FC0-U71 Exam Dumps - CompTIA Tech+ Certification Exam

The correct answer is B. Database. The key requirement is that multiple users must access and edit records at the same time. A database is designed for multiple concurrent users and can lock individual records instead of locking an entire file. A flat file or spreadsheet does not handle simultaneous editing as effectively. A fileshare only provides a shared storage location; it does not provide database-level record locking, indexing, querying, or multiuser data management.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states, “If you need to have multiple concurrent users accessing data, you need a database.” It also explains that flat files do not work well when several users try to access them at once, while databases generally lock only at the record level so multiple people can actively use the database at one time.

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.

The CompTIA Tech+ Study Guide highlights that:

“If no sound is coming from your speakers, even after confirming they’re powered and connected, check your sound settings. The wrong output device may be selected—especially when multiple audio devices are present.”

This describes a misconfigured output—where the OS is sending audio to the wrong device (e.g., Bluetooth or HDMI).

A cable lock (also called a Kensington lock) physically secures the laptop to a fixed object, making it difficult to steal in public spaces.

“Cable locks are physical security devices used to deter laptop theft by anchoring the device to a desk or other stationary object.” — CompTIA ITF+ Official Guide

A. Firewall is software-based and protects data, not the device.

B. Privacy shields prevent screen visibility, not theft.

C. USB locks prevent port access but not physical theft.

Correct answer: D

Line 10 starts with “FOR Q=1 TO 100,” which is a loop construct. It defines a loop that will run 100 times, incrementing Q from 1 to 100 and executing the enclosed lines (20 and 30).

“Loops are programming constructs that repeat a set of instructions until a condition is met. A ‘FOR’ loop is a common control structure in procedural programming.” — CompTIA ITF+ Official Objectives

Other options:

Attribute applies to objects, not control flow.

Sequence is the overall flow of code lines.

Branches involve decision-making (e.g., IF/ELSE), not repetition.

Correct answer: D

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.

The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like an array—a group of data elements stored together.

“An array is a collection of similar data elements stored in a structured sequence, often referenced or processed in loops.” — CompTIA ITF+ Programming Concepts

Correct answer: B

The correct answer is A. Unnecessary. The key phrase is “already handled natively by the OS.” Since the operating system already provides Wi-Fi settings management, the extra software is redundant and not required. It is not necessarily malicious, because the question does not say it is harmful. It is not best described as open-source, because licensing is unrelated to whether the software should be removed. “Unwanted” could describe software the user does not want, but “unnecessary” is more precise because the reason for removal is that the OS already performs the same function.

Exact Extract/Reference: The Tech+ Study Guide lists “Removal of software” and specifically includes “Unwanted,” “Unnecessary,” and “Malicious” software under software/security best practices. The guide also states that removing an application can free disk space and memory, and that Tech+ objective 6.2 expects knowledge of removing unwanted, unnecessary, and malicious software.
