When the network is unavailable, portable storage like a flash drive (USB storage device) is suitable for transferring large files:

“Flash drives provide portable storage solutions capable of handling large data files.”

NAS (network-attached storage) requires a functioning network. RAM is volatile memory not used for file transfer, and cloud storage requires internet connectivity.

Afirewallcan 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

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

Line 10 starts with “FOR Q=1 TO 100,” which is aloop construct. It defines a loop that will run 100 times, incrementing Q from 1 to 100 and executing the enclosed lines (20 and 30).

“Loops are programming constructs that repeat a set of instructions until a condition is met. A ‘FOR’ loop is a common control structure in procedural programming.” — CompTIA ITF+ Official Objectives

Other options:

Attribute applies to objects, not control flow.

Sequence is the overall flow of code lines.

Branches involve decision-making (e.g., IF/ELSE), not repetition.

Correct answer: D

Aprimary keyis a unique identifier for each record in a database table. It must be unique and not null across all rows. In this table, the fieldIDis the only column that uniquely identifies each row and does not repeat.

“A primary key is a field (or a set of fields) that uniquely identifies a record in a table. It ensures that each record can be uniquely retrieved.” — CompTIA ITF+ Official Study Guide

Analysis of other options:

Month,Day,Year, andNamecan have duplicate values across multiple records and therefore do not serve as unique identifiers.

Correct answer: A

The ID field contains unique values for each record and is typically used as a primary key in a database. A primary key uniquely identifies each row in a table.

Month, Day, Year, and Name may have duplicates and do not guarantee uniqueness.

Account logsprovide details about authentication attempts and can confirm whether a user successfully logged in or was denied access.

“Authentication events are recorded in system and application logs, helping verify login success or failure.” — CompTIA ITF+ Security Concepts

A systems administrator resolves a persistent issue with a laptop. Which of the following steps should the administrator take next?

A. Test the theory.

B. Document the findings.

C. Create an action plan.

D. Implement the action plan.

Answer:B

After resolving the issue, the final step in the CompTIA troubleshooting methodology is todocument the findings. This includes noting what was done, what caused the issue, and how it was resolved, so others can reference it in the future.

“After resolving and verifying the issue, document the findings, actions taken, and outcomes to complete the troubleshooting process.” — CompTIA ITF+ Troubleshooting Steps

Correct answer: B

The CompTIA troubleshooting methodology is clearly outlined:

"Once a theory of probable cause has been established, the next step is to test that theory."

Testing confirms whether the identified potential cause is correct before proceeding with action planning, repairs, or documentation.

“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

The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like anarray—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

Pseudocode represents logic written in plain, human-readable language that resembles programming structure but isn’t actual code:

“Pseudocode allows programmers to design algorithms using readable statements before translating them into actual code.”

Branch and sequence refer to control flow structures, and object-oriented refers to a programming paradigm.

To visually represent steps in a process (such as a flowchart or workflow),diagramming softwareis the most appropriate tool. These applications are designed for creating flowcharts, organizational charts, and other process diagrams.

“Diagramming software is used to create visual representations of workflows, processes, and systems. Common uses include flowcharts and process maps.” — CompTIA ITF+ Study Guide

Correct answer: D

The units from smallest to largest are:

MB (Megabyte)

GB (Gigabyte)

TB (Terabyte)

PB (Petabyte)

Thus,PB (Petabyte)is the largest unit listed.

“Data storage is measured in bytes, with increasing units from kilobytes (KB) to megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB).” — CompTIA ITF+ Study Guide

Correct answer: C

The largest unit is determined by converting all values to the same unit:

2TB = 2,000GB

100GB = 100GB

4,000MB = 4GB

50KB = 0.00005GB

Thus, 2TB is the largest. As described in the CompTIA ITF+ FC0-U71 Study Guide:

“Data storage capacity is measured using standard units such as KB, MB, GB, and TB, where 1TB = 1,000GB.”

Aflat fileis a simple database format often stored as a plain text or CSV file. It is ideal for small data sets where speed and simplicity are required.

“Flat files are simple and fast for storing small amounts of data and are easy to process without requiring a full database management system.” — CompTIA ITF+ Data Concepts

Correct answer: A

Process managementin an operating system is responsible for controlling the execution of applications, assigning CPU time, and prioritizing active processes to optimize performance.

CPU speed is measured inmegahertz (MHz)orgigahertz (GHz), indicating how many million or billion cycles the processor can execute per second.

“CPU performance is commonly measured in megahertz (MHz) or gigahertz (GHz), representing the processor’s clock speed.” — CompTIA ITF+

MB is for memory/storage size.

Mbps is for network speed.

MAC is a hardware address, not a performance metric.

Correct answer: A

A simple static web page is best created using amarkup language, such as HTML. Markup languages describe the structure and formatting of content on a web page.

“Markup languages like HTML are used to design and structure static web content. They do not contain logic or interactivity like scripting languages.” — CompTIA ITF+ Study Guide

Correct answer: D

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.

AVPN (Virtual Private Network)creates a secure, encrypted connection over the internet between the user and a remote network, enabling secure access from home or public networks.

“VPNs provide a secure tunnel for transmitting data over unsecured networks, such as the internet, by encrypting all traffic between the client and the network.” — CompTIA ITF+ Security Topics

Other options:

A. LAN – Local and not for remote use

B. FTP – Transfers files but lacks modern encryption

C. DNS – Resolves domain names, not for access

Correct answer: B

This scenario describes a situation where a user has already successfully logged into the system (i.e., has been authenticated) but cannot access a particular network resource (the shared folder). This falls under the concept ofauthorization, which determines what actions or resources a user is permitted to access after authentication.

“Authorization is the process of granting or denying access to network resources once the user has been authenticated.” — CompTIA ITF+ Official Study Guide

Authenticationverifies the identity of the user (e.g., username and password).

Authorizationcontrols access rights (e.g., shared folders, files).

Accountingtracks user activity (e.g., audit logs).

Non-repudiationensures actions or transactions cannot be denied later.

Therefore, the correct answer is B: Authorization.

Achar (character)represents a single letter, number, or symbol. It differs from a string, which is a sequence of characters.

“The char data type stores a single alphanumeric character or symbol.” — CompTIA ITF+ Programming Fundamentals

Correct answer: C

Apassword reusepolicy 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

Output devices display or present data to users:

“A Smart TV displays visual and audio output, qualifying it as an output device.”

Web cameras, keyboards, and microphones are input devices that capture data rather than display or present it.

E-readers(especially those using e-ink displays) are specifically designed for reading in bright environments. E-ink mimics the appearance of ink on paper, offering excellent visibility in sunlight with minimal glare and very low power consumption.

“E-readers use e-ink technology which makes the screen easily readable in bright environments like sunlight. This makes them ideal for reading documentation outdoors.” — CompTIA ITF+ Guide

Laptops, tablets, and smartphones may suffer from glare or screen dimming in direct sunlight.

Correct answer: C

Anaccess pointis a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helpsextend the rangeof 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:

Amodemconnects to the internet via an ISP.

Aserverprovides network services, not range.

Ahost firewallprotects a single device or network; it does not expand connectivity.

Thus, the most appropriate answer is D.
