health checks and client failover behavior that validate supported AAA processing rather than merely the management web listener. It works because web management availability and RADIUS decision-service availability are separate health signals.

Incorrect Answers

A:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The offered choice instead concerns a different principle: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. Those technical conditions are not interchangeable.

C:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The offered choice instead concerns a different principle: Sizing records show supported node capacities and a representative peak-load trial meets the authentication latency objective. Those technical conditions are not interchangeable.

D:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The offered choice instead concerns a different principle: the VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. Those technical conditions are not interchangeable.

Question 31

In a staged Cisco ISE network access rollout, the team observes: A regional ISE deployment uses a primary and secondary PSN but the load balancer health check passes when HTTPS is up even though RADIUS processing has stopped. What should be added to the maintenance or security review?

  1. Re-evaluate deployment mode when endpoint count, authentication load, or availability requirements grow.
  2. Check supported load-balancing design and preserve RADIUS source identity when changing AAA topology.
  3. Validate production health checks against the actual services used by switches and controllers.
  4. Review pxGrid service placement and client trust separately from RADIUS policy coverage.

Explanation

Correct Answer

C:

Validate production health checks against the actual services used by switches and controllers. This control addresses recurrence of the observed failure. The governing behavior is: Web management availability and RADIUS decision-service availability are separate health signals. The ongoing acceptance check remains: When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out.

Incorrect Answers

A:

One laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. In the case being tested, When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The necessary acceptance evidence is: Validate production health checks against the actual services used by switches and controllers.

B:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. In the case being tested, When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The necessary acceptance evidence is: Validate production health checks against the actual services used by switches and controllers.

D:

pxGrid publishes contextual identity and security information to integrations; the ordinary RADIUS access service is not a substitute for pxGrid messaging. In the case being tested, When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The necessary acceptance evidence is: Validate production health checks against the actual services used by switches and controllers.

Question 32

At a distributed Cisco ISE deployment, a security review finds: Security teams plan to put all remote ISE nodes behind a stateless TCP proxy and assume session and device identity remain correct without evaluating Cisco support. What is the most appropriate next configuration or repair?

  1. Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology.
  2. Use a supported standalone ISE deployment for the lab while acknowledging its single-node failure exposure.
  3. Use health checks and client failover behavior that validate supported AAA processing rather than merely the management web listener.
  4. Check supported hypervisor CPU, memory reservation, storage I/O, and resource contention before changing authentication rules.

Explanation

Correct Answer

A:

Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology. This is appropriate because iSE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path. It should be verified by this evidence: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs.

Incorrect Answers

B:

A test authorization succeeds through the alternate PSN after the first PSN becomes unavailable. The repeat risk here is different: When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. A directly relevant preventive control is: Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology.

C:

Sizing records show supported node capacities and a representative peak-load trial meets the authentication latency objective. The repeat risk here is different: When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. A directly relevant preventive control is: Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology.

D:

Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial. The repeat risk here is different: When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. A directly relevant preventive control is: Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology.

Question 33

An ISE administrator troubleshoots the following: Security teams plan to put all remote ISE nodes behind a stateless TCP proxy and assume session and device identity remain correct without evaluating Cisco support. What is the key technical principle in this situation?

  1. ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.
  2. A standalone node can provide Administration, Policy Service, and Monitoring personas for limited environments; scale and resilience drive distributed designs.
  3. Web management availability and RADIUS decision-service availability are separate health signals.
  4. Monitoring storage requirements differ with event volume and retention; free capacity may be exhausted even when RADIUS authentication still succeeds.

Explanation

Correct Answer

A:

ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path. This behavior directly governs the stated requirement. The recommended action is: Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology. The acceptance result is: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs.

Incorrect Answers

B:

One laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. The actual fault is governed by a different mechanism: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The needed response is: ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.

C:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The actual fault is governed by a different mechanism: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The needed response is: ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.

