A database dump involves exporting the entire database or parts of it into a file, which can be used for backup purposes. This file can later be imported to restore the data. Backup and restore system features are key to maintaining data integrity.

Using point-of-sale (POS) systems allows for direct collection of detailed information on customer purchases, which is integral for analyzing shopping patterns. Customer surveys may provide insights but are less reliable due to their voluntary and often subjective nature. A website's 'About Us' page and generic email feedback are not methods to collect data on customer shopping patterns, as they don't generally contain information specific to purchasing habits.

Dividing a problem into smaller parts to analyze each segment independently is a technique known as 'divide and conquer.' This method helps to isolate and pinpoint the source of the problem within a complex system.

The answer is correct because an 'if-else' statement is indeed a common branching structure used in programming. It allows a program to choose between two pathways: one that is taken if the condition evaluates to true ('if' part), and another if the condition evaluates to false ('else' part). This is a basic concept of control flow in programming languages.

The concept of branching with an 'if' statement allows one or more lines of code to be executed conditionally. This means an 'if' statement can execute a block of code, which contains multiple lines, not just a single line. Therefore, the statement is not limited to only one line of code as suggested by the question.

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.

HTML, or HyperText Markup Language, is the standard markup language used to create web pages. It provides the structure of a webpage and is used alongside CSS and JavaScript, which handle presentation and functionality, respectively. XML and JSON are not primarily used for creating web pages; XML is often used for data storage and transport, and JSON is a data interchange format. SQL is a query language for managing data in relational database management systems and is not utilized for web page creation.

A Petabyte (PB) is a unit of storage that is equivalent to 1,024 terabytes (TB). Understanding these larger storage units is important as technology continues to handle increasingly large data sets.

Activating a failover database server ensures that financial transactions can continue processing with minimal downtime during a primary database server's hardware failure. Failover servers are typically synchronized and ready to take over immediately, which is the most appropriate course of action in this context. While restoring from backups is a valid recovery option, it may not support immediate transaction continuity and could result in data loss for any transactions that occurred after the last backup. Requesting technical assistance and performing diagnostics are both proactive measures for resolving the issue, but they will not ensure the continuation of financial transactions during the interim period.

Visual diagramming software is designed to help users create graphical representations of information. Lucidchart is an example of this type of software because it allows users to create a variety of diagrams, including flowcharts and organizational charts, which can be used for planning and illustrating processes or systems.

Reports serve to present data from a database in a structured and readable format. They are used to summarize and communicate information clearly and efficiently to the users, often in the form of tables, charts, or graphs, which make it easier to interpret and make decisions based on data. While 'Visualizing data' is closely related, it is generally just part of what reports in databases aim to achieve, which is broader and includes summarization and communication. 'Importing data into the database' is incorrect because it refers to the process of adding new data to a database, not summarizing or presenting existing data. ‘Updating records in a database’ is also incorrect as it refers to modifying the data within the database, not generating a summary or presentation of the data.

The correct answer is a cloud hosted application because it is dependent on an internet connection for accessing services and editing documents that are stored on servers located across the internet, which is a prime characteristic of this type of application delivery model. Other options do not necessarily require a continuous internet connection for functionality. A locally installed application is stored and runs on the user's own computer and does not require internet access for its primary function. Local network hosted applications require a connection to a local network, but not always the broader internet. Lastly, single-platform applications refer to the type of operating system they can run on, not their internet connectivity requirements.

The graphic designer should use visual diagramming software, as it is specifically designed for creating complex visuals such as logos and other promotional material. This type of software typically provides tools for vector graphics creation, which are essential for producing high-quality, scalable images required for branding and web use. Other types of software mentioned do not specialize in graphic design and therefore would not be as effective for these tasks.

Since there are 1024 bytes in one kilobyte, to convert bytes to kilobytes, you divide the number of bytes by 1024. Therefore, for an image file size of 4000 bytes, dividing by 1024 gives you approximately 3.90625 kilobytes. However, it's common to round to the nearest whole number in everyday usage, so the closest correct answer is 4 KB, which is a slight overestimation. A choice of exactly 3.90625 KB is not provided, as it is standard practice to round to the nearest kilobyte. An answer of 3 KB would be an underestimation, and 1 KB and 2 KB are significantly lower than the actual size.

The clock speed of a processor is measured in GHz (gigahertz) and represents how many cycles per second the processor can perform. A higher clock speed means the processor can perform more cycles each second, leading to faster processing of tasks. For tasks that involve heavy processing like image editing and 3D rendering, a higher clock speed would generally result in better performance, therefore a 3.2 GHz processor would be preferred over the 2.5 GHz one.
