FC0-U71 Exam Dumps - CompTIA Tech+ Questions and Answers

Recording user actions is an example of accounting, which helps track what users do on a system, especially for auditing purposes.

“Accounting refers to the recording and logging of system activities, including tracking user actions within applications or services.” — CompTIA ITF+

Correct answer: A

Accounting refers to the logging and monitoring of user actions. In this case, tracking login events through log files is an example of accounting in the AAA (Authentication, Authorization, Accounting) model.

“Accounting provides auditing and logging of user actions, such as login times and resource access.” — CompTIA ITF+ Security Essentials

Correct answer: A

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

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

The correct answer is A. Unnecessary. The key phrase is “already handled natively by the OS.” Since the operating system already provides Wi-Fi settings management, the extra software is redundant and not required. It is not necessarily malicious, because the question does not say it is harmful. It is not best described as open-source, because licensing is unrelated to whether the software should be removed. “Unwanted” could describe software the user does not want, but “unnecessary” is more precise because the reason for removal is that the OS already performs the same function.

Exact Extract/Reference: The Tech+ Study Guide lists “Removal of software” and specifically includes “Unwanted,” “Unnecessary,” and “Malicious” software under software/security best practices. The guide also states that removing an application can free disk space and memory, and that Tech+ objective 6.2 expects knowledge of removing unwanted, unnecessary, and malicious software.

Installing software typically requires elevated permissions that standard user accounts do not have. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

“An administrator account provides full system access, including installing or removing software, changing system settings, and managing user accounts.”

The user account does not have these privileges by default.

Least privilege refers to granting only the minimum permissions necessary (which would not typically include software installation for regular users).

Single factor refers to authentication methods, not access levels.

Since the employee is denied installation due to insufficient privileges, administrator access is needed to complete the installation.

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.

Encryption protects data by encoding it, so it can only be accessed or read by someone with the proper key or password. It ensures confidentiality during file transfers over insecure networks like the internet.

“Encryption is used to protect data in transit, ensuring that only authorized parties can read the content during transmission.” — CompTIA ITF+ Security Essentials

Correct answer: C

Encryption protects files by converting them into unreadable formats unless the correct decryption key is provided. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

" Encryption is the process of converting data into a secure format that cannot be read without a decryption key. Only users with the proper key can access the original data. "

File permissions control user access based on OS-level rules, but encryption specifically ensures that only those with the key can read the file even if they access the file storage.

Hidden folders merely conceal files but don’t protect content. Compression reduces file size but doesn’t protect access.

The CompTIA Tech+ Study Guide details this advantage:

“If you need to have multiple concurrent users accessing data, you need a database. Flat files don’t do well when several people try to access them at once. In the vast majority of cases, one user might be able to write to the file, but all users will be limited to a read-only copy.”

It further states:

“Databases generally lock only on a record level… so multiple people can actively use the database at one time.”

Therefore, the primary advantage of databases over flat files is support for multiple concurrent users.
