Which of the following is the most important consideration when opening a file on an OS GUI?
A
File extension
B
Default permissions
C
Backup policy
D
Data compression
Correct Answer:
A. File extension
Explanation:
The most important consideration when opening a file on an Operating System Graphical User
Interface (OS GUI) is the file extension. A file extension identifies the type of file and determines
which software application can open it. In the official CompTIA ITF+ Student Guide, it is stated that:
“The last part of the file name represents an extension, which describes what type of file it is and is
used by Windows to associate the file with an application.”
“Files are usually opened by double-clicking them. You may want to open a file in a software product
other than the default, however. When you right-click a file, the shortcut menu displays a list of
suitable choices, or you can choose Open With and browse for a different application. You can also
use the Default Programs applet to configure file associations.”
“Do not change a file's extension if it is shown. If you delete or change the extension, the file will not
be associated with the correct program for opening it.”
This means the OS uses the file extension to decide which application to use to open a file. Changing or
deleting the extension can result in the file not opening properly because it no longer matches the
program expected to open it.

A database has the following schema (as shown in the images above):
Which of the following is the number of records in the schema?
A
3
B
4
C
12
D
21
Correct Answer:
B. 4
Explanation:
In the database schema shown in the images, there are four rows (excluding the header row)
representing data entries for four people (John, Jane, Allison, and Anna).
Each row represents a record in the database table, also known as a tuple. The term record refers to
a complete set of fields (ID, Name, and Age) for one entry. So, counting the four rows:
John
Jane
Allison
Anna
That makes a total of 4 records in the database schema.

FC0-U71: Actual Exam Q&A | CLEARCATNET
The official CompTIA ITF+ Study Guide states:
"A record (or tuple) in a database is a complete set of fields that represents one entity – for example,
a single row in a database table."
Thus, the correct answer is B.
Which of the following devices extends the range of a network?
A
Modem
B
. Server
C
Host firewall
D
Access point
Correct Answer:
D. Access point
Explanation:
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.
A user receives a notification about a new software vulnerability. Which of the following is the best
way to secure the software?
A
Configuring a firewall
B
Applying updates
C
. Enabling authentication
D
Uninstalling the program
Correct Answer:
B. Applying updates
Explanation:
When a new vulnerability is discovered in software, the best way to secure it is by applying updates
(patches) released by the software vendor. According to the CompTIA ITF+ objectives:
“Vendors regularly release software updates and security patches to fix vulnerabilities that could be
exploited by attackers. Installing these patches promptly is crucial for maintaining system security.”
Although configuring a firewall and authentication improves overall security, they do not directly
patch or fix the vulnerability. Uninstalling may be an option only if a patch is unavailable or the
software is no longer needed. Therefore, the best and most proactive response is B: Apply updates.
Which of the following is used to determine whether users accessed inappropriate online content?
A
System logs
B
Cookie data
C
Location tracking
D
. Web browser history
Correct Answer:
D. . Web browser history
Explanation:
The web browser history stores records of websites that a user has visited. This is typically the most
straightforward and accessible method for determining whether users accessed inappropriate or
unauthorized online content. The CompTIA ITF+ documentation explains:
FC0-U71: Actual Exam Q&A | CLEARCATNET
“Web browsers maintain a history of visited URLs, which can be used for monitoring and auditing
user activity, including detecting policy violations regarding internet usage.”
System logs are broader and generally capture system or security events.
Cookies store session and tracking data but don’t always show what content was accessed.
Location tracking helps with geolocation, not content monitoring.
Therefore, the correct choice is D.
A company updates its password policy to require that all passwords be reset every 60 days. Which
of the following best describes this requirement?
A
Password complexity
B
. Password management
C
Password expiration
D
Password privacy
Correct Answer:
C. Password expiration
Explanation:
The requirement to change passwords every 60 days is a policy known as password expiration. It is
part of enforcing secure authentication by limiting the amount of time a password is valid.
“Password expiration is a security measure that requires users to change their passwords after a
specific period, such as every 60 or 90 days, to reduce the risk of compromised credentials being
used over time.” — CompTIA ITF+ Official Guide
Password complexity refers to rules about what characters are required.
Password management refers to overall policies and tools for handling passwords.
Password privacy relates to confidentiality but not periodic resets.
Thus, the correct choice is C.
Which of the following encryption types protects data at rest?
A
. File-level
B
VPN
C
HTTPS
D
. Plaintext
Correct Answer:
A. . File-level
Explanation:
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.
Which of the following is the smallest storage unit?
A
Petabyte
B
Terabyte
C
Kilobyte
D
Megabyte
Correct Answer:
C. Kilobyte
Explanation:
The correct order of storage units from smallest to largest is:
Kilobyte (KB)
Megabyte (MB)
Terabyte (TB)
Petabyte (PB)
“A kilobyte is approximately 1,000 bytes. It is smaller than a megabyte (1 million bytes), terabyte (1
trillion bytes), or petabyte (1 quadrillion bytes).” — CompTIA ITF+ Reference
Hence, C. Kilobyte is the smallest unit listed.
A user lives in a remote area that does not have cabling or towers available. The user wants to
connect to the internet. Which of the following is the best solution?
A
Fiber optic
B
IDSL
C
Cellular
D
Satellite
Correct Answer:
D. Satellite
Explanation:
For locations without cable or cellular towers, satellite internet is the most viable solution. Satellite
does not require terrestrial infrastructure beyond a dish and has global coverage.
“Satellite is often used in remote or rural locations where wired and cellular connectivity is not
available. It uses a dish to communicate with orbiting satellites for internet access.” — CompTIA ITF+
Curriculum
Fiber optic and IDSL require ground cabling.
Cellular requires nearby towers, which the scenario rules out.

Correct answer: D. Satellite
Which of the following display types is bidirectional?
A
DisplayPort
B
VGA
C
DVI
D
USB-C
Correct Answer:
D. USB-C
Explanation:
USB-C supports bidirectional communication, which means it can both send and receive data,
including video, audio, power, and data signals over the same cable. This is unlike traditional video
cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.
“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is
also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study
Guide
VGA, DVI, and even DisplayPort are primarily unidirectional video outputs.
Only USB-C fully supports modern bidirectional multimedia communication.
