CISSP study material · question 139 of 500

A low-impact reporting system has a generous recovery time objective and a small budget. Which recovery approach does NIST SP 800-34 describe as proportionate?

  1. Server clustering with automatic failover across two data centres.
  2. A mirrored site with automated real-time replication.
  3. An alternate processing site held under commercial lease.
  4. A simple tape backup arrangement rather than a zero-downtime design.
Show the answer

Answer: D. A simple tape backup arrangement rather than a zero-downtime design.

SP 800-34 pairs immediate-recovery requirements with zero-downtime solutions and alternate sites, and a low-impact system with a longer objective with a less costly simple tape backup.
