What is the proper calculation used to determine the bandwidth requirement for vSphere Replication?
A . VMs datastore size divided by the link speed
B . Peak data change rate within a Recovery Point Objective (RPO) period divided by the link speed
C . VMs datastore size divided by recovery time objective (RTO)
D . Average data change rate within a Recovery Point Objective (RPO) period divided by the link speed

View Answer

Answer: D

Explanation:

To determine the bandwidth that vSphere Replication requires to replicate virtual machines efficiently, you calculate the average data change rate within an RPO period divided by the link speed.
