Single-factor authentication is a method of verifying a user’s identity by using only one piece of information, such as a username and password. Biometrics, multifactor authentication, and least privilege are not examples of single-factor authentication. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 304.

Processing speed is measured in hertz (Hz), which is the number of cycles per second that a processor can perform. The higher the hertz, the faster the processing speed. There are different units of hertz, such as megahertz (MHz), which is one million hertz, and gigahertz (GHz), which is one billion hertz. Therefore, 3.4MHz is the slowest processing speed among the given options, as it is equivalent to 3.4 million hertz. 2.6GHz is equivalent to 2.6 billion hertz, which is the fastest processing speed among the given options. 5000Kbps and 4Mbps are not units of processing speed, but units of data transfer rate, which measure how much data can be transmitted over a network in a given time. Kbps stands for kilobits per second, and Mbps stands for megabits per second. One megabit is equal to 1000 kilobits, so 4Mbps is equivalent to 4000Kbps. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 1: IT Fundamentals

1 KB (kilobyte) equals approximately 8,000 bits. This calculation is based on the understanding that 1 byte consists of 8 bits, and a kilobyte is made up of about 1,000 bytes. Therefore, multiplying these values together gives us 8,000 bits for 1 kilobyte.

References:The basic units of digital information and their conversions, including bytes and bits, are frequently covered in CompTIA IT Fundamentals study materials, particularly in sections dealing with data storage and digital concepts.

users is a task that is typically performed during the identification phase of the troubleshooting methodology. QUESTION NO: users involves gathering information from the users who are experiencing the problem or who have reported the problem. This can help identify the symptoms, scope, frequency, and impact of the problem. Verify functionality, divide and conquer, and implement the solution are tasks that are typically performed in other phases of the troubleshooting methodology. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 9: Troubleshooting Methodology, page 333.

A concurrent license is a type of software license that allows a software program to be installed on as many computers as the company wants, but only a limited number of users can use the software at the same time. A concurrent license is based on the number of simultaneous users rather than the number of installations. A concurrent license can help a company save money and resources by sharing the software among multiple users who do not need to use the software all the time. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 211.

 A client-server application is an application that runs on a client device and communicates with a server device over a network. The client device requests data or services from the server device, and the server device responds to the requests. A spreadsheet software that connects to a remote database is an example of a client-server application. The spreadsheet software acts as the client, and the database acts as the server. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 128.

 The code uses a for loop to iterate from 1 to 3, and assigns the value of i to the variable x. Then, it adds 3 to x and prints the result. The output of the code is:

3 (when i = 1, x = 1, x + 3 = 4) 6 (when i = 2, x = 2, x + 3 = 5) 9 (when i = 3, x = 3, x + 3 = 6)

NTFS (New Technology File System) is the filesystem most likely to be chosen when encryption support is required on a Windows PC. NTFS supports various features not available in other file systems like FAT32, such as file-level security, data compression, and encryption. It is the default file system for Windows operating systems and is suitable for modern uses that require enhanced security features, including encryption.

References: NTFS and its capabilities, including support for encryption, are standard topics in IT education materials, such as those provided by CompTIA, especially in discussions related to Windows operating systems and their configurations.

 Password reuse is the practice of using the same password for multiple accounts or services. Password reuse is a bad security habit that can lead to compromise of multiple accounts if one of them is breached by an attacker. Joe has most likely performed password reuse if he thinks his email and banking accounts are also compromised after his password for a social media site was compromised. Joe should use different passwords for different accounts and change them regularly to prevent password reuse. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 208.
