Q140. A systems administrator connects a printer to a computer. After the printer is set up, it still does not work. Which of the following is the most likely cause of the issue?

Services

Drivers

Permissions

Extensions

Printer drivers are required for the operating system to communicate with the printer; without the correct driver, the printer will not function properly.

Q141. A database administrator creates an outline for a database structure. Which of the following did the administrator create?

Table

Row

Column

Schema

A schema defines the structure and organization of a database, outlining tables, columns, and relationships.

Q142. When working with storage, 1,000,000MB can also be notated as:

0.01PB.

1TB.

100GB

10,000,000KB.

When working with storage, different units of measurement are used to express the amount of data. The most common units are bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Each unit is equal to 1,000 of the previous unit, except for bytes, which are the smallest unit. Therefore, 1,000,000MB can also be notated as 1,000GB or
1TB. The other options are incorrect because they are either too large or too small to represent
1,000,000MB. For example, 0.01PB is equal to 10,000GB or 10TB, which is much larger than
1,000,000MB. Similarly, 100GB is equal to 100,000MB or 0.1TB, which is much smaller than
1,000,000MB. And 10,000,000KB is equal to 10,000MB or 0.01TB, which is also much smaller than 1,000,000MB.

Q143. A user moves to a new desk that is located next to the kitchen. Now, the user can no longer log in to the wireless network. Which of the following is causing this issue?

Speed considerations,

Older standards

Access control

Interference factors

The proximity to the kitchen likely introduces interference (from appliances like microwaves) that disrupts the wireless signal, preventing the user from logging in.

Q144. Which of the following is commonly used to measure the RAM capacity of a smartphone?

Gigabytes (GB) are the standard unit for measuring RAM capacity in modern smartphones, typically ranging from 2GB to 16GB.

Q145. A user purchases a new router and wants to configure it. Which of the following should the user change first?

IP settings

Channel

Gateway

Default password

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), one of the five critical steps when configuring a wireless router is to change the administrator username and password:
“The Wi-Fi Alliance lists five critical keys to setting up a secured wireless router:
* Change the router’s SSID.
* Change the administrator username and password. Make sure that it’s a strong password.
* Enable WPA3 or WPA2 Personal.
* Choose a strong security passphrase.
* Connect clients using the same security mode.”
This ensures unauthorized users cannot log in to the router’s settings.
Verified Reference:
* Chapter 8: Networking Concepts and Technologies – “Setting Up a Small Wireless Network” (pp.
463-467).

Q146. A user needs to illustrate the network. Which of the following is the best type of software for this task?

Word processing

Spreadsheet

Conferencing

Visual diagramming

Visual diagramming software is designed to create network diagrams, allowing users to represent devices, connections, and topology clearly.

Q147. Which of the following is an example of PII? (Select two).

Full name

Date of birth

Employment status

School attended

Social media username

City of residence

Personally Identifiable Information (PII) refers to data that can be used to identify, contact, or locate a single person, or to identify an individual in context. A full name and date of birth are classic examples of PII because they can directly identify a person. Other options listed may relate to a person’s life but do not specifically and directly identify an individual in most contexts.

Q148. A programmer creates an object to retrieve customer names from a database. Which of the following best describes the object that is retrieving the names?

Variable

Attribute

Method

Looping

In object-oriented programming, methods are functions or procedures associated with an object that perform actions such as retrieving data:
* “Methods are actions that an object can perform. They typically manipulate or retrieve data stored within the object.”
* Variables store data, attributes define properties, and loops control repetition but do not directly handle data retrieval within objects.
Reference: CompTIA ITF+ FC0-U71 Official Study Guide, Chapter 8 – Programming Concepts.

Q149. A user moves to a new desk that is located next to the kitchen. Now, the user can no longer log in to the wireless network. Which of the following is causing this issue?

Speed considerations

Older standards

Access control

Interference factors

Wireless interference is often caused by environmental factors such as proximity to kitchens, which may contain microwaves and other electronic devices operating on the same 2.4 GHz frequency used by many Wi- Fi networks. The CompTIA ITF+ FC0-U71 Official Study Guide explains:
* “Wireless signals are subject to interference from physical objects, walls, appliances, and other electronic devices operating on the same frequency.”
* “Microwave ovens and cordless phones are common sources of interference for Wi-Fi networks.” In this case, the user ‘ s proximity to the kitchen is causing interference, not access control or standards issues.

Q151. A social media company tracks user activity for statistical purposes. Which of the following best describes this practice?

Criticality

Monetization

Authentication

Capture

Data capture involves collecting user activity or information for analysis, tracking, or statistical purposes.

Q152. Which of the following defines a reusable value that can be reassigned?

Method

Variable

Constant

Function

A variable is a named container that can store a value of a certain data type, such as a number, a string, or a Boolean. A variable can be reused throughout a program by referring to its name, and its value can be changed or reassigned as needed. For example, in the following Python code, x is a variable that is assigned the value 10, then reassigned the value 20.

Q153. An employee attempts to install software on a PC. A prompt to enter a username and password appears on-screen. The employee then receives an “access denied” message and cannot install the software. Which of the following types of access would allow the employee to accomplish this task?

Least privilege

Administrator

Single factor

User

Installing software typically requires administrator-level access, which grants permission to make system changes.

Q154. Which of the following is the number of bits in a byte of data?

A byte consists of exactly 8 bits. Bits (binary digits) are the smallest unit of data, and eight of them grouped together form one byte, which is used to represent characters and numbers in digital systems.
“A byte is made up of 8 bits and is the standard unit of data used to represent information such as characters in computing.” – CompTIA ITF+ Fundamentals Correct answer: C

Q155. A programmer creates an object to retrieve customer names from a database. Which of the following best describes the object that is retrieving the names?

Variable

Attribute

Method

Looping

A method is a function or procedure associated with an object that performs an action, such as retrieving customer names from a database.
Other options:
*Variable stores data,
*Attribute describes properties of an object,
*Looping refers to repeating code blocks.

Q156. An e-commerce company needs to implement a non-relational database to store customer orders. Which of the following will most likely be a component of this database?

Key/value pair

Primary key

Foreign key

Schema

A non-relational database often uses a key/value pair structure to store and retrieve data efficiently without a fixed schema, making it ideal for flexible data like customer orders.

Q157. Which of the following encryption types protects data at rest?

File-level

VPN

HTTPS

Plaintext

Data at rest refers to information stored on a device or disk, such as a hard drive. The encryption that protects it is typically file-level encryption (or full-disk encryption).
“File-level encryption applies encryption to individual files or directories on storage media and is used to protect data at rest.” – CompTIA ITF+ Study Guide
* VPN and HTTPS protect data in transit.
* Plaintext means data is unencrypted, and therefore is not protective.
Therefore, A is the correct answer.
