Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q41-Q46):NEW QUESTION # 41
A corporation has many different Salesforce orgs, with some different objects and some common objects, and wants to build a single Java application that can create, retrieve, and update common object records in all of the different orgs.
Which method of integration should the application use?
  • A. Apex REST Web Service
  • B. Metadata APT
  • C. SOAP API with the Enterprise WSDL
  • D. SOAP API with the Partner WSDL
Answer: D
Explanation:
The SOAP API with the Partner WSDL is ideal for building integrations that work across multiple Salesforce orgs, especially when they have varying schemas. The Partner WSDL is designed to be flexible and dynamic, catering to different metadata.

NEW QUESTION # 42
Consider the following code snippet:

As part of the deployment cycle, a developer creates the following test class:

When the test class runs, the assertion fails. Which change should the developer implement in the Apex test method to ensure the test method executes successfully? A)

B)

C)

D)

  • A. Option D
  • B. Option A
  • C. Option C
  • D. Option B
Answer: D
Explanation:
To ensure that test methods execute successfully and are able to verify the behavior of the code, it is important to set up the proper context and to make sure that the test covers the expected outcomes accurately.
Option B is correct because enclosing the method call within Test.startTest() and Test.stopTest() ensures that any asynchronous operations are completed before the assertions are made. This is crucial when the code being tested is expected to perform operations that may run after the initial transaction, such as future methods, queueable jobs, or batch operations.
Options A, C, and D are incorrect because they do not address the issue of ensuring that all operations are completed before the assertion is made. Option A incorrectly suggests modifying the test setup code, while Options C and D suggest changes that are not related to the test execution flow.

NEW QUESTION # 43
A developer wrote a test class that successfully asserts a trigger on Account, It fires and updates data correctly In a sandbox environment.
A Salesforce admin with a custom profile attempts to deploy this trigger via a change set into the production environment, but the test class falls with an Insufficient privileges error.
What should a developer do to fix the problem?
  • A. Add seeallData=true to the test class to work within the sharing model for the productionenvironment.
  • B. Verify that Test. startTest() Is not Inside a For loop in the test class,
  • C. Add System.runAs() to the test class to execute the trigger as a user with the correct objectpermissions.
  • D. Configure the production environment to enable"Run All Tests as Admin User."
Answer: C
Explanation:
When a test class fails with an "Insufficient privileges" error during deployment, it indicates that the user profile under which the tests are being executed doesn't have the necessary permissions to perform the actions required by the test. In a sandbox, the test might have been running with a different set of permissions compared to the production environment.
By using System.runAs(), you can specify a user context in which the test should run, which allows you to simulate the appropriate permissions. For this to work, you need to create a User instance in your test class with the profile that has the necessary permissions and then enclose the logic of your test within a System.runAs() block with this user.
This is a preferred solution over seeAllData=true, which would give the test access to all data in the production environment, potentially leading to tests that are not isolated and thus less reliable. It's also preferred over changing organization-wide settings or relying on specific setup in test classes, such as making sure Test.startTest() is not inside a loop.

NEW QUESTION # 44
Refer to the code snippet below:

A custom object called Credit_Memo__c exists in a Salesforce environment. As part of a new feature development that retrieves and manipulates this type of record, the developer needs to ensure race conditions are prevented when a set of records are modified within an Apex transaction. In the preceding Apex code, how can the developer alter the query statement to use SOQL features to prevent race conditions within a transaction? A)

B)

C)

D)

  • A. Option D
  • B. Option B
  • C. Option C
  • D. Option A
Answer: D
Explanation:
To prevent race conditions during an Apex transaction, the SOQL query can be modified to include the "FOR UPDATE" keyword. This keyword locks the records that are returned by the query, preventing other transactions from modifying them until the current transaction is complete. This ensures that the retrieved records cannot be changed by another process before the current transaction is completed, thus preventing race conditions. The correct option to use in the code snippet provided is:
[SELECT Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR UPDATE] This will lock up to 50 records of Credit_Memo__c with the specified Customer_Id__c for the duration of the transaction.
FOR UPDATE

Both custom objects have a CurrencylsoCode text field that contains the currency code they should use. If a Catalog's CurrencylsoCode changes, all of its Catalog Items' CurrencylsoCodes should be changed as well.
What should a developer use to update the CurrencylsoCodes on the Catalog Items when the Catalog's CurrencylsoCode changes?
  • A. An after insert trigger on Catalog Item that updates the Catalog Items if the Catalog's CurrencylsoCode is different
  • B. An after insert trigger on Catalog that updates the Catalog Items if the Catalogs CurrencylsoCode is different
  • C. A Database. schedulable and Dazabase.Bazchacle class that queries the Catalog object and updates the Catalog Items if the Catalog CurrencylSoCode is different
  • D. A Database.Schedulable and Database.Batchacle class that queries the Catalog Item object and updates the Catalog Items if the Catalog CurrencylSoCode is different
Answer: D
Explanation:
Use Database.Batchable for handling large data sets. It can efficiently process 100,000 Catalog Items asynchronously and update CurrencylsoCodes.
