Critical data includes information essential to the operation of a business, such as customer databases, financial records, and proprietary information. This data must be identified and prioritized for effective business continuity planning. Backing up non-critical data, although important, does not have the same level of priority. Temporary files and system logs, while useful for various purposes, are generally not considered critical data and would not typically be the focus of immediate recovery efforts in most business continuity plans.

Local network hosted applications are designed to operate within a corporate or home network. They do rely on network connectivity to access the local server where the application data or services are hosted, but they do not require an active internet connection unless they are specifically designed to include online features. This is important for test-takers to understand as it differentiates local network hosted applications from cloud-hosted applications, which do require internet access.

Document databases are well-suited for storing and retrieving JSON documents because they are designed to handle semi-structured data. They store data in a document format, typically JSON, BSON, or XML, which allows for flexible and dynamic schemas. Key/value databases, on the other hand, are more suited for simple key-value pairs where the value can be a basic data type, string, or binary data.

GB stands for Gigabyte, a unit of measurement used to quantify digital information and represents approximately 1 billion bytes. It's important to differentiate between Gigabytes and other units of measure because they represent vastly different quantities of data. For example, a Megabyte (MB) is equal to approximately 1 million bytes, and a Terabyte (TB) represents approximately 1 trillion bytes. Understanding these differences is essential when working with digital storage.

In computing, the execution of such a function where data is manipulated to produce a result is known as processing. This is one of the basic operations a computer performs after receiving input (the numbers you want to add) before delivering an output (the sum of those numbers).

NTFS (New Technology File System) is the correct choice because it supports large files and incorporates permissions for security. NTFS allows files larger than 4GB, which is a limitation of FAT32, another commonly used file system. NTFS also includes features such as encryption and disk quotas, which are not supported by FAT32 or exFAT.

Multifactor authentication (MFA) establishes a more secure environment by requiring two or more independent credentials for user authentication, making it harder for unauthorized users to gain access. A password alone (single factor) is vulnerable to being guessed or stolen. Similarly, a PIN is a type of knowledge-based single factor which can also be compromised. Though strong, biometrics alone could be subject to potential issues such as false positives or negatives and typically need to be paired with another factor to ensure higher security.

Processor speed is measured in Hertz (Hz), with common units being megahertz (MHz) and gigahertz (GHz). A higher clock speed generally indicates a faster processor, contributing to better performance.

The correct answer is true. It is important to change the default password on a wireless router because manufacturers often use generic passwords that can be easily found online by malicious individuals. By changing the default password to a strong, unique one, you greatly enhance the security of the network. Leaving the password as the default one can make the router a target for unauthorized access and potential attacks.

Alice is using the concept of functions. Functions allow a programmer to create a reusable set of instructions. Instead of writing the same code over and over, a function can be defined once and called multiple times whenever the operation is needed. This enhances code readability and maintainability. The other options provided do not directly refer to grouping code for reusability; 'variables' store data values, 'arrays' hold multiple values in a single variable, and 'objects' encapsulate data and behavior but are not specifically for grouping and reusing a set of instructions.

A Server would most benefit from using a 64-bit CPU over a 32-bit CPU, because:

• Memory Access: A 64-bit CPU can address significantly more memory than a 32-bit CPU (up to 18.4 million TB vs. 4 GB), which is especially beneficial for servers that often need large memory capacity for handling extensive databases, virtualization, and heavy multi-user applications.
• Performance: 64-bit CPUs generally offer improved performance for multi-threaded and complex computations, which are common on servers handling multiple requests and large datasets.

While other devices like Gaming PCs and Laptops also benefit from 64-bit CPUs for better performance and memory management, servers typically experience the most significant advantages due to their high demand for processing power and memory.

In the context of data storage, a Byte typically represents a single character. Since there are 1024 characters and the scenario implies that each character is one Byte, the text file consumes 1024 Bytes. It is important to note that 1 KB (Kilobyte) is often considered equivalent to 1024 Bytes due to the binary nature of computing, though in other contexts it may be rounded to a simple 1000.

The correct answer is 'Floating-point number' because this data type allows for the representation of non-integer numbers that include a decimal point. In our scenario, $19.99 cannot be accurately represented as an integer since it is not a whole number. Using an integer would result in loss of precision, as it would have to be rounded to either $19 or $20.

The other options are incorrect because 'Integer' does not allow for decimal precision, 'Boolean' is used for true/false values, and 'Character' is typically used for single letters or symbols, not numbers with decimals.

The statement is false as constants are values that are defined once and do not change throughout the execution of the program. The identifier for a constant refers to a value that remains the same, which is contrary to variables whose values can be modified. Therefore, the concept of constants is to provide values that do not change, which is essential for maintaining reliability in parts of the program's logic where fixed values are necessary.

The correct answer is '8-pin Ethernet connector.' The RJ-45, an 8-pin Ethernet connector, is most commonly used for networking and is the standard for connecting workstations to a network switch. This allows the workstation to communicate with the network and access shared resources. The other options are not suitable as RJ-11 is typically used for telephone connections, not Ethernet networking; VGA and PS/2 connectors are used for video and older keyboard/mouse devices respectively, and are not used for network connections.
