SG0-001 · Question #298
A Fibre Channel switch failed in your fabric and a replacement switch has been delivered. Which two (2) actions should be taken before plugging the replacement switch into the fabric? (Choose two.)
The correct answer is C. Delete the zone configuration information on the replacement switch. D. Set the Domain ID of the replacement switch to the Domain ID of the failed switch.. Before integrating a replacement Fibre Channel switch into an existing fabric, its zone configuration should be cleared, and its Domain ID should be set to match that of the failed switch to ensure seamless integration and operational consistency.

Why each option
Before integrating a replacement Fibre Channel switch into an existing fabric, its zone configuration should be cleared, and its Domain ID should be set to match that of the failed switch to ensure seamless integration and operational consistency.
Deleting the fabric records of the old switch is typically a cleanup action performed after the new switch is fully operational and recognized by the fabric, not a prerequisite for plugging in the replacement.
Configuring the new switch into the current zone configuration is an action performed *after* the switch has joined the fabric and obtained its identity, not *before* physically connecting it.
Deleting the zone configuration information on the replacement switch ensures it enters the fabric with a clean slate, preventing any pre-existing or default zoning rules from conflicting with the fabric's established zoning policies and causing unexpected connectivity issues.
Setting the Domain ID of the replacement switch to match the failed switch's Domain ID is crucial for the fabric to recognize it as a direct replacement, maintaining the fabric topology, routing tables, and zoning rules without requiring extensive reconfigurations across the entire fabric.
