Explanation: For integrating a custom object "Member TierUpdate_c" with a journey in Salesforce Marketing Cloud for real-time tier change notifications, the correct data source option is:
Option D "Salesforce Data" as the Entry Source, with the custom object "Member TierUpdate_c" as the data source. This option allows for real-time triggering of journeys in Marketing Cloud based on updates to Salesforce records, in this case, the "Member TierUpdate_c" object which tracks tier upgrades.

Explanation: To meet the hotel group’s requirements for providing live updates to Loyalty members about their program membership without complex customization, the following three tasks should be implemented:
LoyaltyLedger: This feature allows members to view their points balance and transaction history1. It is a key component of the Loyalty Management product that tracks the accumulation and redemption of loyalty points, which is essential for members to stay informed about their membership status.
Contact Record: Maintaining up-to-date contact records is crucial as it ensures that members can receive notifications and access their membership details1. The contact record in Salesforce is the central repository of member information, which can be used to personalize communication and provide members with relevant updates.
LoyaltyMemberTier: Implementing the LoyaltyMemberTier feature enables members to see their current tier status and understand how they can move to the next tier1. This feature motivates members to engage more with the loyalty program by providing them with clear goals and benefits associated with each tier. These features are part of the Salesforce Loyalty Management application and are designed to enhance customer engagement without requiring extensive customization. They enable the hotel group to provide a seamless experience for members to access their loyalty program details.

Explanation: To configure tiers within the Loyalty Program at Northern Trail Outfitters (NTO) for giving vouchers to members in the Premium Tier, the configuration involves Voucher Management; Benefits Setup (in Program console); Benefit Action to define downstream actions and FLOW - Benefit action for orchestration (C). This comprehensive approach allows for the creation and management of vouchers as benefits associated with the Premium Tier, the setup of these benefits within the Loyalty Program console to specify the conditions and entitlements, and the use of Salesforce Flow for orchestrating the process of issuing vouchers to qualifying members.
This method ensures that vouchers are systematically managed, associated with the correct tier and member eligibility criteria, and efficiently distributed to members through automated processes, enhancing the value and appeal of the Premium Tier. Salesforce documentation on Loyalty Management would detail the steps for setting up and managing tier-based benefits, including the use of Voucher Management and Flow for effective benefit administration and member engagement.
