Pass the CompTIA Tech+ FC0-U71 Questions and answers with Dumpstech

Gaming monitors are often described using refresh rates, which are measured in hertz (Hz), often specified in MHz for related processing frequencies. The CompTIA ITF+ FC0-U71 Official Study Guide states:

" Monitor refresh rate refers to how many times per second the screen updates, usually measured in Hz. "

" MHz (megahertz) is used for various frequencies, including GPU and monitor refresh processing. "

GPU and RAM refer to hardware components, TB measures storage, and MHz relates to the frequency, applicable for monitor performance metrics.

A flat file is a simple database format often stored as a plain text or CSV file. It is ideal for small data sets where speed and simplicity are required.

“Flat files are simple and fast for storing small amounts of data and are easy to process without requiring a full database management system.” — CompTIA ITF+ Data Concepts

Correct answer: A

USB-C supports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.

“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study Guide

VGA, DVI, and even DisplayPort are primarily unidirectional video outputs.

Only USB-C fully supports modern bidirectional multimedia communication.

Correct answer: D

Although a phone number contains only digits, it is best stored as a string because:

It doesn’t require mathematical operations.

It may include formatting symbols like dashes or parentheses.

“Phone numbers are stored as strings because they are identifiers, not values for computation.” — CompTIA ITF+ Data Types

Correct answer: A

Meaningful reporting refers to the process of analyzing and summarizing data into actionable insights to support business decisions.

“Reports generated from data analytics provide meaningful insights to support strategic decision-making by company leadership.” — CompTIA ITF+

Correct answer: A

The correct answer is C. Company files saved on a hard disk. Data storage refers to keeping data so it can be used later. A hard disk drive provides long-term, nonvolatile storage and keeps files even when the computer is powered off. RAM is temporary volatile memory, Task Manager shows running processes and system information, and hardware IDs recorded on boards are not the best example of user data storage.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that storage devices provide “long-term, nonvolatile, or persistent storage options,” meaning they do not lose data when powered off. It also states that HDDs are used for “permanent storage and quick access” and hold user data and files the system needs.

The CompTIA Tech+ Study Guide explains:

“Solid-state drives (SSDs) use flash memory, which is non-magnetic and non-volatile. They have no moving parts, unlike HDDs, which use magnetic platters.”

It further notes:

“Conventional hard drives have spinning platters and read/write heads, whereas SSDs use flash memory. SSDs are faster but generally more expensive than their HDD counterparts.”

Therefore, SSD (solid-state drive) meets all the listed requirements.

A query is a request for information from a database. Structured Query Language (SQL) is commonly used to retrieve specific records or information from a data set.

“A query is used to extract and retrieve specific data from a database based on defined criteria.” — CompTIA ITF+ Data Concepts

Correct answer: D

The correct answer is A. Fiber. The typing error “SPF” should be corrected to “SFP,” which stands for small form-factor pluggable. SFP is used with fiber-optic network connections. Ethernet/RJ45 is associated with twisted-pair copper cables. Lightning is an Apple connector, and Thunderbolt is a high-speed peripheral/display interface, not the best match for an SFP router connection.

Exact Extract/Reference: The CompTIA Tech+ Study Guide identifies the “small form-factor pluggable (SFP) connector” as the fiber connector and states, “remember there is RJ45 for twisted-pair copper cables and SFP for fiber-optic cables.”

The correct answer is D. Restoring lost files. The main purpose of backups is to protect data so it can be restored after loss, corruption, deletion, or failure. Copying data to a different server and creating shareable copies can happen in some situations, but they are not the primary benefit. Testing outside production is not a direct benefit of regular file backups.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that if data loss or equipment failure occurs, “restoring access will be the most important task,” and after hardware is working, “you can restore missing data.” The guide also includes a Windows exercise specifically titled “Restoring Files.”
