A company wants to minimize cost but still have a disaster recovery plan that allows quick recovery of critical systems. Which strategy best fits this requirement?
ABackup and restore with frequent backups
BPilot light with minimal core systems running
CWarm standby with full production environment running
DMulti-site active-active with load balancing
Step-by-Step Solution
Solution:
  1. Step 1: Analyze cost vs recovery speed

    Backup is cheapest but slowest recovery; warm standby and active-active are costly.
  2. Step 2: Identify pilot light benefits

    Pilot light keeps minimal systems running, balancing cost and faster recovery.
  3. Final Answer:

    Pilot light with minimal core systems running -> Option B
  4. Quick Check:

    Cost-effective quick recovery = Pilot light C [OK]
Quick Trick: Pilot light balances cost and recovery speed [OK]
Common Mistakes:
  • Choosing warm standby despite higher cost
  • Assuming backup is fast recovery
  • Confusing multi-site with cost-effective
