Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q65-Q70):

NEW QUESTION # 65
A developer is working on an integration between Salestorce and an external system. The integration requires sending a large amount of data to the external systern, which can cause long response times and timeouts.
To optimize the performance and avoid timeouts, which technique should be used?

A. Implement an asynchronous callout using the Continuation class,
B. Use a chained batch Apex to split the data into smaller batches.
C. Use the @future annotation to make the callout asynchronous.
D. Increase the timeout limit in the callout options,

Answer: A

Explanation:
Implementing an asynchronous callout using the Continuation class is the optimal solution to handle long response times and avoid timeouts in Salesforce. It allows the Apex code to make a long-running request to an external service and free up the thread to serve other requests.

NEW QUESTION # 66
A company needs to automatically delete sensitive information after seven years.
This could delete almost a million records every day.
How can this be achieved?

A. Use aggregate functions to query for records older than seven years, and then delete the aggrigateResults objects.{civ [+] Schedule a batch Apex process to run every day that queries and deletes records older than seven years.
B. Schedule an @fuzure process to query records older than seven years, and then recursively invoke itself in 1,000 record batches to delete them,
C. Perform a SOSL statement to find records older than 7 years, and then delete the entire result set.

Answer: C

Explanation:
Batch Apex is designed to handle large data operations by breaking the transaction into smaller batches. Scheduling a batch process to run daily enables the system to manage the deletion of large numbers of records efficiently, without hitting governor limits. It's the best practice for performing mass deletions on a regular schedule.
Using Batch Apex

NEW QUESTION # 67
A developer is asked to replace the standard Case creation screen with a custom screen that takes users through a wizard before creating the Case. The org only has users running Lightning Experience.
What should the developer override the Case New Action with to satisfy the requirements?

A. Lightning Record Page
B. Lightning Flow
C. Lightning Component
D. Lightning Page

Lightning Flow

NEW QUESTION # 68
A company has an Apex process that makes multiple extensive database operations and web service callouts. The database processes and web services can take a long time to run and must be run sequentially.
How should the developer write this Apex code without running into governor limits and system limitations?

A. Use Queueable Apex to chain the jobs to run sequentially.
B. Use Apex Scheduler to schedule each process.
C. Use multiple 3zutuze methods for each process and callout.
D. Use Limits class to stop entire process once governor limits are reached.

Answer: A

Explanation:
Queueable Apex is suitable for complex processes that require chaining jobs to run sequentially. It can handle long-running processes without hitting governor limits, as each chained job runs in a new transaction with its own set of governor limits.

NEW QUESTION # 69
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. 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 hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.
D. Use a list custom setting ta disable the trigger for the user who loads the data.

Answer: C

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.
