What are the 3 main entities of the GFS architecture?

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

• To replace all existing file systems on Google's servers.

• To provide a highly reliable and scalable distributed file system for Google's computing infrastructure.

• To create a file system exclusively for Google's end-user devices.

• To implement a file system with the highest possible data compression ratio.

How does GFS achieve fault tolerance and data reliability?

• By making regular backups of all data.

• By replicating data across multiple distributed servers.

• By compressing data to minimize storage requirements.

• By using a centralized file server.

What is a Chunkserver in the Google File System?

• A server responsible for web hosting.

• A server that stores a single, fixed-size data unit called a chunk.

• A server that manages user authentication.

• A server that performs data compression.

In the Google File System, what is the role of the Master server?

• To store user data.

• To serve web pages to end-users.

• To manage file metadata and coordinate access to data stored in Chunkservers.

• To provide search engine functionality.

In GFS, what is the primary motivation behind using data replication?

• To reduce storage costs

• To enhance data security

• To improve data availability

• To minimize the need for data compression

Which of the following is NOT a design goal of the Google File System?

• High availability

• High throughput for large files

• Low latency for small files

• Data encryption for security

What are the 2 types of nodes available in HDFS?
