1.
Which of the following is the most prominent and used tool in the Big Data industry with its enormous capability of large-scale processing data?
Correct Answer
D. Hadoop
Explanation
Hadoop is the most prominent and used tool in the big data industry due to its enormous capability of large-scale processing data. It is an open-source framework that allows for distributed storage and processing of large datasets across computer clusters. Hadoop's distributed file system (HDFS) enables data to be stored and processed across multiple machines, while its MapReduce programming model allows for parallel processing of data. With its scalability, fault tolerance, and ability to handle vast amounts of data, Hadoop has become the go-to tool for big data processing.
2.
Which of the following is flexible to work with HDFS as well as with other data stores?
Correct Answer
C. Apache Spark
Explanation
Apache Spark is flexible to work with HDFS as well as with other data stores. Spark provides a unified analytics engine that supports various data processing tasks, including batch processing, streaming, machine learning, and graph processing. It can seamlessly integrate with Hadoop and HDFS, allowing users to leverage their existing Hadoop clusters and data stored in HDFS. Additionally, Spark also supports other data sources such as Cassandra, MongoDB, Amazon S3, and more, making it a versatile choice for data processing and analytics across different data stores.
3.
Which of the following has this unique feature, ‘massive scalability’?
Correct Answer
B. Apache Storm
Explanation
Apache Storm has the unique feature of "massive scalability". Apache Storm is a distributed real-time computation system that allows for processing large amounts of data in a scalable and fault-tolerant manner. It is designed to handle high velocity streaming data and can scale to handle large workloads by distributing the processing across multiple nodes in a cluster. This makes it an ideal choice for applications that require real-time data processing and have high scalability requirements.
4.
Which of the following mainly processes data sets?
Correct Answer
A. Cassandra
Explanation
Cassandra is a distributed database management system that is designed to handle large amounts of data across multiple servers. It is mainly used for processing and storing data sets, making it the correct answer for this question. Apache Storm, Apache Spark, and Hadoop are also used for processing big data, but they have different functionalities and purposes compared to Cassandra.
5.
Which of the following follows a client/server model where the server could be located on-premise?
Correct Answer
A. RapidMiner
Explanation
RapidMiner follows a client/server model where the server can be located on-premise. This means that the software can be installed on a local server within an organization's infrastructure, allowing for greater control and security over the data being processed and analyzed. The client, or user interface, can then connect to the server to access and utilize the data mining and analytics capabilities of RapidMiner. This client/server model is beneficial for organizations that prefer to keep their data and analysis processes within their own network rather than relying on cloud-based solutions.
6.
Which of the following is ideal for the business that needs fast and real-time data for instant decisions?
Correct Answer
B. MongoDB
Explanation
MongoDB is ideal for a business that needs fast and real-time data for instant decisions because it is a NoSQL database that offers high performance and scalability. It allows for the storage and retrieval of large volumes of data in real-time, making it suitable for applications that require quick access to data for decision-making. MongoDB's flexible document model and distributed architecture enable it to handle high-speed data processing, making it a suitable choice for businesses that need fast and real-time data analysis.
7.
Which data tool allows for one not to necessarily be a statistical expert before it can be made use of although used for statistical analysis?
Correct Answer
C. R Programming Tool
Explanation
R Programming Tool allows for one not to necessarily be a statistical expert before it can be made use of although used for statistical analysis. R is a programming language and software environment specifically designed for statistical computing and graphics. It provides a wide range of statistical and graphical techniques, making it accessible for users with varying levels of statistical expertise.
8.
Which data tool does one need to deal with large volumes of network data or graph-related issues like social networking or demographic patterns?
Correct Answer
D. Neo4j
Explanation
Neo4j is the correct answer because it is a data tool specifically designed to handle large volumes of network data or graph-related issues. It is a graph database that allows for efficient storage, retrieval, and analysis of interconnected data, making it ideal for tasks such as analyzing social networks or demographic patterns. RapidMiner, MongoDB, and R Programming Tool are not specifically designed for handling network data or graph-related issues, making them incorrect choices.
9.
Which data tool is regarded as being very necessary before stepping into the Big Data industry?
Correct Answer
C. Hadoop
Explanation
Hadoop is regarded as being very necessary before stepping into the big data industry. Hadoop is an open-source framework that allows for the distributed processing of large datasets across clusters of computers. It provides a scalable and reliable platform for storing, managing, and analyzing big data. Hadoop's ability to handle large volumes of data, its fault-tolerance, and its ability to process data in parallel make it an essential tool for working with big data.
10.
What does HPCC stand for?
Correct Answer
A. High-Performance Computing Cluster
Explanation
HPCC stands for High-Performance Computing Cluster. This term refers to a group of computers connected together to work as a single system, providing high-performance computing capabilities. This cluster is designed to handle complex and computationally intensive tasks, such as scientific simulations, data analysis, and large-scale data processing. By harnessing the power of multiple computers working in parallel, HPCCs can significantly speed up calculations and improve overall performance.
