350-601 Practice Test 27 — 15 Questions

Question 1

Refer to the exhibit. An engineer notices intermittent packet loss on interface Ethernet 1/1 of the Fabric Interconnect. Based on the transceiver statistics shown, which condition is the most likely cause?

Accepted Answer

The receive power is below the low warning threshold.. The exhibit shows that the receive power is -16.3 dBm, which is below the low warning threshold of -13.3 dBm. This indicates the incoming optical signal is too weak, causing intermittent packet loss due to bit errors or link flaps. The transceiver statistics confirm that the receive power is the only parameter breaching its threshold, making it the most likely cause.

Answer

The supply voltage is out of range.

Answer

The transmit power is too low.

Answer

The transceiver temperature is too high.

Question 2

A UCS administrator needs to ensure that server boot order always starts from the local disk if available, and falls back to a SAN LUN if local disk fails. Which boot policy setting should be used?

Accepted Answer

Local Disk first, then SAN. Option D is correct because the UCS boot policy allows you to specify a boot order where the local disk is attempted first. If the local disk is unavailable or fails, the system automatically falls back to the next boot device in the list, which is the SAN LUN. This ensures high availability and aligns with the requirement to prefer local boot while providing a failover path.

Answer

Local Disk alone

Answer

SAN first, then Local Disk

Answer

SAN Boot Only

Question 3

Refer to the exhibit. A UCS B-Series blade shows a failed power supply. The blade is currently running. Which action should the engineer take to replace the power supply without causing service disruption?

Accepted Answer

Replace the failed power supply while the blade remains powered on.. Option D is correct because UCS B-Series blades use a shared chassis power infrastructure with N+1 redundancy. The failed power supply can be hot-swapped while the blade remains powered on, as the remaining power supplies in the chassis will continue to provide power without interruption. No blade isolation or shutdown is required, as the chassis power subsystem is designed for concurrent maintenance.

Answer

Replace the power supply only after the blade is isolated from the fabric.

Answer

Replace the failed power supply in the chassis without affecting the blade.

Answer

Shut down the blade, replace the power supply, then power on.

Question 4

A UCS domain is configured with multiple service profile templates. An engineer wants to ensure that when a template is updated, all associated service profiles are automatically updated. Which property must be enabled in the template?

Accepted Answer

'Update on deployment'. The 'Update on deployment' property, when enabled in a service profile template, ensures that any changes made to the template are automatically applied to all associated service profiles during the next deployment or re-deployment. This is the correct mechanism in Cisco UCS Manager to propagate template updates to existing service profiles without manual intervention.

Answer

'Auto update'

Answer

'Enforce consistency'

Answer

'Synchronize to templates'

Question 5

An engineer needs to deploy a new UCS C-Series standalone server in a remote branch without local IT staff. Which technology allows remote firmware upgrade and hardware monitoring without requiring a dedicated management IP?

Accepted Answer

Cisco Intersight. Cisco Intersight is a cloud-based management platform that provides out-of-band management for UCS C-Series standalone servers without requiring a dedicated management IP address. It uses a device connector embedded in the CIMC to establish a secure connection to the Intersight cloud, enabling remote firmware upgrades, hardware monitoring, and lifecycle management over the internet. This eliminates the need for a separate management network or local IT staff at the remote branch.

Answer

Cisco Integrated Management Controller (CIMC) GUI

Answer

UCS Manager

Answer

Data Center Network Manager (DCNM)

Question 6

Refer to the exhibit. A UCS administrator applies a service profile with this boot policy to a blade. The blade boots from the SAN LUN successfully. However, after a reboot due to a firmware update, the blade boots from the local disk instead of the SAN. What is the most likely reason?

Accepted Answer

The boot order has local disk before the SAN target.. The most likely reason is that the boot order in the service profile's boot policy lists the local disk before the SAN target. After a firmware update, the UCS Manager re-evaluates the boot policy, and if the local disk is present and has a higher priority, the blade will boot from it instead of the SAN LUN. The initial successful boot from SAN occurred because the local disk was not present at that time, but after the reboot, the local disk became available and took precedence.

Answer

The WWPN of the SAN target is incorrect.

Answer

The SAN target LUN ID changed after the firmware update.

Answer

The local disk was not present at initial association.

Question 7

In a Cisco HyperFlex cluster, the management plane uses vCenter, but the data plane uses which protocol to replicate data across nodes?

Accepted Answer

HX Data Platform. In a Cisco HyperFlex cluster, the data plane replication across nodes is handled by the HX Data Platform, which is a distributed, log-structured file system that synchronously replicates data at the hypervisor level. This platform manages all I/O operations and ensures data consistency across the cluster without relying on external storage protocols like Fibre Channel or iSCSI.

Answer

Fibre Channel

Answer

NFS

Answer

iSCSI

Question 8

A company recently deployed Cisco UCS B-Series blades with a single Fabric Interconnect. During a maintenance window, the Fabric Interconnect must be upgraded. Which action ensures minimal disruption to running workloads?

Accepted Answer

Disassociate service profiles from blades, upgrade the Fabric Interconnect, then re-associate the service profiles.. Option A is correct because disassociating service profiles from the blades detaches the logical configuration from the physical hardware, allowing the single Fabric Interconnect to be upgraded without affecting the running workloads. The blades continue to run their current operating system and applications, and once the upgrade is complete, re-associating the service profiles restores management connectivity without requiring a reboot or workload interruption.

Answer

Use the UCS Manager GUI to migrate all service profiles to a second Fabric Interconnect.

Answer

Shut down all blades gracefully, upgrade the Fabric Interconnect, then power on blades.

