Google File System Quiz

What is the primary design goal of the Google File System (GFS)?

• High latency

• High reliability and scalability

• Low storage efficiency

• Complex architecture

In GFS, what is a 'chunk'?

• A large block of data typically 64 MB in size

• A small piece of metadata

• A network packet

• A directory entry

How does GFS ensure data reliability?

• By using RAID disks

• By replicating each chunk across multiple servers

• By performing real-time backups

• By using parity bits

What role does the GFS Master node play?

• It stores all the data

• It manages metadata and controls access to chunks

• It performs all read/write operations

• It balances network traffic

How does GFS handle large files efficiently?

• By compressing the files

• By splitting them into smaller chunks

• By storing them in a single large block

• By indexing all files

What happens when a chunk server in GFS fails?

• All data is lost

• The master node reallocates the lost chunks to other servers

• The entire file system crashes

• Data is automatically backed up

Which consistency model does GFS follow?

• Strong consistency

• Eventual consistency

• Weak consistency

• Consistent-on-write

How are writes and appends handled differently in GFS?

• Writes overwrite data; appends add data at the end

• Both operations are handled the same way

• Writes only happen at the beginning of the file

• Appends create a new file

Which programming model is GFS commonly associated with?

• MapReduce

• TensorFlow

• Hadoop

• Spark

How does GFS achieve fault tolerance?

• a) By using parity checks

• b) By maintaining multiple replicas of data chunks across different servers

• c) By compressing data

• d) By encrypting data
