The Campaign Member option is only available for Update when using Data Import Wizard. This means that you can use Data Import Wizard to update existing campaign members with new or modified information, but you cannot use it to create new campaign members from a spreadsheet. To create new campaign members from a spreadsheet, you need to use other tools such as Data Loader, Import Wizard for Leads and Contacts, or Manage Members button on the campaign page.

REGEX is a function that allows administrators to check whether a text value matches a regular expression pattern. Regular expressions are a way to define complex patterns of characters using symbols and operators. REGEX can be used to enforce consistent formatting for a field value by specifying the required length, characters, and separators.

A dashboard is a visual display of key metrics and trends for records in your org. Dashboards allow users to quickly monitor performance and identify trends or issues at a glance. To make it easier for users to see a dashboard they use frequently, administrators can add it to their home page using Lightning App Builder. This way, users can see their dashboard every time they log in or go to their home tab without having to navigate elsewhere.

Duplicate management is a feature that allows administrators to prevent or allow duplicate records for standard or custom objects. Duplicate management consists of two components: duplicate rules and matching rules.
B) Configure custom duplicate rules.
Duplicate rules are rules that determine what actions to take when users try to save duplicate records. Duplicate rules can block users from saving duplicates, alert users of duplicates and let them save anyway, or report on duplicates without affecting the save operation. Duplicate rules can also specify which fields to use for matching and which security settings to enforce. By configuring custom duplicate rules, the sales team administrator can prevent duplicate records from being created for contacts or other objects. Reference: https://help.salesforce.com/s/articleView?id=sf.data_prevent_duplicates.htm&type=5 C) Create custom matching rules.
Matching rules are rules that determine how duplicate records are identified by comparing fields and applying fuzzy matching algorithms. Matching rules can be standard or custom. Standard matching rules are predefined by Salesforce and apply to common objects such as contacts, accounts, or leads. Custom matching rules are created by administrators and apply to any standard or custom object. By creating custom matching rules, the sales team administrator can define how duplicate records are detected for contacts or other objects.
