350-601 Compute Practice Test 2 — 15 Questions

Question 1

A Cisco UCS Manager administrator notices that a newly provisioned service profile is showing 'Config Error' for the vNIC. The vNIC is configured to use a dynamic MAC address from a pool that has no free addresses. What is the correct remediation?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Add more MAC addresses to the MAC pool used by the vNIC. The 'Config Error' for the vNIC indicates that the dynamic MAC address assignment failed because the MAC pool is exhausted. Adding more MAC addresses to the pool resolves the issue by providing available addresses for the vNIC to consume, allowing the service profile to deploy successfully.

Answer

Upgrade the firmware on the Fabric Interconnect

Answer

Change the vNIC to use a static MAC address

Answer

Reassociate the service profile to a different blade

Question 2

A data center engineer is planning a Cisco UCS deployment for a virtualized environment. The requirement is to maximize performance for virtual machine traffic while minimizing latency. Which feature should be enabled on the UCS Manager to offload packet processing from the host CPU?

Accepted Answer

Hardware VLAN tagging and checksum offload. Hardware VLAN tagging and checksum offload offloads packet processing tasks (VLAN insertion/stripping and checksum calculation) from the host CPU to the Cisco UCS virtual interface card (VIC) adapter. This reduces CPU overhead and minimizes latency for virtual machine traffic, directly meeting the requirement to maximize performance in a virtualized environment.

Answer

Data Center Ethernet (DCE) priority flow control

Answer

vNIC failover policy

Answer

Fibre Channel over Ethernet (FCoE) offload

Question 3

Which TWO are valid methods to configure a Cisco UCS service profile for stateless computing? (Choose two.)

Accepted Answer

Create a service profile from a template. Creating a service profile from a template is a core method for stateless computing in Cisco UCS. Stateless computing abstracts hardware identity (e.g., WWPNs, MAC addresses, UUIDs) from physical blades, allowing a service profile to be applied to any compatible blade without reconfiguration. Templates enable rapid, consistent deployment of these stateless profiles across multiple servers.

Answer

Use boot from SAN to store OS images

Answer

Assign persistent WWPNs to vHBAs

Answer

Configure local storage on the blade

Question 4

Which THREE are benefits of using Cisco UCS Manager to manage compute resources? (Choose three.)

Accepted Answer

Centralized management of multiple chassis. Cisco UCS Manager provides a single-pane-of-glass management interface that can centrally manage up to 160 chassis (including UCS 5108 and UCS 9508) in a single domain. This eliminates the need to configure each chassis individually, reducing operational overhead and ensuring consistent configuration across the entire compute infrastructure.

Answer

Direct management of virtual machines

Answer

Improved performance by disabling hardware features

Question 5

Refer to the exhibit. An administrator updates template-B but its associated profile SP2 shows 'unassigned'. The administrator wants SP2 to reflect the changes. What should be done first?

Accepted Answer

Associate SP2 with template-B using the 'bind' operation. In Cisco UCS Manager, a service profile (SP2) must be explicitly bound to a template (template-B) to inherit updates. The 'bind' operation associates the profile with the template, allowing changes made to the template to propagate to the profile. Simply disabling and re-enabling the template or waiting for automatic association does not establish this binding; the profile remains 'unassigned' until it is bound.

Answer

Disable and re-enable template-B

Answer

Wait for the automatic association to occur

Answer

Rebind all profiles to template-B

Question 6

A data center engineer notices that a UCS B-Series blade server is failing to boot from a SAN LUN that is correctly mapped to the server's WWPN. The SAN switch shows that the LUN is accessible and the zone is configured correctly. The UCS Manager shows the server's vNIC is associated with a vHBA that has the correct WWPN, but the server's BIOS does not list the Fibre Channel boot target. Which configuration is most likely missing?

Accepted Answer

The boot policy is not defined or not attached to the service profile.. The boot policy defines the boot order and parameters (such as the SAN LUN target WWPN and LUN ID) for the server. If the boot policy is not defined or not attached to the service profile, the UCS Manager will not program the BIOS with the Fibre Channel boot target information, even though the SAN zoning and vHBA WWPN are correct. Without this policy, the server's BIOS has no instruction to attempt a SAN boot, resulting in the failure described.

Answer

The SAN connectivity policy is missing the Fibre Channel uplink pinning.

Answer

The vNIC/vHBA placement policy is incorrectly set to 'Express' mode.

Answer

A QoS policy is not applied to the vHBA.

Question 7

Refer to the exhibit. An engineer applies this QoS policy to a Cisco Nexus 9000 switch in a data center. After applying the policy, storage traffic (iSCSI) is experiencing high latency and occasional drops. The engineer verifies that the iSCSI traffic is not matching the 'BulkData' class. What is the most likely cause of the issue?

Accepted Answer

The policy-map does not specify a priority queue for latency-sensitive traffic.. ISCSI is a latency-sensitive storage protocol that requires a strict priority queue to ensure low latency and minimal jitter. Without a priority queue configured in the policy-map, iSCSI traffic competes with other traffic classes on a best-effort basis, leading to high latency and drops even if it is not matching the 'BulkData' class.

Answer

The policy-map is applied at the system level, but iSCSI traffic is not classified under any class-map.

Answer

The bandwidth percent for class-default is too low, causing iSCSI to be starved.

Answer

The class-map 'BulkData' does not match the correct traffic because the match statement uses qos-group instead of dscp.

