350-601 Question #712: Real Exam Question with Answer & Explanation

Question

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

Options

• AUse TE ports to connect to upstream switches.
• BAdd a port channel to upstream switches.
• CConfigure the NPV devices to use an external FLOGI database.
• DConnect the NPV devices to multiple upstream switches.

Explanation

To enable fabric redundancy for an NPV mode Cisco MDS 9000 Series Switch, implementing a Fibre Channel port channel to the upstream switches aggregates multiple links. This provides link-level redundancy and increased bandwidth to the core fabric.

Common mistakes.

• A. 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.
• C. 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.
• D. 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.
