CISM study material · question 946 of 1000

How does NIST recommend strict version control of the contingency plan be maintained?

  1. By publishing only electronic copies from a single repository
  2. By numbering each copy and auditing holders annually
  3. By requiring old plans or pages to be returned in exchange for new ones
  4. By reissuing the whole plan at each review
Show the answer

Answer: C. By requiring old plans or pages to be returned in exchange for new ones

SP 800-34r1 keeps versions straight by exchange: the coordinator hands out the new plan or pages only when the superseded ones come back, so old copies leave circulation.
