Domain overview
The Storage Network domain covers Fibre Channel, FCoE, and SAN connectivity on Cisco Nexus and MDS platforms. Questions test VSANs, zoning, NPV/NPIV, FLOGI/FDISC, and FCoE VLAN and FEX design. Expect scenario items on access control, endpoint login failures, and fabric best practices rather than pure theory.
Exam objectives
VSAN creation, trunking, and zone set activation with zone members
NPV, NPIV, and FLOGI/FDISC login behavior between edge and core switches
FCoE VLAN configuration, VFC interfaces, and FEX-based FCoE design
Zoning types and LUN masking to restrict initiator-to-target access
Assuming FCoE can share the native or default VLAN; dedicated FCoE VLANs are required and must not carry other traffic.
Confusing NPV with NPIV: NPV is a switch feature that aggregates logins, NPIV lets an N-port present multiple WWNs.
Forgetting that zoning is enforced by the fabric, while LUN masking is enforced at the target or host layer.

177A 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?
178A 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.)
179A 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?
180A 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?
181A 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?
182A 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.)
183A 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?
184A 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.)
185A 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?
186A storage administrator is configuring a new Cisco MDS 9000 switch. The fabric will use FLOGI and FCNS to manage device logins and name services. The administrator needs to ensure that the switch can properly handle the login process for a new host. Which database on the MDS switch stores the mapping between the Fibre Channel ID (FCID) and the port world wide name (pWWN) after a successful FLOGI?
187An administrator is configuring zoning on a Cisco MDS switch. The requirement is to allow a specific host HBA port to communicate with a specific storage array port, but also to allow that same host to communicate with a second storage array port. The administrator wants to minimize the number of zones and use a single zone name. Which zoning method should be used?
188A network engineer is troubleshooting a Cisco MDS 9000 switch where a host is unable to access a storage array. The engineer runs the command 'show flogi database' and sees the host's WWPN, but the storage array's WWPN is missing. The engineer verifies that the storage array is powered on and connected to a different switch in the same fabric. What is the most likely cause?
189A storage engineer is implementing VSANs on a Cisco MDS 9000 switch to isolate traffic between different departments. The engineer needs to ensure that devices in different VSANs cannot communicate with each other, and that each VSAN has its own fabric services. Which two statements about VSANs are true? (Choose two.)
190A storage administrator is configuring a Cisco MDS 9000 switch to present a LUN to a host through a specific target port. The administrator wants to ensure that the host can access the LUN only through that target port and no other port on the same storage array. Which zoning configuration should be used?
191A network engineer is implementing VSANs on a Cisco MDS 9000 switch to segment traffic between different departments. The engineer needs to ensure that VSANs provide isolation and that devices in different VSANs cannot communicate. Which two statements are true regarding VSANs on Cisco MDS switches? (Choose two.)
