Cisco 300-715 Practice Test 78
Question 770
Device profiling records survive long after a switch replacement and mislead authorization. The observed failure is: Retaining old high-trust profiles may incorrectly admit replacement or spoofed devices. How should the administrator correct and verify this failure?
- The supported recovery is to grant permanent administrator permissions to avoid profile aging.
- The supported recovery is to treat yesterday's MAC profile as perpetual proof of the same physical hardware.
- The supported recovery is to disable all endpoint discovery because the inventory database contains entries.
- The supported recovery is to expire or correct stale attributes and reprofile from current evidence before applying access.
Explanation
Correct Answer
D:Recheck endpoint first and last seen, profiling attribute timestamps, purge rules and new session observations. For the specific situation, device profiling records survive long after a switch replacement and mislead authorization.
Incorrect Answers
A:Grant permanent administrator permissions to avoid profile aging. This action does not repair the identified failure. Retaining old high-trust profiles may incorrectly admit replacement or spoofed devices. Instead, expire or correct stale attributes and reprofile from current evidence before applying access. For the specific situation, device profiling records survive long after a switch replacement and mislead authorization.

Question 771
An endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities. Which configuration decision most directly satisfies the requirement?
- Import all endpoints into an unrestricted admin group to simplify CSV processing.
- Validate endpoint import format, unique MAC handling, group mapping and cleanup before enabling associated policy.
- Assume two differently formatted MAC strings always represent different devices.
- Delete all authentication traces after an import error.
Explanation
Correct Answer
B:Verify the effect through import logs, normalized MAC records, identity groups, duplicates and before-after access tests. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.
Incorrect Answers
A:This does not implement the required control for Endpoint import cleanup and duplicate MAC entries. Malformed or duplicated imports can break MAB matching or silently expand device privileges.
C:Assume two differently formatted MAC strings always represent different devices. This alternative overlooks a required prerequisite or targets the wrong function. Endpoint identity management relies on consistent identifiers and validated group membership. The relevant evidence is import logs, normalized MAC records, identity groups, duplicates and before-after access tests. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.
D:Malformed or duplicated imports can break MAB matching or silently expand device privileges. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.
Question 772
An endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities. What observations most directly test this network-access condition?
- Import logs, normalized MAC records, identity groups, duplicates and before-after access tests.
- A device hostname alone without the policy result or authenticated source.
- A current login screenshot from a completely unrelated ISE deployment.
- A browser theme label without a current authorization trace.
Explanation
Correct Answer
A:Endpoint identity management relies on consistent identifiers and validated group membership.
Incorrect Answers
B:This observation cannot verify Endpoint import cleanup and duplicate MAC entries. Check import logs, normalized MAC records, identity groups, duplicates and before-after access tests.
C:This observation cannot verify Endpoint import cleanup and duplicate MAC entries. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.
D:This observation cannot verify Endpoint import cleanup and duplicate MAC entries. Endpoint identity management relies on consistent identifiers and validated group membership.
Question 773
An endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities. 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.
- A policy display name alone is the complete source of enforcement state.
- Endpoint identity management relies on consistent identifiers and validated group membership.
Explanation
Correct Answer
D:The supported implementation is to validate endpoint import format, unique MAC handling, group mapping and cleanup before enabling associated policy. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.

Question 774
An endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities. An operator proposes the following incorrect shortcut: Import all endpoints into an unrestricted admin group to simplify CSV processing. Which negative consequence BEST explains the shortcut’s flaw?
- Malformed or duplicated imports can break MAB matching or silently expand device privileges.
- 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.
Explanation
Correct Answer
A:The shortcut is unsuitable because endpoint identity management relies on consistent identifiers and validated group membership. For the specific situation, an endpoint CSV import creates duplicate or incorrectly formatted MAC records and profiling rules choose inconsistent identities.
