FC0-U71 Exam Dumps - CompTIA Tech+ Certification Exam

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

“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 explains that:

“Databases generally lock only on a record level (or individual line of data), so multiple people can actively use the database at one time.”

Therefore, the best reason to convert a large spreadsheet to a database is to allow multiple concurrent users to access and update the data simultaneously without conflicts.

Input devices allow users to interact with the computer by sending data to it. The most common input devices for a desktop PC setup are:

Mouse – allows the user to point, click, and interact with the GUI.

Keyboard – used to enter text and commands.

“Input devices such as the keyboard and mouse are essential for entering data into a computer.” — CompTIA ITF+ Study Guide

Other options explained:

A. Printer – Output device

D. CPU – Core processing unit, not an input device

E. Speaker – Output device

F. SSD – Storage device

Correct answers: B and C

Encryption protects files by converting them into unreadable formats unless the correct decryption key is provided. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

"Encryption is the process of converting data into a secure format that cannot be read without a decryption key. Only users with the proper key can access the original data."

File permissions control user access based on OS-level rules, but encryption specifically ensures that only those with the key can read the file even if they access the file storage.

Hidden folders merely conceal files but don’t protect content. Compression reduces file size but doesn’t protect access.

E-readers (especially those using e-ink displays) are specifically designed for reading in bright environments. E-ink mimics the appearance of ink on paper, offering excellent visibility in sunlight with minimal glare and very low power consumption.

“E-readers use e-ink technology which makes the screen easily readable in bright environments like sunlight. This makes them ideal for reading documentation outdoors.” — CompTIA ITF+ Guide

Laptops, tablets, and smartphones may suffer from glare or screen dimming in direct sunlight.

Correct answer: C

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

An embedded operating system is used in dedicated devices such as smart appliances, printers, or industrial machines. It performs specific functions and interacts with other systems, like sending alerts.

“Embedded operating systems are designed to run on specialized hardware with a fixed function, such as in appliances or vehicles.” — CompTIA ITF+ Official Guide

Correct answer: B

The CompTIA Tech+ Study Guide classifies critical data as essential information that organizations depend on for daily functioning:

“Critical data is information without which an organization cannot function effectively. Examples include customer records, transaction data, and operational databases. The loss or corruption of such data can significantly impact business continuity.”

This type of data differs from “big data,” which refers to massive data sets used for analytics, and from “monetized data,” which refers to data sold or used for financial gain.

Chapter 12: Data Continuity and Computer Support — “Understanding Data Importance and Critical Data” (pp. 619–621).

Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:

“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”

Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.
