The troubleshooting methodology is a systematic approach to solving problems that involves several steps, such as identifying the problem, establishing a theory of probable cause, testing the theory, establishing a plan of action, implementing the solution, verifying functionality, and documenting the findings. One of the steps in identifying the problem is to duplicate the problem, which means to reproduce the same error or issue that the user is experiencing. This can help the technician to verify the symptoms, narrow down the scope, and eliminate possible causes1011. References := CompTIA IT Fundamentals (ITF+) Study Guide, 2nd Edition, Chapter 7: Explain the Troubleshooting Methodology4; Troubleshooting Methodology | IT Support and Help Desk | CompTIA12

 A file extension is a suffix that indicates the type, format, or content of a file. Different file extensions are associated with different applications, programs, or functions. For example, .bat is a file extension for a batch file, which is a script that contains a series of commands to be executed by the command-line interpreter. .avi is a file extension for an audio video interleave file, which is a multimedia container format that stores video and audio data. .rtf is a file extension for a rich text format file, which is a document format that supports text formatting, such as fonts, colors, and styles.

A consolidated group of files is a collection of files that are compressed or archived into a single file, usually to reduce the file size, save disk space, or facilitate file transfer. A consolidated group of files can be created or extracted by using a compression or archiving software, such as WinRAR, 7-Zip, or WinZip. One of the most common file extensions for a consolidated group of files is .rar, which stands for Roshal Archive. .rar is a proprietary file format that supports data compression, error recovery, encryption, and splitting. For example, in the following image1, a folder named Documents contains four files: resume.docx, report.pdf, budget.xlsx, and presentation.pptx. The folder is compressed into a single file named Documents.rar, which has a smaller file size and can be easily attached to an email or uploaded to a cloud storage.

Therefore, the correct answer is C. .rar, as it is the file extension that is used for a consolidated group of files.

Processor speed is measured in hertz (Hz), which is the number of cycles per second that the processor can perform. The higher the processor speed, the faster the processor can execute instructions. Gigahertz (GHz) is equal to one billion hertz, while megahertz (MHz) is equal to one million hertz. Megabits per second (Mbps) and gigabits per second (Gbps) are units of data transfer rate, not processor speed. Therefore, 3.6GHz would indicate the fastest processor speed among the options given. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 3: Computing Components, page 114.

A logo is a graphical representation of a company’s name, brand, or identity. A logo can be protected by both copyright and trademark laws. Copyright is a type of intellectual property that protects the original expression of ideas in tangible forms, such as books, music, art, or software. Copyright protects the logo from being copied, reproduced, or distributed without the permission of the owner. Trademark is a type of intellectual property that protects a word, phrase, symbol, or design that identifies and distinguishes the source of goods or services of one party from those of others. Trademark protects the logo from being used by other parties in a way that causes confusion or deception among consumers. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 211.

 Email software would be used to send messages using the SMTP protocol. SMTP stands for Simple Mail Transfer Protocol, which is a network protocol that enables the transmission of email messages from a client to a server or from one server to another. Email software is an application that allows users to compose, send, receive, and manage email messages using SMTP or other protocols, such as POP3 or IMAP. Examples of email software include Microsoft Outlook, Gmail, Yahoo Mail, etc. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 166.

A variable is the best option to store a test score entered using a web form. In programming, variables are used to store data values that can change over time, such as user input. The variable can be set to store the score when the user submits it, allowing the program to manipulate or display the score later as needed.References: The use of variables for data storage and manipulation is a basic programming concept covered in CompTIA IT Fundamentals and other introductory programming courses.

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
