CISM study material · question 857 of 1000

What relationship does NIST describe between a disaster recovery plan and system contingency plans?

  1. The system contingency plans are what activate the disaster recovery plan, so the recovery of each of the individual systems is what decides whether the whole site itself has to be moved at all
  2. The two plans are alternatives to one another and only one of them is ever used, the choice depending on whether the disruption reached the facility or only the systems
  3. The disaster recovery plan replaces each of the system contingency plans for the duration of the relocation, and those plans resume only once the site has been returned
  4. The disaster recovery plan restores operability at the alternate site and may be supported by multiple system contingency plans recovering individual systems
Show the answer

Answer: D. The disaster recovery plan restores operability at the alternate site and may be supported by multiple system contingency plans recovering individual systems

SP 800-34r1 makes the disaster recovery plan system-focused on getting the target system, application or facility running at an alternate site, with several system contingency plans able to support it.
