NEW QUESTION # 202
A developer is creating a Visualforce page that allows users to create multiple Opportunities. The developer is asked to verify the current user's default Opportunity record type, and set certain default values based on the record type before inserting the record. How can the developer find the current user's default record type?

  • A. Use Opportunity.SObjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate trought them until isdefaultRecordTypeMapping() is true.
  • B. Query the Profile where the ID equals userInfo.getProfileID() and then use the profile.Opportunity.getDefaultRecordType() method.
  • C. Use the Schema.userInfo.Opportunity.getDefaultRecordType() method.
  • D. Create the opportunity and check the opportunity.recordType before inserting, which will have the record ID of the current user's default record type

Answer: A


NEW QUESTION # 203
Universal Containers wants Opportunities to no longer be editable when it reaches the Closed/Won stage.
Which two strategies can a developer use to accomplish this?

  • A. Use an auto-response rule.
  • B. Use a before-save Apex trigger.
  • C. Use an automatically launched Approval Process.
  • D. Use a validation rule.

Answer: B,D

Explanation:
Universal Containers wants to prevent Opportunities from being edited once they reach the Closed/Won stage. To achieve this, the developer can use the following strategies:
Option A: Use a validation rule.
Correct Approach.
A validation rule can be created on the Opportunity object to prevent users from editing records when the Stage is Closed/Won.
The validation rule would evaluate whether the record's StageName is 'Closed Won' and, if so, display an error message when a user attempts to edit and save the record.
Example Validation Rule:
AND(
ISPICKVAL(StageName, 'Closed Won'),
ISCHANGED(ANYFIELD) // Replace ANYFIELD with specific fields if needed
)
Benefits:
Declarative Solution: No code required.
Consistent Enforcement: Applies across all user interfaces and API.
An Apex trigger can be written to check if an Opportunity record being modified has a StageName of 'Closed Won'.
In a before update trigger, the trigger can prevent the save operation by adding an error to the record.
Sample Apex Trigger:
trigger PreventOpportunityEdit on Opportunity (before update) {
for (Opportunity opp : Trigger.new) {
Opportunity oldOpp = Trigger.oldMap.get(opp.Id);
if (oldOpp.StageName == 'Closed Won' && opp != oldOpp) {
opp.addError('Closed Won Opportunities cannot be edited.');
}
}
}
Benefits:
Programmatic Control: Allows for complex logic.
Granular Enforcement: Can specify exact conditions under which edits are prevented.
Approval Processes are designed for record approval workflows.
They do not inherently prevent edits based on a field value like StageName.
Option D: Use an auto-response rule.
Incorrect.
Auto-response rules are used to send automated email responses to Leads or Cases.
They do not control record editability.
Conclusion:
The most appropriate strategies are A (Validation Rule) and B (Before-save Apex Trigger).
Both methods effectively prevent users from editing Opportunities in the Closed/Won stage.
Reference:

Validation Rule Examples
Option B: Use a before-save Apex trigger.
Correct Approach.

Options Not Suitable:
Option C: Use an automatically launched Approval Process.
Incorrect.

NEW QUESTION # 205
A primaryid_c custom field exists on the candidate_c custom object. The filed is used to store each candidate's id number and is marked as Unique in the schema definition.
As part of a data enrichment process. Universal Containers has a CSV file that contains updated data for all candidates in the system, the file contains each Candidate's primary id as a data point. Universal Containers wants to upload this information into Salesforce, while ensuring all data rows are correctly mapped to a candidate in the system.
Which technique should the developer implement to streamline the data upload?

  • A. Create a Process Builder on the Candidate_c object to map the records.
  • B. Update the primaryid__c field definition to mark it as an External Id
  • C. Upload the CSV into a custom object related to Candidate_c.
  • D. Create a before Insert trigger to correctly map the records.
