350-601 Compute Practice Test 10 — 15 Questions

Question 1

A network administrator is planning a UCS C-Series rack server deployment. Which two statements correctly describe the integration modes with UCS Manager? (Choose two.)

Accepted Answer

In Direct Connect mode, the server must be connected to a Fabric Interconnect via a supported adapter.. Direct Connect mode connects servers directly to FI for management; IMC Supervisor mode manages via IMC Supervisor; standalone mode is independent.

Answer

In Cisco IMC Supervisor mode, the server is managed by the IMC Supervisor but can also be integrated into UCS Manager.

Answer

In Cisco IMC Supervisor mode, the server's CIMC is managed directly by UCS Manager.

Answer

Standalone mode allows the server to be managed by UCS Manager without any additional configuration.

Question 2

An engineer is configuring a HyperFlex cluster with three nodes. Which three components are required for a functional cluster? (Choose three.)

Accepted Answer

VMware vSphere or other supported hypervisor. HyperFlex requires at least three storage nodes for RF2, a vSphere cluster, and the HX Data Platform. A witness is needed for clusters with even number of nodes or for RF3? Actually for 3 nodes, witness is optional if RF2? Standard deployment: 3 nodes form a cluster; the witness is optional for 3 nodes but often recommended. The question expects the core components: storage nodes, vSphere, and HXDP. Witness is not mandatory for 3-node RF2 clusters.

Answer

A witness VM for quorum

Answer

Cisco UCS Manager for node management

Question 3

A UCS administrator needs to update the firmware on a remote rack server that is not reachable via the production network. Which two features of Cisco IMC can be used? (Choose two.)

Accepted Answer

Virtual media. CIMC provides out-of-band management; KVM console and virtual media can be used for firmware updates even if the OS network is down.

Answer

Syslog

Answer

SNMP traps

Answer

HTTP server integration

Question 4

A network engineer is configuring a UCS service profile for a B-series blade server that will boot from SAN. Which WWPN assignment method should be used to ensure the boot LUN remains accessible if the blade is replaced with another blade of the same type?

Accepted Answer

Assign a dynamic WWPN from a WWPN pool. Stateless computing in UCS relies on persistent WWPNs assigned from a WWPN pool, so when a blade is replaced, the new blade inherits the same WWPNs and can access the same storage LUNs without reconfiguration.

Answer

Set WWPN to the blade's serial number

Answer

Use the WWPN of the Fabric Interconnect port

Answer

Use the built-in WWPN of the mezzanine card

Question 5

What is the primary function of the Cisco Integrated Management Controller (CIMC) on UCS C-series rack servers?

Accepted Answer

To provide out-of-band management with KVM, virtual media, and remote firmware update. CIMC provides out-of-band management capabilities such as remote KVM, virtual media, and firmware updates, allowing administrators to manage the server independently of the host OS.

Answer

To manage the server's power and cooling via IPMI

Answer

To provide in-band management through the host OS

Answer

To integrate the rack server into UCS Manager fabric

Question 6

A company is designing a HyperFlex cluster with 4 nodes and wants to tolerate the failure of any two nodes simultaneously while maintaining data availability. Which replication factor and cluster configuration should be used?

Accepted Answer

RF3 with 4 nodes. HyperFlex HXDP uses replication factor (RF) to determine data copies. RF3 replicates data three times, allowing the cluster to survive up to two concurrent node failures (if the cluster has at least 3 nodes). With 4 nodes, RF3 meets the requirement.

Answer

RF3 with 3 nodes

Answer

RF2 with 5 nodes

Answer

RF2 with 4 nodes

Question 7

An engineer is configuring a UCS service profile for a blade server that will boot from local disk. However, the engineer wants to ensure that if the local disk fails, the server will attempt to boot from the SAN. Which boot policy setting should be used?

Accepted Answer

Set local disk as primary and SAN as secondary. UCS boot policies allow setting the boot order. To attempt local disk first and then SAN if local fails, the policy should have local disk as the primary and SAN as the secondary boot device.

Answer

Set the boot order to SAN first, then local disk

Answer

Configure local disk as the only boot device

Answer

Use PXE boot as the primary

Question 8

In a UCS domain, fabric interconnects are deployed in an end-host mode. What is a characteristic of this mode?

