   Why is it important to distinguish between repair MTTR and recovery MTTR in disaster recovery planning?

   • ARepair MTTR is always longer than recovery MTTR
   • BRecovery MTTR includes broader restoration steps such as data recovery and failover, which are not part of simple component repair
   • CRecovery MTTR is used for hardware failures, while repair MTTR is used for software failures
   • DThey are the same metric and do not need to be distinguished

   A security engineering manager is developing a cost estimate for a new security operations center. The manager has historical data from three similar projects with costs of $1.2M, $1.5M, and $1.8M. The new project is expected to be 20% larger in scope. The manager also has a detailed list of required personnel and their loaded rates. Which estimation approach would provide the most defensible estimate?

   • AUse parametric estimation based on cost per square foot
   • BUse the average historical cost and add 20%
   • CUse bottom-up estimation by summing detailed personnel and material costs
   • DUse the highest historical cost as a conservative estimate
