A company notifies its employees that emails will be automatically moved to a cloud-based server in 180 days. Which of the following describes this concept?
Correct Answer:C
You would like to measure how well an organization is achieving its goals. What type of analysis should you perform?
Correct Answer:A
Performance analysis is the technique of studying or comparing the performance of a specific situation in contrast to the aim and yet executed. In Human Resources, performance analysis can help to review an employee's contribution towards a project or assignment, which they allotted him or her.
Which of the following technologies would be best suited for creating a multiple linear regression model?
Correct Answer:B
R is a statistical programming language that is specifically designed for data analysis and statistical modeling, making it highly suitable for creating a multiple linear regression model. It has extensive libraries such as lm() for linear modeling, which simplifies the process of model creation, diagnostics, and interpretation. R also provides robust tools for data manipulation and visualization, which are essential for preparing data for regression analysis and understanding the results123.
While Microsoft Power BI, SQL, and Tableau have capabilities for regression analysis, they are more limited compared to R. Power BI and Tableau are primarily business intelligence tools that offer some built-in analytics capabilities, but they are not as comprehensive as
R. SQL is a database query language that can perform some statistical calculations, but it is not inherently designed for statistical modeling4567.

You are working with a dataset and want to change the names of categories that you used for different types of books.
What term best describes this action?
Correct Answer:A
The term that best describes the action of changing the names of categories that you used for different types of books is recoding. Recoding is a process of transforming or modifying the values of a variable or a category to make them more meaningful, consistent, or accurate. For example, you can recode the names of book genres from ??Fiction??, ??Non-Fiction??, ??Biography??, etc. to ??FIC??, ??NF??, ??BIO??, etc. to make them shorter and easier to use.

A JSON file is an example of:
Correct Answer:A
A JSON (JavaScript Object Notation) file is a text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa). JSON files are human-readable and can be interpreted by various programming languages, making them ideal for data interchange123.
JSON files typically contain an array of objects, with each object representing a record with a series of name-value pairs. This structured format is both easy to understand and write by humans and easy for machines to parse and generate4.
