Which statement is correct about the information shown in the exhibit? Amnesiac (ttyu0) login:

The "Amnesiac" prompt signifies that the device has lost its configuration and reverted to a default state, which is typically the factory-default configuration, often occurring when the system cannot locate or load the primary configuration file. This state requires manual configuration or loading of a saved configuration.

A corrupted Junos OS would typically result in boot errors, kernel panics, or a non-functional device, not a specific "Amnesiac" login prompt.

A recent upgrade would show a standard login prompt for the new OS version, not an "Amnesiac" state, unless the upgrade process itself failed to save the configuration.

Memory corruption or a missing file system would lead to severe boot failures or system unresponsiveness, not the specific "Amnesiac" login prompt, which implies the OS is running but without a user-defined configuration.
