300-615 Exam Dumps - Cisco CCNP Data Center Questions and Answers

The selected option, event statement, is correct for the automation path described. Cisco NX-OS requires precision in EEM applets, scheduler jobs, Guest Shell operations, and REST/NX-API syntax. The affected element is EEM; therefore, the fix must be applied to the component that actually executes the action. For EEM, that means a valid event detector and explicit actions, with event-default when the matched CLI command should continue. For Guest Shell and Bash, DNS, proxy, resource allocation, and reboot behavior are local to the Linux container. For REST calls, the class name, method, authentication, and XML/JSON structure must match the APIC or NX-OS object model. The distractors usually change the switch globally or alter an unrelated command. Cisco DCIT automation troubleshooting confirms the fix by checking the returned error, then rerunning the exact job, script, or API operation in the same context. The final check is to document the before-and-after state so the remediation is tied to a repeatable Cisco troubleshooting symptom rather than an assumed fix.

Cisco troubleshooting logic supports Modify the subnet mask of Loopback 254 to ' 30 on Spine2 as the required fix. In this question the symptoms point to VXLAN, and the defect is best handled by correcting the exact control-plane or consistency condition. Nexus platforms can show interfaces or peers as configured while still refusing to forward traffic if a vPC Type-1 parameter, VLAN allowance, MTU, HSRP version, EVPN route, or routing attribute is wrong. Cisco methodology is to avoid broad resets unless the state machine is stuck; instead, correct the mismatched parameter and verify that the resulting operational state becomes stable. The other choices do not remove the root cause, or they modify a setting that is not used by the failing protocol exchange. After the change, the engineer should review the peer status, route or MAC table, and counters for drops or inconsistency messages. That sequence proves that the network fabric is fixed, not merely restarted.

Cisco troubleshooting logic supports Change channel-group ID from 9 to 2 on N9K-3 as the required fix. In this question the symptoms point to vPC, and the defect is best handled by correcting the exact control-plane or consistency condition.

Add the DNS server and suffix; Configure domain-name and nameserver under the management VRF resolves the problem because the symptom is specific to the automation subsystem handling Guest Shell, Cisco Nexus, Nexus 9000, Cisco Nexus 9000. Nexus automation failures are frequently caused by a missing EEM event statement, absent event-default action, invalid REST path, incorrect JSON or XML syntax, Guest Shell DNS/resource settings, or a scheduler feature that is not enabled. The selected answer corrects that execution prerequisite. The wrong options may make sense for normal switch forwarding, but they do not repair the automation control path. Cisco documentation treats Guest Shell as a separate Linux environment and EEM as a policy engine that can intercept CLI events; both must be validated from their own operational state. A proper verification is to confirm the policy is registered, run the job or API call again, review the response or syslog output, and ensure that normal CLI behavior is preserved after the automation fires.

Replace the self-signed certificate that is installed on the Cisco IMC with a server certificate that is signed from the client corporate certificate is correct because the failure is tied to the UCS managed state of UCS, Cisco IMC, certificate. In Cisco UCS, policies are not advisory; they are the source from which fabric interconnects program adapters, boot targets, server identity, firmware, and external integrations. A mismatch between the policy and the actual hardware or upstream storage/network state can cause boot, discovery, KVM, firmware, or connectivity failures. The selected action addresses the object that UCS Manager uses to build the final operational configuration. The distractors either solve a different fault domain or bypass the policy model. A disciplined DCIT validation sequence is to check the fault code, the FSM history, the equipment inventory, the service profile association, and the relevant adapter or boot table. If those states are correct after the change, the UCS component should return to operable service without unnecessary reconfiguration.

Disable the inband-telemetry feature resolves the problem because the symptom is specific to the automation subsystem handling inband-telemetry, packet postcards, Cisco Nexus, Nexus 9000, Cisco Nexus 9000. Nexus automation failures are frequently caused by a missing EEM event statement, absent event-default action, invalid REST path, incorrect JSON or XML syntax, Guest Shell DNS/resource settings, or a scheduler feature that is not enabled. The selected answer corrects that execution prerequisite. The wrong options may make sense for normal switch forwarding, but they do not repair the automation control path.
