CompTIA ITF+ Certification - IT Fundamentals - (FC0-U61) Exam Questions

The GPU (Graphics Processing Unit) is the correct answer. It is designed specifically for processing and rendering graphics, making it a crucial component for graphical tasks. The cooling system is responsible for dissipating heat generated by the GPU and other components during intensive graphical tasks, ensuring that the GPU can function efficiently. RAM is a type of volatile memory used by a computer system to temporarily store data that's being processed by the CPU. While it might store graphical data temporarily during processing, it does not perform the actual graphics processing. Instead, that task is primarily performed by the GPU and, to a lesser extent, the CPU. The Hard Disk Drive is the primary storage device in a computer, responsible for storing all data and files persistently, even when the power is turned off. However, it is not directly involved in graphics processing. Graphics processing is handled primarily by the CPU and the GPU, which perform computations and render images to be displayed on the screen. The Power Supply Unit provides the necessary power to all the components of the computer system, including the ones that perform graphics processing. However, the PSU itself doesn't participate in the graphics processing. It only provides the required power for the components to function effectively.

Password managers are tools designed to securely store and manage multiple unique passwords, thus reducing the need for password reuse across sites. Password history refers to a record of past passwords used, not to managing multiple unique passwords. Password complexity refers to the use of different types of characters in a password, not to managing multiple unique passwords. Password expiration refers to regularly changing a password, not to managing multiple unique passwords.

Streaming media devices are precisely made to offer digital entertainment by streaming content. They focus on media access and consumption. IoT devices are designed to interact with and automate physical environments. They aren't dedicated to entertainment streaming. Workstations are high-end computers mainly designed for intense computing tasks not primarily related to streaming digital entertainment. While servers can hold and distribute media, they're not specifically built for the purpose of streaming digital entertainment.

Creating written IT policies and procedures is primarily intended to guide employees in understanding and adhering to secure and responsible practices while using the organization's IT resources and services. Written IT policies and procedures can lead to more efficient use of IT resources, which may indirectly help reduce costs. However, their main goal is to ensure safe and secure usage of IT infrastructure. Monitoring employee performance is not the main goal of IT policies and procedures. They are developed to ensure safe and responsible use of the company's IT resources. While IT policies may include guidelines on appropriate internet usage, this is not the primary purpose of these policies. They aim to cover a broader spectrum of secure computing and networking practices.

If a computer is running slow, but internet speed is unaffected, it could be due to insufficient available RAM or hard disk space. This would specifically impact file saving, software running, and general computer processing. Browser hijackers predominantly affect web browsing performance and may change browser settings without permission. Given that internet browsing is unaffected in this scenario, this is unlikely to be the cause of slow system performance. While OS corruption can slow a computer down, it usually presents more severe symptoms, such as system crashes or failure to boot. The symptoms here align more closely with a lack of resources. Although internet browsing is involved in computer operations, the user reports no issues with browsing speed. Therefore, network connectivity is likely not the issue here.

Databases are designed to handle multiple concurrent users. They have mechanisms in place (like locking and transaction control) to handle simultaneous access and modification of data, ensuring data consistency and integrity. Flat files do not have in-built support for managing multiple concurrent users. They lack the advanced features of databases, such as record locking, which can lead to problems with data consistency and integrity when accessed by multiple users simultaneously. While both databases and flat files can be accessed by multiple users, only databases have mechanisms to handle simultaneous access and modification efficiently and safely. Databases do have robust mechanisms for dealing with multiple concurrent users, ensuring that multiple users can access and modify the data efficiently without compromising data integrity.

FAT32 was designed for single-user systems and thus lacks the ability to set permissions on a per-user basis, a necessary feature for multi-user systems. NTFS supports multi-user systems by incorporating file and folder permission settings that allow control over which users can access or modify files. HFS, used predominantly with macOS, supports multi-user systems with its permissions system that can be set on a per-user and per-group basis. Ext4 is designed with Linux in mind, an operating system often used in multi-user environments. Thus, it supports per-user and per-group permissions.

Plain text refers to unencrypted and readable text, while cipher text refers to text that has been encrypted to make it unreadable without the decryption key. The difference between plain text and cipher text is related to encryption, not compression. Plain text and cipher text can both be compressed or uncompressed, depending on other factors. Both plain text and cipher text can be transmitted over a network or stored locally. The primary difference lies in whether the text is encrypted (cipher text) or not (plain text) Plain text is not encrypted, but rather it is the original readable text. Cipher text is the result of encrypting plain text

A Database Dump involves creating a backup of a database, which includes all data and structure in a form such that it can be used to recreate the original database if needed. It's the hero in your disaster recovery plan! Though SQL scripting carries its own significance in database operations, it doesn't aid in recreating the database after a sudden data loss or system mishap. While managing roles and permissions is vital for database security, it doesn't serve as a safeguard for recovery in the event of data loss or system failure. Despite the usefulness of query builders and reporting tools, they can't restore the full database in case of catastrophic system failure or data breach.

Patching updates involve applying software updates, including security patches and bug fixes, to address known vulnerabilities and software bugs in computer systems. Regularly applying patches helps to close security gaps, improve system stability, and mitigate potential threats. Changing default passwords is a good security practice to prevent unauthorized access to devices or systems. However, it does not specifically address known vulnerabilities and software bugs in computer systems. A host firewall controls network traffic for a specific device, acting as a barrier between the device and the network. While it is an important security measure, it does not directly address known vulnerabilities and software bugs in computer systems. Antivirus and anti-malware software are designed to detect and remove malicious software, protecting against various types of threats. However, they do not specifically address known vulnerabilities and software bugs in computer systems.
