The correct answer is B. False. B (False) is correct because 15 Mbit/s is far too low to transfer 32 GB in 2 hours at 80% utilization. The math: 32 GB = 256,000 Mbits; dividing by 7,200 seconds gives ~35.6 Mbit/s raw throughput required; accounting for only 80% utilization, you actually need ~44.4 Mbit/s of…
Question
A company plans to use remote to protect data between site A and site B. 32GB of production, data needs to be transferred from site A to site B within 2 hours with bandwidth utilization of about 80%. For the bandwidth between the two sites (not considering duplication and compression), 15 Mbit/s is the best choice.

Explanation
B (False) is correct because 15 Mbit/s is far too low to transfer 32 GB in 2 hours at 80% utilization. The math: 32 GB = 256,000 Mbits; dividing by 7,200 seconds gives ~35.6 Mbit/s raw throughput required; accounting for only 80% utilization, you actually need ~44.4 Mbit/s of total bandwidth - roughly 3× more than 15 Mbit/s. At 15 Mbit/s with 80% utilization, you'd only move about 10.5 GB in 2 hours, leaving 21.5 GB untransferred. Option A is wrong simply because the arithmetic does not support the claim.
Memory tip: Use the formula Required Bandwidth = (Data Size in Mbits) ÷ (Time in seconds) ÷ (Utilization %) - remember to convert GB → Gbits → Mbits first, and then divide by the utilization rate (not multiply) since utilization limits how much of your bandwidth is usable.
