CompTIA FC0-U61 - CompTIA IT Fundamentals+ Certification Exam

The device configuration type that most likely occurred when the user inserted a USB flash drive into a computer for the first time and saw a message indicating the device is being set up and ready for use is plug-and-play. Plug-and-play is a feature that allows a device to be automatically recognized and configured by the operating system when it is connected to a computer using an interface such as USB or Bluetooth. Plug-and-play simplifies the installation and use of devices by eliminating the need for manual settings or drivers. Driver installation is not the device configuration type that most likely occurred when the user inserted a USB flash drive into a computer for the first time and saw a message indicating the device is being set up and ready for use, but rather part of plug-and-play process. Driver installation involves loading software that enables communication between device and operating system. Driver installation may happen automatically or manually depending on device compatibility with operating system. IP-based configuration is not device configuration type that most likely occurred when user inserted USB flash drive into computer for first time and saw message indicating device is being set up and ready for use, but rather device configuration type that involves assigning IP address to device to enable network communication. IP-based configuration may happen automatically using DHCP protocol

 Cellular would be the best option for Internet service for a six-month survey site in a remote location among the given options. Cellular Internet service uses cellular networks to provide wireless Internet access to devices that have a cellular modem, such as smartphones, tablets, laptops, etc. Cellular Internet service can cover areas where other types of Internet service are not available or reliable, such as rural or remote locations. Cellular Internet service can offer high-speed broadband connections using technologies such as 3G, 4G, LTE, etc., but it may also have drawbacks such as limited coverage, signal interference, data caps, or high costs. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 168.

 A workstation would be the best device for a game developer to buy if the game engine software requires high-end specifications and upgradability. A workstation is a computing device that is designed for professional or specialized applications that require high performance, reliability, and scalability. A workstation typically has more powerful components than a standard desktop computer, such as faster processors, larger memory, better graphics cards, and more storage options. A workstation can also be customized and upgraded to meet specific needs or preferences. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 26.

The 5GHz frequency band is less prone to interference from other household appliances, such as microwaves, cordless phones, and Bluetooth devices, than the 2.4GHz band. The 5GHz band also offers more non-overlapping channels and higher data rates than the 2.4GHz band. However, the 5GHz band has a shorter range and lower penetration than the 2.4GHz band, so the technician should consider the size and layout of the SOHO network before choosing the frequency band. 802.11b and 802.11g are wireless standards that operate in the 2.4GHz band, while 802.11a, 802.11n, and 802.11ac can operate in both the 2.4GHz and 5GHz bands. References:

The best explanation for password expiration is to invalidate any compromised passwords. Password expiration is a security policy that requires users to change their passwords after a certain period of time, such as every 90 days. This reduces the risk of unauthorized access if an attacker obtains the user’s password through phishing, hacking, or other means. If the user changes their password regularly, the old password becomes useless for the attacker. Password expiration does not necessarily disable unused user IDs, as the user may still be able to log in with their new password. Password expiration does not discourage writing down passwords, as some users may still do so to remember their new passwords. Password expiration does not enforce new password complexity rules, as those rules apply to any password change regardless of expiration. References: CompTIA IT Fundamentals (ITF+) Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals and Security Concepts, page 181

A system usage agreement is a document that defines the rules and expectations for using a company’s IT resources, such as computers, networks, intranets, software, and data. A system usage agreement typically covers topics such as acceptable use, security, privacy, monitoring, ownership, and consequences of violations. A system usage agreement helps to protect the company’s assets, reputation, and legal compliance, as well as the users’ rights and responsibilities. Privacy expectations on a company intranet should be limited to what is stated in the system usage agreement, as the company has the right and the duty to monitor and control the intranet for business purposes. Users should not assume that their activities on the intranet are private or confidential, unless the system usage agreement explicitly guarantees such privacy. The other options, such as precedents, HR policy, and word of mouth, are not reliable or consistent sources of privacy expectations, as they may vary, change, or conflict with the system usage agreement or the law. References: CompTIA IT Fundamentals (ITF+) Certification Guide, page 100; 10 Intranet Best Practices for a Successful Intranet in 2021, point 7.

The outcome of a text message that is encrypted from its original form is best described as a cipher. A cipher is a text message that has been transformed into an unreadable or unintelligible form by using an encryption algorithm and a key. Encryption is the process of converting plain text into cipher text to protect the confidentiality, integrity, and authenticity of the message. A vector is not a term used in encryption, but it may refer to a data structure that can store multiple values of the same data type in an ordered sequence. Plain is not a term used in encryption, but it may refer to the original or unencrypted form of a text message. An algorithm is not the outcome of encryption, but it is the method or procedure that is used to perform encryption or decryption. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 7: Security Concepts1

 Password reuse is the practice of using the same password for multiple accounts or services. Password reuse is a bad security habit that can lead to compromise of multiple accounts if one of them is breached by an attacker. Joe has most likely performed password reuse if he thinks his email and banking accounts are also compromised after his password for a social media site was compromised. Joe should use different passwords for different accounts and change them regularly to prevent password reuse. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 208.

 1.22Gbps would be the fastest transfer rate when transferring a file across the network among the given options. A transfer rate is a measure of how much data can be transmitted or received over a network in a given time. A transfer rate is usually expressed in bits per second (bps) or its multiples, such as Kbps (kilobits per second), Mbps (megabits per second), or Gbps (gigabits per second). A higher transfer rate means faster data transmission or reception. 1.22Gbps is equivalent to 1,220Mbps, which is higher than 110Mbps, 123Mbps, or 1001Kbps. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 164.
