FC0-U71 Exam Dumps - CompTIA Tech+ Certification Exam

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

“A crimper is used to attach modular connectors, such as RJ45 or RJ11, to network or phone cables. The crimper pushes the metal contacts into the wires, securing them in place.”

Punchdown tools, by contrast, are used for patch panels or keystone jacks, not RJ45 ends.

Chapter 2: Peripherals and Connectors — “Networking Tools: Crimpers, Punchdown Tools, Cable Testers” (pp. 106–108).

Task management utilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

Correct answer: B

A password reuse policy prevents users from using the same password across multiple platforms or reusing previously used passwords. This is a best practice to reduce the risk of credential stuffing attacks.

“Password reuse policies help ensure users do not reuse old or existing passwords across multiple platforms, reducing exposure from compromised accounts.” — CompTIA ITF+ Security Objectives

Correct answer: A

The correct answer is B. Firewall. A firewall filters network traffic based on configured rules. To disallow inbound file-sharing connections, the firewall can block the relevant inbound traffic. Anti-malware scans for malicious software, multifactor authentication verifies identity, and certificates help establish trust or encryption, but a firewall is the correct control for blocking inbound network connections.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that firewalls “filter inbound and outbound network traffic based on rules defined by the administrator.” It also explains that host-based firewalls protect one computer and that Windows includes Microsoft Defender Firewall. The guide further explains that firewall ACLs determine which traffic is passed and which traffic is blocked.

The correct answer is D. Variable. In the pseudocode, Q receives input from the user and then prints that input. Since the value of Q can change each time the program loops back to line 10, Q is a variable. It is not a constant because constants do not change. It is not a function because it is not a reusable block of code. It is not an array because it does not represent a list of values.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that a “constant” is a predefined number that does not change, while “a variable” means the value can change. It also states that variables can change throughout a program based on input.
