350-601 Storage Network Practice Test 22 — 15 Questions

Question 1

A network engineer is troubleshooting a Cisco MDS 9000 switch where a host cannot communicate with its storage array. The host is logged into the fabric, and the zone set is active. The engineer suspects a domain ID conflict. Which command should be used to verify the domain ID assignments and any conflicts in the fabric?

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

Accepted Answer

show fcdomain domain-list vsan 10. Domain ID conflicts can prevent proper communication in a Fibre Channel fabric. The 'show fcdomain domain-list' command lists all domain IDs in a VSAN, allowing an administrator to spot duplicates or conflicts. This is the correct tool for verifying domain ID assignments and ensuring fabric stability.

Answer

show fspf database vsan 10

Answer

show zone active vsan 10

Answer

show flogi database vsan 10

Question 2

A network engineer is configuring a Cisco MDS 9000 switch. The engineer needs to verify the WWPN of the HBA connected to interface fc1/1. Which command should be used?

Accepted Answer

show flogi database. The show flogi database command is the correct choice because it lists all devices that have performed fabric login, including their WWPNs and the interfaces they are connected to. This allows the engineer to directly find the WWPN associated with fc1/1. The other commands provide interface statistics, name server entries, or zoning information, but none directly map an interface to a logged-in device's WWPN.

Answer

show interface fc1/1

Answer

show zoneset active vsan 1

Answer

show fcns database

Question 3

A network engineer is configuring a Cisco MDS 9000 Series switch. They need to verify the current zoning configuration, including the active zone set and its members. Which command should they use?

Accepted Answer

show zoneset active. To verify the active zone set and its members on a Cisco MDS 9000 Series switch, the correct command is 'show zoneset active'. This command displays the active zone set name, the zones it contains, and the members of each zone. Other commands like 'show zone status' provide zoning parameters but not the active zone set details, while 'show flogi database' and 'show fcns database' show logged-in devices and name server entries, respectively.

Answer

show flogi database

Answer

show zone status

Answer

show fcns database

Question 4

A storage administrator is configuring an MDS 9700 switch port as an F_port in a VSAN where the core fabric edge ports are also F_ports. The requirement is to reduce the number of domain IDs consumed in the fabric because the fabric has already allocated domain IDs to all core switches. Which feature should be enabled on the MDS 9700 to allow the edge ports to connect without consuming an additional domain ID?

Accepted Answer

N_Port Virtualization (NPV) mode on the edge switch.. NPV mode allows an edge switch to connect to a core switch without consuming a domain ID, because the edge switch does not become a principal switch or request a domain ID. Instead, it forwards fabric login from attached nodes to the core. This directly addresses the scenario where domain IDs are exhausted, making NPV the correct feature to enable.

Answer

N_Port ID Virtualization (NPIV) on the core switch.

Answer

Inter-VSAN Routing (IVR) on the MDS 9700.

Answer

PortChannel with F_port trunking on the MDS 9700.

Question 5

A Cisco MDS 9000 switch is connected to a storage array via an ISL. The administrator notices that the link is experiencing buffer credit starvation under peak load. The switch port is configured as an E_port with a default buffer-to-buffer credit value. Which action should be taken to alleviate the credit starvation while preserving the existing physical topology?

Accepted Answer

Enable extended buffer-to-buffer credits on the ISL and configure the required credits per port.. Extended buffer-to-buffer credits increase the number of outstanding frames that can be sent on a link, which is especially useful on long-distance or high-latency ISLs where standard credits are insufficient. Configuring extended credits on the E_port directly alleviates credit starvation without altering the physical topology, making it the correct choice.

Answer

Disable QoS and remove any bandwidth throttling on the ISL.

Answer

Enable NPIV on the storage array port to increase the number of virtual N_ports.

Answer

Convert the ISL to an F_port and connect the storage array directly to the core switch.

Question 6

A network engineer is configuring a Cisco Nexus 9000 switch for FCoE. The switch needs to carry Fibre Channel traffic over Ethernet. Which feature must be enabled on the switch?

