FC0-U71 Exam Dumps : CompTIA Tech+ Certification Exam

In CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the section “Reviewing Throughput Speeds” explains:

“The most basic measure of throughput is in bits per second (bps)—that is, how many bits are transmitted across the network media (or wireless connection) any given second. Each of the following designations increases that speed by 1000 times:

■ Kilobits per second (Kbps)

■ Megabits per second (Mbps)

■ Gigabits per second (Gbps)

■ Terabits per second (Tbps)”

This shows that Mbps (megabits per second) is the standard measurement unit for Internet connection speed.

802.11X is a wireless security standard,

MHz measures processor frequency, and

Bytes measure data size, not transfer rate.

Because the pay rate is fixed and does not change for all workers, it is best represented as a constant in code. Constants are variables whose values do not change during execution.

“Constants are used in programming to represent fixed values that do not change during the run of a program.” — CompTIA ITF+ Software Development Guide

Correct answer: 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.
