Cisco 300-715 Practice Test 114
Question 1130
An operations team enables device admin configuration without confirming the necessary Cisco license and service role. The observed failure is: An appliance serving endpoints cannot necessarily process TACACS+ until authorized functionality is available. How should the administrator correct and verify this failure?
- The supported recovery is to use an endpoint-profile license display name as proof TACACS+ is active.
- The supported recovery is to assume all ISE installs include device-admin licensing without checking entitlement.
- The supported recovery is to disable all PSNs and expect command authorization to continue.
- The supported recovery is to correct licensing and service assignments then validate a network device administrator login.
Explanation
Correct Answer
D:This restores the intended operational behavior for TACACS device-admin service licensing. For the specific situation, an operations team enables device admin configuration without confirming the necessary Cisco license and service role.
Incorrect Answers
A:Use an endpoint-profile license display name as proof TACACS+ is active. This action does not repair the identified failure. An appliance serving endpoints cannot necessarily process TACACS+ until authorized functionality is available. Instead, correct licensing and service assignments then validate a network device administrator login. For the specific situation, an operations team enables device admin configuration without confirming the necessary Cisco license and service role.

Question 1131
A switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device. Which configuration decision most directly satisfies the requirement?
- Use the logged-in employee password as the TACACS device shared secret.
- Register only the switch hostname while its actual client source IP differs.
- Register each NAD source and matching TACACS+ shared secret, with permitted protocol and service reachability.
- Disable shared-secret checks throughout device administration.
Explanation
Correct Answer
C:TACACS+ requires a recognized client and shared secret consistent with both the device and server. For the specific situation, a switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device.
Incorrect Answers
A:This does not implement the required control for Network device TACACS shared secret and client registration. A correct employee password cannot make an unrecognized device a trusted TACACS client.
B:Register only the switch hostname while its actual client source IP differs. This alternative overlooks a required prerequisite or targets the wrong function. TACACS+ requires a recognized client and shared secret consistent with both the device and server. The relevant evidence is tACACS source IP, ISE network device object, shared secret verification, TCP connection and live authentication result. For the specific situation, a switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device.
D:A correct employee password cannot make an unrecognized device a trusted TACACS client. For the specific situation, a switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device.
Question 1132
A switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device. What observations most directly test this network-access condition?
- TACACS source IP, ISE network device object, shared secret verification, TCP connection and live authentication result.
- A device hostname alone without the policy result or authenticated source.
- A current login screenshot from a completely unrelated ISE deployment.
- A browser theme label without a current authorization trace.
Explanation
Correct Answer
A:TACACS+ requires a recognized client and shared secret consistent with both the device and server. These observations directly establish the result of Network device TACACS shared secret and client registration for the described endpoint or network device.
Incorrect Answers
B:A device hostname alone without the policy result or authenticated source. This observation cannot verify Network device TACACS shared secret and client registration. Check tACACS source IP, ISE network device object, shared secret verification, TCP connection and live authentication result.

Question 1133
A switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device. What principle of ISE authentication and authorization explains this case?
- A successful switch port link signal always proves the device identity and policy were verified.
- All Cisco ISE administration and policy personas perform exactly the same service.
- A policy display name alone is the complete source of enforcement state.
- TACACS+ requires a recognized client and shared secret consistent with both the device and server.
Explanation

Question 1134
A switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device. An operator proposes the following incorrect shortcut: Use the logged-in employee password as the TACACS device shared secret. Which negative consequence BEST explains the shortcut’s flaw?
- A correct employee password cannot make an unrecognized device a trusted TACACS client.
- A justified least-privilege ACL caused every unrelated network authentication fault.
- A correctly recorded TACACS command audit caused the preceding security violation.
- Reading the authentication event report caused the original network access outage.
Explanation
Correct Answer
A:The shortcut is unsuitable because tACACS+ requires a recognized client and shared secret consistent with both the device and server. For the specific situation, a switch sends TACACS requests to ISE but the request is rejected because its source IP was not added as a network device.
Incorrect Answers
B:This unrelated assertion does not explain the Network device TACACS shared secret and client registration problem. The relevant risk is that a correct employee password cannot make an unrecognized device a trusted TACACS client.
