350-601 Compute Practice Test 12 — 15 Questions

Question 1

A service profile is configured to boot from local disk, but the blade server has no local storage. What will happen when the blade is associated with this service profile?

Accepted Answer

The blade will fail to boot and the operating system will not load.. UCS Manager does not validate hardware capabilities at association time. The blade will boot and fail to find a boot device, resulting in a boot failure. The service profile can still be associated.

Answer

The service profile will automatically change the boot policy to SAN.

Answer

The association will fail with an error message.

Answer

The blade will boot from SAN automatically as a fallback.

Question 2

A HyperFlex cluster uses RF2 and consists of 5 nodes. One node fails. Data is re-replicated to the remaining nodes. After re-replication, what is the largest number of additional node failures that can occur without data loss?

Accepted Answer

1. With RF2 (two copies), the cluster can tolerate one failure. After a failure and re-replication, the cluster has 4 nodes. If one more node fails, data might still be available if the surviving node holds a copy. However, with RF2, a second failure could lead to data loss if both copies are lost. The maximum tolerable is one additional failure, because with two failures, some data may have only one copy left (if the second failure affects the only remaining copy). Actually, with RF2, you can tolerate one failure. After re-replication, same tolerance: one more failure. So answer is 1.

Question 3

An administrator needs to perform a remote firmware upgrade on a UCS C220 rack server. The server has CIMC configured with an IP address. Which method should the administrator use to upgrade the CIMC firmware?

Accepted Answer

Use the CIMC web interface to upload and apply the firmware image.. CIMC supports firmware upgrade via its web interface or CLI using protocols like HTTP, TFTP, or SCP. The recommended method is to use the CIMC GUI or the 'update firmware' command in CIMC.

Answer

Use the KVM console to boot from a firmware upgrade ISO.

Answer

Use UCS Manager to upgrade the firmware of the C-series server.

Answer

Use Cisco IMC Supervisor to upgrade firmware across multiple servers.

Question 4

In a UCS service profile, which construct is used to abstract the network interface configuration so that the same profile can be used with different blade models?

Accepted Answer

vNIC template. vNIC templates define network interface properties (MAC address, VLANs, fabric assignment) and can be policy-based, allowing hardware abstraction.

Answer

Boot policy

Answer

Local disk policy

Answer

Server pool policy

Question 5

A HyperFlex cluster requires a cluster witness VM for quorum. The cluster is deployed with 5 nodes using RF2. If one node fails, the cluster remains operational. However, if a second node fails simultaneously, what determines whether the cluster remains available?

Accepted Answer

The witness VM provides the extra vote to maintain quorum.. The witness VM provides a tie-breaking vote. With RF2, if two nodes fail, the cluster can still maintain quorum if the witness is available. The witness is critical for clusters with even number of nodes or after failures.

Answer

The cluster automatically reverts to RF1 to stay operational.

Answer

The remaining data copies (2 per chunk) ensure no data loss.

Answer

The replication factor (RF2) alone ensures availability.

Question 6

An engineer is configuring a UCS service profile for PXE boot. The server must obtain an IP address from a DHCP server and then download the OS image from a TFTP server. Which boot policy parameters must be configured?

Accepted Answer

Add a LAN boot entry and select the appropriate vNIC for PXE.. PXE boot requires specifying the LAN boot option with the appropriate vNIC. In UCS, the boot policy can include a PXE boot entry that references a vNIC. DHCP and TFTP servers are configured externally; the boot policy just needs to enable PXE on the correct interface.

Answer

Configure the boot policy to use iSCSI boot.

Answer

Specify the DHCP server IP and TFTP server IP in the boot policy.

Answer

Select the SAN boot option and specify the WWPN.

Question 7

A UCS B-series blade server is experiencing boot issues. The service profile is configured to boot from local disk first, then SAN. The blade has local disks but they are not recognized. Which TWO actions should be taken to diagnose the issue?

Accepted Answer

Review the local disk configuration policy and RAID settings.. Possible causes: local disk not connected, or RAID configuration missing. Checking physical presence in CIMC and verifying RAID configuration are logical first steps.

