Two clients are attempting to write to a file, 'editors.txt', that already exists in GFS. Client A attempts to append \"Vim is the best editor!\" to a file, while client B, at the exact same moment, tries to write \"Emacs is better than vim!\" Client C, wanting to know which editor is the best, reads from the file soon after. What will they not see?  \na. \"Vim is the best editor!Emacs is better than vim!\"  \nb. \"Vim Emacs is is the better best than editor! vim!\"  \nc. \"Emacs is better than vim!Vim is the best editor!\"  \nd. \"Chickens love emacs!\"  \ne. All of the above are possible  \n2. Which of these would be the worst system to build on top of GFS?  \na. A high-transaction database system, with lots of small updates  \nb. A user file system, with folders, directories and small files  \nc. A map-reduce engine, with large streaming reads and writes  \nd. A cold (i.e. , long-term) storage system to backup/archive data  \ne. These are all terrible fits for GFS  \nQuestion 3-6 are based on the following storyline:  \nDaenerys Khaleesi, Mother of Dragons, is about to invade the Seven Kingdoms. Before the invasion begins, she wants to set up a system that will allow everyone outside of the seven kingdoms to watch her invasion. She has decided to partner with HBO, and they created KFSthe Khaleesi File System, which is very similar to GFS by Google.  \nKhaleesi has decided that she will edit the footage of her invasion to make it 10 hours long, resulting in 100 GB of video (10GB/hour) . Khaleesi has decided to use a chunk size of 100MB.  \nShe has 10 machines to work with, each of which have:  \n● CPU: 4 cores @ 3.7GHz  \n● Memory: 8 GB RAM  \n● Storage: 2 4TB drives, which can perform sustained reads at 200 MB/s each  \n● Network: 1 Gb/s network card  \n3.
