15 VMs are running on a Hyper-V platform and five physical servers at a remote office (ROBO). The administrator has been tasked with setting up centralized off-site backups at the headquarters (HQ). The available bandwidth is 50 Mbps. RPO is set to six hours and the data generated for the interval is 500 GB. WAN accelerators can be added if necessary. Which of the following will achieve the RPO?

A. Use backup copy jobs in with High-Performance Mode enabled. Set the schedule to run every six hours.
B. Use backup copy jobs with copy mode set to "immediate copy". Use WAN acceleration.
C. Use backup copy jobs with copy mode set to "periodic copy" and copy every six hours.
D. Configure the backup copy jobs with traffic throttling to 30 Mbps to limit the impact. Enable WAN acceleration.
