Cisco 300-715 Practice Test 120
Question 1190
A network team needs command logs that connect a human operator with a target switch and timestamp. The observed failure is: Without command records, a successful AAA login cannot demonstrate who performed a particular change. What recovery action restores supported network-access behavior?
- The supported recovery is to use the router hostname alone as the complete human audit identity.
- The supported recovery is to assume a saved login event lists every command later executed.
- The supported recovery is to repair device and ISE accounting integration and generate one controlled show and configuration event.
- The supported recovery is to delete all network device accounting to reduce report volume.
Explanation
Correct Answer
C:Command accounting establishes a reviewable trail of device administrator actions when properly configured. For the specific situation, a network team needs command logs that connect a human operator with a target switch and timestamp.
Incorrect Answers
A:Use the router hostname alone as the complete human audit identity. This action does not repair the identified failure. Without command records, a successful AAA login cannot demonstrate who performed a particular change. Instead, repair device and ISE accounting integration and generate one controlled show and configuration event. For the specific situation, a network team needs command logs that connect a human operator with a target switch and timestamp.
B:Assume a saved login event lists every command later executed. This action does not repair the identified failure.

Question 1191
An access switch has two TACACS PSNs but its server group still targets only the disabled primary. What action addresses this authenticated network-access scenario?
- Use a shared permanent unlogged local admin account for routine operations.
- Assume creating a second PSN automatically updates all switch TACACS destinations.
- Configure redundant TACACS servers and a documented least-privilege emergency fallback for true AAA unavailability.
- Disable TACACS permanently because one primary node failed during maintenance.
Explanation
Correct Answer
C:This is the targeted action for TACACS primary secondary node failover and local emergency access. For the specific situation, an access switch has two TACACS PSNs but its server group still targets only the disabled primary.
Incorrect Answers
A:This does not implement the required control for TACACS primary secondary node failover and local emergency access. For the specific situation, an access switch has two TACACS PSNs but its server group still targets only the disabled primary.
B:Assume creating a second PSN automatically updates all switch TACACS destinations. This alternative overlooks a required prerequisite or targets the wrong function. Device-admin resiliency depends on reachable AAA endpoints plus carefully bounded emergency operations. The relevant evidence is tACACS server priority, TCP reachability, timeout, fallback activation and emergency-account audit. For the specific situation, an access switch has two TACACS PSNs but its server group still targets only the disabled primary.
D:A broad unconditional local fallback may undermine centralized command authorization even when ISE is healthy. For the specific situation, an access switch has two TACACS PSNs but its server group still targets only the disabled primary.
Question 1192
An access switch has two TACACS PSNs but its server group still targets only the disabled primary. What verification should the engineer use before declaring success?
- A device hostname alone without the policy result or authenticated source.
- TACACS server priority, TCP reachability, timeout, fallback activation and emergency-account audit.
- A current login screenshot from a completely unrelated ISE deployment.
- A browser theme label without a current authorization trace.

Question 1193
An access switch has two TACACS PSNs but its server group still targets only the disabled primary. Which underlying service behavior supports the proposed solution?
- Device-admin resiliency depends on reachable AAA endpoints plus carefully bounded emergency operations.
- 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.

Question 1194
An access switch has two TACACS PSNs but its server group still targets only the disabled primary. An operator proposes the following incorrect shortcut: Use a shared permanent unlogged local admin account for routine operations. Why does that proposed shortcut not satisfy the requirement?
- A justified least-privilege ACL caused every unrelated network authentication fault.
- A broad unconditional local fallback may undermine centralized command authorization even when ISE is healthy.
- 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
B:The shortcut is unsuitable because device-admin resiliency depends on reachable AAA endpoints plus carefully bounded emergency operations. For the specific situation, an access switch has two TACACS PSNs but its server group still targets only the disabled primary.
