In a small network, a single device failure may be inconvenient.

In an enterprise network, a single failure can stop:

• Business operations.
• Customer services.
• Communication systems.

Professional networks are designed with:

High Availability

High availability means keeping network services running even when failures occur.

The goal:

"No single failure should bring down the entire network."

Mission Objectives

By the end of this mission, students should understand:

• High availability concepts.
• Single points of failure.
• Link redundancy.
• EtherChannel.
• First Hop Redundancy Protocols.
