Which is a benefit of dynamic tracking of Fibre Channel devices?
The correct answer is B. SAN changes are automatically detected. Dynamic tracking of Fibre Channel devices in AIX allows the system to automatically detect and reflect changes in the SAN topology without manual reconfiguration or reboots.
Question
Which is a benefit of dynamic tracking of Fibre Channel devices?
Options

Why each option
Dynamic tracking of Fibre Channel devices in AIX allows the system to automatically detect and reflect changes in the SAN topology without manual reconfiguration or reboots.
Preventing I/O failures with Fibre Channel tape devices is a function of error recovery and reservation policies, not dynamic tracking.
Dynamic tracking continuously monitors the Fibre Channel SAN fabric for topology changes such as device additions, removals, or path modifications. When changes occur, AIX automatically updates the Object Data Manager (ODM) device configuration, eliminating the need for manual cfgmgr runs to recognize new or altered SAN devices.
Creating disk arrays with a common set of attributes is a storage management task unrelated to the dynamic tracking feature.
NPIV (N-Port ID Virtualization) support is a separate Fibre Channel adapter capability that is not enabled or added by dynamic tracking.
