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

This scenario describes a policy where the system enforces password expiration, prompting users to update passwords after a defined period.

“Password expiration is a security policy that requires users to reset their passwords periodically—commonly 30, 60, or 90 days—to mitigate the risk of compromised credentials.” — CompTIA ITF+ Objectives

Password privacy refers to keeping the password confidential.

Password history restricts reuse of old passwords.

Password complexity enforces character rules (e.g., uppercase, numbers, symbols).

Correct answer: D

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

The CompTIA Tech+ Study Guide defines:

“Devices that use radio frequency (RF) transmit a very limited range, typically only a few inches or so. This technology is fairly common in mobile payment applications. Because of the short distances involved, a related term you’ll see is near-field communication (NFC).”

NFC allows devices such as smartphones to securely transmit payment data over short distances—precisely the method used in vending machine purchases.

Verified Reference:

Chapter 2: Peripherals and Connectors — “Wireless Connections: NFC” (p. 99).

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

For locations without cable or cellular towers, satellite internet is the most viable solution. Satellite does not require terrestrial infrastructure beyond a dish and has global coverage.

“Satellite is often used in remote or rural locations where wired and cellular connectivity is not available. It uses a dish to communicate with orbiting satellites for internet access.” — CompTIA ITF+ Curriculum

Fiber optic and IDSL require ground cabling.

Cellular requires nearby towers, which the scenario rules out.

Correct answer: D. Satellite

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

USB-C supports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.

“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study Guide

VGA, DVI, and even DisplayPort are primarily unidirectional video outputs.

Only USB-C fully supports modern bidirectional multimedia communication.

Correct answer: D

The correct answer is D. Restoring lost files. The main purpose of backups is to protect data so it can be restored after loss, corruption, deletion, or failure. Copying data to a different server and creating shareable copies can happen in some situations, but they are not the primary benefit. Testing outside production is not a direct benefit of regular file backups.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that if data loss or equipment failure occurs, “restoring access will be the most important task,” and after hardware is working, “you can restore missing data.” The guide also includes a Windows exercise specifically titled “Restoring Files.”

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 order of storage units from smallest to largest is:

Kilobyte (KB)

Megabyte (MB)

Terabyte (TB)

Petabyte (PB)

“A kilobyte is approximately 1,000 bytes. It is smaller than a megabyte (1 million bytes), terabyte (1 trillion bytes), or petabyte (1 quadrillion bytes).” — CompTIA ITF+ Reference

Hence, C. Kilobyte is the smallest unit listed.
