To track the total number of trails associated with a park without writing code, the correct actions to take are:

Use a roll-up summary field on the Park record to show the total number of Trails (B). Roll-up summary fields calculate and display a value in a master record based on the values of fields in a detail record. They are used to count, sum, average, or get the minimum/maximum of values in related detail records.

Use a master-detail relationship between the Park and Trail objects (C). Master-detail relationships are necessary for roll-up summary fields as they allow the master object to control certain behaviors of the detail object and summarize data from those detail records.

A formula field (A) cannot dynamically count related records unless those records are linked via a master-detail relationship, and it cannot alone handle counts across related records without such a relationship. A lookup relationship (D) does not support roll-up summaries unless combined with additional tools like triggers or third-party apps, which involve coding or extra configuration outside standard object setup.

For more details, refer to the Salesforce Help documentation on master-detail relationships and roll-up summary fields:

The opportunity standard fields that are available to be configured directly are Stage, Lead Source, and Type. These fields can be modified by editing their picklist values, adding or removing values, or changing their default values. Option A is incorrect because Forecast Category is not a standard field on the opportunity object, but rather a system field that is automatically derived from the Stage field.

The correct validation rule formula to ensure that the Scheduled Ship Date field is properly filled out before setting the Opportunity to Closed Won is:

OR(ISPICKVAL( StageName ,“Closed Won”) && ( Scheduled_Ship_Date_cCloseDate)>14,ISBLANK(Scheduled_Ship_Date_c))

This formula checks two conditions: if the StageName is Closed Won and the Scheduled Ship Date is more than 14 days after the Close Date, or if the Scheduled Ship Date is blank. If either condition is true, the validation rule will fire and prevent saving the record. The other formulas are incorrect because they either use incorrect syntax (such as “=” instead of “,” or missing parentheses) or incorrect logic (such as checking if the Scheduled Ship Date is less than 14 days after the Close Date)

 It will fail if there is a feature only available in the next version. According to the Salesforce documentation, “If your sandbox is on a newer version than your production org, you can’t deploy any components that are new in the sandbox version.” The change set components will not be upgraded to the next version in production, the change set will not be automatically deployed when production is upgraded, and the deployment is possible if there are no new features involved.

Approval Process is the feature that would be used to handle the requirement of signing off on major show retail deals with more than 30% discount. According to the Salesforce documentation, “An approval process automates how Salesforce records are approved in your org.” Email Alert, Field Update, and Workflow Rule are actions that can be triggered by an approval process, but they are not features for handling approvals.

The correct method to upgrade an unmanaged package that is installed in a production environment is to use the update link provided on the Installed Packages page. This process ensures that any modifications or additions in the package are properly integrated without the need to uninstall the previous version, thus preserving existing customizations and data.

A: Uninstalling removes all associated data and customizations, which is not advisable.

B: The Install Wizard is used for initial installations, not upgrades.

To manage frequently changing picklist values effectively:

B. Set up Global Values in Picklist Value Sets. This approach allows for centralized management of picklist values that can be reused across multiple fields and objects. By using global value sets, inactive values can be efficiently managed and deactivated without impacting fields that use these sets.

For further information on managing picklists, check Salesforce's Picklist Management guide.

 The two features of Chatter that would meet CK’s business needs are: Set up new public Chatter groups. A public Chatter group is a way to create a collaborative space for users to share information, files, polls, and ideas around a common topic or interest. A public Chatter group can be joined by any user in the organization and can be seen by anyone who has access to Chatter. By setting up new public Chatter groups, CK can enable users to socialize and collaborate around customer accounts and discuss various topics. Use post action on the Account object. A post action is a type of quick action that allows users to create a post on a record’s feed or on their own feed. A post can include text, mentions, hashtags, topics, links, files, or images. By using post action on the Account object, CK can enable users to share updates, feedback, or questions about customer accounts and engage with other users who follow the accounts. Set up new private Chatter groups is not a valid feature, as it does not meet CK’s business needs. A private Chatter group is a way to create a collaborative space for users to share information, files, polls, and ideas around a confidential or sensitive topic or interest. A private Chatter group can only be joined by invitation and can only be seen by the group members. By setting up new private Chatter groups, CK would limit the visibility and accessibility of the conversations around customer accounts. Use Chatter actions to create tasks to complete is not a valid feature, as it does not meet CK’s business needs. A Chatter action is a type of quick action that allows users to create a task from a record’s feed or from their own feed. A task can include subject, due date, priority, status, assigned to, etc. By using Chatter actions to create tasks to complete, CK would enable users to track and manage their work related to customer accounts, but not to socialize and collaborate with other users.

When multiple objects require the same picklist values, the correct approach is to create a Global Picklist Value Set (also called a Global Value Set). This allows an organization to maintain one centralized list of picklist values that can be reused across multiple picklist fields on different objects.

Why C is correct:Exact Extract:“Global value sets let you share the same picklist values with more than one picklist field. A global value set is a set of shared values that you define once and use in multiple custom picklist fields.” — Salesforce Help | Global Value SetsThis ensures consistent data values, simplifies maintenance, and makes changes automatically available wherever the global picklist is used.

Why not A (Related Picklist):“Related Picklist” is not a valid Salesforce feature.

Why not B (Shared Custom Field):Salesforce does not provide a “Shared Custom Field” functionality. Each field belongs to a specific object.

Why not D (Dependent Picklist):Dependent picklists control available values based on another field’s value. They do not allow reuse of a single value list across multiple objects.

The most likely reason why users are unable to view the custom Lightning component on mobile devices is that the component has been developed for Desktop Pages only. Some components are not supported on mobile devices or have different behavior on mobile devices. An app builder should check the component documentation or metadata to see if it is compatible with mobile devices.
