350-601 Practice Test 21 — 15 Questions

Question 1

A storage administrator needs to isolate Fibre Channel traffic between two departments in a data center using a single MDS switch. The administrator decides to create separate VSANs. Which statement about VSANs is true?

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

Accepted Answer

VSANs provide isolation similar to VLANs in Ethernet networks.. VSANs provide isolation similar to VLANs in Ethernet. Each VSAN has its own fabric services and does not share traffic with other VSANs.

Answer

VSANs share the same fabric services across all VSANs.

Answer

VSANs require separate physical interfaces for each VSAN.

Answer

VSANs cannot be used with FCoE.

Question 2

An engineer is configuring a Cisco MDS switch to connect to a core switch in NPV mode. The edge switch will be connected to the core via an ISL. What port mode should be configured on the edge switch's interface connecting to the core?

Accepted Answer

NP-port. In NPV mode, the edge switch uses NP-ports to connect to the core switch's F-ports. This allows the edge switch to appear as a host to the core fabric.

Answer

F-port

Answer

E-port

Answer

auto

Question 3

A network engineer is configuring a new Fibre Channel switch to connect to an existing storage fabric. The switch will be used to aggregate multiple edge switches and must appear as a single Fibre Channel device to the core. Which port type should be used on the edge switch facing the core switch to achieve this?

Accepted Answer

NP-port. NP-port (N-Port Virtualization) is used on an edge switch in NPV mode to connect to the core fabric; it behaves like an N-port but allows multiple N-port IDs behind it.

Answer

F-port

Answer

N-port

Answer

E-port

Question 4

Which TWO statements correctly describe active zone sets in a Cisco MDS Fibre Channel fabric?

Accepted Answer

The active zone set is propagated to all switches in the fabric. An active zone set is the set of zones that are enforced in the fabric. Only one zone set can be active at a time, and it is propagated to all switches in the fabric.

Answer

Zones within the active zone set can be selectively deactivated

Answer

The active zone set is stored in the running configuration only

Answer

Multiple zone sets can be active simultaneously

Question 5

During FCoE initialization, which protocol is used by a CNA to discover FCoE-capable switches and establish a virtual link?

Accepted Answer

FIP. FIP (FCoE Initialization Protocol) is used by CNAs to discover FCoE switches (FCFs) and perform login to create VN-ports.

Answer

LLDP

Answer

DCBX

Answer

ARP

Question 6

A storage administrator is setting up iSCSI connectivity between a server and a storage array. To enhance security, the administrator wants to authenticate the initiator and target during the login process. Which authentication method should be configured?

Accepted Answer

CHAP. CHAP is a standard authentication protocol for iSCSI that provides mutual authentication between initiator and target.

Answer

IPsec

Answer

RADIUS

Answer

Kerberos

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

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 9

A data center team is implementing FCoE and needs to ensure that FCoE traffic is not dropped during congestion. The network switches support Data Center Bridging (DCB). Which two DCB features are required for FCoE?

Accepted Answer

Priority Flow Control (PFC) and Data Center Bridging Exchange (DCBX). PFC provides lossless transport, and DCBX is used for capability exchange between peers to configure PFC and other DCB features.

Answer

Enhanced Transmission Selection (ETS) and Data Center Bridging Exchange (DCBX)

Answer

Enhanced Transmission Selection (ETS) and jumbo frames

Answer

Priority Flow Control (PFC) and jumbo frames

Question 10

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 11

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

Question 12

A storage administrator wants to provide a volume that appears larger than its actual physical capacity, allocating storage blocks only as data is written. Which storage provisioning method is being described?

Accepted Answer

Thin provisioning. Thin provisioning allows over-allocation of storage capacity, presenting a large logical volume to hosts while using physical storage only as needed.

Answer

Snapshot

Answer

Thick provisioning

Answer

RAID-5

Question 13

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 14

A Cisco MDS switch is configured with NPV mode. A host NPIV-capable HBA is connected to this switch. The HBA needs to log in with multiple N-port IDs to support multiple virtual machines. What must be configured on the MDS switch to allow this?

Accepted Answer

NPIV. NPIV (N_Port ID Virtualization) allows multiple FCIDs on a single N-port. On an NPV switch, NPIV must be enabled to allow the HBA to register multiple IDs.

Answer

PortChannel

Answer

VSAN trunking

Answer

Zoning

Question 15

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
