350-601 Practice Test 18 — 15 Questions

Question 1

A storage administrator is configuring a new Fibre Channel fabric using Cisco MDS switches. The edge switches must connect to the core without participating in the full routing domain to conserve domain IDs. Which Fibre Channel feature should be configured on the edge switches?

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

Accepted Answer

NPV mode. N-Port Virtualization (NPV) mode allows an edge switch to connect to a core switch without consuming a Fibre Channel domain ID, scaling the fabric while reducing administrative overhead.

Answer

PortChannels

Answer

VSANs

Answer

EISL trunking

Question 2

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 3

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 4

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 5

A NetApp storage array is configured for synchronous replication between two data centers. The round-trip latency is 2 ms. Which RAID type provides the best balance of capacity efficiency and protection for the primary storage volumes that are replicated?

Accepted Answer

RAID-10. RAID-10 offers high performance and availability with mirroring and striping, but capacity efficiency is lower (50% usable). RAID-6 provides better capacity efficiency (2 parity disks) but with higher write overhead. Given synchronous replication, RAID-10 is often preferred for performance.

Answer

RAID-5

Answer

RAID-6

Answer

RAID-0

Question 6

An engineer configures an ISL between two MDS switches using E_ports. To utilize all available bandwidth, the engineer wants to bundle four physical links into a single logical link. Which technology should be used?

Accepted Answer

Fibre Channel PortChannel. Fibre Channel PortChannels aggregate multiple physical links into one logical link, providing increased bandwidth and redundancy. This is similar to Ethernet port channels.

Answer

NPV mode

Answer

FCoE trunking

Answer

EISL trunking

Question 7

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 8

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 9

An administrator needs to configure zoning on a Cisco MDS switch. After creating zones and adding members, what must be done to activate the zoning configuration?

Accepted Answer

Assign zones to a zone set and then activate the zone set.. Zone sets must be activated to enforce zoning. The active zone set is the currently enforced zoning configuration. Multiple zone sets can be configured, but only one can be active.

Answer

Reboot the switch for changes to take effect.

Answer

Activate the zone set using the 'zone activate' command.

Answer

Save the configuration to startup-config.

Question 10

Which FC addressing component is used to uniquely identify a host bus adapter (HBA) port in a Fibre Channel fabric, and is often used for zoning?

Accepted Answer

World Wide Port Name (WWPN). The World Wide Port Name (WWPN) is a globally unique 64-bit identifier assigned to each Fibre Channel port, commonly used for hard zoning.

Answer

World Wide Node Name (WWNN)

Answer

Fibre Channel ID (FCID)

Answer

Domain ID

Question 11

An engineer is configuring a Cisco MDS switch to connect two SAN islands using a Fibre Channel ISL. The interfaces on both switches are set to auto mode. However, the link does not come up. What is the most likely cause?

Accepted Answer

The ports are in auto mode and neither side is configured as E-port.. On Cisco MDS switches, ports in auto mode negotiate to become F-ports by default. For an ISL, at least one side must be configured as E-port to force the link to become an E-port.

Answer

Both switches have the same domain ID.

Answer

The ISL link requires a minimum speed of 8 Gbps.

Answer

The ports are configured in F-port mode.

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 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 15

A Cisco MDS switch is connected to another MDS via a Fibre Channel link. The two switches need to carry traffic for multiple VSANs over a single physical link. Which feature should be configured?

Accepted Answer

EISL trunking. EISL (Enhanced ISL) allows multiple VSANs to be trunked over a single ISL.

Answer

NPV mode

Answer

PortChannel

Answer

VSAN-based zoning
