Cisco 300-715 Practice Test 86
Question 850
A campus desktop receives a BYOD certificate but remains under a restricted pre-enrollment dACL. The observed failure is: A missing preauthentication route or authorization refresh can prevent the endpoint reaching its final policy. How should the administrator correct and verify this failure?
- The supported recovery is to permit any unauthenticated wired client into the corporate database VLAN.
- The supported recovery is to assume a switch port label alone launches the BYOD onboarding workflow.
- The supported recovery is to repair switch redirection or reauthorization and validate final access with an approved device.
- The supported recovery is to block all portal DNS and HTTPS before authentication.
Explanation
Correct Answer
C:Recheck switch session, redirect ACL and URL, onboarding portal completion, EAP type and final dACL. For the specific situation, a campus desktop receives a BYOD certificate but remains under a restricted pre-enrollment dACL.
Incorrect Answers
A:Permit any unauthenticated wired client into the corporate database VLAN. This action does not repair the identified failure. A missing preauthentication route or authorization refresh can prevent the endpoint reaching its final policy. Instead, repair switch redirection or reauthorization and validate final access with an approved device. For the specific situation, a campus desktop receives a BYOD certificate but remains under a restricted pre-enrollment dACL.
B:Assume a switch port label alone launches the BYOD onboarding workflow. This action does not repair the identified failure. A missing preauthentication route or authorization refresh can prevent the endpoint reaching its final policy. Instead, repair switch redirection or reauthorization and validate final access with an approved device. For the specific situation, a campus desktop receives a BYOD certificate but remains under a restricted pre-enrollment dACL.
D:Block all portal DNS and HTTPS before authentication. This action does not repair the identified failure. A missing preauthentication route or authorization refresh can prevent the endpoint reaching its final policy. Instead, repair switch redirection or reauthorization and validate final access with an approved device. For the specific situation, a campus desktop receives a BYOD certificate but remains under a restricted pre-enrollment dACL.
Question 851
An onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN. Which configuration decision most directly satisfies the requirement?
- Treat a captive-portal cookie as an EAP-TLS certificate.
- Configure compatible WLC RADIUS policy and native supplicant EAP-TLS after the ISE BYOD onboarding sequence.
- Disable server trust checks to connect an unknown WLAN controller.
- Route every certificate-bearing employee to the guest hotspot indefinitely.
Explanation
Correct Answer
B:BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
Incorrect Answers
A:A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely. This does not implement the required control for Wireless controller BYOD EAP TLS end-state.
C:Disable server trust checks to connect an unknown WLAN controller. This alternative overlooks a required prerequisite or targets the wrong function. BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization. The relevant evidence is wireless RADIUS trace, EAP method, endpoint certificate, policy profile and SSID association. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
D:A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
Question 852
An onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN. What observations most directly test this network-access condition?
- Wireless RADIUS trace, EAP method, endpoint certificate, policy profile and SSID association.
- A successful ICMP echo that does not test the required identity-service workflow.
- A browser theme label without a current authorization trace.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
Explanation
Correct Answer
A:BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization. These observations directly establish the result of Wireless controller BYOD EAP TLS end-state for the described endpoint or network device.
Incorrect Answers
B:This observation cannot verify Wireless controller BYOD EAP TLS end-state. BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization.
C:This observation cannot verify Wireless controller BYOD EAP TLS end-state. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
D:This observation cannot verify Wireless controller BYOD EAP TLS end-state. Check wireless RADIUS trace, EAP method, endpoint certificate, policy profile and SSID association.
Question 853
An onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN. What principle of ISE authentication and authorization explains this case?
- BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization.
- All Cisco ISE administration and policy personas perform exactly the same service.
- A captive portal page automatically changes network authorization on every active NAD session without signaling.
- A MAC address is a cryptographic proof of endpoint device ownership.
Explanation
Correct Answer
A:The supported implementation is to configure compatible WLC RADIUS policy and native supplicant EAP-TLS after the ISE BYOD onboarding sequence. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
Incorrect Answers
B:This generalization is not valid for Wireless controller BYOD EAP TLS end-state. Instead bYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization.
C:This generalization is not valid for Wireless controller BYOD EAP TLS end-state. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
D:This generalization is not valid for Wireless controller BYOD EAP TLS end-state. Verify the actual state using wireless RADIUS trace, EAP method, endpoint certificate, policy profile and SSID association.
Question 854
An onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN. An operator proposes the following incorrect shortcut: Treat a captive-portal cookie as an EAP-TLS certificate. Which negative consequence BEST explains the shortcut’s flaw?
- Accurate device accounting automatically created every earlier failed EAP exchange.
- Inspecting a correct endpoint certificate generated the original directory outage.
- A justified least-privilege ACL caused every unrelated network authentication fault.
- A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely.
Explanation
Correct Answer
D:The shortcut is unsuitable because bYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization. For the specific situation, an onboarding SSID captures employee credentials but the provisioned phone cannot authenticate to the secure WLAN.
Incorrect Answers
A:This unrelated assertion does not explain the Wireless controller BYOD EAP TLS end-state problem. The relevant risk is that a registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely.
