Cisco Troubleshooting Cisco Data Center Infrastructure Sample Questions (Q100-Q105):

NEW QUESTION # 100
Refer to the exhibit.

The connection between a Cisco Nexus 5548UP switch and a Cisco MDS switch fails to initialize. What is the cause of the issue?

Answer: C

Explanation:
The selected resolution is VSAN 1 is suspended because the failure is in the Fibre Channel/FCoE control path around MDS, VSAN, Cisco Nexus. 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.


NEW QUESTION # 101
A network engineer experiences the error "DDR3_P1_B1_ECC" when upgrading Cisco UCS firmware. Which action resolves the issue?

Answer: D


NEW QUESTION # 102
Refer to the exhibit.

A switch is being downgraded to an earlier release because of a problem with the current release. After the switch is downgraded, it can no longer forward traffic. Which action resolves the issue?

Answer: B

Explanation:
The answer is Roll back to the original image because Cisco Nexus and ACI forwarding depends on exact agreement between the devices participating in the feature. The scenario references FEX; those technologies fail in predictable ways when required parameters do not match or when the required control-plane advertisement is absent. In DCIT troubleshooting, the engineer should identify the failed dependency, correct that dependency, and then verify the operational table that proves the fix. For example, vPC and EVPN checks focus on consistency, VNI/VRF bindings, peer-gateway behavior, and host-route advertisement; routing checks focus on neighbor state, MTU, timers, authentication, next-hop, and route preference. The selected answer addresses the dependency that blocks forwarding. The distractors are plausible because they touch related features, but they do not resolve the specific failure condition. Post-change validation should include protocol state, learned endpoint or route entries, and a traffic test across the affected path.


NEW QUESTION # 103
Refer to the exhibit.

A Cisco UCS B-Series Blade Server is configured to boot from a shared storage via an iSCSI network. When a service profile is associated with the blade, the blade fails to attach the LUN. Which action resolves the issue?

Answer: B
