Choice "A" is correct. The arrangement that the controller would be looking for would be a cold site. The reason is the use of an alternate location (either a hot site or a cold site) and then the delivery of duplicate computer hardware (that makes it a cold site).
Choice "d" is incorrect. With a hot site, the hardware would already be on the floor at the alternate location and available for use. Nothing would have to be delivered, unless the organization had some company-specific hardware that was not included in the disaster recovery contract. If so, that hardware would have to be delivered to the alternate location.
Choice "c" is incorrect. There should certainly be written procedures for the use of the back-up site, but that is not the name of the arrangement. There may or may not be written procedures.
Choice "b" is incorrect. This is not a commonly used term to describe disaster recovery facilities.
