What are the four key computing resources used in Big Data platforms?

• CPU, Memory, Storage, Network

• RAM, Disk, Cache, OS

• Processor, Disk, Software, Network

• RAM, Processor, Applications, Databases

What is multithreading in the context of processing nodes?

• Running multiple processes in different systems.

• Running multiple tasks simultaneously in a single core.

• Running multiple tasks simultaneously using multiple cores.

• Running a single task across multiple processors.

Why can't single-node computers easily accommodate massive amounts of data?

• They lack multithreading capabilities.

• They have limited capacity for processing and memory.

• They cannot connect to the network.

• They are not equipped with GPUs.

What does the Hadoop Distributed File System (HDFS) use to provide fault tolerance?

• Metadata storage

• Multithreading

• Data replication

• Job scheduling

In HDFS, what manages the metadata about files and their changes?

• Data nodes

• Name node

• TaskTracker

• JobTracker

What is the primary purpose of data replication in HDFS?

• To improve data integrity.

• To reduce file creation time.

• To provide fault tolerance.

• To increase network efficiency.

What is a key function of the JobTracker in MapReduce?

• Managing the data nodes.

• Scheduling tasks and tracking their progress.

• Handling data replication.

• Maintaining file system integrity.

Which framework introduced a new generation of job scheduling in Hadoop?

• MapReduce

• HDFS

• YARN

• TaskTracker

What type of data replication does HDFS support to maintain fault tolerance?

• Vertical

• Incremental

• Multiple copies

• Continuous snapshots

What is the primary purpose of the NameNode in HDFS?

• To execute jobs.

• To replicate data blocks.

• To manage file system metadata.

• To schedule tasks across clusters.
