Free Practice Questions for Cisco 300-615 Exam

Configure the Filter field with sAMAccountName=$company 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, UCS Manager, LDAP 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 correct remediation is interface eth1/1 auto-cost reference-bandwidth 10000. 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, 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 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.

The selected option, Reboot the guest shell, 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 Guest Shell, Bash, Cisco Nexus; 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.

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.

The correct answer is Enable priority flow control on the interface. 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 FCoE, 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.

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.
