Question 180
An EAP-TLS client certificate chains to an untrusted issuing CA and ISE rejects the request. The observed failure is: Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices. Which remediation resolves the underlying fault while maintaining policy?
- The supported recovery is to repair issuer trust or certificate identity rules and validate a supported client certificate.
- The supported recovery is to treat the certificate friendly label as a complete trust-chain verification.
- The supported recovery is to accept every untrusted self-signed client certificate for privileged network access.
- The supported recovery is to disable all certificate expiration checks instead of renewing device credentials.
Explanation
Correct Answer
A:Certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate. For the specific situation, an EAP-TLS client certificate chains to an untrusted issuing CA and ISE rejects the request.
Incorrect Answers
B:Treat the certificate friendly label as a complete trust-chain verification. This action does not repair the identified failure. Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices. Instead, repair issuer trust or certificate identity rules and validate a supported client certificate. For the specific situation, an EAP-TLS client certificate chains to an untrusted issuing CA and ISE rejects the request.
C:Accept every untrusted self-signed client certificate for privileged network access. This action does not repair the identified failure. Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices. Instead, repair issuer trust or certificate identity rules and validate a supported client certificate. For the specific situation, an EAP-TLS client certificate chains to an untrusted issuing CA and ISE rejects the request.
D:Disable all certificate expiration checks instead of renewing device credentials. This action does not repair the identified failure. Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices. Instead, repair issuer trust or certificate identity rules and validate a supported client certificate. For the specific situation, an EAP-TLS client certificate chains to an untrusted issuing CA and ISE rejects the request.
Question 181
An administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded. Which administrator action is appropriate for this ISE access-control problem?
- Treat a username and password as proof of a separate MFA factor.
- Configure a supported MFA integration or identity source and test its challenge and failure behavior for the intended policy.
- Disable all authentication when the challenge page renders incorrectly.
- Assume the wireless SSID text itself activates multifactor verification.
Explanation
Correct Answer
B:Verify the effect through mFA provider authentication result, ISE access logs, client challenge outcome and tested timeout. For the specific situation, an administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded.
Incorrect Answers
A:This does not implement the required control for Multifactor authentication integration boundary. Fail-open behavior under provider outage can negate a network access MFA requirement.
C:Disable all authentication when the challenge page renders incorrectly. This alternative overlooks a required prerequisite or targets the wrong function. A first-factor directory lookup does not inherently prove the second factor was satisfied. The relevant evidence is mFA provider authentication result, ISE access logs, client challenge outcome and tested timeout. For the specific situation, an administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded.
D:Fail-open behavior under provider outage can negate a network access MFA requirement. For the specific situation, an administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded.
Question 182
An administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded. Which collected records establish that the ISE decision actually took effect?
- A switch interface description without any live AAA request or response.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- A current login screenshot from a completely unrelated ISE deployment.
- MFA provider authentication result, ISE access logs, client challenge outcome and tested timeout.

Question 183
An administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded. Which statement about the relevant technology is correct?

- A successful switch port link signal always proves the device identity and policy were verified.
- Every RADIUS Access-Accept grants unrestricted access to all applications.
Explanation

C:This generalization is not valid for Multifactor authentication integration boundary. For the specific situation, an administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded.
D:This generalization is not valid for Multifactor authentication integration boundary. Verify the actual state using mFA provider authentication result, ISE access logs, client challenge outcome and tested timeout.
Question 184
An administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded. An operator proposes the following incorrect shortcut: Treat a username and password as proof of a separate MFA factor. What specific security or operational failure should be anticipated?
- Reading the authentication event report caused the original network access outage.
- Fail-open behavior under provider outage can negate a network access MFA requirement.
- The only result is an unrelated portal background color change.
- Accurate device accounting automatically created every earlier failed EAP exchange.
Explanation
Correct Answer
B:The shortcut is unsuitable because a first-factor directory lookup does not inherently prove the second factor was satisfied. For the specific situation, an administrator assumes ISE automatically sends a second-factor challenge simply because AD authentication succeeded.
