Which of the following are characteristics of a transaction?

  • A.Atomicity
  • B.Durability
  • C.Isolation
  • D.All of the mentioned

Answer: D

Correct answer: All of the mentioned

The ACID properties are Atomicity (all or nothing), Consistency (the database moves from one valid state to another), Isolation (concurrent transactions do not see each other’s partial work) and Durability (a committed transaction survives a crash). All three listed are among them.
