350-601 Storage Network Practice Test 2 — 15 Questions

Question 1

A storage administrator is configuring a new Fibre Channel fabric using Cisco MDS switches. The edge switches must connect to the core without participating in the full routing domain to conserve domain IDs. Which Fibre Channel feature should be configured on the edge switches?

Accepted Answer

NPV mode. N-Port Virtualization (NPV) mode allows an edge switch to connect to a core switch without consuming a Fibre Channel domain ID, scaling the fabric while reducing administrative overhead.

Answer

PortChannels

Answer

VSANs

Answer

EISL trunking

Question 2

An engineer is configuring zoning on a Cisco MDS switch. The requirement is to ensure that only the storage array ports with specific WWPNs can access the host initiators. Which zoning approach should be used to enforce this policy regardless of physical port changes?

Accepted Answer

Hard zoning by WWPN. Hard zoning based on WWPN ensures that membership is tied to the device's World Wide Port Name, so changes in physical connectivity do not affect the zone membership.

Answer

Soft zoning by WWPN

Answer

Soft zoning by port ID

Answer

Hard zoning by domain/port

Question 3

Which Fibre Channel port type is used to connect a host bus adapter (HBA) to a Fibre Channel switch in a point-to-point topology?

Accepted Answer

N-port. An N-port (Node port) is used on the host side, and an F-port (Fabric port) is used on the switch side. The question asks for the host side port type.

Answer

E-port

Answer

F-port

Answer

NP-port

Question 4

In a Fibre Channel over Ethernet (FCoE) deployment, which Data Center Bridging (DCB) feature is responsible for preventing frame loss due to congestion and ensuring the lossless behavior required for FCoE traffic?

Accepted Answer

Priority Flow Control (PFC). Priority Flow Control (PFC) is a per-priority pause mechanism that creates lossless links for specific traffic classes such as FCoE.

Answer

Data Center Bridging Exchange (DCBX)

Answer

Enhanced Transmission Selection (ETS)

Answer

Jumbo frames

Question 5

A network administrator needs to configure iSCSI multipath I/O (MPIO) for a host connecting to a storage array. Which requirement must be met to ensure that MPIO functions correctly with load balancing?

Accepted Answer

The host must have multiple network interfaces on different subnets. MPIO requires multiple paths between the initiator and target. Each path must be on a separate network interface and subnet to provide redundancy and load balancing.

Answer

The iSCSI initiator must use CHAP authentication

Answer

Jumbo frames must be enabled on all switches

Answer

The storage array must support synchronous replication

Question 6

Which FC addressing component is used to uniquely identify a host bus adapter (HBA) port in a Fibre Channel fabric, and is often used for zoning?

Accepted Answer

World Wide Port Name (WWPN). The World Wide Port Name (WWPN) is a globally unique 64-bit identifier assigned to each Fibre Channel port, commonly used for hard zoning.

Answer

World Wide Node Name (WWNN)

Answer

Fibre Channel ID (FCID)

Answer

Domain ID

Question 7

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 8

Which Fibre Channel port type is used to connect two Cisco MDS switches together to form an inter-switch link (ISL)?

Accepted Answer

E-port. An E-port (Expansion port) is used for links between Fibre Channel switches to form the fabric.

Answer

N-port

Answer

NP-port

Answer

F-port

Question 9

A Cisco MDS switch is being configured to support multiple isolated Fibre Channel fabrics over a single physical infrastructure. Which feature should be used to achieve this isolation?

Accepted Answer

VSANs. Virtual SANs (VSANs) provide fabric isolation by creating separate logical fabrics within a single physical switch infrastructure, similar to VLANs in Ethernet.

Answer

VLANs

Answer

PortChannels

Answer

Zoning

Question 10

In an FCoE environment, which protocol is responsible for discovering and initializing FCoE-capable endpoints, including the exchange of MAC addresses and establishing virtual links?

Accepted Answer

FIP. The FCoE Initialization Protocol (FIP) is used to discover FCoE devices and establish virtual links before FCoE data frames are sent.

Answer

ARP

Answer

DCBX

Answer

FCoE

Question 11

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 12

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 13

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 14

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 15

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
