Question

Which statement about FCoE NPV in Cisco NX-OS and the Cisco Nexus 5000 Series Switches is true?

Answers

A. FCoE NPV and NPV cannot be implemented together because these two features use different mechanisms to communicate to the core switch.

B. FCoE NPV does not have the management and troubleshooting issues that are inherent to managing hosts remotely at the FC.

C. The FCoE NPV does not provide any equivalent FCoE Initialization Protocol snooping capabilities.

D. Connectivity from an FCoE NPV bridge to the FCF is supported over point-to-point links and when FCF is up to three hops away.

A. B. C. D.

FCoE NPV (Fibre Channel over Ethernet N-Port Virtualization) is a feature in Cisco NX-OS and the Cisco Nexus 5000 Series Switches that allows multiple FCoE (Fibre Channel over Ethernet) endpoints to share a single physical FCoE uplink to an FCoE forwarder (FCF) without requiring a full Fibre Channel switch. FCoE NPV is designed to simplify the management of FCoE networks and reduce the cost and complexity of deploying Fibre Channel fabrics.

The correct answer to the question is D. Here's why:

A. This statement is not true. FCoE NPV and NPV (N-Port Virtualization) can be implemented together, and in fact, FCoE NPV is a type of NPV. NPV is a feature that allows multiple Fibre Channel endpoints to share a single physical Fibre Channel uplink to a Fibre Channel core switch without requiring a full Fibre Channel switch. FCoE NPV extends the concept of NPV to FCoE.

B. This statement is not true. FCoE NPV has the same management and troubleshooting issues as NPV when managing hosts remotely at the Fibre Channel level. However, FCoE NPV can simplify management because it reduces the number of Fibre Channel switches in the network and allows FCoE traffic to be managed using Ethernet tools.

C. This statement is not true. FCoE NPV provides equivalent FCoE Initialization Protocol (FIP) snooping capabilities to NPV. FIP snooping is a feature that allows the Fibre Channel fabric to detect and control FCoE traffic.

D. This statement is true. FCoE NPV connectivity from an FCoE NPV bridge to the FCF is supported over point-to-point links, and FCF can be up to three hops away. This means that an FCoE NPV bridge can connect to an FCF that is up to three switches away over Fibre Channel or Ethernet links. FCoE NPV can be used to create a simplified FCoE network that uses fewer switches and cables than a traditional Fibre Channel network.

In conclusion, FCoE NPV is a feature in Cisco NX-OS and the Cisco Nexus 5000 Series Switches that simplifies the deployment and management of FCoE networks. FCoE NPV can be used with NPV, and it provides equivalent FIP snooping capabilities to NPV. FCoE NPV connectivity from an FCoE NPV bridge to the FCF is supported over point-to-point links, and FCF can be up to three hops away.