Question 8

A financial services firm has deployed Cisco UCS C-Series rack servers running VMware vSphere 7.0. They use Cisco Intersight for management. Recently, a critical application server (Server-A) became unresponsive. The Intersight dashboard shows the server's health status as 'Warning' with a firmware compliance alert: the server's Cisco Integrated Management Controller (CIMC) firmware version is 4.0(1a), while the Intersight firmware baseline is 4.2(1c). The server is running ESXi 7.0u2 on a local datastore. The storage is provided by a Cisco MDS switch via Fibre Channel. The server has two 10GbE uplinks to the fabric interconnect. The engineer notices that the vCenter Server cannot communicate with Server-A, and all VMs on that host are isolated. The engineer suspects the issue is related to the firmware mismatch. What is the most appropriate first step to resolve this issue while minimizing downtime?

Accepted Answer

Upgrade the CIMC firmware on Server-A from 4.0(1a) to 4.2(1c) using Intersight's firmware update capability.. The CIMC firmware mismatch (4.0(1a) vs. baseline 4.2(1c)) is a known cause of management-plane instability in Cisco UCS C-Series servers managed by Intersight. Upgrading the CIMC firmware to match the Intersight baseline using Intersight's built-in firmware update capability directly addresses the root cause, restoring proper communication between the server, Intersight, and vCenter, while minimizing downtime by avoiding disruptive OS-level changes.

Answer

Check vCenter logs to determine why communication failed.

Answer

Reinstall ESXi on Server-A to ensure a clean operating system.

Answer

Change the Intersight firmware baseline to match the current CIMC version (4.0(1a)).

Question 9

A large enterprise is using Cisco UCS Manager to manage a chassis with 8 B-Series blades. The environment uses a combination of Ethernet and Fibre Channel traffic. The UCS fabric interconnect (FI) is configured in end-host mode with two uplinks to the core network. Recently, the engineering team deployed a new service profile for a high-performance computing workload that requires 40Gbps Ethernet per vNIC and 16Gbps Fibre Channel per vHBA. The server has two vNICs and two vHBAs. After deployment, the server's OS shows only 10Gbps connectivity on each vNIC. The engineer checks UCS Manager and sees that the vNIC templates are set to '10 Gbps' and the vHBA templates are set to '16 Gbps' but the actual link speed for vNICs is only 10Gbps. The fabric interconnect ports are configured as 40Gbps uplinks. The engineer has verified that the server adapter supports 40Gbps. What is the most likely cause of the speed mismatch?

Accepted Answer

The vNIC template used in the service profile specifies a requested speed of '10 Gbps' instead of '40 Gbps'.. The vNIC template in the service profile defines the requested speed for the virtual NIC. If the template is set to '10 Gbps', the UCS Manager will allocate only 10 Gbps of bandwidth per vNIC, regardless of the physical adapter's capability or the uplink speed. Since the engineer verified the adapter supports 40 Gbps and the uplinks are 40 Gbps, the mismatch is directly caused by the template configuration.

Answer

The fabric interconnect uplinks are configured as 40Gbps, but the port channel is not configured correctly, causing speed negotiation to fail.

Answer

The server's adapter policy is set to 'Windows' mode, which limits Ethernet speeds to 10Gbps.

Answer

The QoS policy applied to the vNIC limits the bandwidth to 10Gbps.

Question 10

Accepted Answer

Fabric Interconnect: Manages network connectivity and provides management access.. The correct matches are: Fabric Interconnect provides network connectivity and management; UCS Manager provides unified management; Blade Chassis houses servers and provides power/cooling. Common confusions include swapping functions with I/O Module or between chassis and interconnect.

Answer

Fabric Interconnect: Houses blade servers and provides power and cooling.

Answer

UCS Manager: Connects blade chassis to fabric interconnects.

Answer

Blade Chassis: Provides network connectivity and management.

Question 13

Match each Cisco MDS FC switch feature to its purpose.

Accepted Answer

VSAN: Allows creation of virtual SANs to isolate traffic within a physical SAN. VSAN, Zoning, and NPV are correctly matched. FCoE encapsulates Fibre Channel over Ethernet, and DCNM provides centralized management. Common confusions include mixing VSAN with FCoE or DCNM with FCoE.

Answer

FCoE: Allows creation of virtual SANs to isolate traffic within a physical SAN

Answer

DCNM: Encapsulates Fibre Channel frames over Ethernet networks

Question 14

A data center administrator needs to deploy a new blade server in a Cisco UCS chassis. The server must automatically inherit the correct service profile based on its slot location. Which feature should be configured?

Accepted Answer

Qualifier-based service profile association. Qualifier-based service profile association allows a service profile to be automatically applied to a blade server based on its slot location within the UCS chassis. This is achieved by configuring a qualifier that matches the chassis ID and slot number, enabling automatic inheritance without manual intervention.

Answer

Static service profile association

Answer

Service profile template with pool

Answer

Default service profile

Question 15

An engineer is troubleshooting a UCS B-Series server that fails to boot from SAN. The SAN boot LUN is correctly zoned and presented. The service profile has WWPNs configured. What is a likely cause?

Accepted Answer

Incorrect boot policy order. The SAN boot LUN is correctly zoned and presented, and the WWPNs are configured in the service profile, so the connectivity and identity are set. However, if the boot policy order is incorrect (e.g., the SAN boot target is listed after a local disk or another boot device), the server will attempt to boot from the wrong device first and fail to boot from the SAN. The boot policy defines the sequence of boot devices, and a misconfigured order is a common cause of boot failures in UCS B-Series.

Answer

Server firmware mismatch

Answer

Missing vNIC template

Answer

VLAN mismatch
