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?

  1. The supported recovery is to disable HTTPS verification instead of correcting the redirected name.
  2. The supported recovery is to fix certificate binding and portal FQDN then test TLS validation on representative devices.
  3. The supported recovery is to instruct all visitors to ignore captive portal TLS warnings permanently.
  4. The supported recovery is to assume any certificate from a trusted CA is valid for every DNS hostname.

Explanation

Correct Answer

B:

Recheck portal URL hostname, certificate SAN and issuer, DNS resolution, browser TLS warning and portal access. For the specific situation, the portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname.

Incorrect Answers

A:

Disable HTTPS verification instead of correcting the redirected name. This action does not repair the identified failure. Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login. Instead, fix certificate binding and portal FQDN then test TLS validation on representative devices. For the specific situation, the portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname.

C:

Instruct all visitors to ignore captive portal TLS warnings permanently. This action does not repair the identified failure. Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login. Instead, fix certificate binding and portal FQDN then test TLS validation on representative devices. For the specific situation, the portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname.

D:

Assume any certificate from a trusted CA is valid for every DNS hostname. This action does not repair the identified failure. Ignoring a portal hostname mismatch trains guests to bypass certificate warnings or blocks login. Instead, fix certificate binding and portal FQDN then test TLS validation on representative devices. For the specific situation, the portal uses a trusted CA certificate but its SAN does not contain the sponsor-access hostname.

Question 451

A visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login. Which configuration decision most directly satisfies the requirement?

  1. Permit all internal networks to every unauthenticated client as the bootstrap policy.
  2. Block the captive portal listener and rely on the browser cache.
  3. Permit only the supported pre-auth DHCP, DNS and portal flows while keeping corporate services restricted.
  4. Use an endpoint MAC display name as the substitute for DNS resolution.

Explanation

Correct Answer

C:

Verify the effect through prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

Incorrect Answers

A:

A deny-all ACL can prevent the client from resolving or reaching its own login page. This does not implement the required control for Web-auth redirect ACL prelogin reachability.

B:

Block the captive portal listener and rely on the browser cache. This alternative overlooks a required prerequisite or targets the wrong function. A redirect ACL must allow necessary bootstrap connectivity even before full network authorization. The relevant evidence is prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

D:

A deny-all ACL can prevent the client from resolving or reaching its own login page. Instead the intended policy action is permit only the supported pre-auth DHCP, DNS and portal flows while keeping corporate services restricted.

Question 452

A visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login. What observations most directly test this network-access condition?

  1. A switch interface description without any live AAA request or response.
  2. An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
  3. A current login screenshot from a completely unrelated ISE deployment.
  4. Prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log.

Explanation

Correct Answer

D:

These observations directly establish the result of Web-auth redirect ACL prelogin reachability for the described endpoint or network device. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

Incorrect Answers

A:

This observation cannot verify Web-auth redirect ACL prelogin reachability. A redirect ACL must allow necessary bootstrap connectivity even before full network authorization.

B:

This observation cannot verify Web-auth redirect ACL prelogin reachability. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

C:

This observation cannot verify Web-auth redirect ACL prelogin reachability. Check prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log.

Question 453

A visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login. What principle of ISE authentication and authorization explains this case?

  1. A redirect ACL must allow necessary bootstrap connectivity even before full network authorization.
  2. A captive portal page automatically changes network authorization on every active NAD session without signaling.
  3. A successful switch port link signal always proves the device identity and policy were verified.
  4. Every RADIUS Access-Accept grants unrestricted access to all applications.

Explanation

Correct Answer

A:

The supported implementation is to permit only the supported pre-auth DHCP, DNS and portal flows while keeping corporate services restricted. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

Incorrect Answers

B:

This generalization is not valid for Web-auth redirect ACL prelogin reachability. Instead a redirect ACL must allow necessary bootstrap connectivity even before full network authorization.

C:

This generalization is not valid for Web-auth redirect ACL prelogin reachability. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

D:

This generalization is not valid for Web-auth redirect ACL prelogin reachability. Verify the actual state using prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log.

Question 454

A visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login. An operator proposes the following incorrect shortcut: Permit all internal networks to every unauthenticated client as the bootstrap policy. Which negative consequence BEST explains the shortcut’s flaw?

  1. Reading the authentication event report caused the original network access outage.
  2. The only result is an unrelated portal background color change.
  3. A deny-all ACL can prevent the client from resolving or reaching its own login page.
  4. Accurate device accounting automatically created every earlier failed EAP exchange.

Explanation

Correct Answer

C:

The shortcut is unsuitable because a redirect ACL must allow necessary bootstrap connectivity even before full network authorization. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

Incorrect Answers

A:

This unrelated assertion does not explain the Web-auth redirect ACL prelogin reachability problem. The relevant risk is that a deny-all ACL can prevent the client from resolving or reaching its own login page.

B:

This unrelated assertion does not explain the Web-auth redirect ACL prelogin reachability problem. For the specific situation, a visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login.

D:

This unrelated assertion does not explain the Web-auth redirect ACL prelogin reachability problem. Check prelogin dACL entries, DNS request and reply, HTTPS reachability, packet trace and portal log.

Question 455

A visitor receives a redirect but cannot resolve the portal name because DNS is blocked before login. The observed failure is: A deny-all ACL can prevent the client from resolving or reaching its own login page. How should the administrator correct and verify this failure?

  1. Block the captive portal listener and rely on the browser cache.
  2. Add minimum required bootstrap exceptions then retest portal accessibility and forbidden internal traffic.
  3. Use an endpoint MAC display name as the substitute for DNS resolution.
  4. Permit all internal networks to every unauthenticated client as the bootstrap policy.
