350-601 Storage Network Practice Test 15 — 15 Questions

Question 1

An engineer is designing a Fibre Channel fabric with two Cisco MDS switches for redundancy. The switches are connected via two ISLs. The engineer wants to aggregate the ISLs for higher throughput and load balancing. Which feature should be used?

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

Accepted Answer

PortChannel. Fibre Channel PortChannels allow aggregation of multiple physical ISLs into a single logical link, providing increased bandwidth and load balancing.

Answer

EISL trunking

Answer

VSAN load balancing

Answer

NPV mode

Question 2

A storage array supports both synchronous and asynchronous replication. The application requires zero data loss in case of a site failure. Which replication type should be chosen?

Accepted Answer

Synchronous replication. Synchronous replication writes data to the primary and secondary storage before acknowledging the write, ensuring zero data loss (RPO=0). Asynchronous replication may have some lag.

Answer

Asynchronous replication

Answer

Thin provisioning

Answer

Snapshot-based replication

Question 3

An engineer is configuring iSCSI CHAP authentication between an initiator and a target. The initiator has a CHAP username and secret configured. What must be configured on the target?

Accepted Answer

The same username and secret as the initiator.. For one-way CHAP, the target must have the same username and secret to authenticate the initiator. For mutual CHAP, additional configuration is needed, but the question implies one-way CHAP.

Answer

A different username and secret.

Answer

No CHAP configuration is needed on the target.

Answer

Only the secret, no username.

Question 4

Which Fibre Channel address component identifies a specific port on a node?

Accepted Answer

WWPN. The WWPN (World Wide Port Name) is a unique 64-bit identifier assigned to each Fibre Channel port. The WWNN identifies the node.

Answer

WWNN

Answer

FCID

Answer

WWN

Question 5

An organization's storage network uses RAID-10 for critical databases. The storage array has 12 disks. How many disks can fail simultaneously without data loss, assuming the worst-case scenario?

Accepted Answer

6. RAID-10 combines mirroring and striping. With 12 disks, there are 6 mirrored pairs. Data is lost only if both disks in the same mirror fail. Therefore, as long as no more than one disk per mirror fails, up to 6 disks can fail simultaneously without data loss. The phrase 'worst-case scenario' often confuses candidates into thinking only 1 failure is tolerable, but the question asks for the maximum number that can fail without data loss, which is 6.

Question 6

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 7

A storage administrator is configuring Fibre Channel zoning on a Cisco MDS switch to restrict access between initiators and targets. Which two statements about hard zoning vs. soft zoning are true? (Choose two.)

Accepted Answer

Hard zoning provides security against WWPN spoofing.. Hard zoning uses hardware ACLs to enforce access at the port level, providing security against WWPN spoofing. Soft zoning relies on the name server to filter responses, but a device can still attempt to communicate; it is less secure.

Answer

Hard zoning uses the Fibre Channel name server to restrict access.

Answer

Both hard and soft zoning require the active zone set to be configured.

Answer

Soft zoning enforces access at the hardware level.

Question 8

An engineer is implementing storage virtualization with thin provisioning on a Pure Storage array. Which three benefits does thin provisioning provide? (Choose three.)

Accepted Answer

Ability to over-allocate storage. Thin provisioning allows over-allocation, reduces upfront capacity costs, and improves storage utilization by allocating space on demand.

Answer

Simplified snapshot management

Answer

Guaranteed performance isolation

Question 9

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 10

An engineer is configuring a new Cisco MDS 9148 switch to connect to an existing Fibre Channel fabric. The switch will be used at the edge of the SAN and must not participate in fabric services. Which port mode should be used for the ports connecting to the core switches?

Accepted Answer

NP-port. NPV mode allows an edge switch to forward traffic to the core without participating in fabric services, reducing domain IDs and simplifying management.

Answer

F-port

Answer

E-port

Answer

N-port

Question 11

A storage administrator is configuring zoning on a Cisco MDS switch. They need to ensure that only the specified WWPNs can communicate, even if a device is moved to a different physical port. Which zoning method should be used?

Accepted Answer

Hard zoning by WWPN. Hard zoning based on WWPN is persistent across port changes, while soft zoning based on port ID is less secure and changes if the device moves.

Answer

Broadcast zoning

Answer

LUN zoning

Answer

Soft zoning by port ID

Question 12

A data center architect is designing a Fibre Channel fabric using Cisco MDS switches. To reduce the number of domain IDs and simplify management, the edge switches will operate in NPV mode. However, the core switches must be configured appropriately. Which port type must be used on the core switches to connect to NPV edge switches?

Accepted Answer

F-port. In NPV mode, the edge switch uses NP-ports to connect to the core. The core switch must have F-ports to accept these connections.

Answer

N-port

Answer

E-port

Answer

NP-port

Question 13

An engineer is configuring a Fibre Channel over Ethernet (FCoE) deployment. The network must ensure lossless transport for FCoE traffic. Which Data Center Bridging (DCB) feature must be enabled to provide no-drop service for FCoE frames?

Accepted Answer

Priority Flow Control (PFC). Priority Flow Control (PFC) is a DCB mechanism that provides per-priority pause to ensure lossless delivery for FCoE traffic.

Answer

Jumbo frames

Answer

Enhanced Transmission Selection (ETS)

Answer

Data Center Bridging Exchange (DCBX)

Question 14

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 15

A data center team is configuring a Cisco MDS switch to support multiple isolated SAN environments on the same physical infrastructure. They need to create separate fabrics that are completely isolated at Layer 2. Which technology should be used?

Accepted Answer

VSANs. VSANs provide isolation similar to VLANs in Ethernet, allowing multiple virtual Fibre Channel fabrics on the same physical switch.

Answer

NPV

Answer

Zoning

Answer

PortChannels
