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

An e-reader is specifically designed for reading digital books using e-ink displays, which are easy on the eyes and readable in bright sunlight. They are lightweight, power-efficient, and ideal for book reading.

“E-readers use electronic ink displays for reading digital books, providing long battery life and excellent visibility in various lighting conditions.” — CompTIA ITF+

Correct answer: B

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

“Inside the BIOS, you can make system configuration selections such as changing the system time, selecting a preferred boot device, or enabling/disabling features.”

Additionally, it details:

“The CMOS chip must have power constantly or it will lose its information (just like RAM does when your computer is powered off). To prevent CMOS from losing its rather important information, motherboard manufacturers include a small battery called the CMOS battery to power the CMOS memory.”

If the system time resets or becomes incorrect after power off, it indicates a BIOS or CMOS battery issue. Configuring or replacing the BIOS/CMOS settings resolves it.

The CompTIA Tech+ Study Guide states:

“Nearly every program running on a computer is run as a process. This includes system operations, background tasks, and applications… The Task Manager utility helps you see everything that’s running on a computer… If I have an app that’s taking up too much memory, I can click it and then click End Task to shut it down. This is also known as killing the process.”

Thus, process management is the OS function that allows users to stop (terminate) running applications.

A firewall can block traffic between workstations if it's not properly configured. If a user cannot connect from one device to another on the network, it is likely that the firewall settings are preventing this communication.

“Firewalls control the incoming and outgoing network traffic based on predetermined security rules. If improperly configured, they may block legitimate access between devices.” — CompTIA ITF+ Study Guide

Other options:

B. Database – Not related to connectivity

C. Anti-malware – Protects from malicious software, not network configuration

D. Certificate – Used for secure communication, but not basic connectivity

Correct answer: A

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

“Some companies’ IT policies require that you change or reset your password at regular intervals, such as every 90 days. The rationale for having a password expiration policy is that the longer you keep a password, the more likely it is that someone has seen it or written it down.”

The guide further notes:

“Many companies have password policies in place that enforce strict requirements… The policy can also make users reset their password every so often, such as 90 days.”

This describes password expiration, which ensures that passwords are periodically updated to reduce security risks.

Installing software typically requires elevated permissions that standard user accounts do not have. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

“An administrator account provides full system access, including installing or removing software, changing system settings, and managing user accounts.”

The user account does not have these privileges by default.

Least privilege refers to granting only the minimum permissions necessary (which would not typically include software installation for regular users).

Single factor refers to authentication methods, not access levels.

Since the employee is denied installation due to insufficient privileges, administrator access is needed to complete the installation.

Task management tools such as Task Manager in Windows or Activity Monitor in macOS allow users to monitor running applications and processes. They also provide the functionality to force-close (end) applications that are not responding.

“Task Manager provides a way to close applications that are unresponsive and manage running processes.” — CompTIA ITF+ Official Guide

Correct answer: A

A printer is an output device because it receives digital data from a computer and converts it into a printed physical format (such as paper).

“Output devices display or reproduce information from the computer. Examples include monitors, speakers, and printers.” — CompTIA ITF+ Fundamentals

Correct answer: B

The CompTIA Tech+ Study Guide details this advantage:

“If you need to have multiple concurrent users accessing data, you need a database. Flat files don’t do well when several people try to access them at once. In the vast majority of cases, one user might be able to write to the file, but all users will be limited to a read-only copy.”

It further states:

“Databases generally lock only on a record level… so multiple people can actively use the database at one time.”

Therefore, the primary advantage of databases over flat files is support for multiple concurrent users.
