Question 12

+4.5 marksOne correct option

A server S requests to retrieve data from two data centers DC1DC_1 and DC2DC_2, which are located at distances of D1D_1 and D2D_2 meters respectively from the server S. The speed of data travelling through the medium that connects S with DC1DC_1 is m1m_1 m/sec and that connects S with DC2DC_2 is m2m_2 m/sec. With the given media for data transfer between S →DC1\rightarrow DC_1 and S →DC2\rightarrow DC_2, it takes an additional 200 milliseconds for the data to reach S from DC2DC_2 than it takes from DC1DC_1 if the complete response is ready only when the data is available to S from both the datacenters. Figure out the value of m2m_2 (in m/sec) in terms of D1D_1, D2D_2 and m1m_1. [Note: The data centers send responses only when they receive a request from the server]
