350-601 Compute Practice Test 15 — 15 Questions

Question 1

An engineer is designing a UCS environment for a virtualized workload that requires high availability. Two Fabric Interconnects are deployed in an active-active configuration. Which statement about the role of the Fabric Interconnects is accurate?

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

Accepted Answer

Both FIs are active and can forward traffic, but only one manages the chassis at a time.. In a UCS system with two Fabric Interconnects in active-active mode, both FIs forward data traffic simultaneously. However, for management functions such as chassis discovery and firmware management, only one FI acts as the primary management controller at a time, while the other is standby. This ensures consistency and avoids conflicts in managing the chassis and blades.

Answer

The FIs are used only for management traffic and not for data traffic.

Answer

One FI acts as primary and the other as secondary, forwarding traffic only if the primary fails.

Answer

The FIs operate in a standalone mode and must be configured independently.

Question 2

A UCS B-Series chassis has four IOM modules installed. The chassis is connected to two Fabric Interconnects. How many uplink connections are typically used from each IOM to the Fabric Interconnects to ensure full bandwidth redundancy?

Accepted Answer

Two uplinks per IOM to each FI. Each IOM has four uplink ports (two per fabric). To achieve full bandwidth and redundancy, typically all four uplinks are used (two to FI-A and two to FI-B).

Answer

One uplink from the chassis to each FI

Answer

Four uplinks per IOM to a single FI

Answer

One uplink per IOM to each FI

Question 3

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 4

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 5

An engineer is configuring a UCS service profile for a blade server that will boot from SAN. The storage is connected via FC SAN. Which policy must be included in the service profile to define the WWPNs for the HBAs?

Accepted Answer

SAN connectivity policy. To boot from SAN, the service profile must include a SAN connectivity policy that defines the WWPNs (World Wide Port Names) for the vHBAs. This policy assigns WWPNs from a pool or statically.

Answer

Network control policy

Answer

Boot policy

Answer

vNIC placement policy

Question 6

Which management interface is used for out-of-band management of UCS C-Series rack servers, providing features like KVM, virtual media, and remote firmware upgrade?

Accepted Answer

CIMC. The Cisco Integrated Management Controller (CIMC) is the out-of-band management interface for UCS C-Series servers, offering KVM, virtual media, and remote firmware management.

Answer

Cisco IMC Supervisor

Answer

UCS Central

Answer

UCS Manager

Question 7

A company plans to deploy multiple UCS domains across different geographical locations. They want a single pane of glass to manage service profiles globally. Which Cisco solution should be used?

Accepted Answer

UCS Central. UCS Central provides centralized management of multiple UCS domains, enabling global service profile policies and management across domains.

Answer

UCS Manager

Answer

HyperFlex Connect

Answer

Cisco IMC Supervisor

Question 8

An engineer is deploying a HyperFlex cluster and needs to ensure that if a disk fails in a hybrid node, the system can rebuild the data from parity. Which RAID configuration is required on the disk controller for the cache SSD and HDDs in a HyperFlex hybrid node?

Accepted Answer

RAID 0 for SSD and RAID 5 for HDDs. In HyperFlex hybrid nodes, the cache SSD is configured as RAID 0 (striping without parity) for performance, while the HDDs can be configured as RAID 5 or RAID 6 for redundancy. For the SSD cache, RAID 0 is typically used because data is replicated at the cluster level.

Answer

RAID 6 for SSD and RAID 0 for HDDs

Answer

RAID 10 for both SSD and HDDs

Answer

RAID 1 for SSD and RAID 5 for HDDs

Question 9

In UCS service profile templates, when you update the template, how do the changes propagate to the service profiles derived from it?

Accepted Answer

Changes are automatically applied to all derived service profiles immediately.. When a service profile is created from a template, it can be set to update automatically when the template changes, or manually. The default behavior is that changes are propagated automatically unless the profile is set to manual update.

Answer

Changes are applied only if the service profile is not associated with a server.

Answer

Changes are applied only during server reboot.

Answer

Changes must be manually applied to each derived service profile.

Question 10

A UCS blade server has two vHBAs configured. The storage array is connected to both Fabric Interconnects. Which multipathing configuration should be used on the host to provide path redundancy without needing additional storage ports?

Accepted Answer

Active/active multipathing. With two vHBAs connected to two separate FIs, the host can use active/active multipathing (e.g., ALUA or symmetric) to utilize both paths simultaneously for redundancy and load balancing.

Answer

Active/passive multipathing

Answer

Single path with failover

Answer

Round-robin I/O scheduling

Question 11

A UCS C-Series server is initially deployed in standalone mode using CIMC. Later, the server is moved into a UCS domain managed by UCS Manager. What must be done to the CIMC configuration to allow UCS Manager to take control?

Accepted Answer

Change the CIMC management mode from standalone to UCS-managed.. To integrate a standalone C-Series server into UCS Manager, the server must be reset to factory defaults (or the management mode changed to UCS-managed) and then discovered by the Fabric Interconnect.

Answer

Disable the CIMC interface and use only UCS Manager.

Answer

Update the CIMC firmware to the latest version.

Answer

Install a Cisco VIC adapter in the server.

Question 12

In a HyperFlex cluster with replication factor 3 (RF3), a node fails completely. The cluster has five nodes. What is the minimum number of nodes that must be operational for the cluster to continue serving data without interruption?

Accepted Answer

3 nodes. With RF3, data is replicated on three nodes. If one node fails, the cluster can continue serving data as long as at least three nodes (including the failed node's replicas on other nodes) are available. Since the cluster has five nodes, even with one failure, four nodes remain, which is sufficient.

Answer

4 nodes

Answer

5 nodes

Answer

2 nodes

Question 13

Which component in a UCS 5108 blade chassis provides the connectivity between the blade servers and the Fabric Interconnects?

Accepted Answer

I/O Module (IOM). The I/O Module (IOM) in the UCS 5108 chassis provides the uplink ports that connect to the Fabric Interconnects and the downlink ports that connect to the blade servers.

Answer

Chassis management controller (CMC)

Answer

Midplane

Answer

Fabric Extender (FEX)

Question 14

An engineer is configuring a UCS service profile for a blade that will boot from local disk. The blade has two SAS drives configured as a RAID 1 mirror. Which policy is required to specify the local disk boot order?

Accepted Answer

Boot policy. The boot policy in a service profile defines the boot order and boot devices. For local disk boot, the boot policy must list the local disk as the primary boot device.

Answer

SCSI policy

Answer

Disk policy

Answer

Storage policy

Question 15

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.
