The remote replication feature is mainly used in disaster recovery and backup scenarios. Which of the following statements about the remote replication feature is correct:
I'm going with option A. If the replication link fails suddenly, the slave data will be unavailable, and that's just common sense. Unless, of course, the replication is being done by a team of superheroes.
Haha, option C is hilarious. As if anyone would choose asynchronous replication over synchronous for its 'peak bandwidth'! That's like choosing a Ferrari for its fuel efficiency.
Option B sounds like a good strategy. Being able to map the remote replication slave LUN to the host in advance can definitely help with faster business recovery.
I think option D is the correct answer. Synchronous remote replication is recommended for a disaster recovery solution with RPO=0, as it ensures zero data loss during failover.
