Single Answer
0Which of the following best describes replication as a resilience strategy?
Answer Options
A
It makes a complete backup copy of live data that can be restored from media if needed, then journaled changes can be replayed to catch up to the moment of failure.
B
It creates a continuous copy of live data either asynchronously or synchronously.
C
It uses a series of snapshots to provide disaster recovery for virtual machines.
D
It requires high-speed media to keep up with live data.
Correct Answer: B
Explanation
Replication can be synchronous or asynchronous but focuses on keeping an up-do-date copy of live data. It does not require high-speed media but does require storage media that is fast enough to keep up with the speed of change from the production environment. Replication does not rely on journaling or snapshots.
