Best fit? A: Hot site with replication. ## Revision Checklist - [ ] Define hot/warm/cold/cloud - [ ] Match to RTO/RPO ranges - [ ] Note reciprocal risks - [ ] Consider cloud DR factors ## Related [[Recovery Objectives (RTO, RPO, WRT, MTD)]] · [[Business Impact Analysis (BIA)]] · [[Business Continuity Planning (BCP) Overview]] · [[Service Level Agreements and Contracts]] · [[Data Retention and Destruction]] #cisSP #domain-1 #concept
