350-601 Compute Practice Test 14 — 15 Questions

Question 1

Which of the following best describes stateless computing in Cisco UCS?

Accepted Answer

All server configuration is stored in the service profile, allowing any physical blade to assume the identity.. Stateless computing means that all configuration (BIOS, firmware, network, storage settings) is stored in the service profile on UCS Manager, not on the server. Thus, a failed blade can be replaced without reconfiguration.

Answer

VLANs and VSANs are not configured on the Fabric Interconnects.

Answer

Server state is saved to a local disk for recovery.

Answer

The server has no operating system installed.

Question 2

An engineer is deploying a HyperFlex cluster with three nodes using all-flash storage and replication factor 2 (RF2). What is the minimum number of nodes required to tolerate a single node failure?

Accepted Answer

3. With RF2, data is replicated to two nodes. If one node fails, the other node still holds a copy, so the cluster continues. However, for strict fault tolerance, a witness VM is needed to avoid split-brain. Three nodes with RF2 can tolerate one node failure.

Answer

2

Answer

5

Answer

4

Question 3

In a Cisco UCS Central environment, which feature enables global consistency of boot order and firmware policies across multiple UCS domains?

Accepted Answer

Global Service Profile Templates. UCS Central allows defining global service profile policies that can be applied to multiple UCS domains, ensuring consistency. Policies such as boot order, firmware, and BIOS can be created centrally and pushed to domains.

Answer

Cisco IMC Supervisor

Answer

Fabric Interconnect Interconnectivity

Answer

UCS Manager Backup and Restore

Question 4

Which UCS C-Series management mode allows the server to be managed as part of a UCS domain using service profiles, while still retaining the ability to use CIMC for direct out-of-band management?

Accepted Answer

UCS Managed mode. When a C-series server is adopted into UCS Manager, it can use service profiles but also retains its CIMC for direct management. This is the managed mode, as opposed to standalone (CIMC-only) mode.

Answer

Intersight Managed mode

Answer

Direct Connect mode

Answer

Cisco IMC Supervisor mode

Question 5

What is the purpose of the Cisco Integrated Management Controller (CIMC) for UCS C-Series rack servers?

Accepted Answer

To enable out-of-band management for remote server control. CIMC provides out-of-band management for rack servers, including remote KVM, virtual media, and firmware updates, independent of the host OS.

Answer

To provide high-speed data switching between servers

Answer

To manage storage arrays

Answer

To replace the need for a Fabric Interconnect

Question 6

In a HyperFlex cluster, what is the function of the cluster witness VM when replication factor 3 (RF3) is used?

Accepted Answer

It provides a quorum vote to prevent split-brain scenarios.. With RF3, data is replicated to three nodes. The witness VM is still needed for quorum and to prevent split-brain scenarios, especially when the cluster has an even number of nodes. For a 4-node cluster with RF3, a witness helps maintain availability.

Answer

It stores a third replica of all data to reduce storage requirements.

Answer

It handles storage replication tasks.

Answer

It serves as a backup node for failover.

Question 7

A UCS administrator needs to perform a firmware upgrade on a UCS B-Series blade server. Which management interface should be used to perform the upgrade remotely?

Accepted Answer

UCS Manager. UCS Manager provides centralized firmware management for all blades and FIs. The administrator can initiate firmware updates through UCS Manager GUI or CLI, which handles the upgrade process across the domain.

Answer

HyperFlex Connect

Answer

Cisco IMC Supervisor

Answer

CIMC of the blade server

Question 8

Which UCS B-Series chassis component provides the physical slot for a blade server?

Accepted Answer

Blade slot (bay). The UCS 5108 blade chassis has 8 half-width slots or 4 full-width slots. Blades are inserted into these slots and connect to the midplane.

Answer

IOM

Answer

Fabric Interconnect

Answer

Midplane

Question 9

When configuring a UCS service profile for a blade server that needs to boot from the local disk, which boot order setting is appropriate?

Accepted Answer

Set the boot order to local disk first, with no other boot devices.. To boot from local disk, the boot policy should list the local disk as the first boot device. Other devices can be secondary or disabled.

Answer

Enable PXE boot only.

Answer

Configure boot from CD/DVD as first device.

Answer

Set the boot order to SAN first, then local disk.

Question 10

In a HyperFlex cluster with hybrid nodes (HDD+SSD), which statement best describes the role of the SSD cache?

Accepted Answer

SSD acts as a write cache and read cache to accelerate I/O.. In HyperFlex, the SSD (or flash) in hybrid nodes serves as a cache for frequently accessed data, while the HDDs provide bulk storage. The HXDP uses SSDs for both caching and persistent storage in all-flash nodes.

Answer

SSD is used only for metadata storage.

Answer

SSD is used for long-term persistent storage, while HDD is used for caching.

Answer

SSD is not used; all data is stored on HDD.

Question 11

Which two are benefits of using Cisco UCS Central for multi-domain management? (Choose two.)

Accepted Answer

Allows creation of global service profile templates.. UCS Central provides centralized management of multiple UCS domains, enabling global policies and service profile templates. It also offers visibility and consistency across domains.

Answer

Eliminates the need for Fabric Interconnects.

Answer

Replaces the need for UCS Manager in each domain.

Answer

Enables direct CIMC management of all servers.

Question 12

Which three components are required for a basic Cisco UCS B-Series deployment? (Choose three.)

Accepted Answer

Blade Servers (B-Series). A basic UCS B-Series deployment includes Fabric Interconnects for network connectivity, a UCS 5108 chassis to house blades, and blade servers. UCS Manager is software that typically runs on the FIs.

Answer

UCS C-Series Rack Server

Answer

HyperFlex Cluster

Question 13

An engineer is designing a HyperFlex cluster with strict fault tolerance requirements. Which three considerations should be taken into account? (Choose three.)

Accepted Answer

A cluster witness VM is necessary to maintain quorum.. Replication factor (RF2 or RF3) determines data redundancy. The witness VM ensures quorum. Node count affects failure tolerance: with RF3, a 4-node cluster can tolerate two node failures; with RF2, a 3-node cluster can tolerate one failure.

Answer

A minimum of 5 nodes is required for RF3.

Answer

Hybrid nodes (HDD+SSD) offer better performance than all-flash.

Question 14

Which two methods can be used to boot a UCS C-Series rack server in a UCS Manager managed environment? (Choose two.)

Accepted Answer

Boot from SAN. In UCS Manager, a C-series server can boot from SAN via a SAN boot policy, or from local disk. PXE boot is also possible if configured in the service profile.

Answer

Boot from CD/DVD via KVM virtual media

Answer

Boot from NFS volume

Answer

Boot from USB flash drive inserted in the server

Question 15

A network engineer is configuring a UCS service profile for a new blade server. The requirement is that if the blade fails, it can be replaced with any blade of the same model without reconfiguration. Which UCS feature enables this capability?

Accepted Answer

Stateless computing. Stateless computing in UCS abstracts the hardware identity and configuration via service profiles, allowing a replacement blade to inherit the same configuration without manual reconfiguration.

Answer

VLAN configuration

Answer

RAID configuration

Answer

Firmware management policies
