NoSQL refers to a non-SQL or non-relational Data Management System which provides a mechanism for retrieving and storing data. The main reason behind the popularity of NoSQL is its capability to store and handle structured, semi-structured, unstructured, and polymorphic data. NoSQL is hugely popular in Big data and real-time web apps, which is increasing firmly. For example, companies like Google, Twitter, and Facebook collect terabytes of user data daily. Let’s take a look at some of the interview questions on NoSQL.  \n[https://technologypoint. in/what-are-nosql-databases/](https://technologypoint. in/what-are-nosql-databases/)  \nLearning Objectives  \nThe learning objectives of t his blog include the following:  \n1 . A common understanding of NoSQL, its features, and how it is better than relational databases .  \n2 . Knowledge of CAP theorem, scal ability, and normalization in NoSQL.  \n3 . Understanding Big SQL, Impala, and Polyglot persistence in NoSQL.  \nThis article was published as a part of the Data Science Blogathon  .  \nTable of contents  \n Introduction  \n Multiple-Choice Interview Questions  \n Detailed Interview Questions  \n Conclusion  \nMultiple-Choice Interview Questions  \nQ1 . In the variety of NoSQL databases, choose which is the simplest one .  \n Key-value  \n Wide-column  \n Document  \n All of the above  \nAnswer: Key-value  \nExplanation: It is considered the simplest NoSQL database as it stores all items as an attribute name ( i. e. ,“key”) and its corresponding value that is easy to fetch.  \nQ2 . “S harding” a database across many server instances can be gained with  \n LAN  \n SAN  \n MAN  \n All of the above  \nAnswer: SAN  \nExplanation: In order to make hardware act as a single server we can easily achieve SAN and other complex arrangements .  \nQ3 . Choose the correct example of a wide-column store .  \n Cassandra  \n Riak  \n MongoDB  \n Red its  \nAnswer: Cassandra  \nExplanation: Databases like Cassandra and HBase are efficient to deal with queries over huge volumes of data and store that in the form of columns instead of rows .  \nQ4 . Which options are used to distribute different data across multiple servers?  \n Partitioning  \n Bucketing  \n S harding  \n None of the above  \nAnswer: S harding  \nExplanation: S harding is a popular process where a s hard key is used to split the data into ranges and distribute it across various shards .  \nQ5 . Having multiple machines for storing files, MongoDB can be used as a    , to take advantage of data replication and load-balancing features .  \n AMS  \n CMS  \n File System  \n None of the above  \nAnswer: AMS  \nExplanation: AMS can help by load balancing features and facilitates data replication .  \nQ6 . Choose the correct type of NoSQL database .  \n SQL  \n Document Databases  \n JSON  \n All of the above Answer: Document Databases  \nExplanation: In Document databases, the data is stored as a key value where every key pairs with a complex data structure(document) .  \nQ7 . MongoDB, a popular type of NoSQL, is used by many firms as   software to build websites and offer services .  \n Frontend  \n Backend  \n Proprietary  \n All of the above  \nAnswer: Backend  \nExplanation: MongoDB is the most popular NoSQL database, it stores data as a backend and helps frontend systems work.  \nQ8 . In NoSQL, we can use   to process batch data and perform aggregation operations .  \n Hive  \n MapReduce  \n Oozie  \n None of the above Answer: MapReduce  \nExplanation: MapReduce combines a mapper and reducer, which facilitates users with an aggregation framework.  \nQ9 . MongoDB does not support which of the following listed sorting techniques?  \n Collation  \n Collection  \n Heap  \n None of the above  \nAnswer: Collation  \nExplanation: The row key in Google Bigtable can’t use frequently updated identifiers as a data type to store data efficiently.  \nQ10 . In MongoDB, the Dynamic schema feature is used to make   easier for ","cbCain0hs4r01cKi","https://ap.wps.com/l/cbCain0hs4r01cKi","pdf",422174,11,"English","# Introduction\n# Multiple-Choice Interview Questions\n## Q1-Q16\n# Detailed Interview Questions\n# Conclusion","[{\"question\":\"What is NoSQL and why is it popular?\",\"answer\":\"NoSQL is described as a non-SQL, non-relational data management system.
