Testing the reset functionality of an OLT board ensures that the board can recover from failures or configuration changes.
Methods for Testing Reset :
Hot Swap : Physically removing and reinserting the board tests its ability to initialize and function after a reset.
RESET Button : Pressing the physical RESET button on the board forces a hardware reset, verifying recovery capabilities.
Reset Command : Using CLI commands (e.g., reset board) resets the board remotely, allowing verification of software-based recovery.
Why D?
All three methods are valid ways to test the reset functionality of an OLT board. Each method addresses different scenarios and ensures comprehensive testing.
Thus, the correct answer is D .