Accepted Answer

FCoE. To carry Fibre Channel traffic over Ethernet, the FCoE feature must be enabled on the switch. This allows the switch to encapsulate Fibre Channel frames into Ethernet frames and forward them over the Ethernet network. Other features like DCBX or NPV serve different purposes and do not provide the core FCoE functionality.

Answer

NPV

Answer

FCoE NPV

Answer

DCBX

Question 7

A storage engineer is troubleshooting a Fibre Channel link between a Cisco MDS switch and a storage array. The link is not coming up, and the engineer suspects a speed mismatch. The switch port is configured for auto-negotiation, but the storage array is hard-set to 8 Gbps. What is the most likely cause of the link failure?

Accepted Answer

The switch port must be configured for 8 Gbps explicitly because auto-negotiation is not supported with hard-set speeds on the array.. When one end of a Fibre Channel link is hard-set to a specific speed and the other is set to auto-negotiate, the link may fail because auto-negotiation requires both ends to participate. The correct resolution is to configure the switch port to the same fixed speed as the storage array. Therefore, explicitly setting the switch port to 8 Gbps is the most likely fix.

Answer

The switch port must be configured for 4 Gbps because that is the default speed for auto-negotiation.

Answer

The link failure is due to a faulty cable and has nothing to do with speed settings.

Answer

The storage array must be set to auto-negotiate to match the switch port configuration.

Question 8

A data center engineer is designing a Fibre Channel SAN with Cisco MDS switches. The engineer needs to ensure that the fabric supports Inter-VSAN Routing (IVR) for communication between devices in different VSANs. Which two statements about IVR are true? (Choose two.)

Accepted Answer

IVR allows devices in different VSANs to communicate without merging the VSANs.. IVR enables communication between devices in different VSANs without merging them, preserving isolation. It uses a transit VSAN to route traffic between edge VSANs. These two statements are true: IVR allows cross-VSAN communication without merging, and it employs a transit VSAN for routing. The other options are false because IVR does not require a special IVR-enabled VSAN, does not require all switches to be IVR-enabled, and does not merge VSANs.

Answer

IVR requires a special IVR-enabled VSAN to route traffic between VSANs.

Answer

IVR requires all switches in the fabric to be IVR-enabled.

Answer

IVR automatically merges VSANs to simplify management.

Question 9

A data center architect is designing a Fibre Channel SAN with two Cisco MDS switches. The architect wants to ensure that if one switch fails, the other switch can continue to provide access to storage without manual intervention. Which technology should be implemented?

Accepted Answer

Multipathing with MPIO or DM-Multipath. To ensure continuous access to storage if a switch fails, the host must use multipathing software that can detect path failures and switch to an alternate path. This is typically implemented with MPIO or DM-Multipath. While other technologies like VSAN trunking, PortChannel, and FSPF contribute to a resilient fabric, they do not provide the end-to-end failover needed at the host level.

Answer

PortChannel

Answer

VSAN trunking

Answer

FSPF

Question 10

A data center administrator is configuring a new Cisco MDS 9000 switch. They need to ensure that the switch can participate in a fabric with other switches and that it can be managed remotely. Which management interface should be configured with an IP address for remote management?

Accepted Answer

The management Ethernet interface (mgmt0). The management Ethernet interface (mgmt0) is designed for out-of-band management and supports IP addressing. It allows administrators to connect remotely using SSH, Telnet, or SNMP. While VSAN interfaces can also provide in-band management, the question asks for the interface that should be configured for remote management, which is typically the management Ethernet interface.

Answer

The console interface

Answer

The Fibre Channel interfaces

Answer

The VSAN interface

Question 11

A storage engineer is configuring a Cisco MDS switch to support NPV mode. The switch will connect to a core SAN switch. After enabling NPV mode, the engineer notices that the NPV switch is not able to log into the core switch. Which action should the engineer take to resolve this issue?

