Cisco Troubleshooting Cisco Data Center Infrastructure Sample Questions (Q89-Q94):

NEW QUESTION # 89
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?

A. Register the blade as an initiator on the storage array
B. Establish a Layer 2 connection between the blade and the storage
C. Implement a Layer 3 connection between the blade and the storage
D. Place VLAN 0 on the interface that connects to the storage

Answer: D

Explanation:
The correct answer is Place VLAN 0 on the interface that connects to the storage. 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 UCS, service profile, iSCSI, 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.

NEW QUESTION # 90
Refer to the exhibit. The EEM script overrides all events in the system policy.
What should be added to the script to resolve the issue?

A. event statement
B. environment variable
C. configure terminal action
D. event-default action statement

Answer: A

NEW QUESTION # 91
Refer to the exhibits.

An engineer troubleshoots switch N5K1, which fails to receive traffic from the file server Which set of actions resolves this problem?

A. Bind native VLAN 10 with Ethemet10/1/1 and allow VLAN 10 in trunk configuration
B. Assign native VLAN 10 with fc2.'l - 2 and allow VLAN 10 in trunk configuration.
C. Bind native VLAN 10 with Ethemet1/10 and allow VSAN 101 in trunk configuration.
D. Assign native VLAN 10 with vfc111 and allow VLAN 1101 in trunk configuration.

Answer: A

NEW QUESTION # 92
An engineer must upgrade all components in a Cisco UCS domain to the same package version, but the upgrade process fails to complete. Which set of Auto Install actions resolves the problem?

A. Install Hypervisor Firmware, then Install Infrastructure Firmware
B. Install Server Firmware, then Install Infrastructure Firmware
C. Install infrastructure Firmware, then Install Hypervisor Firmware.
D. Install Infrastructure Firmware, then Install Server Firmware.

Answer: D

Explanation:
Install Infrastructure Firmware, then Install Server Firmware is correct because the failure is tied to the UCS managed state of UCS, firmware, Auto Install. 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.

NEW QUESTION # 93
Refer to the exhibit.

The initiator that has FC ID 0x970102 fails to communicate with the target that has FC ID 0x970200. What action resolves the issue?

A. Reactivate the zoneset.
B. Reset the port for FC ID 0x970102 and FC ID 0x970200 to log in to the fabric.
C. Reconfigure the initiator and the target to be in the same zones.
D. Reset the port for FC ID 0x970209 and FC ID 0x9700c2 to log in to the fabric.

Answer: C
