Which of the following is a disadvantage of replication?
Answer: C
Correct answer: Each site must have the same storage capacity.
A full copy of the database at every site means every site must be able to hold the whole thing, which can be a heavy requirement at a small location. The other three options are advantages of replication rather than disadvantages - less network traffic, resilience to the failure of one site, and local processing without network coordination.
