Explanation
The OmniScript element that can be used to retrieve data from more than one source is Integration Procedure Action. An Integration Procedure Action can execute an Integration Procedure that can combine multiple DataRaptor actions, such as Extract, Transform, and Load, and also invoke REST or SOAP services. This way, the Integration Procedure Action can retrieve data from different sources, such as Salesforce objects or external systems, and store it in a JSON object for the OmniScript to display

Explanation
The OmniStudio tool that the consultant should recommend to get the discounted rate is Calculation Matrices.
A Calculation Matrix is a tool that can perform complex calculations based on multiple input variables and output values. The consultant can use a Calculation Matrix to define the input variables, such as number of lines and internet coverage, and the output values, such as discounted rate. The Calculation Matrix can then apply rules and formulas to calculate the discounted rate for each combination of input variables

Explanation
To create a new quote estimation process that involves multiple steps and a variable number of rows of data, the consultant should recommend the following OmniScript elements:
Edit Block: This is an element that allows the user to add, edit, or delete multiple rows of data in a table-like format. It can be used to capture the service category, number of hours, and hourly rate for each row.
Formula: This is an element that allows the user to perform calculations on data using mathematical expressions. It can be used to calculate the total for each row by multiplying the number of hours with the hourly rate.
Input Block: This is an element that allows the user to enter data using various input types, such as text, number, date, picklist, etc. It can be used to display the formula result for each row and the final price for the quote.
The elements that are not suitable for this scenario are:
Multi-select: This is an element that allows the user to select multiple options from a list. It is not relevant for this scenario, as the user needs to enter data in each row, not select from predefined options.
Step: This is an element that organizes the OmniScript into one or more pages. It is not relevant for this scenario, as it does not capture or display any data.

Explanation
The tool that the consultant should recommend to meet this requirement is Lightning web components.
Lightning web components are custom HTML elements built using HTML and modern JavaScript. They can be used to create rich and interactive user interfaces that display data from various sources and allow users to take actions. In this case, a Lightning web component can be used to display customer 360° information in a console using FlexCards, OmniScripts, or other components. Omniscript is not a tool, but a type of component that can be used to create guided interactions. Visualforce Page is not suitable for this requirement, as it is a legacy technology that uses server-side rendering and does not support modern web standards. FlexCards are not a tool, but a type of component that can be used to display contextual data on record pages.

Explanation
A Text Block element in OmniScript can perform three functions: display links or images, apply text formatting, and format tables. A Text Block element can use HTML tags to create hyperlinks or embed images in the OmniScript. It can also use CSS properties to style the text, such as font size, color, alignment, etc. Additionally, a Text Block element can use HTML table tags to create and format tables in the OmniScript
