350-601 Practice Test 12 — 15 Questions

Question 1

In a dual-fabric UCS environment, Fabric Interconnect A and Fabric Interconnect B provide redundancy. If Fabric Interconnect A fails, what happens to the traffic from servers using vNICs assigned to Fabric A?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Traffic is lost until Fabric A is restored. vNICs assigned to Fabric A are pinned to FI-A. If FI-A fails, those vNICs lose connectivity unless failover is configured to Fabric B.

Answer

Traffic is rerouted through the chassis IOM

Answer

Traffic is load-balanced between both fabrics

Answer

Traffic automatically fails over to Fabric B

Question 2

Which type of UCS service profile allows an administrator to define a configuration that can be used as a starting point for multiple servers, with each server potentially having unique settings?

Accepted Answer

Service profile template. A service profile template is used to define a base configuration that can be instantiated into multiple service profiles, each of which can be customized.

Answer

Initial service profile

Answer

Derived service profile

Answer

Base service profile

Question 3

An organization is deploying UCS C-series rack servers in standalone mode. Which two management capabilities are available through Cisco IMC? (Choose two.)

Accepted Answer

KVM console access. Cisco IMC provides KVM console and virtual media mounting, as well as remote firmware upgrade. These are common out-of-band management features.

Answer

UCS Manager integration

Answer

HyperFlex cluster management

Answer

Fibre Channel zoning

Question 4

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 5

An engineer is deploying UCS B-series blades in a 5108 chassis connected to a pair of Fabric Interconnects. To ensure high availability, each blade's vNICs must be pinned to both FIs. Which configuration method should be used in the service profile to achieve this?

Accepted Answer

Create a vNIC placement policy that assigns one vNIC to Fabric A and another vNIC to Fabric B, both without failover.. In UCS Manager, the vNIC placement policy determines how vNICs are assigned to fabric interconnects. Selecting 'fabric failover' allows a vNIC to fail over to the other FI, but for active-active use, multiple vNICs are needed. The correct approach is to use a vNIC placement policy that assigns each vNIC to a specific fabric without failover, combined with proper fabric pinning in the LAN connectivity policy.

Answer

Configure each vNIC with fabric failover enabled, then assign the vNICs to the same fabric.

Answer

Use the default vNIC template which automatically assigns vNICs to both fabrics.

Answer

Enable fabric failover on the uplink ports of the Fabric Interconnects.

Question 6

A data center administrator is designing a HyperFlex cluster for a virtualized environment. The cluster must be able to tolerate the failure of any two nodes. Which two configuration choices are required? (Choose two.)

Accepted Answer

Minimum of 5 nodes. To tolerate two node failures, the cluster must have at least 5 nodes (with RF3, quorum requires >50% of total nodes; with 5 nodes, quorum is 3, and losing 2 leaves 3, maintaining quorum). RF3 replicates data three times, ensuring data remains available even after two failures.

Answer

Cluster witness VM

Answer

Minimum of 4 nodes

Answer

Replication factor RF2

Question 7

A UCS administrator wants to deploy a Cisco UCS C-Series rack server in a UCS Manager-managed environment. The server is currently in standalone mode using CIMC. Which step is required to integrate the C-Series server into UCS Manager?

Accepted Answer

Adopt the server into UCS Manager by reinitializing CIMC and connecting it to the Fabric Interconnects.. To integrate a C-series rack server into UCS Manager, the server must be adopted by the UCS Manager, which involves reinitializing the CIMC to connect to the Fabric Interconnects. This enables management through UCS Manager with service profiles.

Answer

Configure the server in direct connect mode with the Fabric Interconnects.

Answer

Install an I/O Module in the rack server to enable Fabric Interconnect connectivity.

Answer

Use Cisco IMC Supervisor to connect the server to UCS Manager.

Question 8

An administrator is configuring a HyperFlex cluster with 4 nodes. To ensure data availability in the event of two simultaneous node failures, what replication factor should be configured?

Accepted Answer

RF3. With RF3, each data block is stored on three nodes, allowing the cluster to survive two node failures (provided the witness is available for quorum).

Answer

RF2

Answer

RF4

Answer

RF1

Question 9

A data center administrator needs to manage multiple UCS domains from a single pane of glass, including the ability to push global service profile policies. Which Cisco management tool should be used?

Accepted Answer

Cisco UCS Central. Cisco UCS Central provides centralized management for multiple UCS domains, enabling global policies and templates.

Answer

Cisco UCS Director

Answer

Cisco IMC Supervisor

Answer

Cisco UCS Manager

Question 10

In a UCS 5108 chassis, which component provides the connectivity between the blade servers and the Fabric Interconnects?

Accepted Answer

IOM (FEX). The IOM (Input/Output Module) in the chassis connects to the Fabric Interconnects via server ports and provides connectivity to each blade slot.

Answer

Midplane

Answer

Chassis management controller

Answer

Fabric Interconnect

Question 11

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 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 PXE boot for a UCS B-series blade. The blade's vNIC is associated with a VLAN that has no IP helper address configured. What is required to allow the blade to obtain an IP address from a DHCP server on a different subnet?

Accepted Answer

Add an IP helper address on the VLAN interface in the upstream switch. PXE boot requires DHCP. Without IP helper, broadcast DHCP requests cannot cross subnets. A DHCP relay or IP helper is needed.

Answer

Configure a static IP address in the service profile

Answer

Enable DHCP snooping on the Fabric Interconnect

Answer

Use a local DHCP server on the same VLAN

Question 14

A UCS C-series server is deployed in a standalone environment. The administrator needs to update the server's firmware remotely. Which CIMC feature should be used?

Accepted Answer

Firmware Update page in CIMC. CIMC provides remote firmware update capability through its web interface or CLI.

Answer

Virtual KVM

Answer

Virtual Media

Answer

UCS Manager

Question 15
