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

The selected answer, the selected actions, 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 UCS, firmware, Auto Install, 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 selected resolution is Remove all of the local storage that is installed because the failure is in the Fibre Channel/FCoE control path around UCS, UCS Manager, SAN boot. 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.

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.

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.

1. Verify the FSM status on the server. 2. Decommission the impacted server. 3. Reset the slot where the server is located. 4. Recommission 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, firmware 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.

The selected resolution is Enable N9K-1 mode to N-Port ID Virtualization because the failure is in the Fibre Channel/FCoE control path around 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.

Cisco troubleshooting logic supports EVPN Type 1-5 as the required fix. In this question the symptoms point to EVPN, 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.

Shut and no shut the interface Eth0/I is correct because the failure is an operations-plane condition involving 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.

The selected resolution is • Set ESX01_B zone to VSAN 20. • Change vHBA1 to VSAN 20 in Service Profile because the failure is in the Fibre Channel/FCoE control path around VSAN, service profile, vHBA. 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.
