Cisco 300-715 Practice Test 87
Question 860
A WLC uses the wrong ISE authorization profile and sends already-registered BYOD devices to the guest portal. The observed failure is: A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely. Which remediation resolves the underlying fault while maintaining policy?
- The supported recovery is to route every certificate-bearing employee to the guest hotspot indefinitely.
- The supported recovery is to treat a captive-portal cookie as an EAP-TLS certificate.
- The supported recovery is to disable server trust checks to connect an unknown WLAN controller.
- The supported recovery is to correct WLC or supplicant settings and test first and subsequent secure reconnections.
Explanation
Correct Answer
D:BYOD success depends on both the certificate-bearing supplicant and WLC enforcing the final wireless authorization. Recheck wireless RADIUS trace, EAP method, endpoint certificate, policy profile and SSID association.
Incorrect Answers
A:Route every certificate-bearing employee to the guest hotspot indefinitely. This action does not repair the identified failure. A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely. Instead, correct WLC or supplicant settings and test first and subsequent secure reconnections. For the specific situation, a WLC uses the wrong ISE authorization profile and sends already-registered BYOD devices to the guest portal.
B:Treat a captive-portal cookie as an EAP-TLS certificate. This action does not repair the identified failure. A registered device with missing Wi-Fi supplicant settings may loop through registration instead of joining securely. Instead, correct WLC or supplicant settings and test first and subsequent secure reconnections. For the specific situation, a WLC uses the wrong ISE authorization profile and sends already-registered BYOD devices to the guest portal.
C:Disable server trust checks to connect an unknown WLAN controller. This action does not repair the identified failure.

Question 861
A mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL. Which administrator action is appropriate for this ISE access-control problem?
- Allow unrestricted production network access to fix one NSA download URL.
- Permit required supported NSA download and callback services during onboarding with restricted network scope.
- Assume a portal login automatically installs software without a client installer.
- Replace certificate provisioning with a one-time browser page refresh.
Explanation
Correct Answer
B:Verify the effect through client browser fetch, portal log, bootstrap ACL, NSA installer results and callback status. For the specific situation, a mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL.
Incorrect Answers
A:Denying the installer download path can halt a valid employee's certificate enrollment. This does not implement the required control for Network Setup Assistant download access.
C:Assume a portal login automatically installs software without a client installer. This alternative overlooks a required prerequisite or targets the wrong function. Native supplicant provisioning needs reachable package and validation services during restricted onboarding. The relevant evidence is client browser fetch, portal log, bootstrap ACL, NSA installer results and callback status. For the specific situation, a mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL.
D:Denying the installer download path can halt a valid employee's certificate enrollment. For the specific situation, a mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL.
Question 862
A mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL. Which collected records establish that the ISE decision actually took effect?
- Client browser fetch, portal log, bootstrap ACL, NSA installer results and callback status.
- 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

- Native supplicant provisioning needs reachable package and validation services during restricted onboarding.
- A policy display name alone is the complete source of enforcement state.
Explanation
Correct Answer
C:The supported implementation is to permit required supported NSA download and callback services during onboarding with restricted network scope. For the specific situation, a mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL.
Incorrect Answers
A:A successful switch port link signal always proves the device identity and policy were verified. This generalization is not valid for Network Setup Assistant download access.

Question 864
A mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL. An operator proposes the following incorrect shortcut: Allow unrestricted production network access to fix one NSA download URL. What specific security or operational failure should be anticipated?
- Denying the installer download path can halt a valid employee's certificate enrollment.
- 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 native supplicant provisioning needs reachable package and validation services during restricted onboarding. For the specific situation, a mobile BYOD portal says to install Network Setup Assistant but the download endpoint is blocked by an onboarding ACL.
Incorrect Answers
B:A justified least-privilege ACL caused every unrelated network authentication fault. This unrelated assertion does not explain the Network Setup Assistant download access problem.
