Database scalability refers to the capability of a database system to handle a growing amount of work, or its potential to be enlarged to accommodate that growth. Option B, the ability to increase resources easily as demand grows, is the correct answer because scalability involves expanding the capacity of the database as the data volume or the number of users increases, without compromising performance.
Reference: CompTIA IT Fundamentals and other foundational IT resources discuss scalability in the context of database management and performance optimization.

Explanation
The most likely source that will disclose the data collection practices of an application is the EULA. EULA stands for End User License Agreement, which is a legal contract between the software vendor and the user that defines the terms and conditions for using the software. The EULA often includes information about how the software collects, uses, stores, and shares user data, as well as what rights and responsibilities the user has regarding their data. A README.txt file is a text file that accompanies a software package and provides information about how to install, configure, or use the software. A README.txt file may not disclose the data collection practices of an application, unless it is explicitly stated by the vendor. A user's guide is a document that provides instructions and tips on how to use a software application effectively. A user's guide may not disclose the data collection practices of an application, unless it is explicitly stated by the vendor. A vendor website is a web page that provides information about a software vendor and their products or services. A vendor website may disclose the data collection practices of an application, but it may not be as detailed or accessible as the EULA.

The step that happens before establishing a theory of probable cause in the troubleshooting process is identifying the problem. This involves gathering information from the user, observing the symptoms, and systematically ruling out factors that may not be relevant. This step is crucial as it sets the foundation for developing an accurate theory of what might be causing the issue.
Reference: Identifying the problem is part of the systematic approach to troubleshooting taught in CompTIA IT Fundamentals, which outlines a structured process for resolving IT issues.

A constraint is a rule or a restriction that is applied to a column or a table in a relational database to ensure that only valid values are entered. Constraints help to maintain the integrity, accuracy, and consistency of the data. For example, a constraint can be used to specify that a column must not contain null values, or that a column must contain unique values, or that a column must match a value in another table12.
