300-615 Exam Dumps - Troubleshooting Cisco Data Center Infrastructure (300-615 DCIT) v1.1

The correct remediation is Create a route map that sets the IPv6 next hop. In Cisco data center troubleshooting, the first priority is to isolate whether the failure is caused by the underlay, overlay control plane, first-hop gateway behavior, or a consistency parameter. This item is centered on EVPN, BGP, so the selected action targets the condition that prevents normal forwarding rather than masking the symptom. Cisco Nexus and ACI guidance treats vPC, VXLAN EVPN, OTV, OSPF, BGP, HSRP, and LACP issues as state-dependent technologies: a neighbor, peer, VLAN, VNI, multicast group, timer, MTU, or policy mismatch can leave the protocol partially operational while traffic is still dropped. The rejected alternatives either change unrelated attributes, introduce a new inconsistency, or affect only a secondary behavior. The operational check after applying the fix should be to confirm adjacency or peer state, validate the relevant route/MAC/endpoint table, and test traffic in the affected VLAN or VRF. This aligns with Cisco DCIT network troubleshooting methodology for isolating control-plane state before changing data-plane policy.

Insert an SD card into SLOT-2 is correct because the failure is tied to the UCS managed state of UCS. 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.

The correct remediation is Add VLAN 88 using switchport trunk allowed VLAN add 88 on VTEP1. In Cisco data center troubleshooting, the first priority is to isolate whether the failure is caused by the underlay, overlay control plane, first-hop gateway behavior, or a consistency parameter. This item is centered on VXLAN, Cisco Nexus, Nexus 9000, Cisco Nexus 9000, so the selected action targets the condition that prevents normal forwarding rather than masking the symptom. Cisco Nexus and ACI guidance treats vPC, VXLAN EVPN, OTV, OSPF, BGP, HSRP, and LACP issues as state-dependent technologies: a neighbor, peer, VLAN, VNI, multicast group, timer, MTU, or policy mismatch can leave the protocol partially operational while traffic is still dropped.

The correct remediation is Configure a unicast access list to allow the negotiation between N9K-1 and N9K-2. In Cisco data center troubleshooting, the first priority is to isolate whether the failure is caused by the underlay, overlay control plane, first-hop gateway behavior, or a consistency parameter. This item is centered on OSPF, Cisco Nexus, so the selected action targets the condition that prevents normal forwarding rather than masking the symptom.

Cisco troubleshooting logic supports the drag-and-drop mapping shown in the answer key as the required fix. In this question the symptoms point to DRAG, DROP, Drag, Not, 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.

Migrate all virtual machines in the EPG-1 to different port groups is the valid corrective action because the failure described is a protocol or fabric state problem, not a generic connectivity issue. For EPG, VMM, Cisco troubleshooting expects the engineer to compare both endpoints of the relationship: vPC peers must agree on consistency parameters, HSRP peers must exchange hellos in the same VLAN and version context, OSPF/BGP peers must match the attributes required for stable adjacency, and VXLAN EVPN must advertise the correct host or prefix information. The selected option restores that required state. The other options either operate on the wrong layer, change a value that is not used to form the relationship, or would make the peer relationship less deterministic. A clean validation is to inspect the control-plane table first, then verify the forwarding table, and finally test end-to-end traffic. This is the Cisco-preferred approach because it avoids random changes and confirms that the fabric is forwarding based on correct protocol state.

Set the community to 65000:65000 under the route map is the valid corrective action because the failure described is a protocol or fabric state problem, not a generic connectivity issue. For BGP, Cisco troubleshooting expects the engineer to compare both endpoints of the relationship: vPC peers must agree on consistency parameters, HSRP peers must exchange hellos in the same VLAN and version context, OSPF/BGP peers must match the attributes required for stable adjacency, and VXLAN EVPN must advertise the correct host or prefix information.

https://172.16.10.1/api/node/mo/uni/tn-Test1.xml? rsp-subtree=full & rsp-prop-include=config-only resolves the problem because the symptom is specific to the automation subsystem handling REST API, Cisco Nexus. 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.
