Explanation: Feed Tracking is the Chatter feature that allows field value changes for certain fields to show up on Chatter. Thanks, Publisher Actions, and Topics are other Chatter features, but they do not relate to field value changes.

Explanation:
The app builder should create a master-detail relationship field on the gift card object to support the requirement. A master-detail relationship field creates a parent-child relationship between two objects, where the master record controls certain behaviors of the detail record. In this case, the Account object would be the master and the gift card object would be the detail. By creating a master-detail relationship field, the app builder can meet these requirements:
Track the total number of gift cards opened and gift cards issued on an Account: This can be done by creating roll-up summary fields on the Account object that count or sum up the values from the gift card records related to each account.
Permanently ensure the gift cards are unable to be moved across any other Account once it is created: This can be done by making the master-detail relationship field required on the gift card object, which means that every gift card record must be associated with an account record and cannot be changed once set. Option B, C, and D are not types of fields that can support this requirement.

Explanation: Updating the existing change set with the new changes and redeploying is the most efficient way to move the updated components to the Developer Pro Sandbox.

Explanation: The feature that the app builder should use to create easy access to the document is a custom detail page link on the Contract object. A custom detail page link is a type of custom button or link that can display a URL or execute JavaScript when clicked. The app builder can create a custom detail page link on the Contract object that displays the pricing guidelines document in a new window or tab. Option A is incorrect because a quick action on the Contracts object is not suitable for this requirement, as quick actions are used to create or update records, log calls, send emails, or launch flows. Option B is incorrect because a quick action on the Account object is not suitable for this requirement, as quick actions are not related to the Contract object. Option C is incorrect because a custom detail page link on the Account object is not suitable for this requirement, as custom detail page links are not related to the Contract object.

Explanation: Creating a unique External ID field on the custom object and using Data Loader to upsert records prevents duplicates and ensures correct record updates by matching the unique ID.

Explanation: Roll-up summary fields can be used to count the number of related open cases for an account, including those from parent accounts if the relationship allows roll-up summaries.

Explanation: The selected objects in the sandbox template. This is correct because a partial sandbox only copies a subset of data from production, and the data to be copied is determined by the sandbox template. If the Shipping object was not selected in the template, then its data would not be copied to the sandbox.

Explanation: Criteria-based sharing rules are the best tool to use for automatically sharing records based on specific criteria, such as the opportunity type being "Service Agreement." This rule can share opportunities with all users in a particular role, such as the Service Manager role, when the criteria are met, thereby adhering to the private sharing model while still providing necessary access.
A: Owner-based sharing rules focus on the record owner's role or group, not the record type.
C: Apex sharing is used for more complex scenarios not easily handled by declarative sharing settings.

Explanation: A Scheduled Triggered flow can be used to increment a custom field on the Case object each time the case is reopened, effectively tracking the number of re-openings.

Explanation:
The app builder should use the CASESAFEID(Id) formula to create this new field. The CASESAFEID function returns the 18-digit case-insensitive version of the record ID, which is unique for each record in Salesforce. The 18-digit record ID is useful for exporting data to external systems that require case-sensitive IDs1. Option A, C, and D are not formulas that can return the 18-digit record ID.

Explanation:
To create a custom object along with multiple fields and relationships efficiently from a single interface, the Schema Builder is the ideal tool:
A. Schema Builder. This graphical tool provides a drag-and-drop interface for creating and modifying objects and fields in Salesforce, allowing for a visual layout of database schema.
Steps to use Schema Builder:
Go to Setup Schema Builder.
Drag the 'Object' element into the schema area to create a new custom object. Define the object's properties (e.g., label, API name).
Drag field elements like Text, Number, or Lookup into the object to create fields. Configure each field's properties according to your requirements.
Connect objects via lookup or master-detail relationships by dragging the relationship fields between them.
Save the layout to create all elements in Salesforce.
For more information, review Salesforce's Schema Builder documentation.

Explanation: The solution that an app builder should use to meet this requirement is creating a custom report type with converted leads as the primary object. A custom report type is a template that defines the objects and fields that are available for a report. The app builder can create a custom report type that has converted leads as the primary object and includes fields from related objects, such as accounts, contacts, and opportunities. This way, sales reps can create reports on converted leads and see their related information. Option A is incorrect because enabling preserve lead status in the lead conversion settings does not affect the reporting on converted leads, but rather allows users to retain the original lead status after conversion. Option B is incorrect because assigning the representative view and edit converted leads permission does not affect the reporting on converted leads, but rather allows users to view and edit converted lead records. Option C is incorrect because ensuring the representative has read access to the original lead records does not affect the reporting on converted leads, but rather allows users to view the original lead records.