Answer

Verify the boot policy in the service profile.

Answer

Re-associate the service profile.

Answer

Check the Fibre Channel fabric connectivity.

Question 8

A HyperFlex cluster with 6 nodes using RF3 experiences a node failure. After the failed node is replaced, the administrator notices degraded performance. Which THREE factors could contribute to the performance degradation?

Accepted Answer

The cluster is rebalancing data across all nodes.. During re-replication, there is increased I/O and CPU load. Additionally, if the replacement node is slower (e.g., fewer SSDs) or if the cluster is rebalancing, performance can suffer.

Answer

The witness VM is offline.

Answer

The replication factor changed from RF3 to RF2.

Question 9

Which TWO components are required in a HyperFlex cluster to provide both compute and storage functionality?

Accepted Answer

Storage Controller VM (SCVM). HyperFlex converged nodes provide both compute and storage. The controller VM (SCVM) manages storage, and the hypervisor (e.g., ESXi) runs workloads.

Answer

UCS Manager

Answer

CIMC

Answer

Witness VM

Question 10

An organization is deploying UCS Central to manage multiple UCS domains. Which THREE benefits does UCS Central provide over using individual UCS Managers?

Accepted Answer

Simplified firmware management across multiple domains.. UCS Central offers global policy management, centralized monitoring, and multi-domain firmware upgrades.

Answer

Automatic failover between Fabric Interconnects in different domains.

Answer

Direct management of blade chassis power supplies.

Question 11

A network engineer is configuring a UCS service profile for a B-series blade server. The goal is to allow the blade to be replaced without requiring reconfiguration of network identities. Which UCS feature enables this capability?

Accepted Answer

Stateless computing via service profile. Stateless computing abstracts hardware identities such as MAC addresses and WWNNs into the service profile, so a replacement blade inherits the same identities.

Answer

Fabric Interconnect failover

Answer

CIMC out-of-band management

Answer

UCS Central global policies

Question 12

An organization is deploying UCS B-series blades in a 5108 chassis connected to Fabric Interconnects A and B. Each blade has two vNICs. How should the vNICs be connected to the fabric to ensure maximum redundancy and bandwidth?

Accepted Answer

vNIC0 to FI A, vNIC1 to FI B, both active-active. For redundancy, vNICs should be connected to separate fabric interconnects (A and B) and active-active failover is recommended.

Answer

vNIC0 to FI A, vNIC1 to FI A via different ports

Answer

vNIC0 to FI A, vNIC1 to FI B with active-standby

Answer

Both vNICs connected to Fabric Interconnect A with active-standby failover

Question 13

A UCS administrator is creating a boot policy for a service profile that will be used for B-series blades. The requirement is to boot from a LUN on a SAN-attached storage array. Which boot order should be configured in the service profile boot policy?

Accepted Answer

SAN only with vHBA. Boot from SAN uses a vHBA to connect to a storage LUN. The boot policy should list the SAN target first.

Answer

Local disk and SAN with equal priority

Answer

PXE first, then SAN

Answer

Local disk first, then SAN

Question 14

A data center uses HyperFlex HX Data Platform with a 3-node cluster configured with replication factor 2 (RF2). One node fails permanently. What is the impact on data availability and cluster operation?

Accepted Answer

All data remains accessible but the cluster is degraded and requires a new node to restore RF2. With RF2, each data block is stored on two nodes. If one node fails, the remaining two nodes have all data, but the cluster becomes degraded. A new node must be added to restore redundancy.

Answer

Data is unavailable until the failed node is replaced

Answer

The witness VM takes over the failed node's storage role

Answer

The cluster automatically changes to RF3 to maintain protection

Question 15

An engineer is integrating a UCS C-series rack server into UCS Manager. The server is currently managed by CIMC. Which mode must be enabled on the C-series server to allow UCS Manager to discover and manage it?

Accepted Answer

UCS-Managed mode. UCS Manager can manage C-series servers in UCS-Managed mode, which requires the server to be in UCSM mode via CIMC.

Answer

Standalone mode

Answer

Cisco IMC Supervisor mode

Answer

Direct Connect mode
