Explanation:

Correct Answer:
D. Update the change set and re-deploy ✅

Why this is correct:
Once a change set is deployed, you can go back to the source org (Developer Sandbox), open the same outbound change set, and add/remove/update components.
After saving, you can upload it again to the target org (Developer Pro Sandbox) and then re-deploy.
This is the proper way to move updated components after initial deployment.

Why not the others:

A. Refresh the test sandbox and re-deploy the change set ❌
Refreshing a sandbox wipes it clean and resyncs it with production — you’d lose your testing work.
Not required just to update and redeploy a change set.

B. Clone the change set and re-deploy ❌
Cloning creates a new copy, but that’s unnecessary. You can simply update the existing one.
Cloning is more useful if you want a different version for another environment, not when you’re updating an existing deployment path.

C. Rename the change set, add the changes, and re-deploy ❌
Renaming does nothing functionally.
Deployment depends on the contents of the change set, not its name.

Explanation:

The business requirement is to automatically start an approval process when an Opportunity reaches a certain stage ("Secure Commitment"), eliminating the need for manual submission. This is a classic automation scenario.

Why B is Correct (Process Builder):
Process Builder is a powerful, declarative automation tool that can be triggered when a record is created or edited. A process can be built on the Opportunity object to fire when the Stage is changed to "Secure Commitment." Its immediate action can be to Submit for Approval, launching the predefined approval process. This is a standard, out-of-the-box action in Process Builder.
Why C is Correct (Apex):
Apex code (a trigger) can be written on the Opportunity object. The trigger would detect when the Stage field is updated to "Secure Commitment" and then use the Approval. ProcessSubmitRequest method to programmatically submit the record to its approval process. This is a fully customizable and powerful code-based solution.
Why E is Correct (Flow):
A record-triggered flow is the modern successor to Process Builder for automation. It can be configured to run when an Opportunity is created or updated and its stage equals "Secure Commitment." Within the flow, you can use the Submit for Approval element to achieve the exact same result as Process Builder. Salesforce is increasingly directing users to use Flow for this type of automation.

Why A is Incorrect (Workflow):
Workflow Rules are a legacy automation tool. Their available actions are limited to:
New Task
Email Alert
Field Update
Outbound Message
Workflow Rules cannot submit a record for approval. This critical functionality was added in the more modern tools like Process Builder and Flow.

Why D is Incorrect (Chatter Action):
A Chatter Action is a button or link in the Chatter publisher that lets users perform quick actions, like posting a message or updating a record. It is a manual user interface component, not an automation tool. It does not help automatically trigger an approval process.

Summary:
The three features capable of automatically submitting a record for approval based on a criteria change are the modern automation tools: Process Builder, Apex, and Flow.

Explanation:

To prevent users in the Shipping department from deleting records on the custom object Delivery__c, the app builder should focus on object-level security — specifically the Delete permission.

✅ A. Remove the Delete permission from the Shipper profile
Profiles control baseline access to objects.
Removing the Delete permission from the Delivery__c object in the Shipper profile ensures users cannot delete records, regardless of page layout or sharing settings.

✅ D. Use a permission set to remove the Delete permission
If the Shipper users have broader access via other profiles or need flexible control, you can use a permission set to fine-tune access.
Assign a permission set that excludes Delete access to Delivery__c, overriding broader permissions.
These two options directly control whether a user can delete records — the most reliable and scalable approach.

❌ Why the other options don’t work:
B. Change OWD to Private
Controls record visibility, not delete access. Users with delete permission can still delete records they own or that are shared.
C. Remove delete button from page layout
Cosmetic only — users can still delete records via other interfaces (e.g., list views, reports, API) if they have delete permission.

Explanation:
To ensure sales reps input contacts into Salesforce rather than their personal devices:

C. Enable offline create, edit, and delete in Salesforce for Android and iOS.
This feature allows sales reps to enter contact information directly into the Salesforce Mobile App even when they are offline, which syncs back to Salesforce once connectivity is restored.

Steps to enable offline capabilities:
Navigate to Setup Mobile Administration Salesforce Mobile App Offline Settings.
Configure offline settings to allow for creating, editing, and deleting records.
Ensure that the Contact object is available for offline access.
This functionality encourages reps to use Salesforce directly by mitigating connectivity constraints.

For implementation details, refer to Salesforce Mobile App Offline.

Explanation:

B. Update the account search layouts search results columns displayed. When multiple accounts have similar names, adding additional columns to the search results page can help users differentiate between them. For example, including the Billing City, Phone Number, or Account Number in the search results provides more context and helps the user quickly identify the correct record.
C. Update the account search layouts search filter fields. By adding additional fields to the search filter layout, users can narrow their search results using criteria other than just the company name. This is crucial when the company names are similar. For instance, an app builder could add filters for "Billing City" or "Industry" to help users find the correct account more efficiently.

Incorrect answers
A. Update the account search layout’s view filter settings. This is not a standard configuration option for search layouts. View filters are typically associated with list views, not the search results themselves.
D. Update the account search layouts accounts tab columns displayed. While this does affect the "Recently Viewed" list on the Accounts tab, it does not directly impact the search results page shown after a user performs a search. This is a subtle but important distinction.