Accepted Answer

Configure the uplink port as an NP port.. In NPV mode, the switch acts as a proxy for its connected devices, forwarding their logins to the core switch. The uplink port to the core must be configured as an NP port. This allows the NPV switch to present itself as an N port to the core switch's F port. Without NP port configuration, the NPV switch cannot establish the necessary connection for devices to log in.

Answer

Configure the uplink port as a TE port.

Answer

Configure the uplink port as an E port.

Answer

Configure the uplink port as an F port.

Question 12

A data center engineer is configuring VSANs on a Cisco MDS 9000 Series switch. They need to ensure that the VSANs are properly isolated and that devices can communicate only within their assigned VSAN. Which two statements about VSAN configuration are true? (Choose two.)

Accepted Answer

Inter-VSAN routing (IVR) is required for devices in different VSANs to communicate.. VSANs provide logical isolation, with each VSAN having its own fabric services such as zoning, name server, and domain ID. Devices in different VSANs cannot communicate unless Inter-VSAN Routing (IVR) is configured. A physical port belongs to only one VSAN unless trunking is used, and VSANs do not require separate physical switches. They are supported on both MDS and Nexus platforms.

Answer

VSANs require separate physical switches for each VSAN to ensure isolation.

Answer

A physical port can be a member of multiple VSANs simultaneously without trunking.

Answer

VSANs can be configured only on Cisco Nexus switches, not on Cisco MDS switches.

Question 13

A storage engineer is implementing SAN boot for a Cisco UCS B-Series blade server. The server must boot from a Fibre Channel LUN on a NetApp array. The engineer has configured the vHBA, zoning, and boot policy. However, the server fails to boot from SAN. Which action should be taken to ensure the correct LUN is presented to the server during boot?

Accepted Answer

Verify that the LUN is masked to the correct initiator WWN on the storage array.. SAN boot requires that the boot LUN be masked to the server's initiator WWN on the storage array. Even with correct zoning and boot policy, if the LUN is not presented to the initiator, the server cannot boot. Verifying LUN masking on the NetApp array ensures the server sees the LUN.

Answer

Enable NPIV on the upstream Cisco MDS switch.

Answer

Configure the boot policy to use the primary vHBA and set the LUN ID to the correct value.

Answer

Change the VSAN membership of the vHBA to match the storage array's VSAN.

Question 14

A storage engineer is designing a Fibre Channel fabric that must support both block-level and file-level storage traffic. They plan to use Cisco MDS 9000 switches with VSANs to isolate traffic. Which two statements are true regarding VSANs? (Choose two.)

Accepted Answer

VSANs can be used to isolate FCoE traffic from native Fibre Channel traffic on the same physical infrastructure.. VSANs provide independent fabric services per VSAN and can isolate different traffic types, such as FCoE and native Fibre Channel, on the same physical infrastructure. They do not require separate physical switches per VSAN; a single switch can participate in multiple VSANs. IVR is optional for inter-VSAN communication, and VSANs do not require a separate license.

Answer

A single physical switch can participate in multiple VSANs, but each VSAN requires a separate physical switch.

Answer

VSANs require a separate license on Cisco MDS switches.

Answer

Inter-VSAN routing (IVR) is required to allow devices in different VSANs to communicate.

Question 15

A data center engineer is implementing Fibre Channel over IP (FCIP) between two Cisco MDS 9000 switches across a WAN link. The engineer wants to ensure that the FCIP tunnel remains operational even if the primary WAN path fails, and that traffic is load-balanced across multiple TCP connections. Which feature should be configured on the FCIP tunnel?

Accepted Answer

FCIP multi-path. FCIP multi-path enables the use of multiple TCP connections for a single FCIP tunnel, providing both redundancy and load balancing. If one WAN link fails, the tunnel remains up using other connections. This is essential for high availability across WAN links. The other options (compression, write acceleration, tape acceleration) are performance optimizations but do not provide path redundancy or load balancing.

Answer

FCIP write acceleration

Answer

FCIP compression

Answer

FCIP tape acceleration
