Which of the following ensures the availability of transactions in the event of a disaster?

A.
Send tapes hourly containing transactions offsite,

B.
Send tapes daily containing transactions offsite.

C.
Capture transactions to multiple storage devices.

D.
Transmit transactions offsite in real time.

Explanation:
The only way to ensure availability of all transactions is to perform a real-time transmission to an offsite facility.
Choices A and B are not in real time and, therefore, would not include all the transactions. Choice C does not
ensure availability at an offsite location.
