Eventual consistency does NOT guarantee that:Question 20Select one:A.The system is always consistent at all timesB.All processes see the same data version eventuallyC.Each process will see the same version of the data item immediatelyD.There is no inconsistency windowE.The data is replicated across different nodes

In a strong consistency model, what do users see regarding data?a.No consistency guaranteesb.Temporary inconsistenciesc.Absolute consistency with the most recent writed.Different data at different times

Which of the following is/are correct?Question 5Select one or more:Select one or more:a.Eventual consistency ensures that data is eventually consistent in a distributed database system. Thus, no any read-write conflicts and write-write conflicts can occur under eventual consistency.b.Under eventual consistency, all servers eventually "converge" to the same state at some point in future.c.Eventual consistency does not order concurrent writes as they are executed.d.Eventual consistency guarantees that, if updates are made to a given data item, all reads to that item will return the same value.

For the consistency property of database transactions, it requires that the state of a database is consistent before and after each transaction, but the intermediate states of a database during a transaction do not need to be consistent.

In a distributed database system, which approach is used to ensure that all copies of a data item are updated simultaneously?Immediate consistencyEventual consistencyQuorum consensusSerializability

In a scenario without concurrency control, what problem might arise when two transactions try to update the same data simultaneously?Reduce data consistencyImproved data consistency
