NEW QUESTION # 12
Which of the following is the number of bits in a byte of data?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: C

Explanation:
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

NEW QUESTION # 13
A user's device is experiencing slow processing performance when multiple applications are running at the same time. Which of the following components is causing this issue?

• A. Storage
• B. Motherboard
• C. RAM
• D. NIC

Answer: C

Explanation:
RAM allows multiple applications to run simultaneously. Insufficient RAM causes performance drops:
"When several applications are open, the system relies heavily on RAM for temporary storage of active processes." Storage, motherboard, or NIC do not directly handle temporary application memory while multitasking.

NEW QUESTION # 14
Which of the following can be used to stop an application that is no longer responding?

• A. Access management
• B. Task management
  C Disk management
• C. Device management

Answer: B

Explanation:
Task management (such as using Task Manager in Windows) allows users to view and stop unresponsive applications.
Other options:
*Access management controls user permissions,
*Disk management handles storage devices,
*Device management manages hardware components.

NEW QUESTION # 15
Which of the following makes a file readable only by select users who possess a key?

• A. File permissions
• B. Hidden folders
• C. Compression
• D. Encryption

Answer: D

Explanation:
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.

Other options:
*Printer and speaker are output devices,
*CPU is a processing unit,
*SSD is a storage device.

NEW QUESTION # 18
A user logs in with the same credentials across multiple websites. Which of the following password policies would most likely prevent this practice?

• A. Complexity
• B. Reuse
• C. Length
• D. Privacy

Answer: B

Explanation:
A password reuse policy prevents users from using the same password across multiple systems or websites, helping to improve security by reducing the impact of a compromised password.
Other options:
*Complexity ensures password strength,
*Privacy relates to keeping passwords secret,
*Length specifies the minimum number of characters.

NEW QUESTION # 19
Which of the following devices extends the range of a network?

• A. Modem
• B. Host firewall
• C. Server
• D. Access point

Answer: D

Explanation:
An access point extends the range of a wireless network by allowing more devices to connect and by covering additional physical areas. The other options serve different purposes:
*Modem connects to the internet,
*Server provides services,
*Host firewall protects a device but does not extend network range.

NEW QUESTION # 20
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?

• A. Least privilege
• B. Administrator
• C. User
• D. Single factor

Answer: B

Explanation:
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.
