350-601 Practice Test 26 — 15 Questions

Question 1

An engineer is designing a UCS Mini deployment for a remote office. The chassis will contain four blade servers. Each server needs two 10GbE connections for data and one 1GbE for management. What is the minimum number of fabric interconnects required?

Accepted Answer

One. A single UCS Mini fabric interconnect (FI) can provide both data and management connectivity for up to eight blade servers in a single chassis. Each blade server requires two 10GbE data connections (from the integrated VIC) and one 1GbE management connection (from the Cisco Integrated Management Controller, or CIMC). The FI aggregates these connections internally, so one FI is sufficient for a four-server deployment, as UCS Mini supports a single FI configuration for non-redundant setups.

Answer

Three

Answer

Four

Answer

Two

Question 2

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 3

A UCS domain is experiencing intermittent storage connectivity. The storage admin confirms the SAN is properly zoned and the VSANs are configured. The UCS admin finds that the host interface (HBAs) are showing 'Link Down' intermittently. Which of the following is a likely cause?

Accepted Answer

Faulty SFP or cable. Intermittent 'Link Down' on HBAs, despite correct SAN zoning and VSAN configuration, strongly points to a physical-layer issue. Faulty SFPs or damaged cables cause intermittent link flaps, which manifest as sporadic HBA link-down events. This is the most common cause of such symptoms in UCS environments.

Answer

Incompatible HBA firmware

Answer

Mismatched fabric failover policy

Answer

Incorrect Fibre Channel interface mode on the FI

Question 4

A Cisco UCS C-Series rack server requires remote management with KVM and virtual media. Which feature must be enabled?

Accepted Answer

CIMC. The Cisco Integrated Management Controller (CIMC) is the dedicated management interface on UCS C-Series rack servers that provides out-of-band remote management capabilities, including KVM console access and virtual media (vMedia) for mounting ISO images. Without CIMC enabled, these remote management features are unavailable, as they rely on its embedded web GUI, CLI, or API.

Answer

vMedia

Answer

BIOS

Answer

SOL

Question 5

An engineer notices that a UCS server with a service profile using a QoS policy for FC traffic experiences excessive latency during heavy workloads. The Fibre Channel fabric is configured for lossless operation. Which design issue is most likely causing the latency?

Accepted Answer

The QoS policy for FC traffic does not allocate enough buffer for the no-drop class.. The excessive latency during heavy workloads in a lossless Fibre Channel fabric is most likely due to insufficient buffer allocation for the no-drop class in the QoS policy. In UCS, the no-drop class (typically class-fcoe) must have adequate buffer space to prevent frame drops that trigger retransmissions and latency. Without enough buffer, the switch cannot absorb bursts, leading to congestion and increased latency even though the fabric is lossless.

Answer

The MTU on the Ethernet uplink from the FI is set to 1500 bytes.

Answer

Fibre Channel buffer-to-buffer credit recovery is disabled on the upstream switch.

Answer

The vHBA is configured for 16 Gbps but the upstream switch port is 8 Gbps.

Question 6

An engineer has configured a service profile with a WWPN pool that has exhausted its assigned range. The server boots from SAN. What happens when the server is associated?

Accepted Answer

The server associates with a temporary WWPN from the conflict-free range.. When a WWPN pool is exhausted, Cisco UCS automatically assigns a temporary WWPN from the conflict-free range (00:00:00:00:00:00 to 00:00:00:00:00:FF) to allow the server to associate and boot from SAN. This temporary WWPN is used only until a permanent WWPN becomes available from the pool, ensuring the server can still access storage during the interim period.

Answer

The server associates but fails to boot because no WWPN is assigned.

Answer

The administrator is prompted to manually enter a WWPN.

Answer

The association fails until new WWPNs are added to the pool.

Question 7

A data center administrator reports that traffic from a specific UCS server is not flowing through the expected Fabric Interconnect (FI) A. The pin group is configured, but traffic is still sent to FI B. What should the administrator check?

Accepted Answer

Ensure the vNIC's fabric ID is set to match the pin group's preferred fabric.. The pin group configuration determines which Fabric Interconnect a vNIC should use for upstream traffic. If the vNIC's fabric ID is not set to match the pin group's preferred fabric, the server will ignore the pin group and send traffic to the other FI. Option D is correct because the fabric ID mismatch causes the pin group to be ineffective, and verifying this alignment ensures traffic flows through the expected FI A.

Answer

Verify that the server is associated with the correct service profile.

Answer

Reboot the Fabric Interconnect.

Answer

Check if the pin group is deleted.

Question 8

A data center administrator is troubleshooting slow storage performance on a UCS B-Series blade server. The server is connected to a Cisco UCS 6300 Series Fabric Interconnect and uses local SAS drives. The administrator checks the UCS Manager and sees that the storage adapter has a driver version that is not recommended. What is the most likely impact of using a non-recommended driver version?

