Which two assumptions could the architect make when sizing the vROps cluster?

An architect is completing the physical design for a vRealize Operation (vROps) solution for a customer. The customer has only provided the following information for their existing environment:

– 500 Virtual Machines

– 2 VMware vCenter Servers

– 10 VMware vSphere Horsts

– 20 Datastores

– Live data should be stored within the vROps solution for 6 months

– The RTO for all existing management components is 4 hours

– The RTO for all existing management components is 1 hour

Which two assumptions could the architect make when sizing the vROps cluster? (Choose two.)
A . The vROps cluster will be configured as High Availability.
B . The RTO of the vROps solution will be 4 hours.
C . The resource profile of a virtual machine will be, on average, 1 vCPU and 2 GB RAM.
D . The minimum data retention within vRealize Operations Cluster will be 12 months.
E . The RPO of the vROps solution will be 1 hour.
