Suppose you are managing a cloud storage service where customers upload files for storage. A customer wants to store a file named "ProjectData.zip" in your cloud storage. The size of the file is 1.5TB. The cloud storage system uses a block-based storage mechanism similar to Hadoop, with a block size of 500GB and a replication factor of 2. Now answer the following questions: a) Calculate how many blocks will be created and what will be the size of each block.
