remote site at the same time.

9. C. Redundant systems/components provide protection against the
failure of one particular piece of hardware.

10. B. During the business impact assessment phase, you must identify
the business priorities of your organization to assist with the
allocation of BCP resources. You can use this same information to
drive the DRP business unit prioritization.

11. C. The cold site contains none of the equipment necessary to
restore operations. All of the equipment must be brought in and

configured and data must be restored to it before operations can
commence. This often takes weeks.

12. C. Warm sites typically take about 12 hours to activate from the
time a disaster is declared. This is compared to the relatively
instantaneous activation of a hot site and the lengthy time (at least
a week) required to bring a cold site to operational status.

13. D. Warm sites and hot sites both contain workstations, servers, and
the communications circuits necessary to achieve operational

status. The main difference between the two alternatives is the fact
that hot sites contain near-real-time copies of the operational data
and warm sites require the restoration of data from backup.

14. D. Remote mirroring is the only backup option in which a live
backup server at a remote site maintains a bit-for-bit copy of the
contents of the primary server, synchronized as closely as the
latency in the link between primary and remote systems will allow.

15. A. The executive summary provides a high-level view of the entire
organization’s disaster recovery efforts. This document is useful for
the managers and leaders of the firm as well as public relations
personnel who need a nontechnical perspective on this complex
effort.

16. D. Software escrow agreements place the application source code

in the hands of an independent third party, thus providing firms
with a “safety net” in the event a developer goes out of business or
fails to honor the terms of a service agreement.
