350-601 Practice Test 46 — 15 Questions

Question 1

Which HyperFlex node type offers the best performance for all-flash workloads and does not include HDDs?

Accepted Answer

All-flash. HyperFlex supports hybrid nodes (HDD+SSD cache) and all-flash nodes (SSD only). All-flash nodes provide higher performance and no HDDs.

Answer

Compute-only

Answer

Hybrid HDD/SSD

Answer

Storage-only

Question 2

Which RAID level provides both striping and mirroring for high performance and fault tolerance?

Accepted Answer

RAID 10. RAID 10 (also known as RAID 1+0) combines mirroring and striping to provide both high performance and redundancy.

Answer

RAID 0

Answer

RAID 5

Answer

RAID 6

Question 3

A Cisco MDS switch is configured with a VSAN and the administrator needs to assign a Fibre Channel port to this VSAN. Which command should be used in interface configuration mode to assign the port to VSAN 10?

Accepted Answer

switchport vsan 10. The 'switchport vsan' command is used to assign a Fibre Channel interface to a specific VSAN.

Answer

vsan database vsan 10

Answer

switchport mode vsan 10

Answer

vsan 10

Question 4

A Cisco MDS switch is being configured for FCoE. Which three DCB components are required for lossless Ethernet operation? (Choose three.)

Accepted Answer

DCBX (Data Center Bridging Exchange). PFC, DCBX, and ETS are the three core DCB features required for FCoE.

Answer

FIP (FCoE Initialization Protocol)

Answer

iSCSI

Question 5

Which TWO statements correctly describe the benefits of thin provisioning in a storage array?

Accepted Answer

It allows over-provisioning of logical capacity beyond physical capacity. Thin provisioning allows over-allocation of storage capacity, reducing waste, and enables on-demand allocation of physical storage as data is written.

Answer

It eliminates the need for RAID protection

Answer

It improves performance by pre-allocating all storage upfront

Answer

It simplifies disaster recovery by replicating only allocated blocks

Question 6

A storage administrator is configuring synchronous replication between two storage arrays over a Fibre Channel link. Which characteristic best describes synchronous replication?

Accepted Answer

The write is acknowledged to the host only after data is written to both primary and secondary.. Synchronous replication writes data to both the primary and secondary storage before acknowledging the write to the host, ensuring zero data loss but increasing latency.

Answer

Data is written to the primary and then asynchronously to the secondary, reducing latency.

Answer

The secondary storage is used only for backup and is not actively updated.

Answer

Data is written to the primary and later replicated based on a schedule.

Question 7

Which RAID level provides striping with parity and can tolerate a single disk failure while offering higher storage efficiency than RAID 1?

Accepted Answer

RAID 5. RAID 5 uses block-level striping with distributed parity, allowing recovery from a single disk failure with good storage efficiency (one disk worth of parity).

Answer

RAID 0

Answer

RAID 6

Answer

RAID 1

Question 8

A storage engineer is planning a disaster recovery solution that requires zero data loss in the event of a site failure. The storage arrays support both synchronous and asynchronous replication. Which replication type should be chosen to meet the requirement?

Accepted Answer

Synchronous replication. Synchronous replication writes data to both local and remote storage before acknowledging the write, ensuring zero data loss (RPO=0). Asynchronous replication may have some data loss depending on the lag.

Answer

Asynchronous replication

Answer

Snapshot-based replication

Answer

Thin provisioning

Question 9

Which THREE components are required to implement Fibre Channel over Ethernet (FCoE) in a data center?

Accepted Answer

Converged Network Adapter (CNA). FCoE requires a Converged Network Adapter (CNA) that supports both Ethernet and FCoE, DCB-enabled switches to provide lossless Ethernet (PFC, DCBX, ETS), and FCoE initialisation (FIP) to establish virtual links.

Answer

Fibre Channel switch with E-port

Answer

iSCSI initiator software

Question 10

A storage administrator is configuring a VSAN on a Cisco MDS switch. After creating the VSAN, what is the next step to ensure that the ports can communicate within that VSAN?

Accepted Answer

Assign ports to the VSAN. After creating the VSAN, the ports must be assigned to it. This is done by configuring the port VSAN membership.

Answer

Enable NPV mode on the switch

Answer

Enable FCoE

Answer

Configure zoning

Question 11

Which Fibre Channel address component identifies the port on a storage target?

Accepted Answer

WWPN. WWPN (World Wide Port Name) is a globally unique 64-bit identifier assigned to each Fibre Channel port.

Answer

WWNN

Answer

FCID

Answer

VSAN ID

Question 12

An engineer is configuring iSCSI CHAP authentication between an initiator and a target. The initiator has a CHAP username and secret configured. What must be configured on the target?

Accepted Answer

The same username and secret as the initiator.. For one-way CHAP, the target must have the same username and secret to authenticate the initiator. For mutual CHAP, additional configuration is needed, but the question implies one-way CHAP.

Answer

A different username and secret.

Answer

No CHAP configuration is needed on the target.

Answer

Only the secret, no username.

Question 13

Which THREE of the following are required to configure Fibre Channel PortChannels on Cisco MDS switches?

Accepted Answer

All member ports must be in the same VSAN. Fibre Channel PortChannels require that all member ports have the same speed and configuration, and that they are on the same switch. They can be used with E-ports for ISL trunking.

Answer

NPV mode must be enabled on the switch

Answer

All member ports must be configured as F-ports

Question 14

An engineer is configuring FCoE on a Cisco UCS Fabric Interconnect. The network requires lossless Ethernet to support FCoE traffic. Which Data Center Bridging (DCB) feature must be enabled first to ensure no frames are dropped due to congestion?

Accepted Answer

PFC. PFC (Priority Flow Control) is the DCB mechanism that provides lossless Ethernet for FCoE.

Answer

ETS

Answer

DCBX

Answer

FIP

Question 15

An engineer is implementing storage virtualization with thin provisioning on a Pure Storage array. Which three benefits does thin provisioning provide? (Choose three.)

Accepted Answer

Ability to over-allocate storage. Thin provisioning allows over-allocation, reduces upfront capacity costs, and improves storage utilization by allocating space on demand.

Answer

Simplified snapshot management

Answer

Guaranteed performance isolation
