What are some of the characteristics of systems that use Active Replication (choose 2)?
1. replicas are partially initialized, and may have some processing state in preparation for failure
2. replicas are entirely initialized subsequent to failures
3. Achieves the strongest form of high availability
4. replicas actively and completely share the processing state between the tightly-coupled components
5. replication occures at a pre scheduled time.
Please make comments and help me to clarify the topic
Thanks
Ruilin
