An application deployed to CloudHub with two workers keeps a running total in an Object Store, and each worker reports a different figure. What explains that difference?

選択肢

1. The total sits in a store whose capacity is smaller than the number of entries the workers write.
2. The total sits in a store whose entries expire sooner than the workers manage to read them back.
3. The total sits in a store that each worker clears on a schedule rather than one the workers keep filled.
4. The total sits in a store that each worker holds on its own rather than one the workers have in common.
