1.Question 1Which is a processing unit of Hadoop and an important core component of the Hadoop framework?1 pointMapReduceHadoop CommonYet Another Resource Negotiator (YARN)Hadoop Distributed File System (HDFS)2.Question 2Which of the following components are included in Hadoop? Select all that apply.1 pointMapReduceYet Another Resource Negotiator (YARN)Hadoop Distributed File System (HDFS)Apache Cassandra3.Question 3What is the default block size in Hadoop?1 point200 megabytes132 megabytes126 megabytes128 megabytes4.Question 4Which statement is true regarding the comparison between traditional RDBMS and Apache Hive?1 pointTraditional RDBMS always have built-in support for data partitioning, whereas Hive does not support partitioning. Traditional RDBMS is based on the write once, read many methodologies. Hive allows for as many read operations and write operations as a user needs.Traditional RDBMS is used to maintain a data warehouse. Hive is used to maintain a database and uses the structured query language known as SQL. Traditional RDBMS can handle up to terabytes of data. Hive is designed to handle petabytes of data.5.Question 5Which component of HBase is a centralized service for maintaining configuration information to maintain healthy links between nodes?1 pointRegion ServersRegionZooKeeperHMaster6.Question 6Which of the following statements is true with reference to Hive?1 pointJDBC clients allows Java applications based on ODBC to connect to Hive.ODBC client allows applications based on JDBC clients to connect to Hive.JDBC clients allow application based on ODBC to connect to Hive.ODBC clients allow Java applications to connect to Hive.7.Question 7Which of the following is a feature of Hadoop Distributed File System (HDFS)?1 pointOne cluster can be scaled into hundreds of nodesNeeds permissions to move across multiple platformsIf one machine crashes, the data needs to be rebuilt againCan store up to megabytes of data8.Question 8What is Yet Another Resource Navigator (YARN)?1 pointData processing frameworkStorage layer in HadoopData migration toolResource Manager
