The selected resolution is Change the switch port mode to an E port; Issue the no shutdown command on interface fct ' 24 because the failure is in the Fibre Channel/FCoE control path around MDS, UCS. Cisco MDS and Nexus platforms separate configuration from operational state: a VSAN, zone, vFC binding, device alias, or port-security entry can exist in configuration but still fail if it is not active, correctly merged, or allowed on the link. The correct option addresses the fabric condition that prevents communication. The incorrect options are technically adjacent but would not repair the specific dependency; for example, changing unrelated databases or resetting ports without correcting policy leaves the same failure to recur. Cisco SAN troubleshooting therefore starts with port role and VSAN checks, then confirms fabric services such as fcdomain, FSPF, zoning, fabric binding, and name-server information. The expected validation is that the port becomes operational, the initiator and target appear in the appropriate databases, and permitted zone members can communicate.

Include a new VLAN on the appliance port is the correct fix under Cisco SAN troubleshooting practice. The issue described involves UCS, vNIC, vHBA, where the operating state depends on the correct combination of port type, VSAN, fabric service, and access-control database. MDS and Nexus SAN features do not infer missing policy: if the active zoneset, fabric-binding database, fcdomain, NPIV setting, or FCoE/LLDP negotiation is wrong, the link may come up physically but the initiator will not reach the target. The selected answer corrects the missing or mismatched element. The remaining choices either act at the wrong layer, change a non-causal parameter, or provide only a temporary reset. After applying the fix, a proper Cisco validation path is to review show interface, show flogi database, show fcns database, show zoneset active, and any isolation or merge-failure logs. That confirms the storage network is operationally consistent.

The selected resolution is Assign fc1/3 as NP port on MDS-A and F port on fc1/4 N9K-1 because the failure is in the Fibre Channel/FCoE control path around MDS, FLOGI, FCID, NPV. Cisco MDS and Nexus platforms separate configuration from operational state: a VSAN, zone, vFC binding, device alias, or port-security entry can exist in configuration but still fail if it is not active, correctly merged, or allowed on the link. The correct option addresses the fabric condition that prevents communication. The incorrect options are technically adjacent but would not repair the specific dependency; for example, changing unrelated databases or resetting ports without correcting policy leaves the same failure to recur.

Modify the URI to 192.15.132.101/api/node/class/fvTenant.json resolves the problem because the symptom is specific to the automation subsystem handling When, GET, Tenant, Request. 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.

action 2.0 event-default is the required fix because the automation failure is caused by execution context, syntax, or resource state around EEM. On Cisco Nexus switches, automation is not a single feature; EEM policies, CLI actions, Guest Shell Linux commands, REST payloads, and scheduled jobs are evaluated by different subsystems. A script can fail even while the switch itself has connectivity or the command works interactively. The selected answer supplies the missing requirement, such as the correct event/action, DNS or resource setting, API URI, payload format, feature enablement, or reboot needed for a Guest Shell change to take effect. The other choices address adjacent features but do not satisfy the failing subsystem. After applying the fix, the engineer should verify the policy registration, job result, API response code, or Guest Shell runtime state and confirm that the intended command is no longer blocked or silently ignored.

The selected answer, Load an uncorrupt kickstart image; Load the correct version of the boot image, follows Cisco UCS operational logic. UCS Manager is policy-driven, so troubleshooting must determine whether the problem is caused by hardware discovery, service profile association, firmware activation, boot order, storage presentation, or management integration. The scenario points to fabric interconnect; that is why the selected action fixes the root condition rather than merely restarting the server. The wrong options either affect a different policy, require unnecessary disruption, or assume that physical connectivity alone is sufficient. Cisco documentation for UCS server boot and firmware management stresses that boot policies must include the correct target details, firmware workflows must complete their FSM stages, and hardware changes often require acknowledgement or re-acknowledgement before UCS Manager uses the new inventory. After remediation, the engineer should confirm that the UCS fault is cleared, the server association or discovery state is complete, and the operating system or management service can use the intended path.

The target of the configured zone does not match the target of the configured boot order is the required SAN-side correction. In Cisco storage fabrics, symptoms such as isolated ports, missing targets, failed zone merges, vFC down state, or inaccessible LUNs are rarely solved by changing a random endpoint setting. The engineer must validate the FC control-plane dependency associated with FLOGI, PLOGI, vNIC: VSAN assignment, trunk allowance, FSPF parameters, fcdomain uniqueness, NPIV support, NPV uplink behavior, DCBX/LLDP negotiation, and active zoning. The selected answer is the one that restores that dependency. Other choices may be valid operational commands in a different failure, but they do not address the precise point where fabric membership or access control is broken. Cisco guidance is to verify the active database and the operational database separately because a configured object is not necessarily active in the fabric. Post-remediation checks should include interface state, VSAN status, FLOGI/PLOGI, zoneset membership, and target visibility from the initiator.

The applet called “Backup” must include an action to remove the current static route is the valid corrective action because the failure described is a protocol or fabric state problem, not a generic connectivity issue. For Cisco Nexus, 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.

The correct action is the drag-and-drop mapping shown in the answer key. Cisco UCS troubleshooting depends on the relationship between policy, inventory discovery, firmware state, and server identity. The question involves firmware, fabric interconnect, so the selected option fixes the UCS component or policy that directly controls the failure. In UCS Manager, service profiles, vNIC/vHBA templates, boot policies, firmware packages, server pools, adapters, fabric interconnects, and I/O modules are applied through a managed model; a server can fail even when basic IP reachability exists if the relevant policy is incomplete or the hardware inventory has not been acknowledged correctly. The distractors typically change an unrelated object, force a disruptive recovery without fixing the policy, or apply to a different UCS mode. Cisco guidance is to verify faults, FSM stage, inventory status, association status, and the specific boot or connectivity policy before taking action. After the remediation, validate that the fault clears, the FSM completes, and the server or fabric component returns to the expected operable state.

Re-acknowledgement the server is the appropriate UCS remediation because the symptom maps to a specific managed object rather than a generic server failure. Cisco UCS abstracts hardware through service profiles and policies; therefore, issues involving UCS must be corrected where UCS Manager programs the adapter, boot target, firmware, management certificate, pool qualification, or fabric interconnect state. The selected answer restores that programming path. The other options may appear plausible, but they do not correct the object that UCS uses to derive operational state. For example, boot failures require the correct vHBA/iSCSI target and LUN policy, discovery issues require the proper physical and management path, and firmware failures require the documented recovery action for the failed FSM stage. The correct validation is to inspect the associated fault, confirm inventory acknowledgment, verify the policy under the service profile or equipment tree, and then recheck boot or connectivity behavior after the FSM completes.
