problem1. Describe why making some replica managers read-only may enhance the performance of gossip system.
problem2. In gossip architecture, why does a replica manager need to keep both replica timestamp and value timestamp?
problem3. Illustrate why allowing backups to process read operations leads to sequentially consistent rather than linear executions in passive replication system.
problem4. What is the consistency issue increased by state transfer?
problem5. Illustrate why a multi-threaded server may not qualify as a state machine.
problem6. Illustrate what you understand by (i) “openness” and (ii) “Scalability” of distributed system
