Satellite internet service is a type of internet service that uses satellites orbiting the earth to transmit and receive data signals from users’ devices. Satellite internet service can provide internet access to remote or rural areas where other types of internet service are not available or reliable. However, satellite internet service is also more susceptible to weather disruptions than other types of internet service, such as cable, DSL (digital subscriber line), or fiber. Weather conditions such as rain, snow, clouds, wind, or storms can interfere with the signal quality and strength between the satellite and the user’s device, causing slow speeds, latency (delay), packet loss (data loss), or connection drops. Therefore, satellite internet service users may experience poor or inconsistent internet performance during bad weather

 DROP is the command that is used to completely remove a table and its data from a relational database. DROP is a SQL (Structured Query Language) statement that deletes the definition and contents of a database object, such as a table, index, or view. DROP cannot be undone, so it should be used with caution. For example, the statement DROP TABLE Customers; will delete the table named Customers and all its data from the database. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 144.

To free up space on an HDD without deleting files, using the operating system's compression feature is the best approach. Compression reduces the size of files on the disk by using algorithms to minimize the space they take up, thus freeing up storage capacity while keeping the files accessible.References: File system management, including the use of compression to optimize storage, is a topic discussed in the CompTIA IT Fundamentals, which also covers system utilities and management practices.

A programmer uses DML to modify data in a database. DML stands for Data Manipulation Language, which is a subset of SQL (Structured Query Language) that is used to manipulate or change data in a database. DML includes commands or statements such as INSERT, UPDATE, DELETE, or MERGE, which can be used to add, modify, remove, or combine data in a table or structure within a database. DML can help a programmer to perform various operations or functions on the data in a database. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 143.

A web-based installation is a type of installation that uses a web browser to access and configure the settings of a device, such as a wireless router. A web-based installation typically requires the user to enter the IP address of the device in the browser’s address bar, and then log in with a default username and password. The user can then modify the settings of the device according to their preferences and needs. A web-based installation is different from other types of installations, such as plug-and-play, driver-based, and server-based, which do not use a web browser to configure the device. References: How to Set Up a Wireless Router: A Step-By-Step Guide, step 3; CompTIA IT Fundamentals (ITF+) Certification Guide, page 98.

Eavesdropping is an electronic attack where digital communications are intercepted by an individual whom they are not intended1. This is a confidentiality concern because it violates the principle of limiting access to information to authorized people only. Confidentiality is a set of rules that limits access to information1. Eavesdropping can compromise the secrecy of the information and expose sensitive data to unauthorized parties. References:

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.

The final step in the standard troubleshooting methodology is to document the findings of the problem and the solution. This step involves recording the details of the problem, the steps taken to resolve it, the outcome of the solution, and any preventive measures implemented to avoid future occurrences. Documenting the findings can help to create a knowledge base for future reference, improve communication among IT professionals, and facilitate continuous improvement56. References := CompTIA IT Fundamentals (ITF+) Study Guide, 2nd Edition, Chapter 7: Explain the Troubleshooting Methodology3; Troubleshooting Methodology | IT Support and Help Desk | CompTIA7

Bash is the most likely scripting language to be used in a Linux command-line environment. Bash stands for Bourne-Again Shell, which is a shell program that allows users to interact with the operating system by typing commands or running scripts. Bash is the default shell for most Linux distributions, and it supports features such as variables, loops, functions, and pipes. JavaScript is a scripting language that is mainly used for web development, especially for creating dynamic and interactive web pages. JavaScript can run in a browser or on a server, but it is not commonly used in a Linux command-line environment. PowerShell is a scripting language that is mainly used for Windows administration, especially for automating tasks and managing systems. PowerShell can run commands or scripts in a console or an integrated development environment (IDE), but it is not compatible with Linux by default. C++ is a programming language that is mainly used for software development, especially for creating applications that run close to the hardware or require high performance. C++ can run on various platforms, including Linux, but it is not a scripting language and it requires compilation before execution. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 8: Software Development Concepts

DVI is the most likely connector that would be used to connect a display to a workstation. DVI stands for Digital Visual Interface, which is a standard that transmits digital video signals between devices. DVI can support high-resolution displays and multiple monitors. DVI connectors have three types: DVI-A (analog), DVI-D (digital), and DVI-I (integrated). DVI connectors have different numbers of pins depending on the type and mode. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 54.