Accepted Answer

Degraded storage performance or instability. Using a non-recommended driver version for the storage adapter in a UCS B-Series blade server can lead to degraded storage performance or system instability. Cisco validates specific driver versions for compatibility with the UCS 6300 Series Fabric Interconnect and local SAS drives; deviations may cause suboptimal I/O handling, increased latency, or unexpected errors. This is a common issue in compute environments where driver- firmware mismatches affect storage throughput.

Answer

Loss of redundancy on the fabric interconnect

Answer

Inability to boot the server

Answer

Increased security vulnerabilities

Question 9

An engineer is configuring a UCS server for VMware ESXi. The service profile must support NPIV for virtual machine SAN connectivity. Which two conditions must be met? (Choose two.)

Accepted Answer

The WWPN must be unique per virtual machine. Option A is correct because NPIV (N_Port ID Virtualization) requires each virtual machine to have a unique World Wide Port Name (WWPN) so that the SAN fabric can distinguish and manage each VM's storage traffic independently. This allows multiple virtual machines to share a single physical HBA while each appears as a separate initiator to the SAN.

Answer

The vHBA must be set to 'Fabric: A' only

Answer

The vHBA must be set to 'Fabric: dual' mode

Answer

The vHBA must be created with a fabric failover policy

Question 10

A network engineer needs to create a consistent QoS policy for all servers in a UCS service profile template. Which policy must be attached to the template to ensure uniform traffic management?

Accepted Answer

QoS Policy. A QoS Policy is the correct attachment because it defines traffic classification, marking, and queuing behavior at the interface level within a UCS service profile template. By applying a QoS Policy, the engineer ensures uniform traffic management across all servers by controlling bandwidth allocation, priority, and drop preferences consistently. This policy directly maps to the system class definitions in UCS Manager, enabling per-interface QoS settings that are inherited by all service profiles using the template.

Answer

Network Control Policy

Answer

LAN Connectivity Policy

Answer

Flow Control Policy

Question 11

A UCS Manager administrator is deploying a service profile for a boot-from-SAN environment. The SAN switch is configured with NPV mode. The administrator notices that the WWPN of the vHBA in the service profile is not being recognized by the SAN switch. What is the most likely cause?

Accepted Answer

The upstream SAN switch has NPIV disabled. In a boot-from-SAN environment with NPV mode on the SAN switch, the upstream switch must have NPIV (N_Port ID Virtualization) enabled to allow multiple FCIDs to be assigned to a single physical link. Without NPIV, the upstream switch rejects the WWPN of the vHBA because it cannot support the virtualized N_Port IDs required for the service profile's vHBA to log in. This is the most likely cause of the WWPN not being recognized.

Answer

The WWPN pool has been exhausted and the server cannot obtain a new WWPN

Answer

The vHBA is not bound to a SAN pin-group

Answer

The vHBA speed is set to auto-negotiation but the SAN switch is set to a fixed speed

Question 12

An engineer is troubleshooting a UCS B-Series blade that fails to boot from SAN. Which TWO actions should be verified first? (Choose TWO.)

Accepted Answer

Verify that the vHBA WWPN is correctly zoned on the SAN switches.. Option A is correct because the vHBA WWPN must be properly zoned on the SAN switches to allow the blade to discover and connect to the storage target. Without correct zoning, the Fibre Channel initiator cannot communicate with the target, preventing SAN boot. This is a fundamental prerequisite for any Fibre Channel-based boot.

Answer

Check the MAC address assigned to the vNIC.

Answer

Ensure the QoS policy for FC traffic is set to Platinum.

Answer

Verify the server's boot order lists local disk first.

Question 13

Which three components are required to boot a UCS blade server from SAN? (Choose three.)

Accepted Answer

SAN boot target LUN. A SAN boot target LUN is required because the UCS blade server needs a specific logical unit number (LUN) on the storage array from which to boot the operating system. Without a designated boot LUN, the server has no target storage device to load the OS from over the Fibre Channel (FC) or FCoE SAN fabric.

Answer

iSCSI adapter

Answer

vNIC

Question 14

Which best practice should be followed when creating a UCS service profile template for stateless computing?

Accepted Answer

Assign MAC and WWN addresses from pools. Stateless computing in UCS requires that all server identity information, such as MAC addresses and WWNs, be abstracted away from the hardware and assigned dynamically from pools. This allows the service profile to be applied to any compatible blade or rack server without manual reconfiguration, enabling rapid provisioning and seamless hardware replacement. Defining these addresses directly in the profile or using static assignments would break the stateless model by tying the profile to specific hardware.

Answer

Use local storage on each server for boot images

Answer

Configure Windows Server NIC teaming for all vNICs

Answer

Define MAC addresses directly in the service profile

Question 15

An administrator needs to reset the CIMC password on a Cisco UCS C-Series server without physical access. Which method can be used?

Accepted Answer

Use the CIMC XML API. The CIMC XML API allows remote management of Cisco UCS C-Series servers, including password resets, without physical access. This API provides a programmatic interface to CIMC functions, enabling administrators to send authenticated XML requests over HTTPS to reset the CIMC password. Physical access is not required because the API operates over the network, making it the correct method for this scenario.

Answer

Use the front panel reset button

Answer

Use UCS Manager

Answer

Connect via serial console during boot
