What is a major disadvantage of having multiple, isolated copies of data?

Group of answer choices

The data is likely to have integrity problems because changing it in one place will likely not result in it being changed elsewhere

The data will take up so much space across company resources that it is unlikely there will be any computer storage space available for anything else

The bandwidth requirements of automatic synchronization between the different copies of data may result in your network being overloaded to the point of failure during heavy activity periods

With multiple copies of the data it is almost certain that a hacker will steal one of them unnoticed
