Capital Analytics, a digital marketing research firm, plans to move its research archives to a Hadoop cluster. They have a Hadoop cluster configuration with 1 NameNode and 3 DataNode(s).

For a replication factor of 3 and the data block size of 128 MB, what will happen if we store a file called '2010_archive' that is 150 MB in size?

(Select all acceptable answers.)

The '2010_archive' file will be split into 2 blocks.
Metadata for the '2010_archive' file will be stored with the DataNode(s).
Metadata information at the NameNode will remain unchanged if we increase the replication factor from 3 to 5.
Failure of any one DataNode will result in the loss of data from the '2010_archive' file.
All requests to read/write files to the cluster will be received by the given single NameNode.
