FC0-U71 Exam Dumps - CompTIA Tech+ Questions and Answers

RAM allows multiple applications to run simultaneously. Insufficient RAM causes performance drops:

“When several applications are open, the system relies heavily on RAM for temporary storage of active processes.”

Storage, motherboard, or NIC do not directly handle temporary application memory while multitasking.

The CompTIA Tech+ Study Guide lists input devices explicitly:

“Input devices include keyboards, mice, scanners, and web cameras—any device that allows the user to enter data into the computer.”

In contrast, printers and speakers are output devices, while a motherboard is an internal component.

The correct answer is B. Firewall. A firewall filters network traffic based on configured rules. To disallow inbound file-sharing connections, the firewall can block the relevant inbound traffic. Anti-malware scans for malicious software, multifactor authentication verifies identity, and certificates help establish trust or encryption, but a firewall is the correct control for blocking inbound network connections.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that firewalls “filter inbound and outbound network traffic based on rules defined by the administrator.” It also explains that host-based firewalls protect one computer and that Windows includes Microsoft Defender Firewall. The guide further explains that firewall ACLs determine which traffic is passed and which traffic is blocked.

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 least privilege model is a principle of giving users the minimum level of access needed to perform their roles. Removing unnecessary access aligns with this principle.

“Least privilege limits users to only the resources necessary for their duties, reducing the risk of unauthorized access.” — CompTIA ITF+ Security Essentials

Correct answer: A

The CompTIA Tech+ Study Guide clearly defines:

“To talk to the hardware, operating systems use specialized programs called device drivers, or drivers for short. A driver tells the OS how to talk to the specific piece of hardware and how to use its features. If there is no driver for that OS, then the hardware will not be compatible with it.”

Hence, drivers are the software components that control and enable communication between the OS and hardware devices.

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.

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025):

“A crimper is used to attach modular connectors, such as RJ45 or RJ11, to network or phone cables. The crimper pushes the metal contacts into the wires, securing them in place.”

Punchdown tools, by contrast, are used for patch panels or keystone jacks, not RJ45 ends.

The most important consideration when opening a file on an Operating System Graphical User Interface (OS GUI) is the file extension. A file extension identifies the type of file and determines which software application can open it. In the official CompTIA ITF+ Student Guide, it is stated that:

“The last part of the file name represents an extension, which describes what type of file it is and is used by Windows to associate the file with an application.”

“Files are usually opened by double-clicking them. You may want to open a file in a software product other than the default, however. When you right-click a file, the shortcut menu displays a list of suitable choices, or you can choose Open With and browse for a different application. You can also use the Default Programs applet to configure file associations.”

“Do not change a file ' s extension if it is shown. If you delete or change the extension, the file will not be associated with the correct program for opening it.”

This means the OS uses the file extension to decide which application to use to open a file. Changing or deleting the extension can result in the file not opening properly because it no longer matches the program expected to open it.

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+
