Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q37-Q42):

NEW QUESTION # 37
A business currently has a process to manually upload orders from its external Order Management System (OMS) into Salesforce.
This is a labor intensive process since accounts must be exported out of Salesforce to get the IDs. The upload file must be updated with the correct account IDs to relate the orders to the corresponding accounts.
Which two recommendations should make this process more efficient?
Choose 2 answers

A. Ensure the data in the file is sorted by the order ID.
B. Identify unique fields on Order and Account and set them as External IDs.
C. Use the upsert wizard in the Data Loader to import the data.
D. Use the insert wizard in the Data Loader to import the data.

Answer: B,C

Explanation:
Setting unique fields on related objects as External IDs allows for the creation of relationships during imports without needing Salesforce IDs. The upsert operation in Data Loader can then use these External IDs to relate records, which streamlines the process and avoids the need to export Salesforce IDs manually.

NEW QUESTION # 38
A developer gets an error saying 'Maximum Trigger Depth Exceeded.'
What is a possible reason to get this error message?

A. A flow trigger was included too many times.
B. A trigger is recursively invoked more than 16 times.
C. The SOQL governor limits are being hit.
D. There are numerous DML operations in the trigger logic.

Answer: B

Explanation:
The "Maximum Trigger Depth Exceeded" error message is typically caused by a trigger being recursively invoked too many times. Salesforce has a limit on the depth of trigger recursion to prevent infinite loops, which is 16 times.

NEW QUESTION # 39
Universal Containers allows customers to log into a Salesforce Community and update their orders via a custom Visualforce page. Universal Containers' sales representatives can edit the orders on the same Visualforce page.
What should a developer use in an Apex test class to test that record sharing is enforced on the Visualforce page?

A. use System. profiles=() to test as a sales rep and a community user.
B. use System. profiles() to test as an administrator and a community user.
C. use System. profiles1h=() to test as a sales rep and a community user.
D. use System. runsAs () to test as an administrator and a community user.

Answer: D

Explanation:
The System.runAs() method is used in test classes to enforce record sharing. This method allows you to write test methods that change user contexts to ensure that the proper record sharing is enforced. Reference:

NEW QUESTION # 40
The Account object has a field, Audit_Code_c, that is used to specify what type of auditing the Account needs and a Lookup to User, zudizar_c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code c. Each User in the org has a unique text field, Audit_Code _e, that is used to automatically assign the correct user to the Account's Auditor_c field.

What should be changed to most optimize the code's efficiency? Choose 2 answers

A. Add an initial SOQL query to get all distinct audit codes.
B. Build a Map<Id, List<string>>of Account Id to audit codes.
C. Add a WHERE clause to the SOQL query to filter on audit codes.
D. Build a Map<string, List<Account>> of audit code to accounts.

Answer: C,D

Explanation:
To optimize the code's efficiency when assigning users to the Account's Auditor field based on the audit code, the following changes should be considered:
B . Building a map of audit code to accounts (Map<string, List<Account>>) would allow for efficient grouping of accounts by their audit code. This would make it easier to process accounts with the same audit code in a single operation, reducing the number of SOQL queries and DML operations needed.
D . Adding a WHERE clause to the SOQL query to filter on audit codes would limit the number of records returned by the query. This means the code only processes relevant User records with matching audit codes, thereby reducing the processing time and memory consumption.
Option A is not recommended because querying for all distinct audit codes without any context of the accounts being processed could be inefficient. Option C is less effective because it would involve creating a mapping of Account Ids to audit codes, which doesn't aid in the efficient assignment of auditor to accounts.

NEW QUESTION # 41
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. Increase the timeout limit in the callout options,
D. Use the @future annotation to make the callout asynchronous.

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.
