A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communication on the physical network segment. It is used to identify a specific piece of hardware, such as a network card or a network interface within a device. MAC addresses are crucial in ensuring the proper routing of data on local networks, functioning at the data link layer (Layer 2) of the OSI model.

A. A user is identified through user accounts, not hardware-level MAC addresses.

C. An IP address identifies devices on a network but operates at Layer 3 (Network Layer), while MAC addresses work at the hardware level.

D. A network is identified by an IP address or a subnet, not by a MAC address.

 A structured database is a type of database that stores data in tables and columns, where each column has a predefined data type and each row represents a record. Structured databases are also known as relational databases, because they use keys and relationships to link data across tables. Structured databases are ideal for placing financial data, because they offer the following advantages:

They are ACID compliant, which means they ensure the integrity, consistency, and reliability of transactions.

They support a range of data types, such as numbers, dates, strings, and currencies, which are suitable for storing and manipulating financial data.

They allow complex queries and calculations using SQL, which is a standard and widely used query language for financial analysis and reporting.

They are collaborative, secure, and stable, which are essential features for managing and sharing financial data among multiple users and applications.

Objects are a programming concept that represent entities or concepts in the real world. Objects have properties and attributes that describe their characteristics and behavior. For example, a car object may have properties such as color, model, speed, and fuel, and attributes such as engine, wheels, doors, and seats. Objects can also have methods, which are actions that the object can perform or that can be performed on the object. For example, a car object may have methods such as start, stop, accelerate, and brake. Objects are used to organize data and functionality in a modular and reusable way.

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.
