Cisco 300-715 Practice Test 42
Question 410
A mixed fleet has compatible devices and unsupported legacy devices but the allowed protocol list is overly broad. The observed failure is: Allowing a weak fallback can defeat a certificate-only access requirement. How should the administrator correct and verify this failure?
- The supported recovery is to disable client certificate validation when an EAP handshake fails.
- The supported recovery is to enable every legacy EAP method for every privileged workstation.
- The supported recovery is to assume selecting an SSID label enforces certificate-only authentication.
- The supported recovery is to constrain protocols and test compliant certificate clients and deliberate legacy exceptions.
Explanation
Correct Answer
D:This restores the intended operational behavior for Authentication protocol policy EAP method restrictions.
Incorrect Answers
A:Disable client certificate validation when an EAP handshake fails. This action does not repair the identified failure. Allowing a weak fallback can defeat a certificate-only access requirement. Instead, constrain protocols and test compliant certificate clients and deliberate legacy exceptions. For the specific situation, a mixed fleet has compatible devices and unsupported legacy devices but the allowed protocol list is overly broad.
B:Enable every legacy EAP method for every privileged workstation. This action does not repair the identified failure. Allowing a weak fallback can defeat a certificate-only access requirement. Instead, constrain protocols and test compliant certificate clients and deliberate legacy exceptions. For the specific situation, a mixed fleet has compatible devices and unsupported legacy devices but the allowed protocol list is overly broad.
C:Assume selecting an SSID label enforces certificate-only authentication. This action does not repair the identified failure.

Question 411
A maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint. Which configuration decision most directly satisfies the requirement?
- Create a permanent global bypass rule for a short maintenance activity.
- Use a policy description field as the sole exception matching condition.
- Define scoped policy exceptions using user, device, location and time conditions with a restricted authorization result.
- Grant full network access when only one remediation service is needed.
Explanation
Correct Answer
C:Verify the effect through matched exception condition, source device identity, access policy, expiry record and negative tests. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
Incorrect Answers
A:This does not implement the required control for Authorization profile service chaining and exception control. Overbroad exceptions can expand temporary privileged reach into ordinary production traffic.
B:Use a policy description field as the sole exception matching condition. This alternative overlooks a required prerequisite or targets the wrong function. Exceptions are deliberate authorization branches and should not override unrelated access rules. The relevant evidence is matched exception condition, source device identity, access policy, expiry record and negative tests. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
D:Overbroad exceptions can expand temporary privileged reach into ordinary production traffic. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
Question 412
A maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint. What observations most directly test this network-access condition?
- A device hostname alone without the policy result or authenticated source.
- Matched exception condition, source device identity, access policy, expiry record and negative tests.
- 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 Authorization profile service chaining and exception control for the described endpoint or network device. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
Incorrect Answers
A:This observation cannot verify Authorization profile service chaining and exception control. Exceptions are deliberate authorization branches and should not override unrelated access rules.
C:This observation cannot verify Authorization profile service chaining and exception control. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
D:This observation cannot verify Authorization profile service chaining and exception control. Check matched exception condition, source device identity, access policy, expiry record and negative tests.
Question 413
A maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint. What principle of ISE authentication and authorization explains this case?
- Exceptions are deliberate authorization branches and should not override unrelated access rules.
- 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.
- A policy display name alone is the complete source of enforcement state.
Explanation
Correct Answer
A:The supported implementation is to define scoped policy exceptions using user, device, location and time conditions with a restricted authorization result. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
Incorrect Answers
B:This generalization is not valid for Authorization profile service chaining and exception control. Instead exceptions are deliberate authorization branches and should not override unrelated access rules.
C:This generalization is not valid for Authorization profile service chaining and exception control. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
D:This generalization is not valid for Authorization profile service chaining and exception control. Verify the actual state using matched exception condition, source device identity, access policy, expiry record and negative tests.
Question 414
A maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint. An operator proposes the following incorrect shortcut: Create a permanent global bypass rule for a short maintenance activity. 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.
- Overbroad exceptions can expand temporary privileged reach into ordinary production traffic.
- Reading the authentication event report caused the original network access outage.
Explanation
Correct Answer
C:The shortcut is unsuitable because exceptions are deliberate authorization branches and should not override unrelated access rules. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
Incorrect Answers
A:This unrelated assertion does not explain the Authorization profile service chaining and exception control problem. The relevant risk is that overbroad exceptions can expand temporary privileged reach into ordinary production traffic.
B:This unrelated assertion does not explain the Authorization profile service chaining and exception control problem. For the specific situation, a maintenance device must temporarily access a service under a reviewed exception without being classified as a permanent employee endpoint.
D:This unrelated assertion does not explain the Authorization profile service chaining and exception control problem. Check matched exception condition, source device identity, access policy, expiry record and negative tests.
