Cisco 300-715 Practice Test 21
Question 200
A RADIUS EAP-TLS request fails when ISE cannot retrieve relevant certificate revocation status. The observed failure is: Skipping required revocation assessment can let compromised but unexpired credentials authenticate. Which controlled recovery BEST restores the intended state?
- The supported recovery is to repair responder path or revoke the compromised identity and retest a known certificate.
- The supported recovery is to use the switch management hostname as certificate serial revocation proof.
- The supported recovery is to assume a current certificate date guarantees it was never revoked.
- The supported recovery is to publish the CA private key to speed certificate validation.
Explanation
Correct Answer
A:Recheck oCSP or CRL response, certificate serial, chain trust, responder connectivity and RADIUS failure detail. For the specific situation, a RADIUS EAP-TLS request fails when ISE cannot retrieve relevant certificate revocation status.
Incorrect Answers
B:Use the switch management hostname as certificate serial revocation proof. This action does not repair the identified failure. Skipping required revocation assessment can let compromised but unexpired credentials authenticate. Instead, repair responder path or revoke the compromised identity and retest a known certificate. For the specific situation, a RADIUS EAP-TLS request fails when ISE cannot retrieve relevant certificate revocation status.
C:Assume a current certificate date guarantees it was never revoked. This action does not repair the identified failure. Skipping required revocation assessment can let compromised but unexpired credentials authenticate. Instead, repair responder path or revoke the compromised identity and retest a known certificate. For the specific situation, a RADIUS EAP-TLS request fails when ISE cannot retrieve relevant certificate revocation status.
D:Publish the CA private key to speed certificate validation. This action does not repair the identified failure. Skipping required revocation assessment can let compromised but unexpired credentials authenticate. Instead, repair responder path or revoke the compromised identity and retest a known certificate. For the specific situation, a RADIUS EAP-TLS request fails when ISE cannot retrieve relevant certificate revocation status.
Question 201
Employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source. What is the BEST supported ISE implementation or corrective action?
- Route every realm to the first available directory without checking account domain.
- Assume the wireless VLAN ID identifies the user's password database.
- Match identity source sequence selection to known realms, account types and explicit rule ordering.
- Ignore identity aliases and assert identical usernames always denote one person.
Explanation
Correct Answer
C:Verify the effect through user principal format, selected identity sequence, directory request and matched authentication rule. For the specific situation, employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source.
Incorrect Answers
A:An overly generic fallback sequence can reject valid accounts or confuse local and directory identities. This does not implement the required control for Identity source sequence realm routing.
B:Assume the wireless VLAN ID identifies the user's password database. This alternative overlooks a required prerequisite or targets the wrong function. Identity realms and lookup sequencing determine which credential store evaluates an access request. The relevant evidence is user principal format, selected identity sequence, directory request and matched authentication rule. For the specific situation, employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source.
D:An overly generic fallback sequence can reject valid accounts or confuse local and directory identities. For the specific situation, employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source.
Question 202
Employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source. Which evidence BEST verifies the intended operational outcome?

Incorrect Answers
B:This generalization is not valid for Identity source sequence realm routing. For the specific situation, employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source.
C:This generalization is not valid for Identity source sequence realm routing. Instead identity realms and lookup sequencing determine which credential store evaluates an access request.
D:This generalization is not valid for Identity source sequence realm routing. Verify the actual state using user principal format, selected identity sequence, directory request and matched authentication rule.
Question 204
Employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source. An operator proposes the following incorrect shortcut: Route every realm to the first available directory without checking account domain. What material risk or failure follows from that shortcut?
- A justified least-privilege ACL caused every unrelated network authentication fault.
- A correctly recorded TACACS command audit caused the preceding security violation.
- An overly generic fallback sequence can reject valid accounts or confuse local and directory identities.
- Reading the authentication event report caused the original network access outage.
Explanation
Correct Answer
C:The shortcut is unsuitable because identity realms and lookup sequencing determine which credential store evaluates an access request. For the specific situation, employees from two distinct AD forests enter the same SSID but only one realm matches the selected identity source.
