The correct answer is A. Record-triggered flow.
The app builder needs automation to run when a child record is deleted and then update a field on the related parent record. Salesforce states that a record-triggered flow can automatically perform actions when a record is created, updated, or deleted, without user interaction.
Autolaunched flow can perform logic, but it does not run automatically on record deletion unless invoked by another automation. Validation rule only prevents invalid data entry. Quick action requires user interaction and is not suitable for automatic updates after deletion.

The correct answer is B. Geolocation.
Salesforce geolocation fields are used to identify locations using latitude and longitude and can support distance calculations.
Because Universal Containers delivers containers to remote construction sites and customers provide crossroads or location markers, the app builder should use a Geolocation field to capture location-based information rather than a number, reference, or external lookup field.
Why others are incorrect:
A . Number stores numeric values only.
C . Reference is not the correct field type for capturing physical location.
D . External Lookup is used to relate Salesforce records to external object records, not to store site location details.

The correct answer is B. The deployed permission set will only contain changes related to the change set.
When permission sets are included in change sets, the deployment carries permission settings related to the components included in the change set. The existing permission set in production is not completely overwritten as a whole object, and field-level security changes can be included when the relevant fields are part of the deployment. Salesforce documents permission sets and profile settings as access settings that can be included with change sets.
A is incorrect because the whole permission set is not simply wiped and replaced.
C is incorrect because field-level security can be deployed when included properly.
D is close in plain language, but the more accurate exam answer is that the deployed permission set contains only changes related to the change set.

The correct answer is D.
Universal Containers wants the Account Region value to appear on related Contact records and stay in sync whenever the Account value changes. A cross-object formula field on Contact is the best declarative solution because it dynamically references the parent Account field. Salesforce Trailhead explains that a cross-object formula can pull information from a parent object through a lookup relationship, such as showing Account information on Contact.
Because Account Region is a picklist, the formula must convert the picklist value to text using the TEXT() function. Trailhead gives the same pattern with Account Industry on Contact: TEXT(Account.Industry).
B is incorrect because ISPICKVAL() checks whether a picklist equals a specific text value and returns true/false; it does not display the picklist value.
A and C are incorrect because creating a copied field and trying to update it through a relationship is unnecessary when a formula field can stay synchronized automatically.

The formula must evaluate true when:
Stage = Negotiation/Review
Close Date < 1 week from today
Salesforce formula functions used:
ISPICKVAL() for picklist equality checks
AND() to combine multiple conditions
CloseDate < TODAY() + 7 to check the Close Date is within one week
Correct formula:
AND(
ISPICKVAL(StageName, "Negotiation/Review"),
CloseDate < TODAY() + 7
)
Options A, C, D use invalid syntax (missing quotation marks, incorrect function structure).
Salesforce Help confirms correct syntax for picklist comparison and date arithmetic in formula fields. (Salesforce Help) This formula evaluates true only when both conditions are simultaneously met.
