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.
