RAM (Random Access Memory) is volatile memory, meaning its contents are erased when power is removed. According to the CompTIA ITF+ FC0-U71 Official Study Guide:

“RAM is volatile storage, which means that it requires constant power to maintain the stored information. When power is turned off, all data in RAM is lost.”

BIOS (firmware), NIC (hardware interface), and CPU (hardware processor) remain unaffected by shutdowns regarding stored information.

Aconsoleor command-line interface (CLI) allows users to input text-based commands that the computer can execute.

“The console (or command prompt or terminal) allows direct command input to control an operating system or application without using a graphical interface.” — CompTIA ITF+ Guide

Services are background processes.

Attributes define properties of objects or elements.

Processes are executing programs but are not used for inputting commands.

Correct answer: D

In terms of storage measurement hierarchy:

1TB = 1,000GB

1GB = 1,000MB

1MB = 1,000KB

Therefore:

20TB = 20,000GB

2,000GB = 2,000GB

200MB = 0.2GB

2,000KB = 0.002GB

Thus, 20TB is the largest. The CompTIA ITF+ FC0-U71 Official Study Guide defines storage units in this way under data representation topics.

Although a phone number contains only digits, it is best stored as astringbecause:

It doesn’t require mathematical operations.

It may include formatting symbols like dashes or parentheses.

“Phone numbers are stored as strings because they are identifiers, not values for computation.” — CompTIA ITF+ Data Types

Correct answer: A

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.

Task managementutilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

Correct answer: B

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

Data monetizationrefers to generating revenue from data assets, such as selling access or insights from collected user data to third parties.

“Data monetization involves using data to generate economic value — for example, selling user data to vendors or advertisers.” — CompTIA ITF+ Data Concepts

Correct answer: A

Anopen-sourcelicense allows users to access, modify, and redistribute the software’s source code. It supports user customization and community contributions.

“Open-source software provides access to the source code, allowing users to inspect, modify, and enhance the software.” — CompTIA ITF+ Licensing and Software Concepts

Correct answer: C

Aloopis a programming construct that repeats a set of instructions while a condition is true. This is used to automate repetitive tasks in code.

“Loops are used in programming to execute the same block of code multiple times under specific conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: A
