Question

which advantage of stored digital data could be a disadvantage in some circumstances?
a. after several copies are made, stored digital data remain identical.
b. all types of information can be passed on to receivers of the data.
c. stored digital data can be completely protected from viruses and hackers.
d. the data are stored reliably.

Explanation:

1. Option A: The ability to make identical copies is generally an advantage. But in cases of data security breaches, identical copies mean multiple copies of sensitive data can be accessed by unauthorized parties.
2. Option B: Passing on all - types of information is an advantage for data sharing, not a disadvantage in most cases.
3. Option C: Stored digital data cannot be completely protected from viruses and hackers, so this is not an advantage in the first place.
4. Option D: Reliable storage is an advantage and not a disadvantage.

Answer:

A. After several copies are made, stored digital data remain identical.
