CISM study material · question 968 of 1000

What is concurrent processing in NIST's reconstitution guidance?

  1. Running the recovery and the reconstitution activities at the same time as one another rather than in any strict sequence at all
  2. Running the system at two locations at once until there is assurance the recovered system works correctly and securely
  3. Processing backlogged transactions alongside live ones
  4. Restoring several of the systems in parallel with one another in order to shorten the overall recovery window that results from it
Show the answer

Answer: B. Running the system at two locations at once until there is assurance the recovered system works correctly and securely

SP 800-34r1 defines it as running the system in two places at the same time until the recovered one has proved it works properly and securely.
