Can anyone solve this for me?

Question 1: You want to store a 500MB file into a cluster with 12 nodes, which are located in four different racks (three nodes per rack). See Figure 1. 1. If a data block can store 256MB, how many data blocks are needed to split this file? 2. Use a replication factor of 3 and the write principles discussed earlier to allocate the data blocks into this cluster. To answer Q1, fill in the blanks in the following Table. Each Cell represents a data node Remember, you do not need to fill the cells. Rack | Rack 2 Rack 3 Rack 4 Question 2: Consider the block allocations shown in Figure 2. Using a replication factor of 3 , are all blocks allocated in the correct Rack and DataNode? If no, reallocate the blocks correctly. To answer Q2, fill in the blanks in the following Table. Each Cell represents a data node Remember, you do not need to fill the cells. Rack I Rack 2 Rack 3 Rack 4
