A data store is said to provide read-your-writes consistency if a read operation is always completed before a successive write operation by the same process. a. true b. false Objects encapsulate data and operations on that data, so they cannot be safely replicated. a. true b. false In general, a data store is said to be sequentially consistent when it satisfies the following condition: The result of any execution is the same as if the (read and write) operations by all processes on the data store were executed in some sequential order and the operations of each individual process appear in this sequence in the order specified by its program. a. true b. false Client-initiated replicas are more commonly known as (client) caches. In essence, a cache is a local storage facility that is used by a client to temporarily store a copy of the data it has just requested. a. true b. false Multicasting is best with pull-based approaches. a. true b. false
