You work as a Security Administrator for uCertify Inc. You are working on a disaster recovery plan. According to the plan, the remote site B will hold a copy of data that is 2 hours behind the production data at site A. It will take 4 hours after a downtime at site A to decide to shift production to site B. An additional 40 minutes will be needed to bring up the network and redirect users so that the site B can become productive. What is the RPO of the plan?
