NO.27 Which of the following statements about the alarm masking mechanism is TRUE?

The alarm masking mechanism makes sure that alarms are always present on the downstream interfaces to facilitate the troubleshooting process.

The alarm masking mechanism updates the events’ original time stamps when it masks/shows alarms, so that when an alarm is not masked anymore, the user can see the updated date and time associated with the original issue.

The alarm masking mechanism always forwards masked alarms to an external Network Management System (NMS) for alarm correlation.

The alarm masking mechanism preserves the events’ original time stamps, when related alarms gets hidden and then eventually displayed because of the mechanism itself, so that the user can still know the date and time of the original issue.
