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

Conferencing software (e.g., Zoom, Microsoft Teams, Webex) enables users to conduct meetings online using audio, video, and screen sharing.

“Conferencing software facilitates real-time communication and collaboration over the internet through audio and video.” — CompTIA ITF+ Applications and Software

Correct answer: D

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines phishing as:

“Creating a site or sending an email that masquerades as a legitimate secure site but actually steals your information is called phishing.”

It further explains:

“When people talk about phishing, it’s generally in the context of suspicious email because that’s how the term originated. Hackers sent out messages hoping to get someone to take the bait.”

By deleting a suspicious email without opening or clicking links, the user is practicing anti-phishing awareness — a key cybersecurity best practice.

Verified Reference:

Chapter 11: Security Best Practices — “Recognizing Suspicious Sites, Links, and Ads” and “Phishing” (pp. 587–589).

According to the CompTIA Tech+ Study Guide:

“Changing Default Usernames and Passwords — The first thing a potential hacker will try to use is the default username or password for a device. Always change them.”

It also emphasizes:

“Enabling passwords and changing default usernames and passwords are essential password management best practices.”

Therefore, the correct action after server setup is to change the default usernames and passwords to secure the system.

Chapter 11: Security Best Practices — “Managing Passwords” (pp. 594–595).

The correct answer is B. Document the findings. In the troubleshooting methodology, after the issue has been resolved and functionality has been verified, the final step is to document the findings, lessons learned, actions, and outcomes. Testing the theory, creating an action plan, and implementing the action plan all happen before the problem is resolved.

Exact Extract/Reference: The CompTIA Tech+ Study Guide lists the troubleshooting steps in order: identify the problem, establish a theory, test the theory, establish a plan and implement the solution, verify full system functionality, and finally “Document findings/lessons learned, actions, and outcomes.”

To extract specific information from a database, especially recently updated entries, a query is used. Queries filter and retrieve data based on conditions like dates, fields, or status.

“A query is a request for data or information from a database table or combination of tables.” — CompTIA ITF+ Data Management

Correct answer: B

An access point is a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helps extend the range of a wireless network by creating additional coverage areas. This is directly outlined in CompTIA ITF+ documentation:

“A wireless access point (AP) is a device that allows wireless clients to connect to a wired network. It serves to extend or broaden the wireless coverage.”

In contrast:

A modem connects to the internet via an ISP.

A server provides network services, not range.

A host firewall protects a single device or network; it does not expand connectivity.

Thus, the most appropriate answer is D.

RAM (Random Access Memory) in smartphones and computers is most commonly measured in gigabytes (GB) today. Typical smartphone RAM ranges from 2GB to 16GB depending on performance and price.

“Memory capacity in modern devices like smartphones is measured in gigabytes (GB), reflecting their need to support multitasking and app usage.” — CompTIA ITF+ Official Resources

Other options:

KB and MB were used in earlier computing generations.

TB is used for storage, not RAM.

Correct answer: A

The correct answer is C. Onboard NICs are built into the motherboard. An onboard NIC is integrated into the motherboard, while an expansion card NIC is a separate add-on card installed into an expansion slot. The question asks for the primary difference, not speed or cost. Onboard does not automatically mean faster or more expensive.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that Tech+ objective 2.2 expects knowledge of “wired and wireless cards as well as onboard (integrated into the motherboard) versus expansion cards.” It also explains that “most computers today have the NIC circuitry integrated into their motherboards.”

A touch screen functions as both an input and output device. According to the CompTIA ITF+ FC0-U71 Official Study Guide:

" A touchscreen display is a hybrid device combining input and output. It shows visual output like a standard monitor but also allows the user to interact directly by touching the screen. "

" Input devices allow users to provide data or control signals (e.g., keyboard, mouse, touchscreen). "

" Output devices show results from the computer ' s processing (e.g., monitor, printer, touchscreen). "

Touchscreens display information (output) and receive user input through touch (input). They do not perform storage, networking, processing, or logging.
