The customer has built the necessary infrastructure at the remote site for application. What is the primary impact to the customer of a single hop SRDF/ AR solution when compared to SRDF/S in the event of failure at the primary production site?

A. Increased RIO with SRDF/S

B. Decreased RPO with SRDF/AR
