25 VMs are running on a Hyper-V platform at a remote office (ROBO). The administrator has been tasked with setting up replication to the main office (HQ) so it can act as the disaster recovery site. The available bandwidth is 20 Mbps. RPO is set to four hours and the data generated for the interval is 100 GB. Which of the following will achieve the RPO?
To achieve a Recovery Point Objective (RPO) of four hours when replicating 100 GB of data with a bandwidth of 20 Mbps, using WAN acceleration is the most feasible solution. WAN acceleration optimizes the data transfer over the available bandwidth, making it possible to replicate the required data within the given time frame. Configuring the replication jobs to use WAN acceleration and setting the schedule to run every four hours ensures that the data can be transferred efficiently, meeting the RPO requirement.
There is no mention of "interval copy" in the documentation. Additionally, the amount of data to be processed in the amount of time is not possible without WAN accelerators: 4 hours = 14400 seconds 20Mbps = ~2.5MB/s Max datatransfer would be 14400 x 2.5 = 36000MB Required transfer is 102400MB So C seems the best answer.
Why not C?
Answer: C http://rps.dewin.me/bandwidth/ it's impossible move 100 GB in 4 hours!
impossible to move 100GB in 4 hours without a "trick"=wan accel
C is the correct
