Which description of a FLOGI database I ?
The correct answer is B. it indicates the devices that connect directly to the switch. The FLOGI database records all devices that have performed a Fabric Login directly to the local switch, identifying directly attached N ports and NL ports.

Why each option
The FLOGI database records all devices that have performed a Fabric Login directly to the local switch, identifying directly attached N ports and NL ports.
VSAN status and operational state information is displayed by the 'show vsan' command, not by the FLOGI database, which is limited to device login records.
When an end device such as an HBA or storage port connects to a Fibre Channel switch, it performs a FLOGI to register with the fabric and receive a Fibre Channel ID (FCID). The FLOGI database on each switch maintains a record of all N ports and NL ports that are directly attached and have completed this login process, making it specific to locally connected devices only.
Zone configuration and port membership on a local switch is viewed with the 'show zone' command, which is separate from the FLOGI database.
The FLOGI database is local to each individual switch and does not traverse VSANs; fabric-wide device information is tracked in the Fibre Channel Name Server (FCNS) database instead.
