What does the term "NoSQL" actually mean?

Correct! Wrong!

The effective meaning of "NoSQL" is: It is not limited to relational database technology. NoSQL stands for "Not Only SQL" or "Non-Relational," and it refers to a class of database management systems that do not strictly adhere to the traditional relational database model. NoSQL databases provide an alternative approach to storing and retrieving data, and they are designed to handle large volumes of unstructured, semi-structured, or structured data more efficiently than traditional relational databases.

Millions of people use a large telecommunications provider. Most of their clients pay in advance. They can very quickly move to other vendors because they are prepaid clients. This business has experienced some significant customer loss due to competition over the last four to six months. They want to create a system that can provide them access to the social network of their clients (e.g. who is the influencer and who is the follower). Additionally, they want the system to be educated over time to anticipate potential complaints and the capability to analyze voice and data consumption patterns in real time. Which of the following would you advise in this situation?

Correct! Wrong!

Apache Spark is a powerful big data processing engine that provides fast and distributed data processing capabilities. It is designed to handle large-scale data analytics and is well-suited for real-time data processing, machine learning, and stream processing.

Which of the following describes network congestion evidence?

Which of the following describes network congestion evidence?

Different degrees of Service Level Agreements (SLAs) definition exist. Which of the following is NOT a valid level?

Correct! Wrong!

Service Level Agreements (SLAs) are contracts or agreements between a service provider and its customers that define the expected level of service and the metrics that will be used to measure the performance of the service. SLAs can be defined at different levels, but "Multilevel SLA" is not a recognized or standard term.

Which of the Big SQL-related statements below is TRUE?

Correct! Wrong!

IBM Big SQL is a technology that provides SQL access to data stored in Hadoop-based systems, such as HDFS (Hadoop Distributed File System) and HBase. It allows users to run SQL queries on their Hadoop data, making it easier for users who are familiar with SQL to interact with large-scale distributed data. Big SQL supports updates in Hive. Hive is another technology in the Hadoop ecosystem that provides a SQL-like interface to query and manage data stored in Hadoop. While Hive's traditional behavior is read-only, it introduced ACID (Atomicity, Consistency, Isolation, Durability) support for tables using the ORC (Optimized Row Columnar) file format. With ACID support, Hive allows for updates, inserts, and deletes on certain types of tables.

Data in motion is information that is continuously being added to. Which of the following can be used to import this kind of data into the distributed file system?

Correct! Wrong!

Flume is a distributed data collection service provided by the Apache Hadoop ecosystem. It is designed to efficiently collect, aggregate, and move large amounts of streaming data (data in motion) from various sources into Hadoop's distributed file system (HDFS) for further processing and analysis. Flume supports a wide range of data sources, including log files, social media feeds, sensors, and more.

Which of the following big data elements decides whether to replicate blocks at all?

Correct! Wrong!

The NameNode is the component in Hadoop Distributed File System (HDFS) that makes all decisions regarding the replication of blocks. It is the master node responsible for managing the file system namespace and metadata, including tracking the location and replication status of each block in the cluster.

What example of unstructured data is NOT one of the ones listed below?

Correct! Wrong!

Netezza table is a data warehouse appliance that uses a columnar storage format. It stores structured data in columns and rows, making it a structured data storage solution.

A telecommunications company has a high rate of customer turnover. More than five million people use them. Each year, they have more than 400 terabytes of call detail records. Since the majority of their clients are prepaid, they are always free to switch telecom companies. They seek to comprehend client behavior in order to correct the situation. They intend to create a unique profile for each customer as a result. Additionally, they want to add social media information to the profile to enhance it. Which of the following would you advise, given these conditions?

Correct! Wrong!

Hadoop is an open-source big data processing framework that excels at handling large volumes of data, making it well-suited for analyzing vast amounts of call detail records and customer data.

To analyze client sales data and forecast which products will sell better, you must set up a Hadoop cluster. Which of the following options will allow you to build up your cluster with the highest platform stability?

Correct! Wrong!

For the most stable and reliable platform to provision a Hadoop cluster for data analysis on customer sales data, it is recommended to leverage the Open Data Platform (ODP) core. The ODP core provides a standardized and consistent foundation for Hadoop distributions, reducing compatibility risks and ensuring a stable environment for data analysis tasks. This allows you to focus on analyzing customer sales data and predicting product popularity with confidence, without worrying about integration complexities or the maintenance burden of a custom-built platform. Using the ODP core also increases the likelihood of interoperability with other Hadoop distributions that adhere to the ODP standards, providing more flexibility for future expansion and integration with other data systems.
