350-601 Storage Network Practice Test 14 — 15 Questions

Question 1

An engineer needs to connect a Cisco MDS switch to a core Fibre Channel fabric using NPV mode. What port type will the edge switch's uplink ports assume in this scenario?

Accepted Answer

NP-port. In NPV mode, the edge switch presents NP-ports to the core fabric, which appear as N-ports to the core switch.

Answer

N-port

Answer

E-port

Answer

F-port

Question 2

A storage administrator configures zoning on a Cisco MDS switch. The requirement is to prevent any changes to the zone set from taking effect unless explicitly activated. Which configuration is correct?

Accepted Answer

Create zones, add them to the zone set, then activate the zone set.. The active zone set is the only zone set that is enforced; changes must be activated to apply.

Answer

Create zones and directly add them to the database; activation is automatic.

Answer

Create zones and add them to the active zone set; deactivate the zone set to apply changes.

Answer

Create zones and add them to the full zone set; the switch automatically activates changes.

Question 3

Which of the following is a requirement for iSCSI storage connectivity to support jumbo frames?

Accepted Answer

Configure MTU 9000 on all involved interfaces. Jumbo frames require an MTU of 9000 bytes on all interfaces in the path.

Answer

Enable PFC on the switch

Answer

Enable MPIO

Answer

Use CHAP authentication

Question 4

What is the purpose of FIP (FCoE Initialization Protocol) in an FCoE network?

Accepted Answer

To discover FCoE-capable devices and establish virtual links. FIP is used to discover and initialize FCoE devices and establish virtual links before FCoE data frames can be sent.

Answer

To provide flow control for FCoE traffic

Answer

To negotiate DCB parameters

Answer

To encapsulate FC frames into Ethernet frames

Question 5

A Cisco MDS switch has multiple Fibre Channel interfaces that need to be aggregated into a single logical interface to increase bandwidth and provide redundancy. Which technology should be used?

Accepted Answer

PortChannel. PortChannels in Fibre Channel aggregate multiple physical links into one logical link.

Answer

VSAN load balancing

Answer

NPV mode

Answer

EISL trunking

Question 6

Which type of zoning uses the World Wide Port Name (WWPN) to define zone members, providing better security because WWPNs are globally unique?

Accepted Answer

Hard zoning by WWPN. Hard zoning by WWPN uses WWPNs to define members, and is considered more secure than soft zoning by port.

Answer

Soft zoning by port

Answer

VSAN-based zoning

Answer

LUN masking

Question 7

An engineer is deploying iSCSI storage in a data center. Which two features should be configured to improve performance and redundancy? (Choose two.)

Accepted Answer

Jumbo frames (MTU 9000). MPIO provides path redundancy and load balancing; jumbo frames reduce CPU overhead and improve throughput.

Answer

VSAN

Answer

CHAP authentication

Answer

FCoE

Question 8

A storage architect is designing a disaster recovery solution with a storage array supporting replication. Which three factors should be considered when choosing between synchronous and asynchronous replication? (Choose three.)

Accepted Answer

Network bandwidth availability. Synchronous replication provides zero RPO but impacts performance over distance; asynchronous has higher RPO but lower latency impact and can be used over longer distances.

Answer

Fibre Channel zoning configuration

Answer

Storage array RAID level

Question 9

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 10

An engineer is configuring a new Cisco MDS switch to connect to an existing Fibre Channel fabric. The switch will be deployed in NPV mode to scale the number of edge ports. Which port type should be used on the upstream switch to connect to this NPV switch?

Accepted Answer

F-port. In NPV mode, the edge switch registers with the core switch using NPIV. The core switch sees the NPV switch as a host and the port connecting to it must be an F-port.

Answer

E-port

Answer

N-port

Answer

NP-port

Question 11

A storage administrator wants to implement Fibre Channel zoning to ensure that only specific initiators can access specific targets. The administrator prefers a method that does not require reconfiguration when a host's HBA is replaced with a new one with a different WWPN. Which zoning type meets this requirement?

Accepted Answer

Soft zoning by port. Soft zoning by port uses the physical port number, not the WWPN. If the HBA is replaced but the same port is used, the zoning remains valid. Hard zoning by WWN would require updating the zone if the WWPN changes.

Answer

Hard zoning by port

Answer

Soft zoning by WWN

Answer

Hard zoning by WWN

Question 12

An engineer is deploying FCoE in a data center and must ensure lossless transport for Fibre Channel traffic over Ethernet. The engineer configures Priority Flow Control (PFC) on the DCB-enabled switches. However, FCoE initialization fails. Which additional DCB feature is required to enable FCoE devices to discover and negotiate PFC settings with the switch?

Accepted Answer

DCBX (Data Center Bridging Exchange). DCBX (Data Center Bridging Exchange) is used to exchange DCB parameters between peers, including PFC and ETS. FIP uses DCBX to discover FCoE-capable switches and negotiate PFC.

Answer

CN (Congestion Notification)

Answer

ETS (Enhanced Transmission Selection)

Answer

QoS (Quality of Service)

Question 13

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 14

An engineer is configuring iSCSI multipath I/O (MPIO) for a storage array. The initiator has two NICs connected to two different switches, and the target has two iSCSI ports on different subnets. Which condition must be met for MPIO to function correctly?

Accepted Answer

Each path must be on a separate subnet.. MPIO requires that the initiator and target have multiple paths that are not on the same subnet to avoid routing issues. Typically, each path should be on a separate subnet.

Answer

CHAP authentication must be disabled.

Answer

Both paths must be on the same subnet.

Answer

Jumbo frames must be enabled on all interfaces.

Question 15

A storage administrator is configuring Fibre Channel zoning on a Cisco MDS switch. The administrator creates a zone, adds members, and activates the zone set. However, the hosts still cannot access the storage targets. What is the most likely cause?

Accepted Answer

The zone set was not activated.. Zoning changes only take effect when the zone set is activated. If the zone set is not activated, the zones are not enforced.

Answer

The WWPNs are incorrectly typed.

Answer

The VSAN was not created.

Answer

The ports are in trunk mode.
