Explanation:
The RAID Advisory Board has defined three classifications of RAID: Failure Resistant Disk Systems (FRDSs), Failure Tolerant Disk Systems, and Disaster Tolerant Disk Systems. As of this writing only the first one, FRDS, is an existing standard, and the others are still pending. We will now discuss the various implementation levels of an FRDS.
Failure Resistant Disk System: The basic function of an FRDS is to protect file servers from data loss and a loss of availability due to disk failure. It provides the ability to reconstruct the contents of a failed disk onto a replacement disk and provides the added protection against data loss due to the failure of many hardware parts of the server. One feature of an FRDS is that it enables the continuous monitoring of these parts and the alerting of their failure.
Failure Resistant Disk System Plus: An update to the FRDS standard is called FRDS+. This update adds the ability to automatically hot swap (swapping while the server is still running) failed disks. It also adds protection against environmental hazards (such as temperature, out-of-range conditions, and external power failure) and includes a series of alarms and warnings of these failures.
Incorrect Answers:
B: Foreign Resistant Disk Systems is not one of the three classifications of RAID identified by the RAID Advisory Board.
C: File Transfer Disk Systems is not one of the three classifications of RAID identified by the RAID Advisory Board.
D: Federal Resistant Disk Systems is not one of the three classifications of RAID identified by the RAID Advisory Board.

Explanation:
A risk assessment is a critical part of the disaster recovery planning process. In disaster recovery planning, once you've completed a business impact analysis (BIA), the next step is to perform a risk assessment.
Once risks and vulnerabilities have been identified, i.e. after the risk assessment has been completed, four types of defensive responses can be considered:
Protective measures
Mitigation measures
Recovery activities
Contingency plans
Incorrect Answers:
B: Contingency plans depend on risk assessments, not on residual risks. The residual risk is remaining risk after the security controls have been applied.
C: Contingency plans depend on risk assessments, not on Security controls.
D: Contingency plans depend on risk assessments, not on Business units.
