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

Pseudocode represents logic written in plain, human-readable language that resembles programming structure but isn’t actual code:

“Pseudocode allows programmers to design algorithms using readable statements before translating them into actual code.”

Branch and sequence refer to control flow structures, and object-oriented refers to a programming paradigm.

An open-source license allows users to access, modify, and redistribute the software’s source code. It supports user customization and community contributions.

“Open-source software provides access to the source code, allowing users to inspect, modify, and enhance the software.” — CompTIA ITF+ Licensing and Software Concepts

Correct answer: C

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), one of the five critical steps when configuring a wireless router is to change the administrator username and password:

“The Wi-Fi Alliance lists five critical keys to setting up a secured wireless router:

Change the router’s SSID.

Change the administrator username and password. Make sure that it’s a strong password.

Enable WPA3 or WPA2 Personal.

Choose a strong security passphrase.

Connect clients using the same security mode.”

This ensures unauthorized users cannot log in to the router’s settings.

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

The CompTIA Tech+ Study Guide provides a conversion table for storage units:

“1 bit = 1 bit, a single 0 or 1.

8 bits = 1 byte (one text character).

1,000 bytes = 1 kilobyte (KB).”

Thus, 8 bits equals 1 byte.

Chapter 1: Core Hardware Components — Table 1.2 “Bit and Byte Conversions” (p. 36).

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.

According to the CompTIA Tech+ Study Guide:

“Changing Default Usernames and Passwords — The first thing a potential hacker will try to use is the default username or password for a device. Always change them.”

It also emphasizes:

“Enabling passwords and changing default usernames and passwords are essential password management best practices.”

Therefore, the correct action after server setup is to change the default usernames and passwords to secure the system.

The CompTIA Tech+ Study Guide explains:

“Remote support software allows technicians to connect to a user’s computer from another location, troubleshoot issues, install applications, and perform updates without physically being at the same site.”

Additionally, the review question section confirms:

“You are setting up a technical support help desk for a new app. What type of software should you get to help the technicians fix problems more effectively?

Answer: Remote support.”

Thus, the technician in another state uses remote support software to perform the installation.

In flowcharts, a diamond represents a decision point — a place where the program branches based on a yes/no or true/false condition.

“A diamond shape in a flowchart is used to depict a decision, indicating that the flow can take different paths based on a condition.” — CompTIA ITF+ Programming Concepts

Correct answer: B

Interference or poor signal strength is a common issue in Wi-Fi networks, especially in distant or obstructed locations like basements.

“Physical obstructions and electronic interference can weaken wireless signals, leading to connectivity issues in areas like basements.” — CompTIA ITF+ Networking Fundamentals

Correct answer: A
