350-601 Storage Network Practice Test 13 — 15 Questions

Question 1

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 2

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 3

Which iSCSI authentication method provides mutual authentication between initiator and target using a shared secret?

Accepted Answer

CHAP. CHAP (Challenge Handshake Authentication Protocol) can be configured for one-way or mutual authentication. Mutual CHAP authenticates both sides using a shared secret.

Answer

Kerberos

Answer

IPsec

Answer

RADIUS

Question 4

What is the purpose of jumbo frames in an iSCSI storage network?

Accepted Answer

To increase throughput by reducing protocol overhead. Jumbo frames (MTU 9000) reduce overhead by allowing larger payloads per packet, improving throughput and CPU efficiency for iSCSI traffic.

Answer

To reduce latency

Answer

To provide authentication

Answer

To enable flow control

Question 5

In a Fibre Channel fabric using NPV mode, what is the role of the NP-port on the edge switch?

Accepted Answer

It connects to a core switch's F-port and proxies host logins. The NP-port (N_Port Proxy) on the edge switch behaves like an N-port but proxies the login for multiple hosts through the core switch's F-port, reducing the number of domain IDs needed.

Answer

It is used to connect to storage arrays

Answer

It is used for VSAN trunking

Answer

It acts as an E-port for ISL connectivity

Question 6

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 7

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 8

Which TWO statements correctly describe active zone sets in a Cisco MDS Fibre Channel fabric?

Accepted Answer

The active zone set is propagated to all switches in the fabric. An active zone set is the set of zones that are enforced in the fabric. Only one zone set can be active at a time, and it is propagated to all switches in the fabric.

Answer

Zones within the active zone set can be selectively deactivated

Answer

The active zone set is stored in the running configuration only

Answer

Multiple zone sets can be active simultaneously

Question 9

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 10

Which TWO statements correctly describe the difference between synchronous and asynchronous replication?

Accepted Answer

Asynchronous replication has lower impact on application performance. Synchronous replication has zero RPO but can impact performance due to latency, while asynchronous replication has a lower performance impact but may have some data loss (nonzero RPO).

Answer

Asynchronous replication requires dedicated links

Answer

Synchronous replication is more tolerant of high latency links

Answer

Asynchronous replication guarantees zero data loss

Question 11

Which FC port type is used for end-device connection in Fibre Channel fabric, and is typically found on a host bus adapter?

Accepted Answer

N-port. N-port is the standard port type for end devices in Fibre Channel.

Answer

NP-port

Answer

E-port

Answer

F-port

Question 12

A Cisco MDS switch is connected to another MDS via a Fibre Channel link. The two switches need to carry traffic for multiple VSANs over a single physical link. Which feature should be configured?

Accepted Answer

EISL trunking. EISL (Enhanced ISL) allows multiple VSANs to be trunked over a single ISL.

Answer

NPV mode

Answer

PortChannel

Answer

VSAN-based zoning

Question 13

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 14

A storage administrator wants to isolate two Fibre Channel fabrics on the same physical switch infrastructure. Which technology should be used to achieve this isolation similar to VLANs in Ethernet?

Accepted Answer

VSANs. VSANs provide isolation in Fibre Channel networks analogous to VLANs.

Answer

PortChannels

Answer

Zoning

Answer

NPV

Question 15

Which Fibre Channel addressing component identifies a specific port on a host or storage device uniquely in the fabric?

Accepted Answer

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

Answer

WWNN

Answer

VSAN ID

Answer

FCID
