Explanation:

Three pages that should be enabled for the Guest user profile for a storefront to have anonymous checkout are:

CCPaymentInfo: This page allows the guest user to enter their payment information, such as credit card number, expiration date, and security code. The page also displays the order summary and total amount.

CheckoutNew: This page allows the guest user to enter their shipping and billing information, such as name, address, phone number, and email. The page also displays the cart items and shipping options.

OrderConfirmation: This page displays the confirmation message and order number after the guest user places their order. The page also provides a link to view the order details or print the invoice.
