CompTIA ITF+ Practice Test (FC0-U61)

Plug-and-play installation is correct because it refers to the capability of a computer system to automatically configure a new device. When you connect a plug-and-play compatible device like a mouse to your computer, the system recognizes it without the need for additional driver installations or manual configurations, making the device ready for immediate use.

Loud grinding or scraping sounds are usually mechanical and originate from moving parts. The most common component that produces such a noise is a failing mechanical hard drive whose read/write heads or spindle bearings are damaged. Software problems, corrupt files, outdated drivers, or network misconfigurations do not create physical grinding sounds.

A man-in-the-middle attack involves an attacker secretly intercepting and possibly altering the communication between two parties who believe they are directly communicating with each other. This can lead to data being compromised or altered, directly impacting its integrity. The other options provided are forms of attacks or malicious activities, but they do not specifically match the description of an intermediary intercepting and modifying the communication between two entities.

A single-use software license typically grants the right to install and use the software on only one computer. Sharing the license with coworkers or installing it for use on multiple machines would violate this type of agreement. While some modern subscription-based licenses may permit installation on a secondary device for the same user, the standard single-use model is one license per machine. Making and selling copies of the software is a copyright violation.

Scripting languages are typically interpreted rather than compiled. They do not require a separate build or compilation stage before execution; instead, an interpreter reads the source (or bytecode) at run time. This trait allows rapid development and makes them well-suited for automating tasks. In contrast, compiled languages-like C or Go-must go through an explicit compilation step that produces machine code before they can be executed.

Checking the spam or junk email folder is a common first step in troubleshooting missing email issues because sometimes legitimate emails are incorrectly flagged as spam by the email client's filtering system. Once identified as not spam, future emails from the same sender may correctly arrive in the inbox. Changing the theme of the email client or adding a signature won't affect the reception of emails. While creating a new email address might eventually solve the problem, it is not a practical first step as it can cause disruption and loss of historical emails.

A high-capacity external hard drive connects over USB and provides multi-terabyte storage, letting you move large datasets quickly between systems without relying on Internet speeds. Cloud storage can be slow for very large uploads, USB flash drives usually offer less capacity for the price, and CDs/DVDs hold only a few gigabytes at most and are rarely used for bulk transfers today.

A 'Primary Key' is a unique identifier for each record in a table, ensuring that no two rows have the same value in this column. This uniqueness is crucial for quickly locating individual records and maintaining data integrity. While a 'Foreign Key' is used to link two tables together, and a 'Composite Key' combines multiple columns to create a unique identifier, the primary key's main role is to provide a unique ID for each row in its own table. 'Indexes' are used to improve search performance but are not unique identifiers for records.

The correct answer is to check the computer's IP configuration. This step is vital as it could reveal if the computer has a valid IP address, subnet mask, gateway, and DNS settings necessary for connecting to the internet. An incorrect IP configuration is a common cause of connectivity issues. The other options are less likely to be the immediate next steps given that the physical network connection (network cable) and network adapter functionality have already been verified.

Using a VPN creates a secure and encrypted connection to the corporate network, which is essential when accessing sensitive data from a remote location. This adds a layer of security that protects against eavesdropping and other threats to confidentiality. While changing passwords regularly, avoiding suspicious links, and reporting lost devices are good security practices, they do not directly pertain to securing the data transmission channel during an active connection to a corporate network.

The data type that best describes a sequence of characters, such as 'John Smith', is a String. Strings are used to represent and work with text. A Char represents a single character, while Types Integers and Floats are used to store numerical data, and a Boolean represents true or false values, none of which are suitable for representing a full name.

Data persistence refers to the longevity of data and its ability to remain in the database in an unaltered state over time. This is a key concept in understanding how databases are designed to ensure reliability and stability of the data they contain. Data will not disappear or change on its own, which is important for maintaining data integrity. 'Data volatility' is incorrect because volatility implies that data is likely to change rapidly and unpredictably, which is not desirable in a database context. 'Data transience' suggests that data is temporary, which contradicts the principle of data persistence. 'Data impermanence' indicates that data is not lasting, which is also the opposite of what is desired in databases.

A database UI utility with a user-friendly input form is the best choice for someone with limited technical experience because it provides an intuitive, graphical interface for data entry. It does not require knowledge of any programming or database structuring language and simplifies the process to something similar to filling out a web form.

A VPN (Virtual Private Network) uses encryption to create a secure connection over the internet between a remote user and an organization's network. This helps in ensuring data privacy and security while the data is in transit. HTTPS encrypts individual web sessions but is not used for securing all the data transmitted from a remote user to a company network. A password manager helps in securely storing and managing passwords, but it does not encrypt data in transit. Antivirus software protects devices from malware but does not encrypt network traffic.

Private browsing is a feature available in most web browsers that allows users to browse the internet without recording the history or storing cookies and temporary files that track their activities. When a private browsing session ends, this information is typically discarded. This is the correct answer because it specifically refers to the functionality of not retaining or storing user activity data during a browsing session. Other answers mention features that do not provide this particular functionality.