Accepted Answer

The FI uses N-Port Virtualization (NPV) to reduce the number of uplinks needed. End-host mode (also called N-Port Virtualization) allows the FI to act as a switch that presents server vNICs as if they were directly connected to the upstream network, simplifying VLAN/VXLAN configurations.

Answer

The FI must be configured with Spanning Tree Protocol

Answer

The FI supports only Fibre Channel traffic

Answer

The FI operates as a standard Layer 2 switch

Question 9

A data center administrator is using UCS Central to manage multiple UCS domains. They need to create a global service profile policy that defines the boot order for all blades across domains. What is the correct approach?

Accepted Answer

Define the boot policy as a global policy in UCS Central and associate it with service profiles. UCS Central allows creation of global policies that can be applied across domains. A global boot policy can be defined in UCS Central and then associated with service profiles in different UCS domains.

Answer

Use Cisco IMC Supervisor to manage boot policies across domains

Answer

Create a local boot policy in each UCS Manager and replicate manually

Answer

Configure the boot policy directly on the blade's CIMC

Question 10

Which type of I/O module (IOM) is installed in a UCS 5108 blade chassis to provide connectivity between blade servers and the fabric interconnects?

Accepted Answer

FEX (Fabric Extender). The IOMs in a 5108 chassis connect the blade midplane to the fabric interconnects via server ports. There are typically two IOMs for redundancy.

Answer

MDS switch

Answer

CIMC

Answer

Nexus 2000

Question 11

An organization wants to integrate their UCS C-series rack servers into an existing UCS Manager domain. Which mode should be used to achieve centralized management of the C-series servers through UCS Manager?

Accepted Answer

UCS Managed mode. C-series servers can be managed by UCS Manager when they are in UCS Managed mode, which requires the server to be connected via a Fabric Interconnect and have the appropriate license.

Answer

Direct Connect mode

Answer

Standalone mode

Answer

Cisco IMC Supervisor mode

Question 12

A HyperFlex cluster is configured with RF3 and has 6 nodes. If one node fails completely, how many nodes are still required to maintain data availability and cluster quorum?

Accepted Answer

4 nodes. With RF3, data is available as long as at least one copy remains. However, cluster quorum requires more than half of the nodes to be operational. For a 6-node cluster, quorum is 4 nodes (majority). After 1 failure, 5 nodes remain, which is >3, so quorum is maintained. However, the minimum to keep data available with RF3 is 3 nodes (since 3 copies exist, losing one still leaves 2). But cluster quorum is the stricter requirement: with 6 nodes, quorum is 4. So after 1 failure, 5 nodes are still up, satisfying quorum.

Answer

3 nodes

Answer

5 nodes

Answer

6 nodes

Question 13

An engineer is configuring a UCS service profile for a blade server that will use FCoE to connect to a Fibre Channel SAN. What must be configured in the service profile to support FCoE traffic?

Accepted Answer

Configure the vNIC with FCoE personality and specify the FCoE VLAN. To carry FCoE traffic, the vNIC must be configured to use the FCoE VLAN and have the FCoE personality enabled. This allows the adapter to parse FCoE frames.

Answer

Assign a WWPN to the vNIC

Answer

Enable the FCoE flag on the vHBA

Answer

Set the vNIC to use the native VLAN for FCoE

Question 14

What is the purpose of a cluster witness VM in a HyperFlex cluster?

Accepted Answer

To act as a tie-breaker for quorum in cluster splits. The witness VM is used to achieve quorum in a two-node cluster (or to maintain quorum in case of network partitions). It is a lightweight VM that participates in cluster decision-making.

Answer

To host the HyperFlex management interface

Answer

To provide additional storage capacity

Answer

To provide compute resources for the cluster

Question 15

An administrator needs to replace a faulty blade server in a UCS chassis. The blade is associated with a service profile that has a persistent WWPN pool. What is the correct procedure to maintain stateless computing?

Accepted Answer

Remove the faulty blade, insert the new blade, and auto-associate the service profile. UCS stateless computing allows a blade replacement without reconfiguration by simply disassociating the service profile from the faulty blade, removing the blade, inserting the new blade, and re-associating the same service profile. The WWPNs from the pool are retained.

Answer

Replace the blade and delete the old service profile to create a new one

Answer

Replace the blade and update the WWPN pool to match the new hardware

Answer

Replace the blade and manually reconfigure the service profile with new WWPNs
