An engineer must ensure fabric redundancy when implementing NPV mode on a Cisco MDS 9000 Series Switch. Which action enables fabric redundancy?

TE ports (Trunking E-Ports) are used for Inter-Switch Links (ISLs) between full Fibre Channel switches, not for connections from an NPV device, which uses NP-ports.

Adding a Fibre Channel port channel (FCPortChannel) between the NPV device and its upstream NPIV-enabled switches aggregates multiple physical links into a single logical link. This provides link-level redundancy and load balancing, ensuring that if one physical link fails, traffic can continue to flow over the remaining links, thus enhancing the overall fabric redundancy of the NPV connection to the core.

Configuring NPV devices to use an external FLOGI database is not a mechanism for achieving fabric redundancy; it relates to how device logins are managed.

While connecting to multiple upstream switches provides switch-level redundancy, a port channel specifically ensures link-level redundancy and bandwidth aggregation to the upstream fabric peer, which is a direct mechanism for fabric redundancy.
