The MAIN reason for requiring that all computer clocks across an organization be synchronized is to:

A.
prevent omission or duplication of transactions.

B.
ensure smooth data transition from client machines to servers.

C.
ensure that e-mail messages have accurate time stamps.

D.
support the incident investigation process.

Explanation:
During an investigation of incidents, audit logs are used as evidence, and the time stamp information in them is
useful. If the clocks are not synchronized, investigations will be more difficult because a time line of events
might not be easily established. Time-stamping a transaction has nothing to do with the update itself. Therefore,
the possibility of omission or duplication of transactions does not exist. Data transfer has nothing to do with the
time stamp. While the time stamp on an e-mail may not be accurate, this is not a significant issue.
