$3.$ In another department of company ABC, the virtual server VM is running on a physical server SH and is pulling data from server DB$.$ Senior management has determined the MTD for the department's business process is $8$ hours. The recovery of virtual server VM is dependent on physical server PS being recovered first. Unlike the VM dependency, server DB does not have a dependency, so it can be recovered at the same time as PS$.$

a$.$ let's assume the recovery time for each system is as follows: PS is $4$ hours, VM is $2$ hours, and DB is $3$ hours. What is RTO for the combined business process? Is this an acceptable RTO?
