350-601 Practice Test 14 — 15 Questions

Question 1

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?

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

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 2

An engineer is deploying a HyperFlex cluster with all-flash nodes and replication factor 3. What is the minimum number of converged nodes required for the cluster to be fully operational?

Accepted Answer

3 nodes. HyperFlex clusters require at least three converged nodes for RF3 to maintain data redundancy and quorum.

Answer

4 nodes

Answer

2 nodes

Answer

5 nodes

Question 3

Which component in a UCS B-series chassis provides the connectivity between blade servers and the Fabric Interconnects?

Accepted Answer

I/O Module (IOM). I/O Modules (IOMs) in the chassis connect blades to the Fabric Interconnects via server ports.

Answer

Fabric Interconnect

Answer

Midplane

Answer

Fabric Extender (FEX)

Question 4

Which TWO statements accurately describe Cisco UCS service profiles? (Choose two.)

Accepted Answer

They can be created from templates to ensure consistency.. Service profiles abstract hardware and are template-based for consistency.

Answer

They are bound to a specific physical blade and cannot be reassigned.

Answer

They require individual configuration for each server without reuse.

Answer

They are used only for B-series blades, not C-series.

Question 5

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 6

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 7

A UCS C-series server is deployed in standalone mode and managed via CIMC. The administrator needs to mount an ISO image for OS installation. Which CIMC feature should be used to remotely attach the ISO?

Accepted Answer

Virtual media. CIMC provides virtual media functionality, allowing mounting ISO images as virtual CD/DVD drives over the network.

Answer

KVM console

Answer

Serial over LAN

Answer

Remote firmware update

Question 8

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 9

A company is deploying UCS C-Series rack servers and wants to integrate them into UCS Manager for centralized management. The servers are currently managed individually via CIMC. Which integration mode must be configured on the C-Series servers to allow UCS Manager to discover and manage them?

Accepted Answer

UCS Managed mode. C-Series servers can be integrated into UCS Manager by enabling UCS Managed mode in the server's CIMC. This allows the FI to discover and manage the server as part of the UCS domain.

Answer

IMC Supervisor mode

Answer

Direct connect mode

Answer

Standalone mode

Question 10

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 11

In a HyperFlex cluster configured with replication factor 2 (RF2), a storage node fails. What is the impact on data availability?

Accepted Answer

Data remains available, but the cluster is degraded and cannot tolerate another node failure until repaired.. With RF2, data is replicated across two nodes. If one node fails, the data remains available on the other node. However, the cluster enters a degraded state until the node is replaced and data is re-replicated.

Answer

Data is lost because only one copy remains.

Answer

The cluster stops serving data until the failed node is replaced.

Answer

The cluster automatically switches to RF3 to maintain redundancy.

Question 12

A data center network uses MST with multiple instances. Different VLANs are mapped to different MST instances to utilize multiple spanning tree paths. Which MST parameter must be identical on all switches in the same region to ensure proper operation?

Accepted Answer

MST region name and revision number. In MST, all switches within the same region must agree on the region name and revision number to form a consistent MST region. If these parameters differ, switches will treat each other as being in different regions, causing the MST instances to be recalculated as separate CST (Common Spanning Tree) regions, which can lead to suboptimal or broken load balancing across VLANs.

Answer

Port path cost

Answer

Bridge priority

Answer

Max age timer

Question 13

A data center administrator is deploying a HyperFlex cluster and needs to choose between hybrid (HDD+SSD) and all-flash node configurations. Which two factors should be considered when making this decision? (Choose two.)

Accepted Answer

Hybrid nodes are more cost-effective for large storage capacities.. Hybrid nodes offer lower cost per terabyte but lower performance for write-intensive workloads. All-flash nodes provide higher performance and lower latency but at a higher cost. Both support replication factors and clustering.

Answer

All-flash nodes support higher replication factors than hybrid nodes.

Answer

Hybrid nodes require more power and cooling than all-flash nodes.

Answer

Hybrid nodes cannot be used in a cluster with all-flash nodes.

Question 14

Which Cisco UCS feature allows a failed blade server to be replaced with a new one without any reconfiguration, because all identity and configuration information is abstracted?

Accepted Answer

Service profile. Stateless computing via service profiles abstracts the blade's identity (MAC, WWPN, UUID) so that replacing the hardware does not require reconfiguration.

Answer

Firmware auto-sync

Answer

Fabric failover

Answer

Dynamic vNIC connection policy

Question 15

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
