Cisco 300-715 Practice Test 67
Question 660
A remote VLAN relay uses an unexpected forwarding path and ISE cannot distinguish phone and desktop attributes. The observed failure is: A normal DHCP lease proves address assignment but not that ISE observed the profiling request. Which remediation resolves the underlying fault while maintaining policy?
- The supported recovery is to treat a MAC address as proof of an unchangeable endpoint platform.
- The supported recovery is to repair DHCP probe reachability and verify captured option attributes and profile classification.
- The supported recovery is to assume the DHCP server name alone identifies a phone device.
- The supported recovery is to disable IP helper and expect ISE to receive every remote DHCP broadcast.
Explanation
Correct Answer
B:DHCP option and vendor-class evidence can help profile endpoints when sensor traffic reaches the ISE probe. Recheck dHCP helper path, request option fields, ISE probe status, attribute timeline and endpoint profile.
Incorrect Answers
A:Treat a MAC address as proof of an unchangeable endpoint platform. This action does not repair the identified failure. A normal DHCP lease proves address assignment but not that ISE observed the profiling request. Instead, repair DHCP probe reachability and verify captured option attributes and profile classification. For the specific situation, a remote VLAN relay uses an unexpected forwarding path and ISE cannot distinguish phone and desktop attributes.
C:Assume the DHCP server name alone identifies a phone device. This action does not repair the identified failure. A normal DHCP lease proves address assignment but not that ISE observed the profiling request. Instead, repair DHCP probe reachability and verify captured option attributes and profile classification. For the specific situation, a remote VLAN relay uses an unexpected forwarding path and ISE cannot distinguish phone and desktop attributes.
D:Disable IP helper and expect ISE to receive every remote DHCP broadcast. This action does not repair the identified failure. A normal DHCP lease proves address assignment but not that ISE observed the profiling request.

For the specific situation, a remote VLAN relay uses an unexpected forwarding path and ISE cannot distinguish phone and desktop attributes.
Question 661
A switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details. Which administrator action is appropriate for this ISE access-control problem?
- Configure appropriate RADIUS accounting and ensure supported attributes reach the correct ISE service.
- Assume a successful Access-Accept implies all session accounting was delivered.
- Turn off switch accounting to reduce profiling delays.
- Use only the switch configuration description as current endpoint attachment evidence.
Explanation
Correct Answer
A:Verify the effect through start and interim accounting records, Calling-Station-ID, NAS-IP, interface ID and received attributes. For the specific situation, a switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details.
Incorrect Answers
B:This does not implement the required control for RADIUS probe accounting attributes for profiling. Missing accounting limits profiling and session tracking even when user logins succeed.
C:Turn off switch accounting to reduce profiling delays. This alternative overlooks a required prerequisite or targets the wrong function. RADIUS accounting contributes session and attachment telemetry separate from initial authentication decisions. The relevant evidence is start and interim accounting records, Calling-Station-ID, NAS-IP, interface ID and received attributes. For the specific situation, a switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details.
D:Missing accounting limits profiling and session tracking even when user logins succeed. For the specific situation, a switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details.
Question 662
A switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details. Which collected records establish that the ISE decision actually took effect?

- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- A current login screenshot from a completely unrelated ISE deployment.

Question 664
A switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details. An operator proposes the following incorrect shortcut: Assume a successful Access-Accept implies all session accounting was delivered. What specific security or operational failure should be anticipated?
- Reading the authentication event report caused the original network access outage.
- Missing accounting limits profiling and session tracking even when user logins succeed.
- The only result is an unrelated portal background color change.
- Accurate device accounting automatically created every earlier failed EAP exchange.
Explanation
Correct Answer
B:The shortcut is unsuitable because rADIUS accounting contributes session and attachment telemetry separate from initial authentication decisions. For the specific situation, a switch sends Access-Requests but no accounting messages and ISE endpoint inventory lacks session and location details.
