Cisco 300-715 Practice Test 18
Question 170
An enterprise stores contractor credentials internally but fails to enforce account expiration and password policy. The observed failure is: An unmanaged always-active test account may retain network access long after its purpose expires. How should the administrator correct and verify this failure?
- The supported recovery is to scope internal accounts and expiry then test one active and one disabled credential.
- The supported recovery is to use a network device description field instead of checking the identity database.
- The supported recovery is to assume internal ISE user creation automatically creates an AD domain account.
- The supported recovery is to give every contractor a shared permanent password with no expiry.
Explanation
Correct Answer
A:This restores the intended operational behavior for Internal user identity store and password policy. For the specific situation, an enterprise stores contractor credentials internally but fails to enforce account expiration and password policy.
Incorrect Answers
B:Use a network device description field instead of checking the identity database. This action does not repair the identified failure. An unmanaged always-active test account may retain network access long after its purpose expires. Instead, scope internal accounts and expiry then test one active and one disabled credential. For the specific situation, an enterprise stores contractor credentials internally but fails to enforce account expiration and password policy.
C:Assume internal ISE user creation automatically creates an AD domain account. This action does not repair the identified failure. An unmanaged always-active test account may retain network access long after its purpose expires. Instead, scope internal accounts and expiry then test one active and one disabled credential. For the specific situation, an enterprise stores contractor credentials internally but fails to enforce account expiration and password policy.
D:Give every contractor a shared permanent password with no expiry. This action does not repair the identified failure. An unmanaged always-active test account may retain network access long after its purpose expires. Instead, scope internal accounts and expiry then test one active and one disabled credential. For the specific situation, an enterprise stores contractor credentials internally but fails to enforce account expiration and password policy.
Question 171
A managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account. Which configuration decision most directly satisfies the requirement?
- Accept every untrusted self-signed client certificate for privileged network access.
- Disable all certificate expiration checks instead of renewing device credentials.
- Treat the certificate friendly label as a complete trust-chain verification.
- Configure trusted issuer CA chains, certificate identity mapping and valid EAP-TLS policy for the endpoint type.
Explanation
Correct Answer
D:Verify the effect through certificate chain, EKU and validity, trusted CAs, identity extraction and RADIUS detailed steps. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
Incorrect Answers
A:This does not implement the required control for PKI certificate identity and EAP TLS mapping. Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices.
B:Disable all certificate expiration checks instead of renewing device credentials. This alternative overlooks a required prerequisite or targets the wrong function. Certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate. The relevant evidence is certificate chain, EKU and validity, trusted CAs, identity extraction and RADIUS detailed steps. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
C:Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
Question 172
A managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account. What observations most directly test this network-access condition?
- A device hostname alone without the policy result or authenticated source.
- Certificate chain, EKU and validity, trusted CAs, identity extraction and RADIUS detailed steps.
- A current login screenshot from a completely unrelated ISE deployment.
- A browser theme label without a current authorization trace.
Explanation
Correct Answer
B:These observations directly establish the result of PKI certificate identity and EAP TLS mapping for the described endpoint or network device. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
Incorrect Answers
A:This observation cannot verify PKI certificate identity and EAP TLS mapping. Certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate.
C:This observation cannot verify PKI certificate identity and EAP TLS mapping. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
D:This observation cannot verify PKI certificate identity and EAP TLS mapping. Check certificate chain, EKU and validity, trusted CAs, identity extraction and RADIUS detailed steps.
Question 173
A managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account. What principle of ISE authentication and authorization explains this case?
- 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.
- Certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate.
- A policy display name alone is the complete source of enforcement state.
Explanation
Correct Answer
C:The supported implementation is to configure trusted issuer CA chains, certificate identity mapping and valid EAP-TLS policy for the endpoint type. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
Incorrect Answers
A:This generalization is not valid for PKI certificate identity and EAP TLS mapping. Instead certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate.
B:This generalization is not valid for PKI certificate identity and EAP TLS mapping. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
D:This generalization is not valid for PKI certificate identity and EAP TLS mapping. Verify the actual state using certificate chain, EKU and validity, trusted CAs, identity extraction and RADIUS detailed steps.
Question 174
A managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account. An operator proposes the following incorrect shortcut: Accept every untrusted self-signed client certificate for privileged network access. Which negative consequence BEST explains the shortcut’s flaw?
- 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.
- Trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices.
Explanation
Correct Answer
D:The shortcut is unsuitable because certificate-based authentication requires certificate trust and correct mapping, not only possession of any certificate. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
Incorrect Answers
A:This unrelated assertion does not explain the PKI certificate identity and EAP TLS mapping problem. The relevant risk is that trusting unqualified issuers or failing to map identity can deny valid clients or admit inappropriate devices.
B:This unrelated assertion does not explain the PKI certificate identity and EAP TLS mapping problem. For the specific situation, a managed laptop has a valid machine certificate but ISE cannot map its subject identity to the expected account.
