Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q77-Q82):

NEW QUESTION # 77
There are user complaints about slow render times of a custom data table within a Visualforce page that loads thousands of Account records at once.
What can a developer do to help alleviate such issues?

A. Upload a third-party data table library as a static resource.
B. Use the standard Account List controller and implement pagination.
C. Use JavaScript remoting to query the accounts.
D. Use the transient keyword in the Apex code when querying the Account records.

Answer: B

Explanation:
Implementing pagination using the standard Account List controller in Visualforce is a proven method to improve performance when displaying large sets of data. Pagination allows only a subset of records to be fetched and displayed at a time, thereby reducing the load time of the page.

NEW QUESTION # 78
A company uses Dpportunities to track sales to their customers and their org has millions of Opportunities. They want to begin to track revenue over time through a related Revenue object.
As part of their initial implementation, they want to perform a one-time seeding of their data by automatically creating and populating Revenue records for Opportunities, based on complex logic.
They estimate that roughly 100,000 Opportunities will have Revenue records created and populated.
What is the optimal way to automate this?

A. Use Database. executeBatch () to invoke a Queueable class.
B. Use Database. =executeBatch() to invoke a Database. Batchable class.
C. Use system, acheduladeb() to schedule a patakape.Scheduleable class.
D. Use system, enqueuJob (| to invoke a gueusable class.

Answer: B

Explanation:
For a one-time bulk operation on a large data set, using a Database.Batchable class is the best approach. This allows complex logic to be processed in manageable chunks and efficiently manages system resources.

NEW QUESTION # 79
Universal Containers is implementing a new approval process for expense reimbursements. The process requires complex logic to determine the appropriate approver based on factors such as expense amount, employee role, and project type. The solution should allow for flexibility and future changes in the approval rules.
Which approach would be the most suitable for implementing this logic?

A. Use the Salesforce Approval Process feature and define multiple approval steps with entry criteria and approval assignments.
B. Implement a custom formula field to calculate and determine the appropriate approver based on the given criteria.
C. Create a custom Apex class with a method to determine the appropriate approver based on the given criteria.
D. Develop a custom Lightning component to handle the approval logic and integrate it into the expense reimbursement record page.

Answer: C

Explanation:
Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.

NEW QUESTION # 81
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. Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.
B. Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.
C. Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.
D. Use a list custom setting ta disable the trigger for the user who loads the data.

Answer: B

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.
