CompTIA FC0-U71 - CompTIA Tech+ Certification Exam

Satellite internet typically suffers from higher latency due to the long distances signals must travel to orbit and back. Even with high download speeds, the time delay in communication is significant.

“Satellite internet often experiences high latency due to the long signal travel time between Earth and orbiting satellites.” — CompTIA ITF+ Networking Concepts

Correct answer: C

Conferencing software (e.g., Zoom, Microsoft Teams, Webex) enables users to conduct meetings online using audio, video, and screen sharing.

“Conferencing software facilitates real-time communication and collaboration over the internet through audio and video.” — CompTIA ITF+ Applications and Software

Correct answer: D

A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet between the user and a remote network, enabling secure access from home or public networks.

“VPNs provide a secure tunnel for transmitting data over unsecured networks, such as the internet, by encrypting all traffic between the client and the network.” — CompTIA ITF+ Security Topics

Other options:

A. LAN – Local and not for remote use

B. FTP – Transfers files but lacks modern encryption

C. DNS – Resolves domain names, not for access

Correct answer: D

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

“A router is a highly intelligent network connectivity device that can connect multiple network types to each other. Routers use routing tables to store network addresses and route packets based on the best path available.”

It further clarifies:

“Wireless routers are common in homes and offices. Functionally, wireless routers work just like their wired cousins.”

The default gateway in a home network is the router, as it serves as the device that connects the internal local area network (LAN) to the external Internet.

To install and use a printer over a network, the printer must have an assigned IP address so that it can be located and communicated with by other devices on the same network.

“Network printers are assigned IP addresses so computers can locate and send print jobs to them over the network.” — CompTIA ITF+ Networking Guide

Correct answer: B

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), a flowchart is explicitly defined as:

“A flowchart is a visual representation of a program that uses boxes to represent the logic. Flowcharts are critical in the software development process. They should be created before the code is developed, much like blueprints should be drawn before building a house. They help the developers visualize the flow of the program, making it easier to plan out the sections of code needed.”

The guide further elaborates that:

“Flowcharts show the order of operations within a program, including where data input is needed as well as decisions to be made and the logic choices. Different shapes are used to indicate different components. For example, a rectangle is used to indicate a process, whereas a diamond is used to show a decision point.”

This means the graphical depiction of how code executes step by step—including decisions and actions—is known as a flowchart, not pseudocode (which is text-based “fake code” for readability), nor branching or looping (which are logical control structures).

Additionally, in the “Exam Essentials” section of the same guide, it reinforces that:

“Understand what pseudocode and flowcharts are used for. Pseudocode is most often used to annotate the code with comments to make it easier for people to read. Flowcharts help organize the code and plan out a program.”

The CompTIA Tech+ Study Guide explains:

“For a table in a database to be relational, it must have a primary key. In fact, its creation is mandatory when a table is created. A primary key is one or more fields whose data is used to identify a record uniquely.”

It further adds:

“Primary keys for tables are stored in an index, which enforces the uniqueness requirement.”

Hence, the unique identifier for records in a relational database is the primary key.

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.

A byte consists of exactly 8 bits. Bits (binary digits) are the smallest unit of data, and eight of them grouped together form one byte, which is used to represent characters and numbers in digital systems.

“A byte is made up of 8 bits and is the standard unit of data used to represent information such as characters in computing.” — CompTIA ITF+ Fundamentals

Correct answer: C

RAM (Random Access Memory) is volatile memory, meaning its contents are erased when power is removed. According to the CompTIA ITF+ FC0-U71 Official Study Guide:

“RAM is volatile storage, which means that it requires constant power to maintain the stored information. When power is turned off, all data in RAM is lost.”

BIOS (firmware), NIC (hardware interface), and CPU (hardware processor) remain unaffected by shutdowns regarding stored information.
