Question: In an MCData service, when a user has an active MCData message store account and has activated lossless communication, what happens to deferred delivery when the user is offline?
Option 1: The MCData service will continue to use deferred delivery, storing data until the user comes online.
Option 2: The MCData service shall not use deferred delivery, ensuring immediate notification upon the user's return online.
Option 3: The MCData administrator is notified to manually handle the deferred delivery for the offline user.
Option 4: The temporary store's 'time to live' value is extended until the user comes back online.
Explanation: This is correct because, when a MCData user has an active account and lossless communication activated, the MCData service shall not use deferred delivery for offline users. This ensures no temporary storage, aligning with lossless communication principles emphasizing reliability and immediate handling.
