Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q139-Q144):

NEW QUESTION # 139
A developer is asked to look into an issue where a scheduled Apex is running into DML limits. Upon investigation, the developer finds that the number of records processed by the scheduled Apex has recently increased to more than 10,000.
What should the developer do to eliminate the limit exception error?

A. Use platform events.
B. Implement the Qususabls interface.
C. Implement the Batchable interface.
D. Use the @future annotation.

Answer: C

Explanation:
When scheduled Apex runs into DML limits due to a high number of records, implementing the Batchable interface is recommended. This allows the job to be broken down into smaller batches that are processed separately, thus avoiding hitting governor limits. Reference:
Using Batch Apex

NEW QUESTION # 140
A developer created an Opportunity trigger that updates the account rating when an associated opportunity is considered high value. Current criteria for an opportunity to be considered high value is an amount greater than or equal to $1,000,000. However, this criteria value can change over time.
There is a new requirement to also display high value opportunities in a Lightning web component.
Which two actions should the developer take to meet these business requirements, and also prevent the business logic that obtains the high value opportunities from being repeated in more than one place?
Choose 2 answers

A. Leave the business logic code inside the trigger for efficiency.
B. Use custom metadata to hold the high value amount.
C. Create a helper class that fetches the high value opportunities,
D. Call the trigger from the Lightning web component.

Answer: B,C

Explanation:
Creating a helper class allows the logic to be centralized and reused in both the trigger and the Lightning Web Component (LWC), avoiding repetition. Using custom metadata to store the criteria value allows easy updates without code changes and can be referenced from both the helper class and the trigger.

NEW QUESTION # 141
An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed and Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records are loaded, the Apex trigger creates Contract records.
A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.
'What is the most extendable way to update the Apex trigger to accomplish this?

A. Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.
B. Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.
C. Use a list custom setting ta disable the trigger for the user who loads the data.
D. Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.

Answer: A

Explanation:
A hierarchy custom setting can be used to create a configuration that the trigger checks before executing its logic. This allows admins to set the configuration to bypass the trigger logic when loading data, without changing the trigger itself or impacting other users.

NEW QUESTION # 142
An org records customer order information in a custom object, ordar__c, that has fields for the shipping address. A developer is tasked with adding code to calculate shipping charges on an order, based on a flat percentage rate associated with the region of the shipping address.
What should the developer use to store the rates by region, so that when the changes are deployed to production no additional steps are needed for the calculation to work?

A. Custom list setting
B. Custom object
C. Custom hierarchy setting
D. Custom metadata type

Answer: D

Explanation:
Custom metadata types are ideal for storing configuration data such as shipping rates by region. These rates can be deployed to production without additional steps and can be queried in Apex, allowing the calculations to work immediately post-deployment.

NEW QUESTION # 143
A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for certain geographic regions.
When a contact is inserted, the default information should be set on the contact from the custom metadata records based on the contact's address information.
Additionally, if a user attempts to delete a contact that belongs to a flagged region, the user must get an error message.
Depending on company personnel resources, what are two ways to automate this?
Choose 2 answers

A. Apex invocable method
B. Flow Builder
C. Apex trigger
D. Remote action

Answer: B,C

Explanation:
To automate the process based on the contact's address information and prevent deletion from flagged regions:
Flow Builder: Can be used to set default information on records when they are created.
Apex Trigger: Allows for complex logic to be executed before or after data manipulation operations, including insert and delete. It can be used to enforce rules such as preventing deletion.
Flow Builder: Salesforce Help Article
