Configure the pinning max-link as 2 is the valid corrective action because the failure described is a protocol or fabric state problem, not a generic connectivity issue. For LACP, FEX, 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.

Enable BGP advertise pip feature on both leaf switches is the valid corrective action because the failure described is a protocol or fabric state problem, not a generic connectivity issue. For VXLAN, NVE, 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. 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.

Leaf101# setup-clean-config.sh Leaf101# reload 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.

Reregister the site in the Nexus Dashboard GUI is correct because the failure is an operations-plane condition involving ACI, APIC, Nexus Dashboard, Cisco Nexus. In Cisco data center products, management functions depend on more than IP connectivity. AAA servers must return the correct attributes, RBAC must map users to the correct security domain or role, certificates must be trusted and valid for the access method, and firmware or registration workflows must satisfy documented prerequisites such as NTP and required ports. The selected answer corrects that dependency. The distractors are not root-cause fixes because they either target a different subsystem or change a setting that would not influence the observed login, registration, warning, or fault. After the change, validation should include a successful login or registration test, review of the audit/fault record, and confirmation that the expected administrative scope is enforced. That approach matches Cisco operational troubleshooting for DCIT environments.

Enable NPIV on the upstream switch that connects the port 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 NPIV, Cisco Nexus: 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.

Bind native VLAN 10 with Ethemet10/1/1 and allow VLAN 10 in trunk configuration is the correct fix under Cisco SAN troubleshooting practice. The issue described involves VSAN, 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.

Configure the role name to match the group name on Microsoft Active Directory is the correct fix under Cisco SAN troubleshooting practice. The issue described involves MDS, 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.

Manually configure DNS in the Guest shell, even if it is claimed on the Cisco Nexus switch through DHCP is the required fix because the automation failure is caused by execution context, syntax, or resource state around Guest Shell, Cisco Nexus. 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.

Cisco troubleshooting logic supports Resolve unicast reply from Router R2 as the required fix. In this question the symptoms point to OSPF, 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.

The correct answer is the selected command set. Cisco MDS and Nexus SAN troubleshooting is driven by fabric state: the host and target must be in the correct VSAN, must complete FLOGI/PLOGI where applicable, and must be permitted by active zoning, fcdomain, FSPF, NPV/NPIV, or port-security policy. This question focuses on VSAN, fabric binding, so the selected action fixes the dependency that prevents the initiator, target, or inter-switch link from becoming usable. Cisco documentation emphasizes checking VSAN membership, active zonesets, correct port mode, fabric binding, device-alias consistency, and the relevant FC databases before changing unrelated server settings. The distractors either target a different database, use the wrong port role, or would not cause the observed Fibre Channel state to change. After the fix, the engineer should confirm the interface state, FLOGI database, name-server entries, zoneset activation, and successful initiator-to-target reachability with tools such as fcping or fabric show commands.
