Cisco 300-715 Practice Test 89
Question 880
An Android model is not compatible with a selected native supplicant helper and the team assumes all versions behave identically. The observed failure is: Applying one installer path to every phone and laptop can strand devices before strong authentication. Which controlled recovery BEST restores the intended state?
- The supported recovery is to treat a MAC vendor prefix as an operating system version test.
- The supported recovery is to use the appropriate approved platform workflow and verify installed EAP settings on each OS.
- The supported recovery is to assume all mobile platforms accept a desktop installer package.
- The supported recovery is to bypass all device certificate validation because one Android enrollment failed.
Explanation
Correct Answer
B:Recheck device OS version, supported provisioning method, NSA response, installed profile and final EAP result. For the specific situation, an Android model is not compatible with a selected native supplicant helper and the team assumes all versions behave identically.
Incorrect Answers
A:Treat a MAC vendor prefix as an operating system version test. This action does not repair the identified failure. Applying one installer path to every phone and laptop can strand devices before strong authentication. Instead, use the appropriate approved platform workflow and verify installed EAP settings on each OS. For the specific situation, an Android model is not compatible with a selected native supplicant helper and the team assumes all versions behave identically.

Question 881
A personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping. What is the BEST supported ISE implementation or corrective action?
- Configure certificate templates and identity mapping that bind the device and authorized employee without using shared identities.
- Assign every personal device the same shared certificate username.
- Use only the certificate's friendly local nickname as identity evidence.
- Ignore user-to-device association because TLS is encrypted.
Explanation
Correct Answer
A:Verify the effect through issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
Incorrect Answers
B:This does not implement the required control for BYOD certificate subject identity and SAN mapping. Duplicate or improperly mapped certificate subjects can assign access to an unintended account.
C:Use only the certificate's friendly local nickname as identity evidence. This alternative overlooks a required prerequisite or targets the wrong function. BYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions. The relevant evidence is issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
D:Duplicate or improperly mapped certificate subjects can assign access to an unintended account. Instead the intended policy action is configure certificate templates and identity mapping that bind the device and authorized employee without using shared identities.
Question 882
A personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping. Which evidence BEST verifies the intended operational outcome?
- Issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group.
- A successful ICMP echo that does not test the required identity-service workflow.
- A browser theme label without a current authorization trace.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
Explanation
Correct Answer
A:These observations directly establish the result of BYOD certificate subject identity and SAN mapping for the described endpoint or network device. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
Incorrect Answers
B:A successful ICMP echo that does not test the required identity-service workflow. This observation cannot verify BYOD certificate subject identity and SAN mapping. Check issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group. BYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
C:A browser theme label without a current authorization trace. This observation cannot verify BYOD certificate subject identity and SAN mapping. Check issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group. BYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
D:An old diagram with no RADIUS, TACACS+ or endpoint-session evidence. This observation cannot verify BYOD certificate subject identity and SAN mapping. Check issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group. BYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
Question 883
A personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping. Which technical principle BEST explains the required decision?
- All Cisco ISE administration and policy personas perform exactly the same service.
- A captive portal page automatically changes network authorization on every active NAD session without signaling.
- A MAC address is a cryptographic proof of endpoint device ownership.
- BYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions.
Explanation
Correct Answer
D:The supported implementation is to configure certificate templates and identity mapping that bind the device and authorized employee without using shared identities. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
Incorrect Answers
A:This generalization is not valid for BYOD certificate subject identity and SAN mapping. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
B:This generalization is not valid for BYOD certificate subject identity and SAN mapping. Instead bYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions.
C:This generalization is not valid for BYOD certificate subject identity and SAN mapping. Verify the actual state using issued certificate subject and SAN, mapped user, endpoint record, authentication detail and authorization group.
Question 884
A personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping. An operator proposes the following incorrect shortcut: Assign every personal device the same shared certificate username. What material risk or failure follows from that shortcut?
- Accurate device accounting automatically created every earlier failed EAP exchange.
- Inspecting a correct endpoint certificate generated the original directory outage.
- Duplicate or improperly mapped certificate subjects can assign access to an unintended account.
- A justified least-privilege ACL caused every unrelated network authentication fault.
Explanation
Correct Answer
C:The shortcut is unsuitable because bYOD certificate identity design should support accurate ownership attribution and appropriate policy conditions. For the specific situation, a personal device authenticates but ISE links its certificate to another employee due to incorrect subject mapping.
Incorrect Answers
A:This unrelated assertion does not explain the BYOD certificate subject identity and SAN mapping problem. The relevant risk is that duplicate or improperly mapped certificate subjects can assign access to an unintended account.