D:

Monitoring node retains the defined reporting period without disk threshold alerts under a realistic log-rate trial. The actual fault is governed by a different mechanism: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The needed response is: ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.

Question 34

An access-security change request states: Security teams plan to put all remote ISE nodes behind a stateless TCP proxy and assume session and device identity remain correct without evaluating Cisco support. What result should be documented before closing the issue?

  1. When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out.
  2. A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.
  3. Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs.
  4. The appliance completes first boot with its intended hostname, management network, and registered system state without interactive setup.

Explanation

Correct Answer

C:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The required remediation is: Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology. It works because iSE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.

Incorrect Answers

A:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The offered choice instead concerns a different principle: When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out.

The offered choice instead concerns a different principle: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. Those technical conditions are not interchangeable.

D:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The offered choice instead concerns a different principle: Validate bootstrap DNS, access, and device identity against a clean installation before rollout. Those technical conditions are not interchangeable.

Question 35

During a Cisco ISE postchange review, the following is observed: Security teams plan to put all remote ISE nodes behind a stateless TCP proxy and assume session and device identity remain correct without evaluating Cisco support. Which durable safeguard best prevents a recurrence?

  1. Check supported load-balancing design and preserve RADIUS source identity when changing AAA topology.
  2. Include concurrency, device count, log volume, and failover capacity in deployment sizing reviews.
  3. Validate production health checks against the actual services used by switches and controllers.
  4. Add DNS and NTP acceptance tests to the automated provisioning pipeline.

Explanation

Correct Answer

A:

Check supported load-balancing design and preserve RADIUS source identity when changing AAA topology. This control addresses recurrence of the observed failure. The governing behavior is: ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path. The ongoing acceptance check remains: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs.

In the case being tested, Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. The necessary acceptance evidence is: Check supported load-balancing design and preserve RADIUS source identity when changing AAA topology.

Question 36

In a staged Cisco ISE network access rollout, the team observes: Two datacenters have independent ISE installations and a team assumes policy changes will automatically replicate between the separate deployments. Which implementation decision directly satisfies the stated requirement?

  1. Size and distribute PAN, PSN, and Monitoring services using published deployment scale and throughput limits for the target release.
  2. Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles.
  3. Use Cisco-supported ISE load distribution and RADIUS source-address handling rather than an unvalidated generic proxy topology.
  4. Separate central Policy Administration Node responsibilities from appropriate Policy Service Nodes, and distribute RADIUS requests to healthy PSNs.

Explanation

Correct Answer

B:

Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles. This is appropriate because separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain. It should be verified by this evidence: A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.

Incorrect Answers

A:

One laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. The repeat risk here is different: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. A directly relevant preventive control is: Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles.

C:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. The repeat risk here is different: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. A directly relevant preventive control is: Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles.

D:

The PAN manages configuration while PSNs process live network-access authentication; co-locating them creates a common maintenance failure point. The repeat risk here is different: Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. A directly relevant preventive control is: Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles.

Question 37

An identity and device-administration engineer evaluates: Two datacenters have independent ISE installations and a team assumes policy changes will automatically replicate between the separate deployments. Which technical behavior is MOST relevant to this design?

  1. Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain.
  2. Successful low-load authentication does not establish capacity for an enterprise's peak concurrent RADIUS and profiling workload.
  3. ISE policy and device selection can depend on NAD identity and actual RADIUS request context; arbitrary intermediaries can alter the intended authentication path.
  4. Reusing bootstrap secrets across appliances increases credential exposure and can bind a node to the wrong identity.

Explanation

Correct Answer

A:

Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain. This behavior directly governs the stated requirement. The recommended action is: Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles. The acceptance result is: A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.

Incorrect Answers

B:

Sizing records show supported node capacities and a representative peak-load trial meets the authentication latency objective. The actual fault is governed by a different mechanism: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The needed response is: Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain.

The actual fault is governed by a different mechanism: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The needed response is: Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain.

