Question 2

A storage administrator is troubleshooting a connectivity issue between a server and a storage array over Fibre Channel. The server is connected to an NPV edge switch, which uplinks to a core switch. The server's WWPN is registered in the zone, but the server cannot see the target. The administrator notices that the core switch does not see the server's WWPN in its FC name server database. What is the most likely cause?

Accepted Answer

The NPV edge switch does not register host WWPNs in the core fabric's name server; only the NP-port WWPN is registered. In NPV mode, the edge switch does not propagate WWPNs to the core's name server; instead, the NP-port's WWPN is seen. The core sees the edge switch's NP-port WWPN, not the host's WWPN.

Answer

The host is using an incorrect FCID

Answer

The VSAN mismatch between edge and core switches

Answer

The zone set is not activated on the edge switch

Question 3

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 4

A storage administrator is configuring a new storage array that supports thin provisioning. The array reports 10 TB of physical storage and 50 TB of thin-provisioned logical capacity. Which risk is most important to monitor to avoid out-of-space conditions?

Accepted Answer

The rate of physical capacity consumption and remaining free space. Thin provisioning overcommits physical storage; monitoring actual physical usage and growth rate is critical to prevent running out of space.

Answer

High latency on the Fibre Channel links

Answer

The number of snapshots taken

Answer

The replication status

Question 5

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 6

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 7

An engineer is configuring a Fibre Channel PortChannel between two Cisco MDS switches. What is the maximum number of physical links that can be aggregated into a single PortChannel in Fibre Channel?

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

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. PortChannels can aggregate up to 16 physical links, not 4. LACP is not used in Fibre Channel; it is an Ethernet protocol. PortChannels are supported on both E-ports (inter-switch links) and F-ports (N-port connections).

Answer

PortChannels require the use of the LACP protocol.

Answer

PortChannels are supported only between F-ports.

Answer

PortChannels can aggregate up to 4 physical links.

Question 8

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 9

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 10

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 11

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 12

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 13

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 14

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 15

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.
