350-601 Storage Network Practice Test 12 — 15 Questions

Question 1

An engineer is configuring FCoE on a Cisco MDS switch and needs to ensure that the switch can communicate with FCoE-enabled servers. Which FCoE port type should be used on the switch to connect to a server's CNA?

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

Accepted Answer

VF_port. In FCoE, a VF_port (Virtual F_port) on the switch connects to a VN_port (Virtual N_port) on the server's CNA. This is analogous to an F_port connecting to an N_port in native FC.

Answer

VE_port

Answer

NP_port

Answer

VN_port

Question 2

An administrator needs to configure zoning on a Cisco MDS switch. After creating zones and adding members, what must be done to activate the zoning configuration?

Accepted Answer

Assign zones to a zone set and then activate the zone set.. Zone sets must be activated to enforce zoning. The active zone set is the currently enforced zoning configuration. Multiple zone sets can be configured, but only one can be active.

Answer

Reboot the switch for changes to take effect.

Answer

Activate the zone set using the 'zone activate' command.

Answer

Save the configuration to startup-config.

Question 3

Which two advantages does thin provisioning provide in a storage array? (Choose two.)

Accepted Answer

Allows over-provisioning of storage capacity.. Thin provisioning allows over-allocation of storage capacity, presenting more space to applications than physically available, improving utilization. It also reduces power and cooling costs by using fewer physical disks initially.

Answer

Increases write performance by using faster disks.

Answer

Reduces the need for snapshots.

Answer

Eliminates the need for RAID protection.

Question 4

Which three components are required for a fully functional FCoE deployment in a data center? (Choose three.)

Accepted Answer

DCB-enabled Ethernet switches. FCoE requires Converged Network Adapters (CNAs) on servers, DCB-enabled switches, and FIP for initialization. The other options are not mandatory.

Answer

iSCSI initiator software

Answer

Fibre Channel switches with E_ports

Question 5

An administrator is configuring CHAP authentication for iSCSI. Which two statements about CHAP are correct? (Choose two.)

Accepted Answer

CHAP authentication is optional and can be disabled.. CHAP uses a three-way handshake (challenge, response, verification) and can be configured as one-way (target authenticates initiator) or mutual (both authenticate).

Answer

CHAP provides encryption of iSCSI data.

Answer

CHAP authentication is only used for discovery sessions.

Answer

CHAP uses a digital certificate for authentication.

Question 6

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 7

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 8

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 9

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 10

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 11

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 12

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 13

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 14

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 15

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