D:

Validate bootstrap DNS, access, and device identity against a clean installation before rollout. The actual fault is governed by a different mechanism: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The needed response is: Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain.

Question 38

A campus and branch network operator reports: Two datacenters have independent ISE installations and a team assumes policy changes will automatically replicate between the separate deployments. Which readback demonstrates that the actual problem was solved?

  1. One laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs.
  2. Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs.
  3. A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.
  4. The new node is bootstrapped with its intended system settings while existing authorization policies change only through approved PAN operations.

Explanation

Correct Answer

C:

A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The required remediation is: Register nodes into one supported distributed deployment when central configuration synchronization is required, or explicitly manage independent policy lifecycles. It works because separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain.

Incorrect Answers

A:

A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The offered choice instead concerns a different principle: one laboratory node manages policy, answers test RADIUS requests, and records corresponding live logs. Those technical conditions are not interchangeable.

B:

Those technical conditions are not interchangeable.

D:

A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The offered choice instead concerns a different principle: Separate initial-node bootstrap rights from production policy-administration privileges. Those technical conditions are not interchangeable.

Question 39

A Cisco ISE operations team investigates this site issue: Two datacenters have independent ISE installations and a team assumes policy changes will automatically replicate between the separate deployments. What validation should be repeated before subsequent rollouts?

  1. Keep deployment membership, replication state, and ownership boundaries recorded.
  2. Validate production health checks against the actual services used by switches and controllers.
  3. Check supported load-balancing design and preserve RADIUS source identity when changing AAA topology.
  4. Monitor virtualization resource contention as a separate failure domain from policy correctness.

Explanation

Correct Answer

A:

Keep deployment membership, replication state, and ownership boundaries recorded. This control addresses recurrence of the observed failure. The governing behavior is: Separate ISE deployments are not automatically one replicated PAN/PSN cluster merely because they share an AD domain. The ongoing acceptance check remains: A permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations.

Incorrect Answers

B:

When one PSN's AAA service is disabled in a test, fresh authentications move to a healthy node instead of timing out. In the case being tested, a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The necessary acceptance evidence is: Keep deployment membership, replication state, and ownership boundaries recorded.

C:

Test requests from each NAD match the correct ISE network-device object and authorization policy across the balanced PSNs. In the case being tested, a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The necessary acceptance evidence is: Keep deployment membership, replication state, and ownership boundaries recorded.

D:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. In the case being tested, a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. The necessary acceptance evidence is: Keep deployment membership, replication state, and ownership boundaries recorded.

Question 40

During a Cisco ISE postchange review, the following is observed: A new ISE virtual machine boots with fewer vCPUs and less RAM than the Cisco-supported appliance sizing profile while an operator assumes the installation ISO guarantees capacity. What should the team change before declaring this work complete?

  1. Provision Monitoring storage against Cisco's supported node-size, log-rate, and retention guidance instead of using a generic minimal disk image.
  2. Use a hypervisor and installation method explicitly supported for the selected ISE release and appliance image.
  3. Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.
  4. Configure the supported zero-touch provisioning prerequisites including identity, DNS, network reachability, and trusted bootstrap data.

Explanation

Correct Answer

C:

Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources. This is appropriate because iSE VM performance depends on reserved hypervisor capacity and supported resource specifications rather than the ISO image alone. It should be verified by this evidence: The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds.

Incorrect Answers

A:

The VM meets the documented profile and representative authentication load remains within agreed latency and resource thresholds. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.

B:

Host contention clears and RADIUS response times return within the documented service target under the same traffic. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.

D:

Review supported hypervisors and appliance sizing every time an ISE major release is adopted. The repeat risk here is different: a permitted test-policy update reaches all registered nodes in the defined deployment and not unrelated standalone installations. A directly relevant preventive control is: Choose a Cisco-supported virtual-appliance sizing profile and allocate its specified CPU, RAM, disk, and network resources.
