Explanation: The main types of building blocks when working in Flow Builder are:
Elements: These are the components that define the logic and functionality of a flow. Elements include actions, assignments, decisions, loops, screens, subflows, and waits.
Resources: These are the variables, constants, formulas, collections, and record choice sets that store data in a flow. Resources can be used as inputs or outputs for elements.
Connectors: These are the arrows that connect elements and resources in a flow. Connectors determine the sequence and direction of the flow execution.

Explanation: The best way for the administrator to accomplish this task is to add the “Order Routing Rank By Closest Distance” action to the fulfillment flow. This action is a flow core action that ranks the fulfillment locations by their distance from the delivery location, and returns a list of ranked locations. The administrator can use this action to find the optimal fulfillment location for each order based on proximity.

Explanation:

Two reasons for using Flows instead of Apex code are:

Flows can be modified and created without a developer. Flows are declarative tools that allow administrators to build complex business logic using clicks instead of code. Flows do not require any programming skills or knowledge, and they can be easily modified and maintained by administrators.

Flows provide a visual debug process. Flows have a built-in debugger that allows administrators to test and troubleshoot their flows in a graphical interface. The debugger shows the flow execution path, the values of variables and sObject fields, and any errors or warnings that occur in the flow.

Explanation: Two steps that are required to add an item to the Actions & Recommendations panel on the Order Summary record page are:
Drag the Actions & Recommendations component on the page. The Actions & Recommendations component is a standard component that displays actions and recommendations based on business logic for records in Lightning Experience orSalesforce mobile app. The administrator can use the Lightning App Builder to drag and drop the Actions &Recommendations component onto the Order Summary record page layout.
Create a new sub-flow. A sub-flow is a type of flow that can be invoked by another flow as an element. A sub-flow can contain logic and actions that are specific to a certain scenario oruse case, such as order fulfillment or payment processing. The administrator can use Flow Builder to create a new sub-flow that defines the actions and recommendations for Order Summaries, and then add it to the Actions & Recommendations component on the record page.

Explanation:

The object that is created and linked to the Order Summary when a customer cancels an order prior to fulfillment is Cancel Order. A Cancel Order is a record that represents a cancellation request for an order or part of an order. A Cancel Order has a lookup relationship to both Order Summary and Change Order objects, and it contains information such as the cancellation reason, status, date, etc. Verified References:https://help.salesforce.com/s/articleView?id=sf.order_management_cancel_order.htm &type=5
