Universal Connect (UC) offers business internet to its customers.

To meet the requirements of offering regional pricing and ensuring customers can see the correct price before adding the product to the cart (i.e., while browsing the catalog), the solution must rely on Context Rules that evaluate the customer's profile (Region) prior to product configuration.

B. Create a Base Price List and Multiple Child Price Lists associated with Context Rules per region:

In Salesforce Industries (Communications Cloud) CPQ, Price Lists are the primary container for prices. You can create specific price lists for each region (e.g., "New York Price List," "Texas Price List") and use Context Rules to automatically assign the correct price list to the user's session based on their Account or Quote details (Region).

Because the Price List is selected before the product is viewed, the catalog automatically displays the price entries from that specific regional list, satisfying the visibility requirement.

D. Create multiple Price List Entries associated with Context Rules per region:

Alternatively, you can use a single global Price List but create multiple Price List Entries (PLEs) for the same "Business Internet" product (e.g., one entry for $50, another for $60).

You can apply Context Rules directly to these Price List Entries. When the catalog renders, the system evaluates the rules against the customer's context (Region) and filters the entries, showing only the one valid for that region.

This allows for granular control at the product price level without necessarily duplicating entire price lists.

Why A is incorrect: Attribute-based Pricing Matrices are typically used for calculating prices based on product attributes that a user selects during configuration (e.g., Speed, Color). Since the requirement is to see the price before adding to the cart (pre-configuration), and Region is a context of the customer not a feature they configure on the product, Context Rules (B & D) are the correct architectural choice.
