This is a follow-up to the previous question. Since you mentioned instance recovery in your last answer, the interviewer is asking a follow-up question to explore the topic in more detail.

"Instance recovery is the process of bringing back transactions which have not been written into the database at the moment of an instance failure. This ensures that no date is lost or duplicated in the database. Instance recoveries may be initiated due to hardware issues, power interruptions, or network outages."
