QuestionQ176

Storage Network Design

What disadvantage does asynchronous storage replication have compared with synchronous storage replication in a disaster-recovery design?

  • A reduction in application performance
  • B distance limitations
  • C specific backup requirements
  • D potential data loss
Explanation

Asynchronous replication can have a nonzero recovery point objective because writes may not yet have reached the replica when the primary site fails. Those unreplicated writes can be lost.