Answer

Change the boot order of blades to boot from NFS image, then upgrade FI.

Question 9

A UCS administrator is deploying a 3-node HyperFlex cluster with vSphere. Each node has a single vNIC for management and two vNICs for storage data traffic. During the cluster creation, the storage vNIC MTU must be configured. What is the recommended MTU value for the storage data vNICs in HyperFlex?

Accepted Answer

9000. C is correct because HyperFlex storage data vNICs require jumbo frame support to optimize storage traffic performance. The recommended MTU value for these vNICs is 9000, which allows larger packet sizes and reduces CPU overhead for storage I/O operations. This value is consistent with Cisco's best practices for HyperFlex cluster deployments.

Answer

1500

Answer

9216

Answer

4096

Question 10

During a UCS firmware upgrade, the upgrade fails on a few servers in a chassis. The administrators notice that the management plane is still responsive, but the data plane is disrupted. What is the most likely cause?

Accepted Answer

The secondary Fabric Interconnect did not synchronize the firmware image before the upgrade.. The most likely cause is that the secondary Fabric Interconnect did not synchronize the firmware image before the upgrade. In a UCS domain, firmware upgrades are typically performed in a hitless manner by first upgrading the secondary Fabric Interconnect, which requires the firmware image to be synchronized from the primary. If synchronization fails, the secondary may boot with an incompatible or missing firmware, causing data plane disruption while the management plane remains responsive because the primary still handles management traffic.

Answer

The boot policy was changed during maintenance.

Answer

The server memory is exhausted due to high traffic.

Answer

The service profiles were not updated after the upgrade.

Question 11

A CCNP engineer is troubleshooting a UCS environment where a server is stuck in 'Discovery: In Progress' state. The chassis has been power-cycled, but the issue persists. FEX fabric port is configured correctly. What is the most likely cause?

Accepted Answer

Firmware version mismatch between the server's CIMC and the Fabric Interconnect.. When a server is stuck in 'Discovery: In Progress' state and the chassis has been power-cycled with correct FEX fabric port configuration, the most likely cause is a firmware version mismatch between the server's Cisco Integrated Management Controller (CIMC) and the Fabric Interconnect (FI). During discovery, the FI attempts to inventory and manage the server via CIMC; if the firmware versions are incompatible, the discovery process cannot complete, leaving the server in a perpetual 'In Progress' state.

Answer

Incorrect IP address on the Fabric Interconnect management interface.

Answer

The chassis is not connected to the FI via a valid fabric cable.

Answer

The server's service profile is not associated.

Question 12

A UCS administrator notices that a server in a UCS domain is not booting from SAN after a firmware upgrade. The service profile shows the correct WWPN and boot policy. The SAN switch sees the initiator login. However, the storage array does not see any initiator attempts. What is the most likely issue?

Accepted Answer

The zone alias on the SAN switch does not match the initiator WWPN. The SAN switch sees the initiator login, but the storage array does not see any initiator attempts. This indicates that the Fibre Channel fabric is blocking the initiator's WWPN from reaching the storage target, typically because the zone configuration on the SAN switch does not include the initiator's WWPN or the zone alias does not match the actual WWPN. Since the service profile and boot policy are correct, and the VSAN membership is functional (the switch sees the login), the most likely issue is a zoning mismatch on the SAN switch.

Answer

The boot policy is missing the primary SAN target

Answer

The WWPN is duplicated on another initiator

Answer

The VSAN membership is incorrect on the fabric interconnect

Question 13

A storage administrator reports that a Cisco UCS domain is not booting from the Fibre Channel SAN. The boot policy is correctly configured and the vHBA is associated. Which two alignment issues could cause this problem? (Choose two.)

Accepted Answer

The WWPN of the vHBA is not zoned on the SAN fabric.. Option A is correct because if the WWPN of the vHBA is not properly zoned on the SAN fabric, the Fibre Channel switch will not allow the server to log in to the target storage. Even with a correct boot policy and vHBA association, without zoning, the initiator cannot discover or communicate with the boot LUN, causing the boot to fail.

Answer

The Ethernet LAN is not configured on the FI.

Answer

The disk firmware on the server is outdated.

Question 14

Refer to the exhibit. The server in slot 2 is associated and working. A new server is inserted into slot 1, but after 30 minutes it remains in 'Unassigned' state. What is the most likely reason?

Accepted Answer

The server's CIMC firmware is not compatible with the Fabric Interconnect firmware.. The server in slot 1 remains in 'Unassigned' state because its CIMC firmware is incompatible with the Fabric Interconnect firmware. In Cisco UCS, the CIMC on each blade must match a supported firmware version for the Fabric Interconnect to discover and manage the server. When firmware versions are mismatched, the server cannot transition to the 'Associated' state and stays 'Unassigned'.

Answer

The service profile is already associated with another server.

Answer

The server is not powered on.

Answer

The Fabric Interconnect ports are not configured as server ports.

Question 15

Which THREE conditions must be met before a UCS Fabric Interconnect can be part of a port channel? (Select THREE.)

Accepted Answer

All ports must be on the same side of the switch (either all uplink or all server-facing).. Option B is correct because in a UCS Fabric Interconnect, a port channel can only be formed using ports that are all on the same side of the switch—either all uplink ports (connecting to the upstream network) or all server-facing ports (connecting to FEX or servers). Mixing uplink and server-facing ports in a single port channel is not supported due to the distinct forwarding behaviors and VLAN configurations applied to each port type.

Answer

Ports should come from different FEX modules for redundancy.

Answer

Ports should be configured as admin down until the port channel is formed.
