 Data definition is the process of creating, modifying, or deleting the structure and objects of a database, such as tables, fields, indexes, and views. Data definition is performed using data definition language (DDL), which is a subset of SQL commands. An administrator can use DDL to grant or revoke permissions for a user to access data in a database. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 144.

172.16.2.189 is a valid IP address that a technician can assign to a new desktop computer. An IP address is a unique identifier that is assigned to a device on a network that uses the Internet Protocol (IP). An IP address consists of four numbers separated by dots, each ranging from 0 to 255. For example, 192.168.1.1 is an IP address. An IP address can be classified into different classes based on the first number: Class A (1-126), Class B (128-191), Class C (192-223), Class D (224-239), and Class E (240-255). Each class has a different range of IP addresses that can be used for public or private networks. 172.16.2.189 is a Class B IP address that belongs to the private network range of 172.16.0.0 to 172.31.255.255. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 165.

The most important element for data reports to have value is the inclusion of useful metrics. Metrics that are relevant and appropriately targeted provide actionable insights and support decision-making processes. Large sample sizes, daily data, and frequent measurements contribute to data quality and detail but are only valuable if the data being measured is meaningful and aligned with the objectives of the analysis.

A managed relational database is a type of database that is hosted and maintained by a cloud service provider such as Microsoft Azure or Amazon Web Services. A relational database is a type of database that organizes data into tables that are related to each other by common fields or attributes. A managed relational database would be the best option for allowing multiple users to create and edit reports at the same time because it can handle concurrent user requests, provide high availability and scalability, and perform complex queries and operations on the data. A text file on a shared drive, an informational intranet page, and locally installed productivity software are not options that can allow multiple users to create and edit reports at the same time because they cannot handle concurrent user requests, provide high availability and scalability, or perform complex queries and operations on the data. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals, page 197.
