350-601 Compute Practice Test 4 — 15 Questions

Question 1

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. 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 2

During a capacity planning review, an engineer notices that a UCS domain with 8 blades (each with 16 cores) is using 70% CPU average. The environment runs VDI workloads. Each VM requires 2 vCPUs and 4 GB RAM. The hypervisor uses 1:1 CPU oversubscription. How many additional VMs can be deployed before reaching 100% CPU utilization?

Accepted Answer

19. The UCS domain has 8 blades × 16 cores = 128 cores. With 1:1 CPU oversubscription, the hypervisor can allocate 128 vCPUs. Each VM requires 2 vCPUs, so the maximum VMs are 128 / 2 = 64. Currently at 70% CPU, 0.70 × 128 = 89.6 vCPUs are used, meaning 89.6 / 2 = 44.8 VMs (round to 45 VMs). The remaining vCPUs are 128 - 89.6 = 38.4, allowing 38.4 / 2 = 19.2 additional VMs, so 19 VMs can be deployed before hitting 100% CPU utilization.

Question 3

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 4

A UCS domain has two Fabric Interconnects in end-host mode. Which statement about server-side traffic is true?

Accepted Answer

The Fabric Interconnect learns server MAC addresses on the server-facing ports.. In end-host mode, the Fabric Interconnect (FI) acts as a Layer-2 forwarding device that learns server MAC addresses on the server-facing ports to build its forwarding table. This is required because the FI does not run Spanning Tree Protocol (STP) on those ports; instead, it relies on MAC learning to forward traffic correctly between servers and the upstream network.

Answer

Fabric Interconnects run IEEE 802.1D STP on the server-facing ports.

Answer

The Fabric Interconnect performs VLAN-based load balancing to the upstream network.

Answer

Each Fabric Interconnect independently forwards frames to the upstream switches using the same uplink.

Question 5

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.

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

Which feature in UCS Manager allows centralized management of firmware policies across multiple chassis without creating a separate policy for each chassis?

Accepted Answer

Firmware Policy. B is correct because a Firmware Policy in UCS Manager allows you to define a single firmware version and package that can be applied to multiple chassis or service profiles. This centralized approach eliminates the need to create a separate firmware policy for each chassis, as the policy is simply associated with the desired chassis or service profile templates.

Answer

Maintenance Policy

Answer

Host Firmware Package

Answer

Adapter Policy

Question 8

Which TWO statements about Cisco UCS service profiles are correct? (Choose TWO.)

Accepted Answer

Service profiles can include policies for firmware management.. Cisco UCS service profiles can include firmware management policies that specify the firmware versions to be applied to the associated server components, such as adaptors, BIOS, and storage controllers. This allows administrators to enforce consistent firmware levels across the infrastructure without manual intervention.

Answer

Service profiles are only supported on B-Series blades.

Answer

Service profiles are tied to specific physical hardware.

Answer

A service profile does not include network identity settings such as MAC addresses.

Question 9

Which THREE factors should be considered when determining the number of upstream Ethernet uplinks from a UCS Fabric Interconnect to the core network? (Choose THREE.)

Accepted Answer

The number of vNICs per service profile and their bandwidth limits.. The number of vNICs per service profile and their bandwidth limits directly determine the aggregate traffic that must be carried by the upstream Ethernet uplinks. Each vNIC is assigned a specific bandwidth cap (e.g., via QoS policy or vNIC template), and the sum of these caps across all service profiles on a Fabric Interconnect dictates the minimum uplink capacity required to avoid oversubscription.

Answer

Number of VLANs defined on the Fabric Interconnect.

Answer

Server CPU oversubscription ratio.

Question 10

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.. 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 11

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 12

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 13

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.. 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 14

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.. 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 15

An organization is deploying Cisco UCS and needs to ensure that server personality is maintained even after a new server is added to the chassis. Which policy should be configured to achieve this?

Accepted Answer

Server Pool Policy. The Server Pool Policy is correct because it defines a logical grouping of servers that can be dynamically assigned to service profiles. When a new server is added to the chassis and matches the pool criteria, the policy ensures that the server automatically inherits the correct personality (e.g., UUID, WWN, MAC addresses) from the associated service profile template, maintaining consistency without manual intervention.

Answer

UUID Suffix Pool

Answer

Maintenance Policy

Answer

Boot Policy
