Cisco 300-715 Practice Test 45
Question 440
A network upgrade moves captive authentication from controller-local forms to an ISE portal without updating policy. The observed failure is: Mixing local form handling and external redirect policy can prevent visitors from completing the login. Which controlled recovery BEST restores the intended state?
- The supported recovery is to align controller captive portal settings and ISE policy with one supported authentication model.
- The supported recovery is to use guest email delivery settings to replace WLC web-auth configuration.
- The supported recovery is to assume every controller automatically treats a local web portal as an ISE central portal.
- The supported recovery is to enable both conflicting redirects without testing priority.
Explanation
Correct Answer
A:Recheck wLC portal hosting mode, chosen redirect URL, RADIUS attributes, logon result and policy session. For the specific situation, a network upgrade moves captive authentication from controller-local forms to an ISE portal without updating policy.
Incorrect Answers
B:Use guest email delivery settings to replace WLC web-auth configuration. This action does not repair the identified failure. Mixing local form handling and external redirect policy can prevent visitors from completing the login. Instead, align controller captive portal settings and ISE policy with one supported authentication model. For the specific situation, a network upgrade moves captive authentication from controller-local forms to an ISE portal without updating policy.

Question 441
Guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN. What is the BEST supported ISE implementation or corrective action?
- Instruct all visitors to ignore captive portal TLS warnings permanently.
- Install a valid trusted portal certificate with matching FQDN and correct DNS and redirect address.
- Assume any certificate from a trusted CA is valid for every DNS hostname.
- Disable HTTPS verification instead of correcting the redirected name.
Explanation
Correct Answer
B:Verify the effect through portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access. HTTPS portal trust requires a certificate valid for the hostname users actually visit.
Incorrect Answers
A:This does not implement the required control for Captive portal certificate hostname and client trust. Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login.
C:Assume any certificate from a trusted CA is valid for every DNS hostname. This alternative overlooks a required prerequisite or targets the wrong function. HTTPS portal trust requires a certificate valid for the hostname users actually visit. The relevant evidence is portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access. For the specific situation, guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN.
D:Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login. Instead the intended policy action is install a valid trusted portal certificate with matching FQDN and correct DNS and redirect address.
Question 442
Guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN. Which evidence BEST verifies the intended operational outcome?
- Portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access.
- 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:These observations directly establish the result of Captive portal certificate hostname and client trust for the described endpoint or network device. HTTPS portal trust requires a certificate valid for the hostname users actually visit.
Incorrect Answers
B:This observation cannot verify Captive portal certificate hostname and client trust. HTTPS portal trust requires a certificate valid for the hostname users actually visit.
C:This observation cannot verify Captive portal certificate hostname and client trust. Check portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access.
D:This observation cannot verify Captive portal certificate hostname and client trust. A browser theme label without a current authorization trace.
Question 443
Guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN. Which technical principle BEST explains the required decision?
- HTTPS portal trust requires a certificate valid for the hostname users actually visit.
- 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.
Explanation
Correct Answer
A:The supported implementation is to install a valid trusted portal certificate with matching FQDN and correct DNS and redirect address. For the specific situation, guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN.
Incorrect Answers
B:A successful switch port link signal always proves the device identity and policy were verified. This generalization is not valid for Captive portal certificate hostname and client trust. Instead hTTPS portal trust requires a certificate valid for the hostname users actually visit. Verify the actual state using portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access. For the specific situation, guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN.

Question 444
Guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN. An operator proposes the following incorrect shortcut: Instruct all visitors to ignore captive portal TLS warnings permanently. What material risk or failure follows from that shortcut?
- A justified least-privilege ACL caused every unrelated network authentication fault.
- Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login.
- 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
B:The shortcut is unsuitable because hTTPS portal trust requires a certificate valid for the hostname users actually visit. For the specific situation, guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN.
Incorrect Answers
A:This unrelated assertion does not explain the Captive portal certificate hostname and client trust problem. The relevant risk is that ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login.
C:This unrelated assertion does not explain the Captive portal certificate hostname and client trust problem. Check portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access.
D:This unrelated assertion does not explain the Captive portal certificate hostname and client trust problem. For the specific situation, guest devices report a browser certificate-name warning when redirected to a captive portal on an unexpected FQDN.
Question 445

Question 448
The portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname. What principle of ISE authentication and authorization explains this case?

- The governing principle is that every RADIUS Access-Accept grants unrestricted access to all applications.
- The governing principle is that hTTPS portal trust requires a certificate valid for the hostname users actually visit.

Question 450
The portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname. The observed failure is: Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login. How should the administrator correct and verify this failure?
