350-601 Storage Network Practice Test 6 — 15 Questions

Question 1

An engineer is configuring iSCSI multipath I/O (MPIO) on a Windows server connected to a storage array. The goal is to provide load balancing and failover. What must be configured on the storage side to support MPIO?

Accepted Answer

Multiple iSCSI target IP addresses presenting the same LUN. MPIO requires that the storage array presents the same LUN to the server through multiple target portal groups or multiple iSCSI target IP addresses.

Answer

Jumbo frames

Answer

CHAP authentication

Answer

Thin provisioning

Question 2

A data center team is planning a Fibre Channel fabric with multiple Cisco MDS switches. They want to ensure that all switches share the same configuration and that zone changes are propagated automatically. Which feature should be enabled?

Accepted Answer

Cisco Fabric Services (CFS). Cisco Fabric Services (CFS) distributes configuration changes across all switches in the fabric, including zone changes.

Answer

NPV mode

Answer

Fibre Channel Security Protocol (FC-SP)

Answer

VSAN trunking (EISL)

Question 3

An engineer is configuring a Fibre Channel SAN with a Cisco MDS switch. To ensure high availability and load balancing, the engineer plans to use PortChannels. Which two statements about Fibre Channel PortChannels are true? (Choose two.)

Accepted Answer

PortChannels provide redundancy by automatically failing over to another link.. Fibre Channel PortChannels on Cisco MDS switches provide link redundancy by automatically redistributing traffic if a member link fails. All member ports must belong to the same VSAN for the PortChannel to operate correctly. While PortChannels can aggregate up to 16 physical links, the question asks for two true statements; options A and C are the most fundamental characteristics.

Answer

PortChannels require the use of the LACP protocol.

Answer

PortChannels are supported only between F-ports.

Answer

PortChannels can aggregate up to 16 physical links.

Question 4

A storage administrator is implementing synchronous replication between two storage arrays over a Fibre Channel link. Which three characteristics are true of synchronous replication? (Choose three.)

Accepted Answer

It requires a high-bandwidth, low-latency link between the arrays.. Synchronous replication writes data to both arrays before acknowledging the write, ensuring zero data loss but adding latency and requiring high bandwidth.

Answer

It is suitable for long-distance replication over hundreds of kilometers.

Answer

It uses less bandwidth than asynchronous replication.

Question 5

An engineer is configuring FCoE on a Cisco Nexus switch. Which two components are required for FCoE initialization? (Choose two.)

Accepted Answer

VN-port (Virtual N-port). FIP is used to discover and initialize FCoE devices, and VN-ports are the virtual FC ports on the switch that connect to VN-ports on the host.

Answer

Fibre Channel Security Protocol (FC-SP)

Answer

Enhanced Transmission Selection (ETS)

Answer

VF-port (Virtual F-port)

Question 6

A storage administrator connects a host to an MDS switch via Fibre Channel. The host has an HBA with WWPN 21:00:00:1b:32:12:34:56. Which port type does the MDS switch automatically configure on the interface connecting to the host?

Accepted Answer

F-port. When a host (N-port) connects to a switch, the switch operates as an F-port (fabric port) to provide fabric services. Cisco MDS switches auto-detect and configure the port as F-port unless specifically set otherwise.

Answer

Trunk port

Answer

NP-port

Answer

E-port

Question 7

An engineer configures zoning on a Cisco MDS switch to restrict access between storage arrays and servers. They use the command 'zone name ZONE1 vsan 10' and 'member pwwn 21:00:00:1b:32:12:34:56'. Which type of zoning is being configured?

Accepted Answer

Hard zoning by WWN. Hard zoning uses WWN (pwwn) to define zone members, and traffic is permitted only between members in the same zone. Soft zoning uses port IDs and relies on name server lookups.

Answer

VSAN zoning

Answer

Soft zoning by port

Answer

Lun zoning

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

A network engineer is designing an NPV environment with Cisco MDS switches. The edge switch is configured in NPV mode. Which port type does the edge switch present to the core switch when connecting upstream?

Accepted Answer

NP-port. In NPV mode, the edge switch presents an NP-port (N-port proxy) to the core switch's F-port. The NP-port behaves like an N-port but aggregates traffic from multiple downstream N-ports.

Answer

N-port

Answer

E-port

Answer

F-port

Question 10

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

Answer

Zoning

Question 11

A storage array is configured with RAID 10 across 8 disks. How many disks can fail without data loss, assuming optimal configuration?

Accepted Answer

4. RAID 10 mirrors data across two sets and stripes. In a configuration of 8 disks (4 mirrors), one disk per mirror can fail, so up to 4 disks can fail as long as no mirror loses both disks.

Answer

8

Answer

1

Answer

2

Question 12

During iSCSI configuration, the storage administrator requires authentication between initiator and target. Which method uses a bidirectional secret to verify both ends?

Accepted Answer

CHAP. CHAP (Challenge Handshake Authentication Protocol) can be one-way or mutual. Mutual CHAP requires both initiator and target to authenticate each other using secrets.

Answer

RADIUS

Answer

IPsec

Answer

Kerberos

Question 13

An engineer is configuring Fibre Channel PortChannels on a Cisco MDS switch. Which statement about Fibre Channel PortChannels is true?

Accepted Answer

They load-balance based on the source and destination WWPNs.. Fibre Channel PortChannels require all member ports to be of the same type (e.g., all E-ports). They load-balance across links and are compatible with VSAN trunking. They do not require the same speed on all ports, but it is recommended.

Answer

They require all member ports to be on the same VSAN.

Answer

They can include both E-ports and F-ports in the same PortChannel.

Answer

They are supported only in NPV mode.

Question 14

Which Fibre Channel address component uniquely identifies a port within a fabric and is assigned during fabric login (FLOGI)?

Accepted Answer

FCID. The FCID (Fibre Channel ID) is a 24-bit address assigned by the switch upon FLOGI. It consists of Domain, Area, and Port fields. WWPN is a permanent identifier, not assigned dynamically.

Answer

WWNN

Answer

Domain ID

Answer

WWPN

Question 15

A storage array uses thin provisioning. A volume is created with a virtual size of 1 TB but only 100 GB of physical storage is allocated initially. What happens when the host writes data beyond the currently allocated physical space?

Accepted Answer

The array automatically extends the volume by allocating more physical blocks from the pool.. Thin provisioning allocates physical storage on demand. Additional storage is allocated from a shared pool as needed. The array may overcommit, but writes succeed as long as pool has free space.

Answer

The write fails immediately.

Answer

The host must reconfigure the volume size.

Answer

The volume is expanded to 1 TB physical.
