350-601 Practice Test 20 — 15 Questions

Question 1

An organization uses synchronous replication between two storage arrays for disaster recovery. Which three characteristics apply to synchronous replication? (Choose three.)

Accepted Answer

Write acknowledgment is sent only after data is written to both arrays.. Synchronous replication writes data to both primary and secondary arrays before acknowledging the write. This ensures zero RPO and minimal data loss, but increases write latency due to the round trip. It is typically used over short distances.

Answer

It requires less bandwidth than asynchronous replication.

Answer

It is suitable for long-distance links with high latency.

Question 2

An engineer is designing an NPV deployment to scale the number of hosts connected to a Fibre Channel fabric. In NPV mode, which port type is used on the NPV switch to connect to the core switch?

Accepted Answer

NP_port. In NPV mode, the edge switch uses NP_ports to connect to the core switch's F_ports. NP_ports behave like N_ports and log in to the core fabric.

Answer

VN_port

Answer

E_port

Answer

F_port

Question 3

A storage administrator is configuring iSCSI security. Which two methods can be used to authenticate iSCSI initiators to a target? (Choose two.)

Accepted Answer

CHAP. CHAP is the standard authentication for iSCSI, and IP-based ACLs are a common access control method. Mutual CHAP is an option, but CHAP is the base.

Answer

WWN zoning

Answer

FCoE VLANs

Answer

VSAN membership

Question 4

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 5

An administrator is configuring a Cisco MDS switch for FCoE. Which two DCB features must be enabled to support FCoE traffic? (Choose two.)

Accepted Answer

Data Center Bridging Exchange (DCBX). FCoE requires lossless Ethernet. PFC provides no-drop priority for FCoE traffic, and DCBX is used to negotiate PFC and other parameters between peers.

Answer

Jumbo frames

Answer

Link Aggregation Control Protocol (LACP)

Answer

Enhanced Transmission Selection (ETS)

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 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?

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 8

A data center uses FCoE to consolidate storage and LAN traffic. Which IEEE standard ensures that FCoE frames are not dropped due to congestion by providing lossless Ethernet?

Accepted Answer

PFC (Priority Flow Control). Priority Flow Control (PFC, IEEE 802.1Qbb) creates lossless lanes by pausing traffic on specific priorities to prevent drops. ETS allocates bandwidth, and DCBX exchanges capabilities.

Answer

ETS (Enhanced Transmission Selection)

Answer

FIP (FCoE Initialization Protocol)

Answer

DCBX (Data Center Bridging Exchange)

Question 9

Which FCoE port type is analogous to an N-port in traditional Fibre Channel and connects to a VF-port on an FCoE switch?

Accepted Answer

VN-port. In FCoE, VN-port is the virtual equivalent of an N-port, and VF-port is the equivalent of an F-port. A VN-port connects to a VF-port.

Answer

VF-port

Answer

VE-port

Answer

NP-port

Question 10

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 11

A storage administrator has deployed a Fibre Channel fabric with two MDS switches. Each host has a single HBA. Which port type is used to connect the HBA to the switch?

Accepted Answer

N-port. An N-port is a host (node) port that connects to an F-port on the switch. The HBA operates in N-port mode by default.

Answer

F-port

Answer

E-port

Answer

NP-port

Question 12

A network administrator is configuring iSCSI multipath I/O (MPIO) for a storage array. Which two conditions are required for MPIO to operate correctly? (Choose two.)

Accepted Answer

The storage array must be configured with multiple target portals (IP addresses).. MPIO requires multiple network paths between the initiator and target. The target must present multiple IP addresses (one per path) and the initiator must have multiple network interfaces.

Answer

The target must present a single IP address for all paths.

Answer

The initiator and target must use CHAP authentication.

Answer

Jumbo frames must be enabled on all switches.

Question 13

An engineer is configuring a new Fibre Channel switch in a Cisco MDS environment. The switch will connect to end devices such as servers and storage arrays. Which two port types will be used on the switch to connect to these end devices?

Accepted Answer

F_port and FL_port. On a Fibre Channel switch, F_ports connect to N_ports on hosts and storage. N_ports are on end devices, not on the switch. E_ports are for ISLs between switches. NP_ports are used in NPV mode.

Answer

NP_port and VF_port

Answer

E_port and TE_port

Answer

N_port and NL_port

Question 14

A network engineer is configuring FCoE on a Cisco Nexus switch. Which two DCB features must be enabled to support lossless Ethernet for FCoE traffic? (Choose two.)

Accepted Answer

PFC (Priority Flow Control). PFC (Priority Flow Control) provides per-priority pause to prevent frame loss, and ETS (Enhanced Transmission Selection) allocates bandwidth among traffic classes.

Answer

IGMP snooping

Answer

STP (Spanning Tree Protocol)

Answer

LACP (Link Aggregation Control Protocol)

Question 15

An administrator wants to create separate FC fabrics on a single Cisco MDS switch for isolation of production and backup traffic. Which technology should they use?

Accepted Answer

VSAN. VSANs (Virtual SANs) provide fabric isolation on the same physical switch, similar to VLANs. Each VSAN has its own fabric services, zoning, and domain ID.

Answer

PortChannel

Answer

NPV
