Section BAttempt any three o f t h e f o l l o w i n g : 3 x 10 = 30
- aDistinguish between data anal ysis and reporting in the conte xt of Big Data. How does advanced analytics go beyond traditional reporti ng to uncover hidden patterns, trends, and correlations in data?
- bExplain Apache Hadoop and its role in big data processing. W hat are the core components of the Apache Hadoop ecosystem, and how do they work together to enable distributed data storage and processing?
- cExplain the core concepts of HDFS, including NameNode, DataN ode, and the file system namespace. How do these components work together to manage data storage and replication in Hadoop clusters?
- dDefine NoSQL databases. What are the key characteristics and benefits of NoSQL databases compared to traditional relational databases?
- eProvide an overview of Apache Hive architecture and its comp onents. How does Hive translate SQL-like queries into MapReduce jobs for data processing in Hadoop?
Section CAttempt any one p a r t o f t h e f o l l o w i n g : 1 x 10 = 10
- aDescribe the "5 Vs" of Big Data. What do each of these terms represent in the context of Big Data, and why are they essential considerations for data management and analysis?
- bProvide examples of real-world applications where Big Data a nalytics have been instrumental. How do industries such as healthcare, finance, e-commerce, and transportation leverage Big Data to gain insigh ts and create value?
- aDescribe the Hadoop Distribute d File System (HDFS). How does HDFS manage the storage and replication of data across a distributed cluster of machines?
- bDiscuss the process of devel oping a MapReduce application. W hat are the key steps involved in writi ng, testing, and deploying a Map Reduce program?
- aExplain how HDFS stores, reads, and writes files. Describe t he sequence of operations involved in storing a file in HDFS, retrieving da ta from HDFS, and writing data to HDFS
- bDescribe the considerations f or deploying Hadoop in a cloud environment. What are the advantages and challenges of running Hadoop clusters on cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Goo gle Cloud Platform (GCP)?
- aExplain the operations for creating, updating, and deleting documents in MongoDB. What are the MongoDB CRUD operations, and how are y used to manipulate data in collections?
- bDiscuss Resilient Distributed Datasets (RDDs) in Spark. What a r e RDDs, and how do they enable fault-tolerant and distributed dat a processing in Spark applications?
- aIntroduce the concepts of HBase and its role in the Hadoop e cosystem. How does HBase differ from traditi onal relational databases, and what advantages does it offer for storing and accessing large-scale data?
- bDiscuss the HiveQL language used in Apache Hive. How does Hi veQL support SQL-like syntax for defining tables, querying data, and performing data manipulation operations?
