350-601 Compute Practice Test 1 — 15 Questions

Question 1

A network engineer is configuring a new UCS B-series blade server. The engineer wants the server to automatically inherit network and storage settings without manual configuration when replaced. Which UCS technology enables this capability?

Accepted Answer

Service profile template. Service profile templates in Cisco UCS Manager allow administrators to define a reusable configuration for network and storage settings. When a server fails or is replaced, the template is applied to the new blade, automatically inheriting all settings without manual intervention. This capability is central to UCS's stateless computing model, where hardware identity and policies are abstracted from the physical server.

Answer

Fabric Interconnect failover

Answer

Cisco IMC Supervisor

Answer

Cisco UCS Manager

Question 2

An organization has deployed a 4-node HyperFlex cluster with all-flash storage and replication factor 3 (RF3). One node fails. How many nodes are required to remain operational for the cluster to continue serving data without interruption?

Accepted Answer

3. For RF3, data is replicated three times. With 4 nodes, if one fails, three remain, which still have all data copies. The cluster remains operational.

Question 3

A data center administrator is configuring a Cisco UCS C-series rack server in standalone mode using CIMC. Which interface must be used to mount an ISO image for OS installation over the network?

Accepted Answer

CIMC web interface (KVM or Virtual Media). CIMC provides virtual media capabilities, allowing remote mounting of ISO images via KVM or virtual media session.

Answer

Cisco IMC Supervisor

Answer

UCS Manager GUI

Answer

UCS Central

Question 4

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?

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 5

An engineer needs to deploy a stateless UCS B-series blade with a boot from SAN configuration. Which components must be defined in the service profile to achieve this?

Accepted Answer

vHBA and WWPN. For a stateless UCS B-series blade with boot from SAN, the service profile must define a vHBA (virtual Host Bus Adapter) with a WWPN (World Wide Port Name). The WWPN is used by the SAN fabric to identify the server and present the correct LUN for booting, enabling stateless boot without local storage. iSCSI and MAC addresses are irrelevant for Fibre Channel SAN boot, and local disk configuration is not used in a stateless boot-from-SAN design.

Answer

iSCSI vNIC and IQN

Answer

vNIC and MAC address

Answer

Local disk configuration

Question 6

A UCS Central administrator is creating a global service profile policy that applies to multiple UCS domains. The policy must include boot order settings. What is the recommended approach to ensure consistency across domains?

Accepted Answer

Use UCS Central to create a global boot policy and assign it to service profiles. UCS Central allows creation of global policies that are applied to service profiles in multiple domains, ensuring consistency.

Answer

Rely on default boot policy

Answer

Define the boot order directly in the service profile template

Answer

Create a local boot policy in each UCS domain

Question 7

Which component connects a UCS 5108 blade chassis to the Fabric Interconnects?

Accepted Answer

IOM (Input/Output Module). IOMs (Input/Output Modules) in the chassis provide connectivity to the FIs.

Answer

CIMC

Answer

Midplane

Answer

FEX (Fabric Extender)

Question 8

A UCS C-series rack server is being integrated into UCS Manager using direct connect mode. Which statement about management connectivity is true?

Accepted Answer

The server is managed by UCS Manager through a dedicated management uplink. In direct connect mode, the C-series server is managed through UCS Manager via a dedicated management connection.

Answer

The server's management traffic passes through the Fabric Interconnects

Answer

The server must be configured with IMC Supervisor

Answer

The server must use CIMC for management and cannot be managed by UCS Manager

Question 9

In a HyperFlex cluster with replication factor 2 (RF2), what is the minimum number of nodes required to sustain a single node failure?

Accepted Answer

3. In a HyperFlex cluster with replication factor 2 (RF2), each data block is stored on two different nodes. To survive a single node failure, the cluster must have at least three nodes: two nodes to hold the two replicas of the data, and a third node to provide a witness (or tie-breaker) for cluster quorum and to ensure data availability during the failure. With only two nodes, a single failure would leave only one replica, violating the RF2 requirement and potentially causing data loss or cluster unavailability.

Question 10

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 11

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

Accepted Answer

To break ties in cluster quorum decisions. In a HyperFlex cluster, the witness VM provides a tie-breaking vote for cluster quorum decisions when the cluster experiences a network partition or node failure. It ensures that the surviving side can maintain a majority and continue operating, preventing split-brain scenarios where both sides would independently write data.

Answer

To act as a management node for the cluster

Answer

To provide additional storage capacity

Answer

To replicate data across sites

Question 12

A UCS B-series blade has two vHBAs configured for Fibre Channel SAN connectivity. The engineer wants to ensure that if one vHBA fails, the other can take over. What must be configured in the service profile?

Accepted Answer

vHBA failover policy. vHBA failover policy allows a secondary vHBA to assume the WWPN of the primary if it fails.

Answer

FC zone configuration

Answer

Boot policy

Answer

vNIC failover policy

Question 13

An organization uses UCS Central to manage multiple UCS domains. They need to create a global VLAN policy that applies to all domains. How is this achieved?

Accepted Answer

Create a global VLAN policy in UCS Central and apply it to the service profile templates. UCS Central provides centralized management for multiple UCS domains. A global VLAN policy created in UCS Central is automatically propagated to all managed UCS domains, ensuring consistent VLAN definitions across the infrastructure. Applying this policy to service profile templates enforces the VLAN configuration on all associated service profiles, eliminating the need for per-domain configuration.

Answer

Use Cisco IMC Supervisor to distribute VLANs

Answer

Configure VLANs on the Fabric Interconnects directly

Answer

Define the VLAN policy locally in each UCS domain

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

In a UCS B-series chassis, which component provides the management connectivity between the blades and the Fabric Interconnects?

Accepted Answer

IOM (Input/Output Module). The Input/Output Module (IOM) in a UCS B-series chassis provides the management connectivity between the blades and the Fabric Interconnects. It aggregates all blade traffic, including management traffic (such as CIMC communications), and forwards it to the Fabric Interconnects over the chassis backplane. Without the IOM, the blades would have no path to the Fabric Interconnects for management or data-plane operations.

Answer

CIMC

Answer

UCS Manager

Answer

Blade midplane
