FC0-U71 Exam Dumps - CompTIA Tech+ Certification Exam

The least privilege model is a principle of giving users the minimum level of access needed to perform their roles. Removing unnecessary access aligns with this principle.

“Least privilege limits users to only the resources necessary for their duties, reducing the risk of unauthorized access.” — CompTIA ITF+ Security Essentials

Correct answer: A

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the SFP (Small Form-Factor Pluggable) connector is directly associated with fiber-optic networking. The guide lists:

“SFP (small form-factor pluggable) connectors are commonly used in fiber-optic connections to allow hot-swappable transceivers for different types of fiber cables.”

Additionally, the same guide’s chapter on Networking Concepts and Technologies explains:

“Fiber-optic around 2 Gbps – Incredibly fast and more expensive than DSL or cable.”

Therefore, fiber Internet is the only service type that uses SFP connectors for data transmission over optical cables.

Disk management is the OS feature used to create, delete, format, or partition storage devices. It allows users to manage drives and volumes locally.

“Disk management tools are used to manage and configure storage devices, including creating and formatting partitions and volumes.” — CompTIA ITF+ Operating System Features

Correct answer: D

The correct answer is C. Configuring automatic software updates. Automatic updates help keep the operating system and applications patched against known security flaws. This is proactive because it reduces exposure before an attack occurs. Cloud backup helps with data recovery, but it does not directly prevent online threats. Updating subscription software may help in some cases, such as antivirus software, but the broader and stronger proactive security measure is automatic software updates. Installing remote access software can increase risk if it is not properly secured.

Exact Extract/Reference: The Tech+ Study Guide states that device hardening “starts with keeping the software up-to-date” and lists patching software as a security-hardening action. It also warns that some updates address “critical security flaws” and that ignoring them can make a PC vulnerable to Internet-based attacks.

The correct answer is A. A flash drive is a small, portable local storage device, so it is useful when a user needs to copy or back up a local file and carry it to another location, such as home. Option B describes cloud storage. Option C describes network file sharing. Option D describes long-term archiving, which is not the best use case for a flash drive because flash drives are small, easy to misplace, and not ideal as long-term archive media.

Exact Extract/Reference: The CompTIA Tech+ Study Guide defines an external flash drive as “a small, portable SSD that connects through a USB port” and says its “primary benefit is portability.” The guide also lists flash drives as a locally attached backup storage option.

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

“The hexadecimal notational system, or base-16… In hex, the numbers 0 to 9 are used, just like in decimal. However, the letters A to F are used to represent decimal numbers 10 through 15.”

This directly confirms that hexadecimal uses digits 0–9 and letters A–F.

To install and use a printer over a network, the printer must have an assigned IP address so that it can be located and communicated with by other devices on the same network.

“Network printers are assigned IP addresses so computers can locate and send print jobs to them over the network.” — CompTIA ITF+ Networking Guide

Correct answer: B

The CompTIA Tech+ Study Guide explains:

“For a table in a database to be relational, it must have a primary key. In fact, its creation is mandatory when a table is created. A primary key is one or more fields whose data is used to identify a record uniquely.”

It further adds:

“Primary keys for tables are stored in an index, which enforces the uniqueness requirement.”

Hence, the unique identifier for records in a relational database is the primary key.
